He is keen to continue to develop the society to enable existing and new members to hear about a wide variety of topical issues and exciting innovations from experts in their fields. 


  • Cardiovascular laboratory-based research into the ageing process of arteries
  • Epidemiology research into hypertension and cardiovascular risk factors
  • Hospital-based research focusing on the use of probiotics in the prevention of hospital acquired infections in the elderly
  • Research focusing on adverse drug events in the elderly
  • Study of biomarkers in the development of Frailty. 


Chakravarthi is particularly interested in developing young people's interest in elderly care and geriatric research. He wants them to see the extent to which research can make a significant difference to this area of medicine. He aims to illustrate how important it is to focus on improving the quality of people's lives rather than just prolonging them. He is also developing various techniques to enable safe bedside teaching to medical students in the current pandemic.
