Jennie Larkin is a Health Scientist Administrator with the Bioengineering and Genomic Applications Scientific Review Group (SRG) in the Division of Heart and Vascular Diseases of the National Heart Lung and Blood Institute (NHLBI), part of the National Institutes of Health (NIH) (an acronym-rich environment).

Prior to her work at NHLBI, Dr. Larkin was a staff scientist at The Institute for Genomic Research (TIGR) in Rockville, Maryland, working with Dr. John Quackenbush. Prior to that, Dr. Larkin was a post-doctoral fellow at Stanford University and University of California, Berkeley. At Cal, Dr. Larkin worked with Dr. Irving Zucker, performing research in the field of circadian rhythms, melatonin and torpor. Dr. Larkin received her Ph.D. in Biological Sciences from Stanford University in 1996, studying in the laboratory of Dr. H. Craig Heller. She received a M.S. degree in Zoology from University of Washington in 1991. She received her B.A. degree, cum laude with Honors in Biology, from Wellesley College in 1987.

Dr. Larkin has published a number of scholarly papers:
