Grey Matters Group is the brainchild of Dr. Thom and his post-doctoral mentor Dr. Chris Johnson. It is a non-profit (501c3) organization that exists to perform research and development in support of humanitarian aid workers across the globe. We offer several levels of assessment before, during, and after an in-field experience. Our pre-field assessments provide valuable information to the individual about readiness while our during and post-field assessments provide information about risk and resilience factors that promote adaptation during and after stressful circumstances.
