Marcela Perez, M.Sc (Chair, 2014-2015)Marcela Perez

Centro Médico Nacional Siglo XXI Instituto Mexicano del Seguro Social

Dr. Perez is the Program Coordinator in the Clinical Research Training Center of the Mexican Institute of Social Security. Her research interest centers on investigating energy expenditure in obese pregnant women, the role of dietary and physical activity patterns impact on Obesity, Metabolic Syndrome and its components in children and adults. During her Master's degree program she studied the effect of very short, short, medium and long bouts of moderate to vigorous physical activity on adiposity in school age children. Contrary to what physical activity guidelines recommend, which is performing two bouts of 15 minutes each, her work showed that bouts lasting 10 minutes are associated with lower adiposity.

In her Doctoral program, she is currently working on a study looking at differences in dietary patterns associated with Metabolic Syndrome in normal weight, overweight and obese subjects.
