Dr. Lewis received his medical degree from the University of Texas Health Science Center at Houston. He then completed clinical training in psychiatry and child and adolescent psychiatry at the Mayo School of Graduate Medical Education, followed by a two-year clinical research fellowship. Dr. Lewis previously held positions as Assistant Professor of Psychiatry and Research Associate at the Mayo Clinic College of Medicine and Science. He joined the University of Minnesota Medical School faculty in 2019.

Research Summary/Interests

Dr. Lewis’ research focuses on the neurobiological correlates of suicidal behavior in adolescents with mood disorders, with the aims of improving risk assessment and identifying novel treatment approaches. His previous work has found impaired cortical inhibition, measured by transcranial magnetic stimulation (TMS), and alterations in excitatory neurotransmitter levels, measured by magnetic resonance spectroscopy, in youth with suicidal behavior. Dr. Lewis is also involved in ongoing projects utilizing noninvasive brain stimulation, including repetitive TMS, theta burst stimulation, and transcranial direct current stimulation (tDCS), as treatment interventions for children and adolescents with depression. 

Research Funding Grants

Dr. Lewis is the Alan G. Ross Memorial Investigator and recipient of a NARSAD Young Investigator Grant from the Brain & Behavior Research Foundation, which supports his ongoing research on state-dependent impairment in cortical inhibition and network connectivity in adolescents with suicidal behavior.
