Wistar’s expertise has traditionally been in the study of cancer biology and immunology — very broad and complex fields that entail multidisciplinary approaches and investigations.
It so happened that David Kritchevsky, Ph.D., an eminent biochemist and expert in human nutrition, worked at Wistar for five decades starting in 1957, generating a vast amount of scientific knowledge on the role of lipids in atherosclerosis, or fat deposits in blood vessels, and prompting early work on the effect of diet on the risk of cancer.
