Dr. Zhang is currently an associate professor of the Department of Genetics and Genomic Sciences and a member of Institute of Genomics and Multiscale Biology.
Dr. Zhang’s extensive experience in electrical engineering, computer science and computational biology empowers him to build up highly predictive models for very complex data from handwritten document images to large-scale cancer genomic data. Over the past few years, Dr. Zhang has developed and significantly contributed a series of influential gene network inference algorithms which have been extensively used for identification of novel pathways and gene targets, as well as development of drugs for a variety of human diseases such as cancer, atherosclerosis, Alzheimer's, obesity and diabetes. His latest research that sheds a new light on targeted therapies against breast cancer was featured by the Second AACR International Conference on Frontiers in Basic Cancer Research (San Francisco, September 14-18, 2011). His recent work on predicting genetic interactions was identified by Nature Biotechnology as one of the breakthroughs in the field of computational biology in 2010. The discovery of a gene cluster that is causally linked to obesity and diabetes was highlighted in Nature in 2008. His early research on image pattern recognition significantly contributed to several large-scale pattern recognition systems including U.S. Handwritten Address Identification System which has been adopted by US Postal Office. Dr. Zhang was a recipient of the Best Paper Award of ICDAR 2003 ─ the Seventh International Conference on Document Analysis and Recognition.
As a prolific researcher, Dr. Zhang has published a number of high profile papers in Nature, Nature Genetics and PNAS. As of December 2011, his publications have been cited 2750 times, according to Google Scholar. Furthermore, he has been a leader of more than a dozen projects to identify novel drug targets for several pharmaceutical companies.
Identification of Synthetic Lethal Interactions for Cancer Therapy
Identification of synthetic lethal (SL) interactions in human disease like cancer has a great potential to improve targeted therapies by targeting only genes having SL interactions with those mutated genes. Improved high-throughput technologies for drug and genetic screens enable genome-wide screen for genes sensitizing drugs. However, testing all possible combinations of hundreds of cell lines and thousands of compounds is infeasible and unaffordable in the foreseen future. Therefore, development of high performance classifiers that can effectively predict which genes sensitize which drugs for a given cell line will significantly reduce the number of experiments and thus greatly shorten the cycle of developing effective therapeutics.
Autonomous and Real-time Classification/Prediction Systems for Diagnosis and Treatments (ARCPS)Enormous data from each single patient is being generated but it remains challenging how to make best use of the information for personalized medicine. ARCPS will take as inputs all pathological, clinical, genetic, genomic, proteomic, and metabolic information to classify patients, predict disease progression, determine drug response, and decide optimal treatments. Given the multi-modal nature of the input data, those complex high-dimension data types such as image, DNA, mRNA, protein and sequencing need go through different feature extractors to yield meaningful features for training and classification/prediction.
Reconstruction and Analysis of Multiscale Biological NetworksAdvanced algorithms for reconstructing and analyzing multiscale biological networks are being developed to effectively and efficiently uncover novel targets, pathways and mechanisms driving complex human diseases including cancer, obesity, diabetes, cardiovascular and neurodegenerative disease. These data-driven drivers and pathways can be used to establish global driver-disease and pathway-disease connectivity maps that will be further utilized to develop testable hypotheses for laboratory and/or clinical validations.
