Prof. J. Rohan Lucas

Professor Rohan Lucas is an Emeritus Professor of Electrical Engineering of the University of Moratuwa and an Chartered Electrical Engineer.

Having graduated with a BSc Engineering degree from the University of Ceylon in Peradeniya and postgraduate degrees from the University of Manchester (UMIST), he has over 40 years of postdoctoral experience in teaching, research and professional experience, in Sri Lanka, United Kingdom, Canada and New Zealand.

In recognition of his contributions, he has been honoured by the naming the newly refurbished high voltage laboratory as the Rohan Lucas High Voltage Laboratory on 17th October 2017. 

Professor Rohan Lucas began teaching at the Ceylon College of Technology, Katubedda (now renamed University of Moratuwa) on the degree programme nearly fifty years ago on 13th March 1970. He has been bestowed the Engineering Excellence Award by the Institution of Engineers Sri Lanka in September 2013, many Research Excellence Awards and the Teaching Excellence Award by the University of Moratuwa on the eve of his retirement. Having retired from formal employment on 31st March 2014, he continues to serve society in various capacities, including academic and as an Electrical Consultant. On 17th October 2014, he brought out his autobiography "A Tongue-in-cheek Autobiography of Prof. Dr. Eng. Rohan Lucas, including memories of others". The video of the launch is in 5 parts, namely  Part 1 - A Review by Prof Willie Mendis (16:36 min), Part 2 - Launch of website prof.rohan.lucas.lk by Prof Gihan Dias (9:07 min), Part 3 - A Self Introduction (33:59 min), Part 4 - Reminescences of Eng U D Jayawardena (10:56 min) - Part 5 - Reminescences of Hon Patali Champika Ranawaka (13:58 min).
