Dr Raghav Sundar obtained his medical degree from the Yong Loo Lin School of Medicine, National University of Singapore, where his academic distinctions earned him a place in the Dean’s List and the Thambipillai Silver Medal. He topped the country in the Internal Medicine specialty examination obtaining the Master of Medicine (Internal Medicine) and the Gordon Arthur Ransome Gold Medal in Internal Medicine. He was Chief Resident and Chief Senior Resident during his training at the National University Hospital. He subsequently completed his Medical Oncology Senior Residency at the National University Cancer Institute, Singapore (NCIS). His clinical interest is in gastrointestinal cancers. His research interest lies in early phase drug development, immunotherapy, epigenetics, biomarker discovery, DNA damage repair, and chemotherapy-induced neuropathy. He was awarded the National Medical Research Council Overseas Fellowship Award to undergo fellowship training at the Drug Development Unit, Royal Marsden Hospital, UK. He won the Conquer Cancer Foundation of ASCO Merit Award for his work on developing novel anticancer therapeutics. He holds several grants and has secured over $1,500,000 in grant funding. He has published in high impact peer-reviewed journals including Cancer Discovery, Annals of Oncology and Clinical Cancer Research and designs clinical trials for novel cancer drugs.
