Gishan Don Ranasinghe

PhD Student



Gishan joined the University of Cambridge in 2017 to pursue an EPSRC funded PhD in Predictive Maintenance and 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 the predictive maintenance of industrial equipment. Whilst Dr Ajith Parlikad is Gishan's PhD supervisor, Prof Mark Girolami and Prof Duncan McFarlane are his PhD advisors.

Before starting the PhD, he completed a master’s degree in Computer Science and Artificial Intelligence at the University of Nottingham. He completed internships at Roller Agency and JP Morgan during his bachelor’s degree at the University of Nottingham which was also in Computer Science and Artificial Intelligence.

With regards to work experience, 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 and 2018 Fitzwilliam College, Cambridge Senior Scholarship.
