His lab leverages circuit neuroscience, high throughput neuroanatomical and spatial transcriptomic tools, and evolutionary biology to identify the fundamental principles that underlie the structure of the vertebrate brain and its control of behavior.

Project: Identifying epigenomics and connectomics of protracted opioid withdrawal and relapse using cellular barcoding: The chronic cycle of withdrawal and relapse is a major barrier to the treatment of opioid addiction, and few studies have investigated the interaction of changes in gene expression, epigenetics, and circuit connectivity after opioid exposure and withdrawal. Dr. Kebschull’s project will use his recently-developed class of brain mapping tools to simultaneously track changes in all three of these modalities at an unprecedented multi-omic resolution in rodents. By examining these changes, this project aims to understand the long-term circuit changes induced by opioid withdrawal and relapse, and seeks to identify conserved changes that may be candidate targets for treating addiction.
