His motto: "I strongly feel the need for the free flow of medical information in my area of specialisation. With chronic kidney disease (CKD) acquiring an epidemic proportion and diabetes being the most common cause of CKD, it is critical to educate the community in India, about this problem and what can be done to alleviate its onset".
