Genetic risk architecture of neuropsychiatric disorders
The goal of our research group is to better understand the developmental mechanisms and trajectories of childhood neuropsychiatric disorders, from the prenatal period through adolescence. We are keen to leverage large-scale data and statistical and computational methods to facilitate precision psychiatric approaches.
Perinatal Mental Health
We study the interplay of genetic and environmental factors influencing mental health disorders during pregnancy and their impact on child development. Our group strives to integrate cutting-edge computational genomics, epidemiological studies, and statistical genetics approaches to achieve this goal.

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device, biotechnology companies, and other outside entities 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 outside financial relationships.

Below are financial relationships with industry reported by Dr. Mahjani during 2024 and/or 2025. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
