Research Focus

My research focuses on reproductive and perinatal epidemiology and women's health, particularly the impact of complex exposures on the health of women and children. For example, babies conceived after fertility treatment may have adverse outcomes not only from the treatment itself, but also due to the conditions that reduce fertility. A better understanding of complex conditions will lead to improving clinical decisions and potentially opening avenues for prevention. I am also interested in the impact of a mother's age when she gives birth to a daughter and the latter's reproductive health. Part of my work is methodological, related to addressing selection bias and its implications for studies (e.g., we often can only observe outcomes among women who conceive, pregnancies that survive to detection, or babies who are born alive). I collaborate with Dr. Lucy Gilbert on a study aimed at developing a test to diagnose ovarian and endometrial cancer early.
