My research focuses on the role of vitamins B6 and D in reproductive health. My laboratory measures blood levels of vitamins, minerals and other factors that influence various aspects of women’s health and reproductive function. Recently, Dr. Elizabeth Bertone-Johnson (Epidemiology) and I completed a study of nearly 300 young women in the Amherst area to explore the relationship between micronutrient status—including vitamin D—and premenstrual syndrome (PMS). I am also collaborating with researchers at the UMass Medical Center in Worcester to assess vitamin status and birth outcome in low-income pregnant women in central Massachusetts. By assessing maternal dietary intake and micronutrient status in pregnancy, we hope to identify factors that impact both maternal and infant health and that are easily addressed through nutrition interventions. I am also working with UMass Worcester to address lifestyle factors that could ameliorate the symptoms of polycystic ovary syndrome (PCOS). My interest in vitamin nutrition and health also has an international component. I am collaborating with infectious disease researchers at Harvard to study the role of vitamin D status in transmission of tuberculosis in Lima, Peru, and my graduate students and I have recently completed analyses of the micronutrient status of reproductive-age Bangladeshi women.
