Treasurer: Andreas Kateifidis, MD PhD

Affiliation: Vertex Inc., Boston, MA


Andreas obtained his medical and doctoral degrees from the University of Crete in Greece and completed an MBA in Health Sector Management at Boston University, USA. During his doctoral studies, he worked at Whitaker Cardiovascular Institute at Boston University where he investigated the in vivo and in vitro functions of mutant forms of apolipoprotein A-I to determine how structural changes affect plasma cholesterol and triglyceride levels and their contribution to atherogenesis. He additionally developed a method for purification of human apolipoproteins. He is currently a Manager in Process Management and Business Analytics at Vertex Pharmaceuticals Inc. Andreas was introduced to HBA-USA in 2011 and since 2017 he has been serving as Councillor.

General Secretary: Alexandra Touroutoglou, PhD

Affiliation: Harvard Medical School, Boston, MA

Alexandra Touroutoglou, PhD is an Assistant Professor of Neurology at Harvard Medical School. She leads neuroimaging research at Massachusetts General Hospital and the Athinoula A.
