Project 1 Hand-Eye Coordination Algorithm for Minimally Invasive Surgical Robot

Typical minimally invasive surgical robots are generally used for remote operations. This involves doctors carrying out surgical operations according to endoscopic images, through a handheld device to control the distal surgical robot. This approach has a variety of advantages, the robot is more stable and accurate than the doctor's hand and it’s very useful for surgeries that need to be operated in the X-ray environment, such as some orthopedic surgeries. The sharing of genuine medical resources can be realized in the future for doctors and patients who are isolated by geographical location. Excellent doctors can be accessible to people around the world. The hand-eye coordination algorithm studied in this project is established by mapping the correlation between hand movements and the endoscopic images to enhance the surgeon's presence. Hand-eye coordination, including control of the robot, coordinate system transformation and so on, is one of the core technologies used in the remote operation problem.

Project 2 Optimal Design of Neural Electrode Coating

Neural electrode coating is aimed at assisting people with neurological disabilities by stimulating or recording neural tissue and creating a link between the nervous system and the outside world. Recent progress in nanotechnology has been applied to improve neural electrode coating with nanomaterials, such as conducting polymers, carbon nanotubes, silicon nanowires and hybrid organic-inorganic nanomaterials. This is done to enrich the application of neural electrodes, reduce the damage to neural tissues and to make the electrode work longer. A dierent combination of materials, dimensions for coating and manufacturing processes can be considered for change. In the project, both software simulations and experiments are possible. You can choose to do simulations of your own design or take advantage of the advanced manufacture and test technology at the university to conduct experiments. The objective of the internship is to contribute to our long-term project with new ideas and designs based on what we are doing now.

Project 3 Key Technology in Endoscopic Surgical Robotics Based on Augmented Reality

As a modern minimally-invasive surgery, endoscopic techniques are widely used in the eld of surgery. However, currently orthopedic robots are only applicable to traditional open surgery, their working principles, operation mode, as well as the software and hardware systems simply do not apply to endoscopic surgery. In this project, some leading-edge algorithms regarding multi-modal image registration, automatic segmentation, high quality visualization, and precise planning are proposed for important anatomical structures in the musculoskeletal system. Subsequently, a surgical navigation system based on Augmented Reality is established on the basis of real time segmentation, non-rigid registration and 3D reconstruction for intra-operative ultrasound and endoscopic images. This is aimed at solving problems of soft tissue deformation and tracking. Finally, comprehensive, light, and smart mechanical structures and control systems for surgical robots in endoscopic orthopedics will be designed and integrated with our previously self-developed surgical navigation and robotic system, to achieve the ultimate prototype of “Endoscopic Surgical Robotics Based on Augmented Reality”. The accuracy, eectiveness and reliability of the whole system will be validated through phantom experiments and clinical trials, with the goal of the mass clinical application. The research outcome of this project will promote the personalization, safety, accuracy, and minimalizing the invasiveness of endoscopic orthopedics, thus leading the direction of the international eld of orthopedic robotics.

The treatment of oral diseases, oral and maxillofacial surgery, aims to treat the entire cranio-maxillofacial complex: the anatomical area of the mouth, jaws, face, skull, as well as associated structures. However, the limited intraoperative visibility, especially the anatomical intricacies, makes this type of surgery a challenging procedure. Additonally, the accuracy and stability of the operation is very dicult to guarantee. In this project, the integration of computer-assisted surgical planning, virtual reality, computer graphics and 3D-Printing, the methodology of the design and manufacturing of customized template is presented for oral and maxillofacial surgery, aiming to meet the unique demands of China’s clinical application.

The relationship between hand movements and MUAPt will be analyzed to build a new control model which can realize simultaneous and proportional estimations of multiple degrees-of-freedom (DOF) kinematics. The recording channel conguration of the high-density surface, EMG, including electrode number and spatial distribution, will be optimized to improve the decomposition performance of MUAPt. This project will not only realize the simultaneous and continuous control of prosthetic hand wrist and ngers, but also provide enabling techniques for human-machine interface and dexterous prosthetics with high transmission rate.

