Short Biography

Dr. Ufuk Olgac joined the Interface Group at the Institute of Physiology in University of Zurich as a post-doctoral researcher in September 2012. His main research interest is in the computational modeling of flow and transport related phenomena in physiology. He was previously a post-doctoral researcher in Koc University in Istanbul, under the guidance of Prof. Dr. Metin Muradoglu, working on computational biofluid dynamics of the respiratory system. Before, he was a research & teaching assistant at the Laboratory of Thermodynamics in Emerging Technologies at ETH Zurich, where he completed his Ph.D under the supervision of Prof. Dr. Dimos Poulikakos. His doctoral research dealt with the modeling of low-density lipoprotein (LDL) transport in human coronary arteries and its association with blood flow characteristics. He completed his masters and bachelors degrees, both in mechanical engineering, at Koc University in Istanbul and Middle East Technical University in Ankara, respectively. Upon completion of his post-doctoral research at the Interface Group, he moved towards the industry.
