Department Profile

Praveen is an Associate Professor of Biomedical Sciences at Cornell University. He received his BA degree from Cornell University and his PhD in Genomics from the University of Pennsylvania. After completing a post-doctoral fellowship at the National Human Genome Research Institute under the mentorship of Dr. Francis Collins, he moved in 2011 to the University of North Carolina at Chapel Hill as an Assistant Professor in the Department of Genetics.  In 2017, he returned to Cornell University as an Associate Professor.


Our research program is centered on the role of non-coding RNAs (in particular microRNAs) in genetic, microbial, dietary, and environmental control of health and disease. The primary disease areas of focus are diabetes, dyslipidemia, gastrointestinal (GI) disorders including Crohn's disease, and most recently, liver/GI cancers. Our laboratory paradigm is highly interdisciplinary, at the interface of genomics, physiology, bioinformatics, and molecular biology.

Active research areas in the lab include:

  • Role of microRNAs and lncRNAs in the regulation of processes relevant to metabolic disease and cancer
  • Contribution of microRNAs and lncRNAs to GI stem cell function and intestinal epithelial homeostasis
  • Utility of non-coding RNAs as candidate molecular stratifiers and prognostic determinants of GI diseases such as Crohn's
  • The role of microRNAs in conferring regulatory stability in the liver, intestine, and pancreatic islet in the face of environmental perturbations (diet, microbes, toxicants)
  • Novel forms of intercellular communication in health and disease via regulated transfer of small RNAs
