Dr. Patrick D. Gajewski is an associate researcher at IfADo in the research group Aging in the department of Ergonomics. He received Diploma in biological psychology and PhD in psychology at the University of Düsseldorf and habilitation in psychology at the Technical University of Dortmund. His main research focus is cognitive aging and interventions reducing cognitive decline in aging. In particular, cognitive aging is due to a number of exogenous or environmental factors like type of work, lifestyle, mental and physical activity or nutrition during the lifetime on the one hand, and endogenous factors like individual genetic diversity, latent diseases of the central nervous system, e.g. inflammatory processes or infectious diseases on the other. His interdisciplinary research aims at investigating systematically these factors by using psychometric and neuroscientific measures.
