Research summary
AI-generated

Jacek Kołacz studies how the body's autonomic nervous system (the automatic control of functions like heart rate and digestion) relates to mental and physical health. His work examines links between stress, trauma, and bodily symptoms across conditions such as chronic pain, gastrointestinal disorders, diabetes distress, and childhood adversity, often using measures of vagal (parasympathetic) activity and body perception. Several projects also test interventions like neurostimulation and therapy for these conditions.

Collaborators per year
Distinct co-authors at Indiana University each year — a rough indication of whether the group around this researcher has been growing or contracting. An estimate from co-authorship, not a roster: collaborators are not necessarily lab members, and recent years can be under-counted while indexing catches up.
