Having trained in medicine and public health, his clinical and research interests lie in health promotion through community participation in research aimed at reduction of health inequities. In his role as a primary care physician, he has developed a niche in caring for immigrant and refugee patients, both at Mayo Clinic and in community clinics. His research is focused on assessment of the structural barriers and facilitators to health among vulnerable populations and participatory derivation of local interventions to address these factors. With funding from the NIH and Mayo Clinic, he has led initiatives to improve community and immigrant health with local solutions.
