I received my medical education and my MD degree from the University of Istanbul Medical School in Istanbul, Turkey. Subsequently, I received specialty training in Obstetrics and Gynecology in Istanbul. Afterwards, I completed my fellowship training on Fetal Medicine under the supervision of Prof. Kypros Nicolaides in Fetal Medicine at the Harris Birthright Research Center, King's College Hospital, UK. Following my fellowship, I joined the Division of Maternal and Fetal Medicine at Yale University.
Thereafter, I joined the University of Maryland School of Medicine, Department of Obstetrics, Gynecology and Reproductive Sciences, Maternal Fetal Medicine working as the Director of the Fetal Heart Program. My clinical interests include prenatal diagnosis of fetal abnormalities and cardiac defects. I have extensive experience on the diagnosis of fetal heart defects using 3 and 4 dimensional ultrasound methods. Accordingly, I have developed a new 4 dimensional ultrasound method to diagnose fetal heart defects during the first trimester of the pregnancy.

I have broad background and experience on fetal ultrasound imaging of the fetal heart. I have also extensive training and hands-on experience on use of 3-4 dimensional ultrasound since 2002. I described a standardized technique to demonstrate structural fetal heart defects at first trimester when the fetal heart size is less than 10 mm, using 3-4 dimensional ultrasound, spatio-temporal image correlation and tomographic ultrasound imaging.
In the light of these experiences, I have clinical research interest in diagnosing congenital heart defects starting from 12 weeks of gestation by using advanced ultrasound image modalities. I have special interests on Diabetic mothers and effect of the diabetes in the heart development. And currently I have been working on to develop miRNA profiles for specific congenital heart defects by using maternal blood at the time of first trimester scan. My basic science research interests are application of new imaging modalities ( 17.6 T MRI) in diabetic mice model to describe cardiac defects and I also work on identifying differences in cardiac structure and function between hypoxic and normoxic pregnant guinea pig model.
Prenatal diagnosis - Sonologist at the Center for Advanced Fetal Care with special expertise in fetal echocardiography, first trimester high-resolution ultrasound.and 3-D and 4-D ultrasound.
First trimester fetal echocardiography – Developed a screening method for congenital cardiac abnormalities using 4-D ultrasound tehniques.
Fetal Cardiology Program – Developed a Fetal Cardiac Program which made the Center for Advance Fetal Care at the University of Maryland a primary diagnostic and referral center for women at high risk for fetal cardiac abnormalities.
Since 2006 at the University of Maryland, in addition to teaching and mentoring students, I have been developing a Fetal Cardiology Program. This Program represents a critical stage along the way to lifelong preventive and interventional health care. Fetal cardiac health -- or dysfunction – results from the complex interaction of genetics, environment, and maternal health.
As our understanding of these factors grows, so should our ability to recognize and manage fetal abnormalities. The Center aims to perform the earliest possible echocardiographic screening, with the goal of diagnosing heart problems as early as the 12th week of gestation, during the first trimester screening. This information allows for early treatment, where feasible, and for parents to make well-informed medical decisions at critical times.

Title: Fetal cardiac biomarkers of congenital heart disease in maternal serum.
The goals are to develop a biomarker assay using small RNA sequencing for detection of microRNAs in maternal serum and in an hypoxic guinea pig animal model.
