Research interests

I have been interested in studying adverse events related to cancer and its therapy, complications associated with central venous catheters, and survival outcomes. To advance research and knowledge in the same, I am actively engaged in collaboration with basic and translational researchers in pharmacy, pharmacology, gastroenterology, immunology, cancer biology, mathematics and bioinformatics, and epidemiology amongst others to find innovative ways of improving the care of pediatric hematology oncology patients. I attempt to focus on using advanced technologies to improve care and outcome of children with cancer. I am fortunate to have an expanding research program with several students and trainees at all levels of training from undergraduate to postdoctoral and well as medical students and residents. 

I am also interested in studying thrombosis in high risk pediatric populations such as oncology, cardiology, intensive care and neonatology.

Selected awards and honours

  • Early Career Faculty Research Award, Department of Pediatrics (June 2022)
  • Hind Rattan Award (April 2022) - The Hind Rattan, translated into English as 'Jewel of India', is the highest Indian diasporic award granted annually to non-resident Indian or persons of Indian origin (NRI) in recognition of their outstanding services, achievements, and contributions in their respective fields by the NRI welfare society of India, registered with the Government of India. Annually, approximately 25 to 30 members of worldwide Indian Diaspora (global persons of Indian origin and non-resident Indian) from all fields of work are chosen for the award. It is estimated that the Indian Diaspora includes >40 million people. The award is given at the yearly “International Congress for Non-resident Indians” typically held on January 26 (India’s republic day) since 1982. The award ceremony is attended by senior members of the Government of India and of the Supreme Court of India. The 41st congress was held on April 14, 2022 (India’s Victory Day) due to the omicron pandemic wave.I am very fortunate to be among the handful of Canadians bestowed with this prestigious award for my contributions in my fields of interest including Medicine.
