Biography
Dr. Kyriakides collaborates with clinical researchers on numerous research projects and he provides statistical consulting on numerous research protocols. He has been an abstract mentor for young researchers at the International AIDS Conferences since 2012, leads the VACSPCC internship program and is a statistical reviewer for high-impact medical journals (Lancet Infectious Diseases and the Lancet Gastroenterology & Hepatology).
He is the Director at the Department of Veterans' Affairs Cooperative Studies Program (VACSPCC-West Haven) and has worked, as a Senior Biostatistician, on pivotal clinical trials (The OPTIMA Trial, a multi-national HIV/AIDS treatment clinical trial; a surgical clinical trial (The OVER Trial); and a PTSD clinical trial (The VIP-STAR Trial).
Even though his primary research focus is in the area of infectious diseases with particular emphasis on HIV/AIDS and its treatment, he has an interest in the history of medicine, social determinants of health and the socio-cultural dimension of the benefits of Greek/Mediterranean nutrition. He has recently been certified as an Olive Oil Sommelier by the International Culinary Center and the Olive Oil Education Lab in NY City. He is the co-proponent for the establishment of a Yale institute dedicated to the olive tree, its products and their impact on human and planetary health.
