Himel Mallick

Senior Scientist, Biostatistics

Merck Research Laboratories


I am a computational biologist researching at Merck Research Laboratories (MRL). I use computational methods to generate and validate testable hypotheses that accelerate data-driven discovery. Prior to MRL, I was a postdoctoral fellow of Computational Biology and Bioinformatics at Harvard and a PhD candidate of Biostatistics at UAB.
