Welcome to the website for the James Madison University Multiple Chemical Sensitivity (MCS) Research Team. We study the life impacts of living with Multiple Chemical Sensitivity, also referred to as Environmental Illness, Chemical Injury, and Chemical Hypersensitivity. MCS is sometimes associated with Electromagnetic Sensitivity.


Thank you to everyone who participated in our Unmet Medical Needs study and the accompanying interview study. We are currently writing both. We don't have a current data collection, but should in the near future.

Check our current studies page to see what we are doing.
