• Lecturer, Microbiology, Immunology, and Molecular Genetics
  • Lecturer, Undergraduate Education Initiatives — UCLA Cluster Program


Artin Soroosh received his Ph.D. in Molecular, Cellular, and Integrative Physiology from UCLA. Prior to that, he earned an M.S. in Medical Physiology from Case Western Reserve University. At the Cleveland Clinic (2012-2016) and UCLA (2016-2021), Dr. Soroosh studied the pathogenesis of Inflammatory Bowel Disease, using cell culture, animal models, and patient tissue to uncover the molecular mechanisms behind Crohn’s Disease and Ulcerative Colitis. After earning his Ph.D. in 2021, he transitioned to a career teaching full-time. 

Artin is a lecturer for the Frontiers in Human Aging Cluster course. He also teaches Scientific Analysis and Communication (180A/B) and Introductory Microbiology (101) in MIMG.
