Shweta Ramdas

Areas of Interest & Expertise

  • Genetic Variation in Human Populations
  • Epigenetics
  • Genetics of Complex Traits
  • Gene Regulation
  • Bioinformatics
  • Genomics


Shweta has earned her Ph.D in Bioinformatics and an M.A. in applied statistics from the University of Michigan and her B.S. in Computational Biology from the National University of Singapore. She did her postdoctoral work in the department of genetics at the University of Pennsylvania.

Her research explores genetic variation in human populations and its role in regulating gene expression and a host of complex traits. She primarily uses bioinformatic and statistical approaches to answer these questions. She is also interested in mining publicly-available data to ask novel biological questions. She is always looking for students interested in applying quantitative methods to biology.
