Academic and Research: I consider myself a Physician-scientist. Over the years,  I  have played a  pivotal role in transforming the Nuclear  Medicine department at AIIMS  into a vibrant diagnostic and therapeutic hub with a strong emphasis on research and innovation,  extending beyond conventional imaging services.  With more than 500 publications, over 11,000 citations,  and an h-index of 54, I have established myself as a leading figure in the field. I have introduced innovative interventions using a range of radioactive molecules to treat various clinical conditions,  improving patient care while remaining cost-conscious. My research work is primarily focused on thyroid cancer and neuroendocrine tumors. My research  in the last two decades has been instrumental in formulating management guidelines for thyroid cancer, with multiple randomized·  controlled trials guiding the dosage of radio-active   Iodine and  surgical planning.   The extensive longitudinal database established in my department has significantly contributed to enhancing the care of thyroid cancer and is cited by several international management guidelines.

Awards and Honours: In the management of neuroendocrine tumors, in recognition of my work on NET SNMMI, USA, as a featured article on the cover page of the "JNMMI" Feb 2023 issue. My contributions were further acknowledged with the Dr. Henry Wagner Jr. award as the International Best Researcher consecutively in SNMMI Annual meetings in the years 2021 and 2022. I was invited to deliver a one-hour webinar by SNMMI, USA for the members in 2023.

Other Contributions: I am a Fellow of all three  Science  Academies (viz.,  namely the Indian Academy of Sciences,  National  Academy of Sciences,  and  Indian  National  Science  Academy),  in addition to being a Fellow of the National  Academy of Medical Sciences.
