Division of Occupational Medicine

The Division of Occupational and Environmental Medicine is committed to preventing and treating occupational and environmental injury and illness through clinical services, education, and research. The Division’s groundbreaking contributions in these fields has been made possible by our multidisciplinary approach. Find out more about our core components below. 

Clinical Services

The multidisciplinary team of physicians, nurse practitioners, industrial hygienists, and ergonomists provides comprehensive patient-centered services to workers via the Mount Sinai Selikoff Centers for Occupational Health. The Selikoff Centers are the clinical core of the Division and are designated by the CDC/NIOSH as both World Trade Center Health Program and Total Worker Health Clinical Centers of Excellence.

Workplace Injury and Illness Prevention

Mount Sinai Working Healthy is a program that helps employers, unions, and other stakeholders create safer, healthier, and more productive workplaces by integrating health protection and health promotion strategies to prevent occupational injury and illness.


The Occupational Medicine Residency Training Program is an ACGME-accredited two-year combined academic and practicum experience. As a resident in this program, you are exposed to a didactic curriculum, and emphasis is placed on the performance and practice of teaching, clinical and community service, administration, and research. The Division houses the NY/NJ Education Research Center, a NIOSH-supported consortium of academic institutions that provides teaching, training, and research opportunities in occupational health and safety.

Occupational Health Data Management

The World Trade Center Health Program General Responder Cohort Data Center is home to professionals trained in data management, data analysis, biostatistics, epidemiology, and medicine. The Data Center manages and analyzes health-related data for 9/11 responders enrolled in the World Trade Center Health Program. With unparalleled capability in study design, analysis, and data management, our team identifies risk factors and organizational solutions that can prevent illness and injury and support the long-term well-being and productivity of an entire workforce.


One cornerstone of our Division’s work is cutting-edge research related to the prevention, diagnosis, and treatment of occupational illness and injury. Some examples of current research areas include health effects of diesel exposed workers, women’s health in the workplace, neurodevelopmental and neurodegenerative effects of manganese and lead exposure, and WTC attack-related diseases.
