Research Overview

Dr. Turk's research interests are primarily focused on Magnetic Resonance Imaging (MRI). During her MSc and PhD studies, she worked on analysis of the safety of gradient magnetic fields encountered during MRI examination for patients with active implants and also on B1 field mapping techniques. Additionally she developed a new technique using B1 gradients instead of B0 gradients in order to detect shear waves at higher frequencies. In 2013 she joined the Madrid-MIT M+Vision consortium as a postdoctoral fellow and proposed a project titled “Assessment of placental function in growth restricted pregnancies by means of MRI” with her colleagues. She was responsible in the study design, data processing and motion mitigation. Since she joined FNNDSC, she has been working on the assessment of placental function with a growing interest on fetal response to the placental well-being and also fetal MRI safety.

Research Background

Esra Abaci Turk completed her BS degree in the Department of Electrical and Electronics Engineering at Middle East Technical University, Turkey in 2006. She received a full scholarship from The Scientific and Technological Research Council of Turkey for her M.Sc. studies in Bilkent University, Turkey. She received her PhD degree in the Department of Electrical Engineering at Bilkent University, Turkey in June 2013 with an expertise in MRI physics. In July 2013, she joined the Madrid-MIT M+Vision consortium as a postdoctoral fellow and with her colleagues proposed a project on placental imaging under the supervision of Dr. Ellen Grant in early 2014 and funded by Consejeria de Educacion, Juventud y Deporte de la Comunidad de Madrid (Spain). In 2015, Dr. Abaci Turk joined FNNDSC as a research fellow.
