Department Profile


Andrew Grimson is an Assistant Professor in the Department of Molecular biology & Genetics. He received a B.A. in Genetics at Trinity College Dublin(Ireland) in 1997, and a Ph.D. in Genetics at the University of Wisconsin-Madison in 2004. As a graduate student he worked on the genetics and the biochemistry of nonsense-mediated
mRNA decay, a eukaryotic mRNA decay pathway. In 2004, he joined the Bartel laboratory at the Whitehead Institute for Biomedical Research as a National Institutes of Health Postdoctoral Fellow. His postdoctoral research focused on microRNA-mediated (miRNA) regulation of target mRNAs and the early evolution of miRNAs in
animals. He joined the Cornell faculty in 2009.

Research Description

The Grimson lab focuses on post-transcriptional gene regulation, in particular the identity and function of animal microRNAs and other small RNAs, as well as explorations into novel regulatory functions encoded in the 3' untranslated region (3'UTR).. To address these research areas, we use a combination of approaches, including molecular biology, high-throughput genome-scale datasets (e.g., high-throughput sequencing, microarrays), and computational biology/bioinformatics analysis.
