Jiang Qian, M.S., Ph.D.
Associate Professor of Ophthalmology
Research Interests: Retinal gene regulation
Jiang Qian, Ph.D., is an associate professor of ophthalmology at the Wilmer Eye Institute. His research focuses on retinal gene regulation and the application of bioinformatics to the study of gene expression and regulation.
Dr. Qian received an M.S. in computational biology from Shanghai Biochemistry Institute in Shanghai, China, and a Ph.D. in physical chemistry from the Max Planck Institute for Polymer Research in Mainz, Germany. He then completed a postdoctoral fellowship in bioinformatics at Yale University.

Research & Publications
We are working on a number of research projects that all are related to applying bioinformatics approaches to the study of gene regulation, with particular but not exclusive attention to the regulation of retinal gene expression. We have performed large-scale computational analysis of transcription factor (TF) interactions both in the yeast S. cerevisiae and human tissues. The identified TF interactions can help in our understanding of gene regulation and tissue specificity in eukaryotic systems. In a recent project, we collaborated with Drs. Heng Zhu and Seth Blackshaw’s labs to work on large-scale identification of human protein-DNA interactions.
We are also interested in studying aspects of post-transcriptional gene regulation. In one project our analysis generated data that suggests that the interaction patterns between TFs and microRNAs can influence the biological functions of microRNAs.
Another area that we are studying concerns epigenetic gene regulation. We took advantage of available genome wide data sets of nucleosome positions to analyze the rules that determine nucleosome positioning, and their effects on biological functions.
