The Department of Physiology and this week's host, Dr. Radhakrishna (RK) Rao, are pleased to welcome:
ANDREW J HOISINGTON, PhD, PE, LtCol (Ret)
Assistant Professor, Physical Medicine and Rehabilitation, University of Colorado Anschutz
Co-Lead of Body, Brain, Biome, and Behavior Laboratory for Health (B4 Health)
Supervisory Health Scientist, Rocky Mountain MIRECC for Suicide Prevention, Department of Veteran Affairs
Adjunct Associate Professor, Engineering Management, Air Force Institute of Technology
Dr. Hoisington will present his seminar titled "Biological Mechanism in the Gut-Brain Axis Connected to Psychological Health"
TODAY, OCTOBER 16
from 3:30 - 5:00 pm in the
Cancer Research Building Auditorium
Refreshments will be provided.
SUMMARY:
Over the past decade, growing research has explored the gut-brain axis and its role in various conditions, including psychological health. While intriguing findings have emerged, definitive biological mechanisms linking the gut-brain axis to mental health remains elusive. One proposed mechanism involves chronic immune system dysregulation or alterations in the gut microbiome, leading to impaired gut barrier function and disrupted metabolic pathways-both of which may contribute to adverse psychological outcomes. This presentation will highlight our retrospective, observational, and interventional studies aimed at elucidating these mechanisms, with the ultimate goal of informing future clinical trials and identifying both pharmacological and non-pharmacological treatment targets for this living with or at risk of negative psychological conditions.
BRIEF BIO:
Dr. Hoisington is currently an Assistant Professor at University of Colorado Anschutz, Department of Physical Medicine and Rehabilitation. He co-leads the Brain, Body, Biome, and Behavior Health Laboratory (B4 Health) and is the Associate Director of the Military and Veterans Consortium for Research and Education (MVM-CoRE). Dr. Hoisington is a supervisory health scientist and leads a biological laboratory in the Eastern Colorado Health Care System, within the Department of Veteran Affairs. He retired after 21 years in the Air Force and during his time in service, he taught nine years at the United States Air Force Academy and at the Air Force Institute of Technology. Dr. Hoisington's overall research interest includes the intersection of human microbiome and mental health, connections between microbiome of the built environment and mental health and associations between the built environment and mental health outcomes. He has been using molecular approaches to investigate human related biological targets in mental health for over a dozen years.
