PROJECT SUMMARY/ABSTRACT
In the United States, increasing numbers of women are experiencing pregnancy complications such as
preeclampsia, eclampsia, and gestational hypertension that can put their own and their children’s immediate
and long-term health at risk. In particular, these hypertensive disorders of pregnancy are associated with
increased incidence of postnatal cardiovascular disease in women. The link appears to be the placenta, an
organ that both regulates nutrient flow to the developing fetus and influences maternal cardiovascular function.
Nonpersistent endocrine disrupting chemicals (EDCs), including bisphenols found in plastics and phthalates
found in personal care products, have been associated with cardiovascular disease and may also be
associated with placental dysfunction. Over the course of my masters, doctoral, and postdoctoral training, I
have begun to develop a portfolio of published research in both environmental and reproductive epidemiology,
with a particular emphasis on identifying underlying biological mechanisms. My prior education and experience
positions me well to undertake my proposed K99/R00 research project: examining relations among maternal
exposure to nonpersistent EDCs, biomarkers of placental dysfunction, and indicators of maternal
cardiovascular disease both before and after pregnancy. This Pathway to Independence Award will provide the
additional mentorship and expertise I need to transition to faculty and successfully compete for funding as a
principal investigator. My training plan includes formal courses, workshops and seminars, directed readings,
and apprenticeships to develop skills in 1) EDCs, environmental epidemiology, and exposure assessment, 2)
advanced statistical methods, and 3) the intersection between placental and cardiovascular health. In the K99
phase of my research, I will leverage data currently being collected in the New York University (NYU)
Children’s Health and Environment Study (CHES) that includes both prenatal maternal biomarker and
questionnaire data as well as postnatal maternal cardiovascular measures. In the R00 phase, I will incorporate
additional preconception data from the NYU Factors Influencing Reproductive Success and Time to Pregnancy
(FIRST) Study. Specific Aims include 1) examining relations of maternal prenatal urinary phthalate and
bisphenol levels to maternal biomarkers of placental development, and trimester-specific effects of EDCs on
placental size at birth, 2) examining relations of prenatal urinary phthalate and bisphenol levels measured in
three trimesters of pregnancy to maternal clinical cardiovascular risk factors at 1 and 2 years postpartum in
CHES, and 3) assessing relations among maternal preconception phthalate and bisphenol exposure,
preconception cardiovascular risk factors, time to pregnancy, and placental growth and development using
combined CHES and FIRST data. These training and research activities will increase my expertise as an
environmental epidemiologist and prepare me to successfully compete for R01 funding as an independent
investigator with a focus on reproductive and women’s health.
