Additional Information
Dr. Griggs is an Assistant Professor at the Frances Payne Bolton School of Nursing at Case Western Reserve University. She is a sleep and circadian scientist studying the role of the sleep and circadian system in glucoregulation among young adults with type 1 diabetes. She is developing a cognitive-behavioral sleep self-management intervention to promote multiple sleep health dimensions and improve glycemic targets (SLEEPT1). Her work has been funded by the National Institutes of Health/National Institute of Nursing Research (K99NR018886/R00NR018886), American Academy of Sleep Medicine (220-BS-19), and Sigma Theta Tau International.

Dr. Alice H. Lichtenstein is Senior Scientist and Director of the Cardiovascular Nutrition Team at the HNRCA. Her research focuses on assessing the interplay between diet and cardiovascular disease risk factors. Past and current work includes addressing issues related to trans fatty acids, soy protein and isoflavones, sterol/stanol esters, novel vegetable oils differing in fatty acid profile and glycemic index, primarily in postmenopausal females and older males. Additional work is focused on population-based studies to assess the relationship between nutrient biomarkers and cardiovascular disease risk, and application of systematic review methodology to the field of nutrition. Dr. Lichtenstein is the Stanley N. Gershoff Professor of Nutrition Science and Policy at the Friedman School of Nutrition Science and Policy and holds appointments as Professor in the Institute for Clinical Research and Health Policy Studies at Tufts Medical Center, Professor of Medicine at Tufts University School of Medicine, and Professor in the Department of Public Health and Family Medicine at Tufts University School of Medicine. She was awarded an honorary doctoral degree from the faculty of medicine at the University of Eastern Finland. Dr. Lichtenstein currently serves as Executive Editor of the Tufts Health and Nutrition Letter and Associate Editor of Journal of Lipid Research. She was given the Supelco Research Award by the American Oil Chemist Society and an Honorary Lifetime Membership Award in recognition of unusual expertise and contributions to clinical lipidology by the National Lipid Association. She is a Fellow of the American Society for Nutrition and American Heart Association. Dr. Lichtenstein is a member of numerous professional affiliations, including the Food and Nutrition Board for the National Academies of Science, Engineering and Medicine, and was Vice-chair of the 2015 Dietary Guidelines Advisory Committee for the USDA and U.S. Department of Health and Human Services and Vice-chair of the NHLBI Adult Treatment Panel. She was awarded the Alumni Award of Merit from the Harvard T.H. Chan School of Public Health in 2018.