Project 13 Soft Robots

Project Description and Objectives Soft robots, dierent from traditional rigid robots, are emerging due to their ability to deform large amounts for adaptive and compatible interactions with their environment. To achieve this ability, the robots are usually made of soft functional material based actuators (such as, dielectric elastomer actuators, pneumatic actuators, shape memory polymer actuators). Until now, dierent soft robots have been presented for grasping, crawling, swimming and jumping. However, the design, modeling and control of soft robots is still a challenge. This project mainly focuses on investigating soft sensing and the actuation principle, design of the bioinspired soft mechanism, and control of soft robots. We also aim to employ the developed soft robots for wearable and rehabilitation applications.

The project oers a chance for students to apply cutting edge microwave concepts to the design of practical antennas.

Project 16 Neural Patterns Smong Different Cultures for EEG-based Emotion Recognition

Emotion plays a signicant role in our daily life and has been described as the ‘driving force’ behind motivation, endowing meaning to all human interactions. As we all know, various environments and cultures inuence a human’s physical peculiarity, the way humans think and many other aspects. Humans all over the world may have dierent emotional patterns or possess similar emotional characteristics. Recently, multicultural research concerning emotion recognition has provided explanations for cross-cultural dierences as well as similarities. This project mainly investigates the emotional neural patterns among dierent cultures using EEG signals. As we all know, facial expressions for dierent emotions are similar all over the world regardless of culture. The study aims to nd out whether people sharing the same emotion have similar neural patterns and to discover more facts about human emotions.

Project 17 Model Tests on Marine Renewable Energy Devices

Project 20 Near-infrared Spectroscopy for Discrimination Between Polymethyl Methacrylate and Methyl Methacrylate

With the growing use of plastic around the globe, especially in electronic devices, rapid and autonomous plastic sorting processes have become increasingly necessary in the recycling industry. Near-infrared (NIR) spectroscopy has been proven to be an eective tool for sorting in the recycling, agriculture and pharmaceutical elds. However, there is limited information on its eectiveness in sorting two widely used plastics with very similar reectance spectra’s, polymethyl methacrylate (PMMA) and methyl methacrylate (MMA). This study initially introduces spectroscopy as a whole and then explores the use of NIR spectroscopy for discriminating between PMMA and MMA (in the wavelength range of 900-1700 nm). The chemometric method of principal component analysis (PCA) is used to create a model which can be used in the future for automated sorting purposes.

Project 21 Fabrication of Superhydrophobic Nanofiber Membrane and its Application for Removal of Nonvolatile Contaminant in Water

Although Membrane Distillation (MD) has been extensively studied for desalination, it has other applications such as removing diverse of solutes from water and concentrating non-volatile substances. Emerging contaminants, such as various pharmaceutical or personal care products (PPCPs), could give rise to adverse ecological and human health impacts. MD oers the possibility of producing a clean stream while concentrating emerging contaminants and pathogens present in wastewater in order to facilitate their chemical elimination. MD is a thermally driven separation process, driven by vapor pressure dierences existing between the porous hydrophobic membrane surfaces. However, the current MD membrane still suers from limitations such as low permeate ux rates and the wetting of the pores during the MD process. In this study, the super hydrophobic property of the membrane is obtained by adding surface-modifying macromolecules into the dope solution. The electrospinning technique is used to fabricate this kind of nanober membrane.

Project 22 Cloning and Functional Characterization of Rice Male Sterile Genes

The life cycle of owering plants alternates between diploid sporophyte and haploid gametophyte generations. Male gametophytes develop in the anther compartment of the stamen within the ower and require cooperative functional interactions between gametophytic and sporophytic tissues. During male reproductive development numerous biological events occur, including cell division, dierentiation and degeneration of somatic tissues. The degeneration consists of four concentric cell layers surrounding and supporting reproductive cells as they form mature pollen grains through meiosis and mitosis. To understand the mechanisms of male plant reproduction, we are combining systematic biology (genomics, transcriptomics, proteomics, metabonomics) with other approaches such as genetics, cell biology, biochemistry, and structure biology. This is done to elucidate the molecular mechanism underlying each biological process of male reproduction, such as cell-to-cell communications, programmed cell death, and fatty acids metabolism.

Project 23 Molecular Mechanism Controlling Inflorescence and Spikelet Development in Rice and Barley

Rice and barley, model grass plants, form specialized morphology of inorescence and spikelet, which determine grain yield. Using various approaches such as forward and reverse genetics, biochemistry, cell biology etc. we are investigating the molecular mechanisms such as MADS box genes and the regulatory network involved in the morphogenesis and development of inorescence and spikelet in rice and barley.

