Biography

After studying physics and mathematics at the University of Vienna, Austria, Dr. Dydak received her PhD and postdoctoral training in physics and engineering of Magnetic Resonance Imaging at the Swiss Federal Institute of Technology (ETH) Zürich, Switzerland. Dr. Dydak’s research is focused on the development of Magnetic Resonance Spectroscopy (MRS) techniques for the noninvasive in-vivo assessment of metabolite and neurotransmitter concentrations, and their application to study physiological and pathophysiological mechanisms. A long-term goal of this research is to translate these novel MRS methods into viable clinical diagnostic procedures that aid in disease detection as well as assessment of treatment response. Special emphasis of her work lies on the development of the in vivo detection and quantification of γ-aminobutyric acid (GABA), an inhibitory neurotransmitter, to study manganese-induced parkinsonian neurotoxicity and idiopathic Parkinson Disease. A second focus lies on the development of whole-liver phosphorous (31P) magnetic resonance spectroscopic imaging of the human liver to improve treatment monitoring in liver cancer.

Dr. Dydak holds an adjunct appointment at the Department of Radiology and Imaging Sciences at IU School of Medicine (link to http://imaging.medicine.iu.edu), where part of her research lab is located. She also holds an adjunct appointment at the Department of Biomedical Engineering at IUPUI, and a courtesy appointment with the Department of Speech, Language and Hearing Sciences at Purdue University.
