Welcome to my personal website



I am a scientist – a biogerontologist – addressing the issues of the biology of life and death, ageing, old age, healthy ageing, healthspan, immortality and beyond…

As a multi-dimensional scientist, I can do the following for you:

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

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

3. provide research suggestions/guidance 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  “Certificate of Authentication” for your age-care and health-care hormetic products as scientific evidence-based potential hormetins.

(details of each of the above activities can be found on the specific pages mentioned on the menu above)

BIOGERONTOLOGY is also the title of a peer reviewed international journal, published by Springer-Nature Publishers, with me as its founder and Editor-in-Chief, since its inception in 2000. This journal is a premier journal of ageing research and interventions; and we also celebrate the memories of biogerontologists…


Highlights of my ageing research career and ideas

Following are some of my major contributions, for which, I think, I can happily 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.
