Occupational Medicine Residency
Occupational and Environmental Medicine Residency/Fellowship Program
The primary goal of the Occupational and Environmental Medicine Residency is to train practicing physicians to be qualified for careers in occupational and environmental medicine in private practice, industry, government, military, or academia.
This two-year program includes completion of the requirements for a Master of Public Health degree, and twelve months of full-time experiential rotations in various aspects of professional practice in the field. Graduates are eligible to apply for board certification in Occupational Medicine by the American Board of Preventive Medicine. The program is accredited by the Accreditation Council on Graduate Medical Education.
The interdisciplinary curriculum is based on both a clinical and public health model for practice. The major focus is on population aggregates rather than individuals and indirect rather than direct care to clients. Graduates are prepared to participate in a multi-disciplinary approach to planning, implementing, managing, and evaluating programs and services for worker health and safety and well being. A mastery of basic clinical skills and significant clinical experience is expected as a prerequisite.

Occupational Medicine Faculty
Brett Perkison, MD, MPH
Brett Perkison, MD, MPH, obtained a B.S. in biology at Texas A&M University. He then obtained a medical degree at the University of Texas Medical Branch in Galveston. He completed residencies in Family Medicine at Baylor College of Medicine followed by a residency in Occupational and Environmental Medicine at the UTHealth School of Public Health in Houston. Dr. Perkison is board certified in both specialties and a Fellow in the American College of Occupational and Environmental Medicine.
Dr. Perkison’s current area of research interest is measuring the effectiveness of worksite health care innovations for employees in the areas of chronic disease management, disease education programs, targeted case management, and home intervention programs. Measured outcomes will include rates of absenteeism, presentism rates, safety incidences and occupational injuries\occupational illnesses. Safety and occupational injuries are more typically measured in order to assess the degrees of workplace safety for an organization. However research suggests that improving the general health of the workplace population will also greatly reduce injury rates. He also maintains a joint appointment at the University of Texas Houston Health Science Center in the Family Medicine department where he provides primary and occupational care. Dr. Perkison's research publications are available at: https://www.ncbi.nlm.nih.gov/myncbi/1pa0ucD38iwAs/bibliography/public/.
