    Manish Arora, B.D.S., M.P.H., Ph.D., is the Director of Exposure Biology at the Senator Frank Lautenberg Environmental Health Sciences Laboratory in the Department of Preventive Medicine. Dr. Arora is an environmental epidemiologist and exposure biologist. He graduated with a Ph.D. from the University of Sydney in 2006, and undertook postgraduate fellowship training at the Harvard School of Public Health. Dr. Arora’s research focuses on effects of prenatal and early childhood chemical exposures on life-long health trajectories. He is known for his work on biomarkers that utilize human deciduous and permanent teeth to reconstruct the timing of exposure to various harmful chemicals and essential nutrients. His methods are being applied to the study of outcomes that are national health priorities, including autism and children’s neurodevelopment. Dr. Arora has also undertaken research on the intersection of oral and systemic health with the environment. His work supports shared genetic risk factors between periodontal disease and various cancers (pancreatic, colorectal, and prostate cancers). He has also reported increased risk of periodontal disease and dental caries in those exposed to environmental metal toxicants.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Arora did not report having any of the following types of financial relationships with industry during 2015 and/or 2016: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
