Dr. Roman is a developmental biologist and molecular geneticist. She received her postdoctoral training at the National Institutes of Health and was an Assistant Professor at Georgetown University (2002-2006) and the University of Pittsburgh Department of Biological Sciences (2006-2014). She is currently Research Director for the UPMC/University of Pittsburgh HHT Center of Excellence.
The Roman lab studies the autosomal dominant genetic disorder, hereditary hemorrhagic telangiectasia (HHT), which is caused by decreased endothelial bone morphogenetic protein (BMP) signaling and is characterized by a predisposition to development of arteriovenous malformations (AVMs). AVMs are direct connections between arteries and veins that can lead to hemorrhage or stroke if severe shunting or rupture occurs. We use zebrafish models of HHT and molecular, genetic, advanced imaging, and biochemistry approaches to uncover the molecular and cellular errors that lead to AVM development. Out ultimate goal is to develop targeted therapeutics to improve the lives of HHT patients.
Research Interests: Vascular development, hereditary hemorrhagic telangiectasia, zebrafish, BMP signaling, mechanotransduction.

HHT Center of Excellence
HHT is underdiagnosed and undertreated. The goals of the UPMC/Pitt HHT Center of Excellence are to continually raise awareness of HHT; to provide cross-disciplinary coordinated clinical care to HHT patients; and to conduct basic, translational, and clinical research to better understand and treat this rare genetic disease.
