About the Program Dr.

Venkat Bhat’s research program, affiliated with the Interventional Psychiatry Division at The Royal, is currently looking for a Research Assistant II.

The Interventional Psychiatry Division offers novel psychopharmacological (. IV ketamine/other anesthetic agents), neurostimulation (. rTMS, emerging neurostimulation modalities) and digital therapeutic (mobile-based monitoring and interventions) interventions for Mood and other Disorders.

The interdisciplinary program offers emerging and procedural interventions for psychiatric disorders; the research program aims to understand treatment-response with these emerging interventions.

In addition to Dr.

Bhat, the Research Assistant II will have the opportunity to work with leading researchers in psychiatry, anesthesia, imaging, informatics and biomedical engineering.

This position will focus on psychiatric clinical trials and digital mental health/artificial intelligence.
