Toxicology (TOXI)   

Program Title and Classification


Graduate Degree Program

College: Public Health


The Doctoral Program in Toxicology and Environmental Health at the Maryland Institute for Applied Environmental Health (MIAEH) is part of the University of Maryland System-Wide Graduate Program in Toxicology. Our students focus on chemical, biological and/or physical exposures and the related physiological and environmental vulnerabities and susceptibilities. Students will master an essential core of knowledge in toxicology and environmental and occupational health, exposure sciences, risk assessment, epidemiology and biostatistics. The consequences of the built environment and environmental injustice are a critical part of the overall program. Elective courses and rotations with faculty led field studies and laboratories, offer students the background and tools needed to specialize within the broader area of toxicology and applied environmental public health.

Applicants should review faculty interests and establish a dialogue  (email/phone) with one or more faculty before applying. 

MIAEH additionally offers a Masters of Public Health (MPH) Program in Environmental Health Sciences and supports a PhD program in Environmental Epidemiology.

Admissions Information

Applications should be submitted through the Schools of Public Health Application Service, (SOPHAS), at Remember to designate the University of Maryland School of Public Health, College Park (SOPHAS Code 0485) as one of your school choices along with your desired program. SOPHAS will verify submission, and if complete, SOPHAS will inform the University of Maryland Graduate School. The verification process can take 4-6 weeks to complete. We do not accept materials outside of the SOPHAS process. The University of Maryland Graduate School requires a Supplemental Application and a Supplemental Application Fee of $75 for each program. This request will be made by the Graduate School once your SOPHAS information is verified by SOPHAS.
