Following his radiation oncology residency from India, he pursued a neuro-oncology fellowship from Tata Memorial Hospital, India, the largest cancer hospital in Asia. He then completed a two year fellowship in Cyberknife and Stereotactic Ablative Body Radiotherapy from the University of Ottawa.
He also has completed a Master's Degree (MSc) in Clinical Trials from University of London, UK. He also has a Diploma in Computer Applications and a Professional Diploma in Clinical Research (PDCR).

After his fellowship from Ottawa, he served as a staff radiation oncologist at Prince Edward Island Cancer Treatment Centre and was an assistant professor at Dalhousie University, Halifax for 3 years.

Dr Nair has a keen interest in innovative medical research as well as the use of advanced radiation techniques in radiation oncology. As a clinical investigator and a collaborator, he holds numerous peer-reviewed research grants focusing on innovative research in Oncology.

He is a part of the RealizeLab which partakes in research involving Virtual Reality in medicine (
