[3] Suresh Rattan has been heading, since its inception in 1984, the Laboratory of Cellular Ageing at the Department of Molecular Biology and Genetics[4] at the Aarhus University in Denmark, where he has become Emeritus since 2020.

He is also the recipient of an Honorary Doctorate from the Russian Academy of Medical Sciences for his "...fruitful research and training in the field of biology of ageing, as well as his outstanding contribution to dissemination of scientific knowledge in basic gerontology...".

The British Society for Research on Ageing (BSRA) has awarded their prestigious Lord Cohen Medal to Suresh Rattan for his continuing contributions to gerontology.

[7] He was also given the Outstanding Career Achievement Award - 2017, by the International Dose Response Society, USA [8] Suresh Rattan has published over 300 research and review articles[9] and about 20 books[2] on the biology of ageing, including those for school children and general public.

Additionally, in the area of ageing modulation, Suresh Rattan is credited with the sole inventorship for discovering the anti-ageing effects of kinetin[13] and zeatin in human skin cells; and these compounds are being used in several skin-care cosmetics throughout the world, for example Valeant product Kinerase.
