Dr. Tracey Petryshen, Ph.D., scientific advisor

Petryshen_076_crop
Dr. Tracey Petryshen is an Associate Professor of Psychiatry at Harvard Medical School and an Associate Member of the Broad Institute of MIT and Harvard in the United States.  She obtained her Ph.D. degree in Medical Sciences (Medical Genetics) at the University of Calgary in Canada in 2001 for research on the genetic basis of dyslexia using family linkage and association methods. From 2001-2005, she carried out postdoctoral research training in psychiatric genetics with Dr. Pamela Sklar at the Broad Institute of MIT and Harvard.  During that time, her research focused on schizophrenia and bipolar disorder using genetic association and postmortem brain gene expression approaches, as well as mouse quantitative trait locus (QTL) mapping of psychiatric intermediate phenotypes. In 2005, she was appointed an Instructor of Psychiatry at Harvard Medical School and she established a research laboratory in the Center for Human Genetic Research at Massachusetts General Hospital in Boston. In 2009, she was promoted to Assistant Professor of Psychiatry and in June 2015 to Associate Professor.  From 2007-2012, Dr. Petryshen directed the Behavioral Neurogenetics Program in the Stanley Center for Psychiatric Research at the Broad Institute while also maintaining her academic laboratory at Massachusetts General Hospital.  Dr. Petryshen’s research focuses on the genetic basis and treatment of major psychiatric disorders including schizophrenia, bipolar disorder, depression, and compulsive disorders.  She is specifically interested in understanding how genetic changes perturb brain function and manifest as behavioral and cognitive abnormalities, and how these abnormalities can in turn be attenuated by clinical medications and novel small molecules targeting biochemical and epigenetic mechanisms implicated in psychiatric illness. Her laboratory utilizes human populations and animal and cellular model systems in combination with genetic association, behavioral neuroscience and pharmacology, biochemistry, and bioinformatics approaches.

Prof. Dr. Wiebe Kruijer, Ph.D., scientific advisor

wiebekruijer
Wiebe Kruijer (1951) studied Chemistry/Biochemistry and Pharmacy at the University of Groningen, The Netherlands, where he graduated in 1978. He obtained his Ph.D. degree in Physiological Chemistry (nucleotide sequence analysis of wild-type and mutant genes encoding adenovirus DNA binding protein) in 1983 at the University of Utrecht, The Netherlands.  He then worked as a (senior) Research Associate at the Molecular Biology and Virology Laboratory, The Salk Institute for Biological Studies, San Diego, USA (1983-1985) and at the Hubrecht Laboratory, Netherlands Institute of Developmental Biology (NIOB) of the Royal Academy of Arts and Sciences, Utrecht (1985-1993). From 1993 to 2006, he was Professor of Developmental Genetics at the Department of Biology, Faculty of Mathematics and Natural Sciences, University of Groningen. From 2003 until present, he was Professor and continues as Emeritus Professor in Molecular Cell Biology, Faculty of Science and Technology, University of Twente, The Netherlands.
