Occupational Medicine Residency

Residency Info

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.

Stipends, Tuition Support, and Benefits

Residents/fellows receive a stipend, adjusted according to post-graduate year level.*

These stipends are competitive with other national residency programs.

In addition to the stipend, tuition and fees are covered by the Residency Program, professional liability coverage, a benefits package, and travel to one professional meeting per year are also provided to each trainee.

* Unless special funds are identified, stipend support is limited to U.S. citizens and permanent residents.


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. A mastery of basic clinical skills and significant clinical experience is expected as a prerequisite.

Admission Requirements

Applicants to the Occupational and Environmental Medicine (OEM) Residency Program must have a minimum of one postgraduate clinical year (PGY-1) in an ACGME -accredited program. The Residency Advisory Committee, however, will give preference to applicants who have completed three or more years of an internal medicine, family practice or emergency medicine residency. Applicants must possess or be eligible to obtain either an unrestricted Texas medical license or a State of Texas In-training Permit prior to commencing the Residency. Application is made through the Electronic Residency Application Service (ERAS) offered by the American Association of Medical Colleges. For more information you may access ERAS online at The applicants documentation is first reviewed by the Program Director, who then forwards acceptable applications to the OEM Residency Advisory Committee. After review of all candidates, residency positions are offered to approved candidates according to a resource-based prioritized list. Selected candidates receive an application form for the MPH degree program at the School of Public Health. Admission to the OEM Residency Program is contingent upon admission to the School of Public Health.

MPH Degree

Master of Public Health Degree

Typically, coursework required for the MPH degree is completed in one calendar year. At least one course in each of the Public Health core disciplines of epidemiology, biostatistics, environmental sciences, management and policy sciences, and behavioral sciences is required. Supplemental courses serve to broaden and enrich the program and are selected through the academic advising process tailored to the individual trainee. Common selections include: Industrial Hygiene, Toxicology, Clinical Occupational Medicine, Field Trips in Occupational Health, and Workplace Safety. Trainees are also able to choose from many electives and independent studies available within the School. To fulfill the requirements for the MPH degree, a practicum and a culminating experience project are also required. During the academic year, progress is monitored by a Master s Advisory Committee that meets with the student at the end of each semester. Opportunities for research projects exist in many areas.


Occupational and Environmental Medicine Practicum

The practicum consists of twelve months of full-time applied practical public health-oriented administrative clinical rotations. These include a minimum of four months of assignments at some of the large industries in the Houston area, four to six months of rotations at various occupational medicine and subspecialty clinics and at least one month in a public health agency. Industrial rotation sites include:

  • Chevron (Houston)
  • ExxonMobil Corporation (Houston, Baytown)
  • Shell Health Services (Pasadena, Houston)
  • The University of Texas MD Anderson Cancer Center (Houston)

Where feasible, these rotations are scheduled through both corporate medical offices as well as plant medical departments. Clinical rotation sites include:

  • Concentra Medical Centers
  • Memorial Hermann - Employee Health
  • Occupational Medicine Care
  • Respiratory Consultants of Houston
  • Texas Medical Center Employee Health Clinic
  • The University of Texas Health Science Center at Houston, Health Services
  • U.S. Healthworks

Opportunities also exist for elective rotations with various specialty clinics and government agencies including, Harris County Public Health & Environmental Services (Houston), OSHA (Washington DC), NIOSH (Cincinnati OH and Morgantown WV), Texas Department of State Health Services (Houston), and NASA Johnson Space Center (Houston). Clinical and elective rotations are typically one to two months in duration. One day each week the trainees convene at the School of Public Health for formal clinical didactic sessions to discuss interesting cases and to participate in research seminars. A reciprocal evaluation system is in place for trainees, rotation sites and faculty preceptors. The monthly Journal Club features presentations by occupational medicine residents/fellows and occupational health doctoral students. Academic and community professionals in the fields of occupational medicine, occupational nursing, industrial hygiene, and epidemiology attend this forum.

The Southwest Center for Occupational and Environmental Health at UTHealth School of Public Health is one of 18 Education and Research Centers in the United States, supported by the National Institute for Occupational Safety and Health (NIOSH). The Center is comprised of academic degree programs in occupational medicine, industrial hygiene, and occupational epidemiology, and supports active continuing education, outreach and pilot project research training programs.

Brett Perkison, M.D.
Brett Perkison, M.D., M.P.H

Brett Perkison, M.D., M.P.H., is originally from Texarkana Texas and 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.
