MCS & Toxicant-Induced Loss of Tolerance (TILT): Shahir Masri

The Chemical Sensitivity Podcast

In this episode, Aaron speaks with Dr. Shahir Masri.

Dr. Shahir is a member of the Hoffman TILT Program at the University of Texas Health Science Centre in San Antonio. It is an organization that conducts critical research, education, and outreach about Multiple Chemical Sensitivity and Toxic Induced Loss of Tolerance or TILT.
Dr. Masri is also an assistant specialist in air pollution exposure assessment and epidemiology at the University of California, Irvine. He teaches courses on environmental health and pollution at Chapman University in Orange, California and National University in San Diego, California.

Dr. Masri holds a Doctorate in Science from the Department of Environmental Health at the Harvard School of Public Health.
In this conversation, Dr. Masri talks about how environmental scientists understand MCS, why so many people with the illness struggle to get a medical diagnosis, and how the condition is likely to continue to affect millions of people in the coming years.
Thank you to Dr. Masri for taking the time to speak on the podcast. I hope you find the insights he shares are helpful and interesting.
