Alex Cohen is a licensed clinical psychologist who focuses on understanding and improving the lives of individuals with serious mental illnesses. His work focuses on adapting biobehavioral technologies, notably automated computerized analysis of natural behavior, for assessing a wide range of clinical issues, including suicidality, depression, psychosis, mania and anxiety. His work has been featured in top psychology and psychiatry scientific journals, and he has received funding at the state, federal and international levels. For his efforts, he was recently awarded the 2016 LSU Rainmaker award for mid-career scholar.
He is currently adjunct at Pennington Biomedical Research Center and LSU Health Sciences, and he maintains a team of 6 doctoral students and 15+ undergraduate research assistants. His clinical team provides clinical services at a variety of outpatient and inpatient clinics in the greater Baton Rouge area.
His former doctoral students have taken positions in academic psychology departments, medical schools, veterans administration and forensic hospitals, and his undergrad RA's have been successful securing masters and doctoral graduate student positions as well as a Fulbright scholarship
Current Research Projects
Alex Cohen is currently collaborating on a project adapting biobehavioral technologies for use in assessing mental state. This project involves an international and multidisciplinary consortium of industry ("Silicon Valley") and academia. Natural biobehavioral data is procured using smart phone apps and is analyzed in real time using "Big Data" analytic methods to measure and predict cognitive, affective and behavioral states in individuals with serious mental illnesses.
He is also part of an international consortium investigating links between disturbances in natural speech, symptoms of mental illness and genomics. A feature of this consortium is the use of computational linguistic and vocal analysis using large biobank data. Advanced machine learning and pattern recognition procedures are being used.
Additionally, he conducts research using "small data" methods to understand how emotion, cognition, motivation and social functions are affected in serious mental illness and those at putative risk for developing them. Emphasized in this research is the use of basic psychological science methods assessing across various levels of "complexity" of the central nervous system - including a range of self-report, biobehavioral and electrophysiological measures and performance measures. Mobile assessment, laboratory and survey methods are emphasized.
