About
My research focuses on identifying the genetic and genomic components for psoriasis, and understanding their biological effect and contribution to disease heterogeneity. I currently direct the Center for Cutaneous Bioinformatics at the University of Michigan, and I am the associate director of the Functional Analytic Core of the P30-funded University of Michigan Skin Biology Disease and Resource Center.
I have been actively involved in coordinating and conducting different genetic and genomic studies to understand the pathophysiology of different immune-mediated disorders including psoriasis, psoriatic arthritis, atopic dermatitis, and cutaneous lupus. By using systems biology approaches, we have revealed robust disease associated signals and candidates for downstream functional assays of psoriasis and facilitated the identification of genetic signature for psoriatic arthritis risk. My research also focuses on the development and implementation of computational pipeline for genomic data to identify novel disease-associated transcripts as well as context-specific inflammatory responses for inflammatory disorders.
