Ulas S. Gokay

Higher Scientist

Ulas S. Gokay is a higher scientist in the Atomic Clocks and Sensors (ACS) group in the Time & Frequency Department, where he works on the research, development, and testing of the compact atomic clock components. Ulas joined NPL in 2023 after completing his second post-doc in the physics and astronomy department of the University of Exeter where he worked on computational imaging and speckle correlations through multimode optical fibres. Prior to this he held a post as optical engineer at the Opto-mechatronic Research Centre (OPAM) in Isik University, Istanbul, Turkey working on the optical design of the adaptive optics enhanced 4m mirror diameter IR telescope of the Eastern Anatolian Observatory project.  

Ulas obtained his PhD on the development of microsphere-based silicon optical resonators for electro-optical applications from the Koc University, Istanbul, Turkey. During this time, he was the chapter president of SPIE as well as a member of the OSA, where he organised various outreach activities for high school students. After his PhD, he stayed with the Microphotonics Research Laboratory (KUMRL) and worked on his first post-doc where he collaborated with the University of Milano and the University of Kyoto for a project of the Scientific and Technological Research Council of Turkey (TUBITAK) to develop diamond based optical waveguides coupled with whispering gallery mode (WGM) optical resonators for quantum information applications.  

Ulas was awarded a full scholarship for his undergraduate degree in physics in Bilkent University, Ankara, Turkey after graduating as a valedictorian from the Izmir Ataturk Highschool (IAL). He obtained his MSc from the Ege University, Izmir, Turkey where he worked on the manufacturing and characterisation of the YBCO bulk superconductors.
