Serkan Topaloğlu received his BS and MS degrees from Department of Electronics and Communication Engineering, Istanbul Technical University, Istanbul, Turkey in 1999 and 2002, respectively. He started his doctorate study in 2003 at University of Duisburg Essen, Germany, Solid State Electronics Department, and received his Ph.D. degree in 2006. He worked at Yeditepe University, Department of Electrical and Electronics Engineering for two years as an Assistant Professor an then he worked at Maltepe University, Department of Electronics Engineering until September 2012 as Assistant Professor. He worked as R&D Director at TRON electronics from September 2012 to April 2015. He attended at Yeditepe University as Assistant professor in April 2015. He received his Associate Professorship from UAK in April 2015. He was titled as Associate Professor at Yeditepe University in September 2015 and since then, he is working as Associate Professor at that university. He is also the coordinator of the RF lab at Yeditepe University (for details please visit: ). He is also Director of Technology Transfer of Yeditepe University (YUTTO) since February 2017 (you may visit:

 An InP/InGaAs SHBT with an emitter area of 2×10 µm2

Serkan Topaloğlu designed a high efficiency 1W Class B push-pull amplifier for HiperLAN/2 as Master thesis. During his Ph.D. studies, he was the process engineer in the project called “InP Electronics for 80 Gbit/s” funded by German Ministry of Research and Education.

In this project, he developed high speed InP HBT (heterojunction bipolar transistors) for low power and high-power RF applications. He optimised layout and process for reliable and reproducible submicron InP/InGaAs SHBT (Single HBT), InP/InGaAs/InP DHBT (Double HBT) and InP/GaAsSb/InP DHBT devices. During his PhD studies, he also worked with ICP-RIE (inductively coupled- reactive ion etching) plasma etching systems from Oxford Instruments (PlasmaLab 100 ICP-65).
