Dr. Strauss will be reviewing applications for the admission of a graduate student for fall 2019.
Clinical Affective Neuroscience Laboratory (CAN Lab): https://ugacanlab.com
Dr. Strauss received his B.S. in Psychology from UGA (2002) and PhD in clinical psychology from UNLV after completing his clinical internship at the University of Illinois-Chicago (UIC), Department of Psychiatry (2008). He then completed a two year NIMH funded postdoctoral fellowship at the Maryland Psychiatric Research Center under the mentorship of Drs. Jim Gold and Will Carpenter (2008-2010) and was promoted to tenure track Assistant Professor of Psychiatry at the University of Maryland School of Medicine in 2010 after receiving a K-23 grant from NIMH. In 2013, he moved to the Department of Psychology at Binghamton University (State University of New York) and then to his current position in the Department of Psychology at the University of Georgia in 2017 where he directs the Clinical Affective Neuroscience Laboratory and Georgia Psychiatric Risk Evaluation Program (G-PREP). He has authored over 120 publications, and his research has been recognized by several awards, such as the Early Career Award from the National Academy of Neuropsychology, Early Career Award from the American Society for Clinical Psychopharmacology, Wechsler Early Career Award for Innovative Research on Cognition from the American Psychological Foundation, and Young Investigator Awards from the International Congress on Schizophrenia Research and the Schizophrenia International Research Society. His lab has been funded by the NIMH, NARSAD, VA MIRECC, APF, NSF, and several internal mechanisms. He serves on the editorial boards of Schizophrenia Bulletin, Journal of Abnormal Psychology, and Clinical Psychological Science.
Schizophrenia; psychosis; anhedonia; predictors of conversion to psychosis in high-risk youth; emotion; reward; social cognition
Research in the CAN lab takes a translational approach to studying various aspects of reward and emotion in schizophrenia, relying on theoretical frameworks and methods from the field of affective neuroscience (e.g., EEG/ERPs, eye tracking, pupillometry). Traditionally, these studies have focused on the mechanisms underlying negative symptoms of schizophrenia (e.g., avolition, andhedonia, and asociality). Examples of specific topics include examining whether abnormalities in different components of reward processing (e.g., reinforcement learning, effort-cost computation, value representation, action selection) and cognition-emotion interactions (e.g., memory, attention) predict the severity of negative symptoms using a variety of methods. More recently, the lab is also investigating whether abnormalities in emotion and reward processing predict conversion to psychosis in adolescents and young adults at clinical-high risk for developing a psychotic disorder (i.e., the prodromal phase). We are also developing novel clinical rating scale and mobile technology based assessments of negative symptoms in adults with schizophrenia and youth at clinical high-risk for psychosis.
Philosophy of Graduate Training:
My ultimate goal as a mentor is to prepare my graduate students to pursue their chosen career paths in Psychology. As part of this process, I encourage my students to develop a sound theoretical knowledge base in our area of work, gain methodological expertise in the use of cognitive neuroscience methods (e.g., ERP, eye-tracking), build basic research skills (e.g., programming, writing, statistics), and develop strong clinical abilities that will facilitate their clinical research and practice (e.g., diagnostic and symptom interviewing, neuropsychology). I emphasize the importance of developing a niche area and help my students plan and design a series of independent studies that build upon one another, with the goal of creating their own independent program of research. I also invest time in the professional development of my students via regular meetings to discuss strategies for success at different stages of academic careers, and by encouraging them to attend scientific meetings where they can present research and make connections with others in the field. Students who plan to pursue a career in psychosis research will be a strong fit for this lab.
