While at the American Dietetic Association, she directed practice based nutrition/dietetic research and managed strategic planning for a member based committee and advisory group.
She earned a PhD and MS from Purdue University in Nutrition Science studying the effect of soy protein/phytoestrogens on calcium and bone metabolism for her dissertation and the effect of magnesium on diabetes for her MS thesis along with earning her RD credentials.
Dr. Spence has published original research and reviews on calcium, dairy, bone health, and weight management. She has served on the United States Department of Agriculture’s review panels for human nutrition and obesity and childhood obesity prevention and participated in several professional organizations.
Dr. Lawrence Appel MD, MPH, FAHA
Dr. Lawrence Appel is the C. David Molina Professor of Medicine, Epidemiology and International Health at Johns Hopkins. He is also the Director of the Welch Center for Prevention, Epidemiology and Clinical Research, a joint program of the Johns Hopkins School of Medicine and the Bloomberg School of Public Health. The focus of Dr. Appel’s investigative career is the conduct of clinical, epidemiologic and translational research pertaining to the prevention of hypertension, cardiovascular disease, and kidney disease through nutrition and lifestyle modification.
To this end, he leads three complementary research programs:
- controlled feeding trials that identify optimal diet (e.g. DASH, DASH-Sodium, OmniHeart, OmniCarb)
- behavioral intervention trials that test novel strategies to accomplish lifestyle modification, often focused on obesity (e.g. PREMIER, Weight Loss Maintenance, and POWER)
- trials and observational studies to understand risk factors for chronic kidney disease progression and its complications (e.g. AASK and CRIC)
He has a keen interest in research methods and has conducted a diverse array of studies, including cohort studies, clinical trials, and meta-analyses. A particularly notable feature of this research is the focus on chronic conditions and diseases that disproportionately afflict minorities and on interventions that have the potential to substantially reduce racial disparities. The site of his research is ProHealth, a community-based clinical research unit that he directs.
Dr. Appel has been actively involved in health care policy. He was a member of the 2005 and 2010 U.S. Dietary Guidelines Scientific Advisory Committees. For the American Heart Association (AHA), he has been a member (and past chair) of its Nutrition Committee for over 10 years. Currently, he is chair of the Lifestyle and Cardiometabolic Health Council of the AHA. He has also served on several Institute of Medicine Committees and chaired the committee that set dietary reference intakes for sodium, potassium and water. He has served on numerous advisory committees for the National Institutes of Health. In 2012, he was elected a member of the Institute of Medicine (IOM). In 2015, he was elected a member of the Association of American Physicians (AAP).
