Dr. Marquardt's primary research aim is to identify innovative targets for the treatment of internalizing disorders, particularly anxiety and depression. His research employs empirically validated measurement models of emotion, personality, and psychopathology, which he maps onto neurobiological variables. Through his research, Dr. Marquardt consistently finds that dimensional measures of emotion provide a better explanation for individual differences in cognition and neurobiological systems than traditional categorical psychiatric diagnoses. Dr. Marquardt brings expertise in psychometrics, multivariate statistics, and cognitive neuroscience. Currently, his active investigations focus on the MMPI and MPQ families of instruments, PTSD, and electroencephalographic (EEG) markers of attention and cognitive control. Furthermore, Dr. Marquardt applies longitudinal models of resilience from the developmental psychopathology literature to evaluate the effects of recent adverse life events among adults.
