Nimali Jayasinghe

Nimali Jayasinghe, PhD is an assistant professor of psychology within the department of psychiatry.

She has expertise in clinical intervention and research that focuses on helping people cope with and access quality care to address the emotional impact of traumatic stress, negative life events, and chronic life stress. She has a particular interest in working with older adults on these issues. Dr. Jayasinghe completed her undergraduate degree at Princeton University in New Jersey. She received a doctoral degree in clinical psychology from the New School for Social Research in New York. Dr. Jayasinghe has been working at Weill Cornell Medical College since 2002. She completed a postdoctoral fellowship in clinical psychology at the Program for Anxiety and Traumatic Stress Studies of Weill Cornell Medical College. Dr. Jayasinghe later supplemented her training through an NIH-funded fellowship in geriatric mental health services research.

Dr. Jayasinghe is a New York State licensed clinical psychologist. Some of the diverse groups with whom she has worked include medically ill older adults, men and women from the military, and disaster relief workers. As a clinician, she works with individuals and their spouses/significant others to optimize recovery and adjustment after trauma, negative life events, or chronic stress. She specializes in treating posttraumatic stress disorder, generalized anxiety, specific phobias (such as fear of flying), social anxiety as well as related conditions such as depression or adjustment disorder. She takes a cognitive-behavioral approach to treatment that combines education, building relaxation skills that can be used to reduce tension, teaching techniques to promote adaptive thinking, and exposure (which involves gradual and systematic approach of feared situations). This approach is collaborative, tailored to the individual needs of each person, and evidence-based.
