  • Vasilis Vasiliou

    Department Chair and Susan Dwight Bliss Professor of Epidemiology (Environmental Health Sciences) and of Ophthalmology and Visual Science

    Research Interests
    Alcoholism; Aldehyde Dehydrogenase; Diabetes Mellitus; Environmental Health; Glutathione; Gout; Ophthalmology; Genomics

    Vasilis Vasiliou, is Professor and Chair of the Department of Environmental Health Sciences. He received his BSc in Chemistry (1983) and PhD in Biochemical Pharmacology (1988) from the University of Ioannina, Greece. He then trained in gene-environment interactions, molecular toxicology and pharmacogenetics at the Department of Environmental Health in the College of Medicine at the University of Cincinnati (1991-1995). In 1996, he joined the faculty of the University of Colorado School of Pharmacy where he rose through the ranks to become Professor and Director of the Toxicology Graduate Program. Since 2008, he was also Professor of Ophthalmology at the University of Colorado School of Medicine. In July 2014, he joined the faculty of Yale University in his new position.

    Professor Vasiliou has established an internationally-recognized research program that has been continuously funded by NEI/NIH and NIAAA/NIH since 1997. His research interests include mechanisms of cellular responses to environmental stress, gene-environment interactions, alcohol toxicity, pharmacogenetics and the evolution of gene families. His research focuses on the role of aldehyde dehydrogenases, cytochrome P-450s and glutathione in metabolism and disease (specifically, alcohol-induced tissue injury, diabetes, gout and cancer).

    Dr. Vasiliou has published over 140 papers and edited a book on Alcohol and Cancer. He has trained over twenty doctoral and post-doctoral students. Dr. Vasiliou is the editor of Human Genomics and serves on the editorial boards of several toxicology and visual sciences journals.

  • Nicholas Apostolopoulos

    Medical Student

    Nicholas Apostolopoulos is a medical student at Yale School of Medicine, currently completing his medical school thesis in Dr. Vasilis Vasiliou’s lab since the summer of 2016. His research focuses on understanding the role of corneal crystallins ALDH3A1 and ALDH1A1 in ocular physiology and pathophysiology during oxidative stress. His current project aims to address the biological role of crytallin proteins as metabolic enzymes in cornea, lens and retina by utilizing both Aldh3a1/Aldh1a1 knockout and knock-in mouse models. In addition, he studies the role of glutathione (GSH) in the eye development using a mouse strain in which GSH biosynthesis is selectively abolished in surface ectoderm-derived ocular structures. The results so far suggest that GSH plays a critical role in ocular development, and further studies are underway to identify molecular details involved in this process.

  • Georgia Charkoftaki

    Associate Research Scientist in Epidemiology (Environmental Health Sciences)

    Georgia Charkoftaki received her pharmacy degree from the University of Athens, Greece, where she also earned a MSC in drug delivery and a PhD in biopharmaceutics-pharmacokinetics. In August 2013 she moved to the University Colorado Denver to start a postdoc in clinical and translational science, focusing on kidney related diseases. Charkoftaki studied the pharmacokinetics of cyclophosphamide in patients undergoing dialysis and how Vitamin D affects drug metabolism in the kidneys, among other projects. At Yale she has focused on metabolomics working with Waters Xevo G2 QTof and molecular biology. Her main project is a study the importance of aldehyde dehydrogenases (ALDHs) on cancer and diabetes and the discovery of new potential drug targets.

  • Ying Chen

    Research Scientist in Epidemiology (Environmental Health Sciences)

    Research Interests
    Digestive System Diseases; Disorders of Environmental Origin; Nervous System Diseases; Nutritional and Metabolic Diseases

    Ying Chen has a broad background in environmental genetics and molecular toxicology, with specific training and expertise in redox biology, oxidative stress related disease and transgenic animal models of glutathione (GSH) deficiency. Her research in the past over ten years has focused on understanding the mechanistic roles of GSH redox homeostasis in human disease conditions related to environmental (including dietary) exposures. Other ongoing research projects in the Vasiliou lab include studies of: (i) the mechanistic roles of ALDH1B1 in alcohol-associated colon cancer, and (ii) the functional roles of ALDH1A1/3A1 in corneal pathophysiology.<_o3a_p>
