RESEARCH INTERESTS:

Dr. Nelson's research is aimed at understanding the genetic and physiological basis for nutritional and pharmacologic interventions that extend rodent longevity. Most recently, his laboratory discovered dramatic genetic variation in the lifespan response to dietary restriction, including a life-shortening effect in some genotypes.  These findings provide a new way of identifying the genes and probing the mechanisms whereby dietary restriction and other interventions affect aging. For example, his group found that maintenance not reduction of adiposity was a strong correlate of lifespan extension, whereas reduction in adiposity was a risk factor for life shortening by dietary restriction.  His research also focuses on the role of endocrine systems in aging, with a particular focus on the role of hyperadrenocorticism and insulin signaling in the life-extending effect of dietary restriction.
