Jacek Kolacz, Ph.D.

Postdoctoral Research Fellow

Dr. Jacek Kolacz is a developmental neuropsychologist who studies how life experiences shape biological systems, psychological well-being, and physical health over time. His work at the Trauma Research Center at the Kinsey Institute examines biobehavioral pathways that are sensitive to disruption by sexual violence, their effects on mental and physical health, and their influence on relationships and social interactions. This research will be used to identify factors that confer risk and resilience for sexual trauma survivors and inform new clinical intervention strategies.

Kolacz’s research applies methods for analyzing vocal acoustic features, neural regulation of the heart, statistical modeling for examining complex longitudinal data, and psychometric assessment of survey instruments. His methodological efforts at Kinsey involve the development of novel online data collection tools that will allow remote psychophysiological assessment.