Project 24 Molecular Characterization of GMOs

As more and more transgenic crops such as maize and soybeans have been approved and consumed as foods and feeds, people have become increasingly concerned about the safety of transgenic organisms. Molecular characterization of transgenic organisms is the basis of safety assessments of transgenic organisms. We are developing new detection methods to identify the changes that occur at genomic, transcriptomics, proteomics and metabolic levels. The changes will be compared to the changes between the transgenic line and non-transgenic control line and between the transgenic line and conventional cultivated lines, laying a foundation for safety assessments.

Project 25 The Study of the Paternal Transgenerational Effects of Tobacco Smoking/nicotine Via the Underlying Epigenetic Mechanisms.

According to current studies, some paternally acquired traits induced by environmental factors can be retained in gametes and passed down to the ospring. The molecular mechanism underlying this phenomenon however remains unclear. Our previous studies showed that tobacco smoking/nicotine treatments can lead to abnormal sperm function, and these abnormalities have been associated with DNA methylation changes within some gene promoter regions. We also found that nicotine induced a depression-like phonotype in mice and elevated the DNA methylation level within the CpG island shore region of mmu-miR-15b in murine sperm. This epigenetic information is then passed down to the ospring and imprinted in the brain tissue leading to hyperactivity in the lial generation of mice. Based on prior studies, our project intends to rstly establish a mouse smoking and nicotine treatment model. Secondly, analyse the DNA methylation patterns and sncRNAs expressive prole in the spermatozoa of smoking and nicotine treatment mice and in the brain tissue of the ospring. Our project mainly involves the epigenetic information retained in murine mature spermatozoa after nicotine treatment, such as DNA methylation and sncRNAs. These may inuence the embryonic development of the ospring. The molecular mechanism underlying this paternal transgenerational eect on the ospring mice will also be illustrated, which can provide new evidence of the eects of paternal smoking on the physical and mental health of the ospring.

Project 26 Epigenetic Effects and Molecular Mechanisms of Pebp1 Gene in Spermatogenesis

Prior studies have demonstrated that testicular Pebp1 gene defects in male mice can lead to a signicant decline (90%) in fertility. Our preliminary experiments have also found that nicotine-induced hypermethylation of pebp1 genes leads to reduced expression levels, thereby aecting the ERK1 / 2 activity. This is accredited to the fact that its expression level positively correlates with abnormal sperm development. However, little is known about the molecular mechanisms. Dependent on the results, the project intends to research the PEBP1regulational pathway, PEBP1- signaling pathways - molecule eectors - cellular events, in spermatogenesis events such as, migration, division, apoptosis and sperm decapacitation using pebp1 over-expression, RNA interference, uorescence in situ hybridization, spermatogonial stem cell transplantation, and knockout technical methods. Finally, we will systematically explain why PEBP1 regulations and mechanisms in spermatogenesis events on the cells in vivo knockout mice levels. The goal of the project is to investigate the eects of environmental factors and epigenetic mechanisms in spermatogenesis, provide molecular targets for clinical diagnosis and treatment of male infertility sperm. It is available for innovative theory and practical application.

Project 27 Comparing Thousands of Big Genomes

With the rapid growth of genomics sequence data, it’s becoming more challenging to compare tens or hundreds of genomes over long or short evolutionary distances. Therefore, new methods demand the improvement of the comparison of many genomes. In this project we are going to develop new methods to compare and visualize many big eukaryotic genomes with various evolutionary distances. Main tasks during the internship will be: 1) Find an existing method to compare a model organism genome to more than 100 other genomes and 2) visualize the comparison results.

Project 28 Computer Aided Drug Design

As drug development faces increasing challenges, computer aided drug design is a vital method in speeding up the discovery rate of new drugs. Therefore, training undergraduate students to master this method can help them to understand the process of drug design and develop new methods. In this project we are going to train the students with 3D-QSAR, molecular docking, and molecular dynamics simulation and construct a robust prediction model. Main tasks during the internship: 1) Construct a robust drug prediction model for several diseases and 2) Compare with the previous works.

