Dr. Jeyan Thiyagalingam BScEng(Hons), PhD (Imperial), FBCS, FHEA, MIEEE, MIET
Head of the Scientific Machine Learnig (SciML) Group


Prior to joining STFC-RAL,  I was an assistant professor in the school of Electrical Engineering and Electronics and Computer Sciences at the University of Liverpool. Prior to that, I was based at MathWorks; and at the University of Oxford both as a post-doctoral researcher and later as a James Martin Fellow focusing on high performance, Big data and energy efficient computing. I am also a member of the HiPEAC Network. I have a very strong background on high performance computing, scientific data processing algorithms, signal processing and machine learning. Previously, I was a co-investigator on several grants, including Big Hypothesis (£2.5M from EPSRC).
