Welcome to my personal website

SureshRattan-May2015 I am SURESH RATTAN       

I am a scientist researching on the biology of ageing – Biogerontology – and so, I am a biogerontologist.

BIOGERONTOLOGY is also the name of a peer reviewed international journal, published by Springer Publishers, with me as its founder and Editor-in-Chief, since its inception in 2000.

You may have reached this site by choice or by chance; and if you want to know more about my educational background, academic achievements – degrees earned, and awards, honours and other symbols of success including publications, discoveries, ideas, and more – you are welcome to surf the relevant sections as given in the navigating buttons above.

 for a quick summary, you can go to Wikipedia to read a short write up about me, and then come back to this page for details.


What I can do for you:

1. give unique and exciting lectures and workshops on health, ageing, longevity, at all levels of understanding – from school children to “lay-public” to journalists to scientific experts, and incorporating biology, psychology, sociology and more…

A list of my forthcoming and some recent past lectures can be seen by clicking here.  And some of my short videos can be seen by clicking here.

2.  provide consultancy to companies involved in researching and developing practical applications, including cosmetics, cosmeceuticals, nutriceuticals, hormetins; and

3. undertake research supervision/guiding for BSc, MSc, PhD studies and beyond;

4. train you for effective science communication (lecturing, writing research/review/popular articles) for scientists and public; &

5. grant your age care and health care hormetic products a scientific evidence-based  “Certificate of Authentication” as potential hormetins.

I can also guide you get into the field ageing research, thinking and innovation.








Highlights of my ageing research career and ideas

Following are some of the major contributions, for which, I think, I can take some credit:

  • GERONTOGENES:  Coining the term “gerontogenes”  (1984) for any genes involved in ageing, and then modifying it to “virtual gerontogenes”  (1994) to indicate that real gerontogenes do not exist.
  • KINETIN:  Discovering the ageing modulatory effects of cytokinins, kinetin and zeatin on human skin fibroblasts (1986), which are now used in several skin care products worldwide.
  • BIOGERONTOLOGY:  introduced this term for my course on the biology of ageing (1995), and then used it for the journal “Biogerontology” (started in 2000), which since then has become a standard term to refer to the study of ageing at the biological level.
  • ESSENTIAL LIFESPAN: Coining the term “essential lifespan”  (1999) for the duration of life as “required” by evolution in assuring the survival of a species for the continuation of generations.
  • HORMESIS:  Applying and refining the concept of mild stress-induced hormesis in ageing research and interventions (since 1998).
  • HORMETINS AND HORMETICS:  Coining the terms “hormetins” (2005) for conditions that induce hormesis, and “Hormetics” (2011) for the science and study of hormesis.
  • HOMEODYNAMIC SPACE:  Developing the concept of “homeodynamic space” (2002) as an indicator of the survival ability and buffering capacity of dynamic biological systems; and “shrinkage of the homeodynamic space” as the phenotype of ageing.
