Gishan joined the University of Cambridge in 2017 to pursue a PhD in Engineering. In his PhD, he is developing a methodology for predicting equipment failure under the conditions of limited failure data availability and showing its impact on predictive maintenance. Dr Ajith Parlikad is his PhD research supervisor and Prof Duncan McFarlane and Prof Mark Girolami are his advisors.

Before starting the PhD, he completed a Master’s degree in Computer Science and Machine Learning at the University of Nottingham. He completed internships at nuom and JP Morgan during his Bachelor's degree at the University of Nottingham which was also in Computer Science and Machine Learning. Gishan had his primary and secondary education at the Ananda College, Colombo, Sri Lanka.

He has over 7 years of industrial working experience in Software Developer, Software Solutions Architect, and Head of Software Development roles and involved in designing and developing software solutions for companies such as ERT, AstraZeneca, GSK, Novartis, Quorn, MYZONE and HelpAge International.

Gishan is the recipient of IEEE 2019 International Prognostics Best Paper Award, 2018 and 2019 Fitzwilliam College, Cambridge Senior Scholarship, and 2017 Cambridge University-EPSRC PhD Studentship.