Project 29 Protein-Protein Interaction

Years of exploration and study into cellular, molecular and biochemical biology, structural and biophysical contexts have produced a noteworthy compilation of knowledge on the physiochemical properties and function of individual proteins. Nonetheless, a single protein executing a function alone is very rare and is not often witnessed. The systemic interactions of dierent proteins in dierent biological processes, ranging from normal to disease phenotypes, play a signicant role. The interface interactions of dierent proteins ensure the systemic coordination of cellular processes and may lead to dierent disorders or diseased phenotypes. Many in vitro methods for the investigation of PPI are widely used, such as protein-fragment complementation assay, coimmuno-precipitation, TAP tagging, yeast two-hybrid and X-ray crystallography. Fortunately, the use of in silico protein-protein interaction methods have greatly reduced the costs, time and eorts of wet experimentations. These processes such as structure and sequence-based approaches, in silico two hybrid chromosome vicinity, gene fusion, phylogenetic tree construction and proling, and microarray gene expression-based methodologies were developed. The detailed study of PPIs has accelerated the mapping of functional pathways to illustrate the molecular mechanisms of cellular routes and also to identify new drug targets for the treatment of specic diseases. Therefore, this project will thoroughly investigate the interactome of dierent phenotypes and extract possible information such as: (i) Identication of key nodes in the DEGs interactome that could act as possible drug targets acting as hub node. (ii) Meta-analysis of large PPI networks to discover universal biomarkers; (iii) Understanding the Gene regulatory network; (iv) Identication of protein-protein interface and their MD study to understand the interaction mechanism of two protein; (v) Identify the key transcription factors in the disease phenotype; (vi) Targeting identied drug targets for possible discovery of potential inhibitors.

Project 30 Metabolic Regulation and Engineering of Medicinal Plants

China has a great availability of medicinal plants. Our project mainly focuses on metabolic regulation and the engineering of medicinal plants, such as Artemisia annua and Catharanthus roseus. Among them A. annua has obtained great attention due to the antimalarial agents: artemisin and its derivatives. Malaria is one of the most serious health problems in human history and was responsible for more than 600,000 deaths last year. Artemisinin-based combination therapies (ACTs) are recommended by WHO as the best choice for acute malaria as it has saved millions of lives in Africa. The Chinese pharmacologist Youyou Tu received the 2015 Nobel Prize in Physiology and Medicine for her contribution to the artemisinin isolation. Moreover, artemisinin and its derivatives have been found to have antiviral, anticancer, and antischistosomal activities, which makes artemisinin a promising natural multifunctional product. Plants of A. annua are the main commercial source of artemisinin. Unfortunately, the supply is restricted by the low amounts of artemisinin at a range of 0.1%-1 % dry leaf weight of A. annua, which results in a high cost of this eective product that most of the malarial victims in Africa cannot aord. In order to improve the artemisinin content in A. annua by reducing its production cost, our project focuses on metabolic engineering of A. annua plants using three main strategies: overexpressing artemisinin biosynthetic pathway key enzyme genes in A. annua, blocking artemisinin biosynthesis competitive pathway key enzyme genes and transcriptional regulation of artemisinin biosynthesis.

Project 31 Ecological Stoichiometry of Fagaceae Trees and Parasite weevil larvae at Soil Phosphorus-Rich Sites in Subtropical China

Subtropical areas generally have soil P-poor ecosystems due to strong leaching under high temperatures and precipitation. Fortunately, lots of P-rich ores are distributed throughout the Hubei, Hunan, Yunnan, Guizhou and Sichuan etc. provinces in China, forming typical soil P-rich ecosystems. This provides an ideal situation for studying the ecological signicance of P-rich soils. In this project, Fagaceae trees and parasite weevil (Curculio davidi) in the P-rich ores and adjacent P-poor areas, in Central Yunnan Plateau, have been selected as the study subjects for investigating ecological stoichiometry of plants and herbivorous insects by metabolomics. Our main objectives are, 1) to show the relationship between stoichiometric traits and the metabole of Fagaceae trees, revealing the strategy of plant adaptation for varying soil nutrients; 2) to study the origins stoichiometric traits of dierent Fagaceae trees and the relation to soil nutrients; and 3) to show the up-cascade transfer of soil P-rich eects along a parasitism food chain, revealing the response of parasite insects to a variation in environmental nutrients. These results have great implications in understanding the ecosystem properties in subtropical areas in the context of global change.

