Bestoun S. Ahmed, starts working as a Senior Lecturer at ������ý on January 14th, 2019. He obtained his BSc in Electrical and Electronic Engineering from the University of Salahaddin-Erbil in 2004, his MSc degree from University Putra Malaysia (UPM) in 2009, and his Ph.D. from University Sains Malaysia (USM), Software Engineering, in 2012. He worked as a research fellow at the Software Engineering Research Group at the Universiti Sains Malaysia (USM). His next engagement was as a senior lecturer at Salahaddin University, where he was promoted to Associate professor later in 2015. He completed his postdoctoral research position in the Swiss AI lab at IDSIA (Istituto di Molle di Studi s Intelliigenziale), Lugano, Switzerland, in 2015. He also worked as an Assistant Professor at the Czech Technical University in Prague during 2017-2019. He was also the Software Engineering Chair funded by Red Hat and the STILL (Software Testing Intelligence) lab co-founder in Prague. He was promoted to Associate Professor at ������ý in 2020 and later to Professor in 2023. His main research work is on software quality assurance, Applied AI, and Trustworthy AI.
