Ramesh Nair, PhD
2014-present: Ramesh, the Acting Director of Bioinformatics at SCGPM, heads up the Bioinformatics-as-a-Service resource for the GBSC, and is the bioinformatician-in-residence for the CIRM-initiated Stem Cell Center of Excellence (CESCG). He is responsible for diverse bioinformatics needs for the Center Initiated Projects and its extensive collaboration network. Prior to joining SCGPM, Ramesh was a Bioinformatics Analyst at Center for Cancer Systems Biology (CCSB) where among other things, he was the sole developer of next-generation sequencing (NGS) pipelines for genome sequencing (Exome-Seq) applied to follicular lymphoma and transcriptome sequencing (RNA-Seq) applied to lung cancer tumor microenvironment. Prior to joining Stanford, he was a Senior Scientist at various Biotech firms in Bay Area, including Cobalt Biofuels, Iconix BioSciences (now Entelos), Lynx Therapeutics (now Illumina) and DuPont. Ramesh has a PhD in Chemical Engineering from Northwestern University and MTech in Biochemical Engineering and Biotechnology from Indian Institute of Technology Delhi.
Jina Song, PhD
2018-present: Jina Song is a Bioinformatics Data Analyst at SCGPM. Her research interests are in the areas of statistical analysis, mathematical modeling and machine learning in computational systems biology. Prior to joining SCGPM, Jina worked as a postdoctoral researcher in Biostatistics & Computational Biology Branch in National Institute of Environmental Health Science (NIEHS/NIH), where she analyzed ChIP-seq data in cancer research. She was also responsible for the computational modeling parts of various projects related to plant systems biology at North Carolina State University (NCSU). Jina has a Ph.D in Systems Biology Research lab. In Electrical and Computer Engineering from NCSU.
Wenyu Zhou, PhD
2019-present: Wenyu is a Bioinformatics Scientist at SCGPM dedicated to BaaS. She recently finished her post-doctorate training with Dr. Michael Snyder at Stanford University. With Dr. Snyder, she studied Type 2 Diabetes (T2D) and utilized multi-omic techniques to measure both host and microbial molecular changes over time and to understand underlying associations with the disease onset and development. She led the Integrative Personal Omics Profiling (iPOP, http://med.stanford.edu/ipop.html) project over the last five years, and has expertise in analyzing different types of high-throughput data (NGS, mass-spec based and others) and applying statistical modeling and visualization techniques. Wenyu has first-authored research articles published in Nature, Cell Stem Cell, Cell Systems, and EMBO Journal, and actively serves as a reviewer for a number of scientific journals in the genomics field. Wenyu received her PhD in Biology from the University of Washington at Seattle in 2012.
Ziye Xing, MS
2018-present: Ziye Xing is a software engineer at SCGPM. His research interests lie in large-scale parallel computing, distributed systems, and data analysis using machine learning techniques. He worked on building a Hadoop ecosystem and HBase database in the cloud when he worked with our center as an intern, and then he fully joined our team to continue developing Hummingbird, an application helps to optimize performance of genomics pipelines on the cloud. He is also helping to analyze genomic data from the VA's Million Veteran Project. Ziye received his Computer Science Masters Degree from UCLA, and did his undergraduate study at Michigan State University, where he contributed to the Ribosomal Database Project.
The bioinformatics team at the Stanford Center for Genomics and Personalized Medicine (SCGPM) is a group of passionate and highly skilled individuals who like solving big problems that face today’s researchers in genomics-driven health care.
