- My research focuses on understanding the neurobiological basis for resilience. In particular, I am interested in how the brains of resilient individuals are wired with the ability to withstand adversity. Currently, we are working on a mouse model involving social defeat, and we are trying to develop predictive measures of resilience using a combination of behavioral tasks, high resolution confocal microscopy of dendritic spines, and resting state fRMI.
Ultimately, I am interested in developing tools that will enhance the neural networks for resilience in children, with the ultimate goal of contributing to the promotion of 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 at http://icahn.mssm.edu/about-us/services-and-resources/faculty-resources/handbooks-and-policies/faculty-handbook. Patients may wish to ask their physician about the activities they perform for companies.
