- ASSISTANT PROFESSOR Preventive Medicine
Dr. Horton earned her doctoral degree in Environmental Health Sciences at Mailman School of Public Health, Columbia University. During her doctoral training, she gained expertise in the development and use of biological markers to measure prenatal and early life exposures to environmental toxicants, focusing mainly on residential exposure to pesticides. Subsequently, she completed a postdoctoral fellowship at the Sergievsky Center for the Epidemiologic Study of Neurologic Diseases. The focus of this postdoc was to explore the use of brain imaging to investigate the impact of prenatal exposure to pesticides and secondhand smoke on neuropsychological and behavioral function throughout childhood. Dr. Horton was recently awarded an NIH career transition award and accepted a position as an Assistant Professor of Preventive Medicine at Icahn School of Medicine at Mount Sinai. Her current work combines her experience with biomarker development and neuroimaging to understand the mechanisms of neurodevelopmental toxicity following exposure to chemical mixtures.

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. Horton did not report having any of the following types of financial relationships with industry during 2014 and/or 2015: 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.