Project 32 Vegetation and Aerosol Fine Particles (PM2.5)

From previously conducted experiments, basic conclusions have been made that explain the connection between leaf properties and its particulate deposition capacities. Meanwhile, the variation of particles deposited by leaves and formed in air was found but its mechanism was not explained. Thus, to dig deeper the relationship between leaves and its mechanisms, the description of the process of particle variation may help in discovering and understanding how plants work as natural air-pollution lters. This project mainly focuses on two subjects. The rst is to nd more properties to help decide which properties play a bigger role in dust deposition. The second is to gure out the process of particle variation chemically and physically. This project aims to lay a systematical foundation for the aerosol particle deposition of plants and the chemical and physical transformation of particles.

From this program, students can become familiar with the whole industrial process from vine to wine and may discover their future career path in the eld.

Project 34 Ecological Restoration and Eco-design of Urban-rural Fringe in Shanghai

Shanghai is not only China’s but also the world’s economic, nancial, shipping and technology center. An urban-rural fringe is a special area formed during the urbanization process and is characterized by a diverse population, mixed types of land use, drastically reduced ecological lands and degradation of the ecological environment, this is what has taken place in Shanghai. This has formed situations where the city is mingled with the countryside, farmland and industrial adjacent to, woodland and the water systems separated and so forth. Utilizing GIS and other spatial analysis techniques to extract and analyze the transformation of land use, establishing the relationship between spatial patterns and ecological processes of urban-rural fringe in Shanghai.

Project 35 Transcranial Ultrasound Stimulation and Applications

It has been discovered that low intensity ultrasound is able to eectively activate or inhibit the neuronal activities in a specic location, which has a great potential in biomedical applications. Nevertheless, there are still lots of technical issues to be solved, including the roles of the parameters of the ultrasound and the mechanisms of the interactions between ultrasound and neurons. This project aims to explore the mechanisms of transcranial ultrasound stimulation and apply it as an innovative neural intervention tool in neurologic diseases, e.g. stroke, depress or Parkinson’s Disease. The students will join a team of graduate students and research faculty members in this project. The laboratory will oer the opportunity for technical training, human and/or animal experimentation and data analysis.

Project 36 Ribosome Specific Protein-protein Interaction Network Construction for Mycobacterium Tuberculosis

Tuberculosis is the No.1 most in infectious disease based on the direct and indirect mortality rates. Mycobacterium tuberculosis (Mtb) is the main causative agent of tuberculosis, which has caused 9.6 million newly identied active cases and 1.5 million deaths from the disease in 2014. Moreover, the emergence of multidrug resistant (MDR) and extensively drug resistant (XDR) strains of Mtb has increased the threat that this disease imposes on the public health throughout the globe. For Mtb, ribosome is one of the most important targets for antibiotics development. Although the core structure of bacteria ribosome is similar to that of eukaryote, there are signicant dierences of the overall structure and regulation mechanisms. Consequently, the ribosome of bacteria has been used as a direct target for drug screening. In lieu of the above situation, we will try to reveal the ribosome regulation systematically through global protein-protein interaction discovery. By using bioinformatics analysis and initial validation and function analysis, we aim to identify 1-2 Mtb specic ribosomal protein-protein interactions as potential drug targets. This will be done by: 1) Constructing the rst protein-protein interaction network for all the Mycobacterium tuberculosis (Mtb) ribosomal proteins. 2) Identifying 1-2 Mtb specic ribosomal protein-protein interaction as potential drug targets.

Project 37 Mechanisms of New Targets in Tumor Metastasis and Development of Therapeutic Methods

Our lab focuses on searching for drug targets which can inhibit tumor metastasis. Prior work has indicated that AEP has a great eect on breast cancer metastasis. Therefore, future work will focus on searching for small molecule inhibitors of AEP, an antitumor prodrug, and therapeutic antibodies. In addition, the work will provide in-depth understanding of the mechanism of the AEP in a tumor microenvironment and tumor-associated macrophage. This project mainly focuses on searching for the inhibitors of Bcl-2 (including natural products and derivatives), setting up appropriate tumor animal models to study ecacy and the molecular mechanisms of microwave hyperthermia chemotherapy and microwave hyperthermia immunotherapy. Through the usage of clinical trials, our research will provide theoretical support for the new tumor therapy.
