Chris W. Tschumi

Dr. Chris W. Tschumi is an Assistant Professor in the Department of Psychology at the University of Texas at El Paso within the College of Liberal Arts. His research focuses on the molecular and neurocircuitry mechanisms underlying motivated behaviors and their dysregulation in neuropsychiatric disorders, particularly substance use disorders and autism spectrum disorder.

The lab employs advanced techniques including:

• Whole-cell patch clamp electrophysiology
• CRISPR-mediated gene editing
• In vivo calcium imaging
• Operant behavior assays

Research investigates how genetic factors associated with substance use disorders and autism influence:

• Dopamine signaling reward pathways
• Social interaction neural mechanisms
• Synaptic plasticity in midbrain circuits
• Neurotensin-mediated neuromodulation

Publications reveal consistent focus on dopamine neuron function, neurotensin signaling, and substance use interactions across preclinical models and electrophysiological analyses. Key subtopics include GABAergic transmission, receptor mechanisms, and neurochemical adaptations.

Dr. Tschumi teaches courses in:

• PSYC 3330: Sensation and Perception
• PSYC 4345: Neurobiology of Social Interaction

Education:

• Ph.D., University of Texas Health Science Center at San Antonio (2019)
