Global, Environmental, and Occupational Health

Our Department's Mission

The department of Global, Environment and Occupational Health's (GEOH) mission is to promote and protect human health in the diverse communities across Maryland, the nation and the world through discovery, education, and innovative application of knowledge in the fields of global, environmental, and occupational health.

GEOH is 1!

The Department of Global, Environmental, and Occupational Health (GEOH) is marking our 1 Year Anniversary!

Leena Malayil, Rihanna Murray in the Water Lab

In just ONE year, we have:

  • welcomed over 45 students to our new Global Health and ENSP: Environmental Justice majors
  • trained local contractors (through our WOW Lab) to construct rainwater harvesting and treatment systems for small and urban farms
  • expanded our global impact by supporting low- and middle-income countries (e.g., Nepal, Tanzania, Cameroon) in addressing the health effects of climate change
  • published research on the public health implications of avian influenza emergence in cats and the impacts of extreme heat and drought on human health
  • celebrated the very first UMD Distinguished University Professor (UMD’s highest honor) for the School of Public Health, our very own Dr. Don Milton, and welcomed our new Clark Leadership Chair in Global Health, Dr. Heather Wipfli

Why I Chose Maryland

“The professors were truly invested in the students and their success across the SPH. The mentorship I received made a big difference for me. I continue to engage with my professors and work with several of them.”
