- I am currently conducting independent basic science research while simultaneously completing a residency in General Pediatrics at Mount Sinai. My research focuses on understanding the neurobiological basis for resilience, i.e. the brain wiring that gives some individuals the ability to withstand adversity. Currently, my lab is working on a mouse model of social defeat and developing predictive measures of resilience using a combination of behavioral tasks, high resolution confocal microscopy, and resting state fRMI. My ultimate goal is to pioneer "developmental neuroprevention" by creating tools that will enhance resiliency neural networks in children, thereby leading to happier, healthier lives.

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.Dumitriu is not currently required to report Industry relationships.
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.
