Fetal development and growth are still poorly understood. The impact of the placenta on early fetal heart development and how the placenta influences fetal growth are two of the most important questions facing Obstetricians and patients. My research focuses on understanding the impact of placental development on the subsequent development of congenital heart disease and how similar placental changes can influence fetal growth.

Research in Brief
Pelvic floor imaging and evaluation of the causality of pelvic floor prolapse: In collaboration with Dr. Pam Moalli and her lab, I have investigating the imaging characteristics of pelvic organ prolapse as it pertains to adverse pregnancy outcome. My unique research focuses on evaluating the real time dynamic function of the pelvic floor and the levator ani muscle group using continuous ultrasound imaging and elastography and shear wave elastography in the assessment of function and structure of the pelvic floor.
Patterns of Fetal Growth and Assessment of New methods of Fetal growth Assessment:. My work on fetal growth has centered around assessing the influence of maternal characteristics on fetal growth and how newer methods of mathematical modeling and use of 3-dimensional imaging can improve prediction of fetal size.
Placental and Fetal Associations with Congenital Heart Disease (CHD): In collaboration with Pediatric cardiology of Children’s hospital, I have been investigating the clinical and ultrasound characteristics of mothers and their fetuses with CDH and investigating placental immunohistochemical expression of multiple angiogenic factors in patients with and without CHD.
