Research Goals

Dr. Venkatesan has spent her entire career focused on the epidemiology, clinical presentation, diagnosis, and treatment of cyclic vomiting syndrome and a similar condition, cannabinoid hyperemesis syndrome. Her translational work involves the intersection of the endocannabinoid system with CVS, and she has elucidated endocannabinoid signaling in CVS as well as genetic polymorphisms underlying the condition. She has several key publications and was the lead author on the first-ever guidelines on the management of CVS. She is also co-editor on the first book on cyclic vomiting and cannabinoid hyperemesis and has authored several book chapters in this field.
She is an invited speaker to multiple national and international meetings in her field. She also collaborates closely with the Cyclic Vomiting Syndrome Association (CVSA), a non-profit organization for which she serves as Chief Medical Advisor. She recently started a CVS fellowship, the first of its kind in the world and is committed to understanding the pathophysiology and developing better management options for CVS. She also believes in providing holistic care to her patients and has used complementary techniques such as Heartfulness meditation to improve patient care outcomes.
On a personal note, she is a long-term meditator and a certified Heartfulness meditation instructor. She is also an avid gardener and loves to travel with her family and friends.
