Research interests
Dr. Nag has been involved in the study of lungs since his days as a graduate student at Memorial. He is currently researching, with the use of an instrument he designed and helped to construct, how and why surfactant, an important chemical complex in the lungs, is negatively impacted by the leaking of blood into this organ. He is in the process of applying for funding to purchase an AFM and a RAMAN microscope for Memorial. These instruments, according to Dr. Nag, are so finely tuned that studying surfactant from a molecular level would be that much more precise.

Dr. Nag spent much of his masters and PhD work focussed on how surfactant in the lungs works. This substance, also known as lung surface active material (SAM), works as a lining on the lungs to prevent them from sticking together when one exhales. In the 1960s, it was found that children born without SAM often died of a disease known as respiratory distress syndrome (RDS). Further studies have led to the creation of artificial surfactant that can be instilled into the child's lungs, thereby allowing them to breathe and survive. For his work in this area, Dr. Nag won a best presentation award at the 39th Canadian Federation of Biological Societies Meeting, held in London, Ontario, in 1996. Following his time at Memorial, he received a three-year post doctoral fellowship from the Canadian Institute of Health Research/ Canadian Lung Association (formerly the Medical Research Council) to train at the University of Western Ontario.

After completing a B.Sc. and an M.Sc. in physiology at a university in Calcutta, Dr. Nag came to Memorial University to complete his masters and PhD in biochemistry. Following post-doctoral studies at Western, and a one-year assistant professorship at Ryerson, Dr. Nag returned to Memorial as an assistant professor of biochemistry in September 2002. He has been awarded a prestigious New Investigator grant for the next five years from the Canadian Institute of Health Research (CIHR).
