BIOGRAPHY:
Serge Ahmed is a scientist who specializes in addiction research
in Bordeaux, France. He is a tenure research officer
at the French National Research Council since 1999, and has
been conducting experimental research on addiction since the
early 90s. His PhD thesis was directed on the environmental
modulation of sensitization, a long-lasting alteration in the
brain reward system that can be induced both by repeated
use of drugs of abuse and palatable food. From 1996 to 2000,
he served as a postdoctoral fellow at the Neuropharmacology
Department, The Scripps Research Institute, La Jolla (USA).
There, he developed a unique animal model of the transition
from cocaine use to addiction. This model is now used
in many different laboratories across the world to elucidate
cocaine addiction-related molecular, cellular and behavioral
alterations. Very recently, Serge Ahmed and his PhD students
serendipitously discovered that the taste of sweetness is much
more rewarding than intravenous cocaine and heroin, even in
drug-sensitized animals with a long history of drug self-administration.
Currently, his research work focuses on the relative
addictive potential of sweet beverages.
Serge Ahmed has published several dozen articles, including several the peer-reviewed scientific journals Science and Nature. Serge Ahmed was awarded the Vocation Prize from the Foundation Marcel Bleustein-Blanchet and is a recipient of a young research grant from the French National Agency. Serge Ahmed lives in Bordeaux, France, with his wife.
PERSONAL STATEMENT:
The reason my research focuses on addiction is I want to understand how an initial reward-seeking activity eventually becomes deleterious both to the individual and to the community and how, despite eventually becoming aware of these harmful consequences, both the individual and the community often fail to take appropriate actions to successfully prevent them.
I believe that more financial funding is needed to support comparative research on food addiction and drug addiction. When society finally discovers that refined sugar is just another white powder, along with pure cocaine, it will change its mind and attitude toward refined food addiction.
