I am a transplant here in the south- born and raised in upstate NY

I am an avid NFL fan- rooting on the NY Giants through the good and the bad

I have always been obsessed with the Galapagos Islands, and my wish to go there was granted in 2014. Truly a once in a lifetime experience I recommend for any biologist!


Although not actively conducting any research I do maintain interest in both subject areas in which I have studied:

  1. Elucidation of underlying mechanisms in the development of Type 1 Diabetes among identified “at-risk” individuals. What roles do genes by gene and gene by environment interaction have in determine which genetically predisposed individuals will eventually develop disease, and what protective effects might be preventing other at risk individuals from development.
  2. Understanding the potential role of extracellular vesicles and exosomes in the process of aging by studying the microRNA that is contained in these vesicles.
