Leslie B. Vosshall PhD
Robin Chemers Neustein Professor
Phone: 212-327-7236
E-mail: leslie.vosshall-at-rockefeller.edu

Leslie B Vosshall is the Robin Chemers Neustein Professor, Head of the Laboratory of Neurogenetics and Behavior, and Director of the Kavli Neural Systems Institute at The Rockefeller University. She is a molecular neurobiologist known for her work on the genetic basis of chemosensory behavior in both insects and humans. Her notable contributions to science include the discovery of the insect odorant receptors, and the elucidation of general principles regarding their function, expression, and the connectivity of the sensory neurons that express them to primary processing centers in the brain. She founded the Rockefeller University Smell Study in 2004 with the goal of understanding the mechanisms by which odor stimuli are converted to olfactory percepts. Vosshall received an A.B. in Biochemistry from Columbia University in 1987 and a Ph.D. from Rockefeller University in 1993. Following postdoctoral work at Columbia University, she joined the Rockefeller faculty in 2000. She is the recipient of the 2008 Lawrence C. Katz Prize from Duke University, the 2010 DART/NYU Biotechnology Award, the 2011 Gill Young Investigator Award. Vosshall is an elected fellow of the American Association for the Advancement of Science, and a member of the National Academy of Sciences. Photo: Trevor Sorrells (2018)

Maria Elena (Ellen) De Obaldia PhD
Helen Hay Whitney Postdoctoral Fellow
E-mail: mdeobaldia-at-rockefeller.edu

Ellen earned an A.B. with high honors in Biology from Harvard College in 2008. As an undergraduate, she studied in vivo vasculogenesis from human cord-blood derived progenitor cells in Joyce Bischoff's laboratory at Children's Hospital Boston. She went on to complete PhD training in Immunology, mentored by Avinash Bhandoola at the University of Pennsylvania School of Medicine, graduating in 2014. Ellen was awarded the Tom Kadesch Prize in Genetic Research and the Saul Winegrad, MD Outstanding Dissertation Award for her thesis work on mechanisms of T cell lineage commitment. Ellen joined the Vosshall Lab in 2014, with a broad interest in studying the interactions between anthropophilic disease vector mosquitoes and their mammalian hosts, from which they must obtain a blood meal in order to reproduce. Specifically, Ellen is investigating why Aedes aegypti mosquitoes prefer skin odor from some humans over that of others. Further, she wants to understand the mechanistic basis for the preference of Aedes aegypti for biting humans over other non-human mammals, using novel in vivo and ex vivo animal models. Ellen envisions that the answers to these fundamental questions will suggest novel ways to deter mosquito biting behavior and disease spread. Ellen is the recipient of a 2014 Harvey L. Karp Discovery Award, is a 2016 Helen Hay Whitney Foundation Fellow, and is a recipient of a 2017 pilot award from the Rockefeller University Center for Clinical and Translational Science (RUCCTS), supported by the NIH National Center for Advancing Translational Sciences (NIH/NCATS).
