  Nicholas Devanney, PhD  Postdoctoral Researcher

  Nick carried out his undergraduate studies at the University of New Hampshire (UNH), majoring in Biochemistry, Molecular, and Cellular Biology. While at UNH, Nick completed an honors thesis investigating the tumor suppressor p53 in the laboratory of Dr. Charles Walker. After graduating, Nick spent three years as a Research Assistant under the supervision of Dr. Basile Tarchini at the Jackson Laboratory, utilizing novel transgenic mouse models to study hereditary hearing loss and developmental biology of the inner ear. Nick completed his Ph.D. at the University of Kentucky in the laboratory of Dr. Lance Johnson, a lab focused on apolipoprotein E (APOE) - the strongest genetic risk factor for late-onset Alzheimer's Disease. Nick's work tied together APOE's effect on metabolism in microglia with neuroinflammation, a concept known as 'immunometabolism'. Joining the Ellerby lab as a postdoc, Nick is excited to continue to work on APOE, leveraging the lab's iPSC lines. This time around, the focus will be more towards understanding the E2 allele (associated with longevity and neuroprotection) rather than focusing as heavily on the E4 allele (associated with neurodegeneration). In order to take advantage of the tremendous resources available at the Buck, Nick will be co-mentored by Drs. Eric Verdin and Birgit Schilling, allowing him to continue to hone his skills on mass spectrometry and utilize a multi-omics approach to dig further into immunometabolism in AD and aging. Outside of lab, Nick is an avid nature enthusiast and lifelong musician, spending his free time immersed in the outdoors or traveling to concerts.
