Folate, vitamin B12, and one-carbon metabolism; homocysteine and methionine metabolism and relationship to cardiovascular disease risk; nutrient and hormonal regulation of gene expression; chemistry of methyltransferases.
Dr. Garrow's research focuses on how nutrient and hereditary factors interact to increase cardiovascular disease risk. His specific focus is on how these factors influence blood homocysteine levels. Homocysteine is derived from the essential amino acid methionine and high blood levels of homocysteine are known to be a risk factor for cardiovascular disease. Ongoing research includes how diet influences liver metabolism which, in turn, affects blood homocysteine levels. Dr. Garrow's research is funded by the National Institutes of Health and the American Heart Association.

Dr. Tim Garrow received a B.S. in Nutrition Science (1986) and a M.S. in Nutrition (1988) from the University of California at Davis. Following his formal training in nutrition, he continued his education at the University of California at Berkeley where he received a Ph.D. in Biochemistry (1992). Dr. Garrow also obtained postdoctoral training on the Berkeley campus. In January of 1994 Dr. Garrow joined the University of Illinois faculty. Dr. Garrow contributes to the teaching mission of the Department of Food Science and Human Nutrition and the Division of Nutritional Sciences, at both the undergraduate and graduate levels.
