Research Interest: Within the fields of computational biology and bioinformatics, Professor Chen seeks to apply computer algorithms and mathematical methods to answer questions in biology and medicine, specifically in studies of human genetics, proteomics, and genomics. His research includes (1) large-scale sequence analysis for the next generation sequencing data, (2) analysis of genetic variations of the human genome for their relationships to human diseases, (3) studies of functions and dynamic of large-scale biochemical networks inside the cell, and (4) identification of proteins through analyzing mass spectrometry data.
Short Bio: Professor Chen is currently a professor of biological sciences, computer science, and mathematics at USC. Before joining USC in 2000, he had been a lecturer of genetics at Harvard University, working as a research fellow in George M. Church’s Laboratory. He obtained his Ph.D. degree in computer science from SUNY Stony Brook in 1997, and B.E. degree in computer science and technology from Tsinghua University in 1993.
