I am originally from Bulgaria, but moved to the U.S. at the age of 8 and grew up on the East Coast. In 2009, I completed a B.S. in biomedical engineering at Rensselaer Polytechnic Institute. Shortly after graduating, I received an Intramural Research and Training Award and joined Dr. William Gahl’s group at the National Institutes of Health (NIH) to study rare and undiagnosed genetic diseases. In 2013, I left the NIH to begin my graduate training in biomedical sciences at UCSF. My primary research interests are at the intersection of transcriptional regulation and human disease.

…when I am not working I am usually playing soccer.
