Dr Lucas Karatzas is currently  a Senior Lecturer in PSB Academy. Having been a post-doctoral research fellow at the prestigious University of Bath and University of Reading in the UK, he has developed a very strong background in research, which led him to take up several senior positions in engineering and marketing with large MNC’s across UK, Germany, Korea, and Singapore. To date, he has contributed 44 publications to academia and has also presented academic papers at 12 international conferences.

Dr Karatzas began teaching in the University of Reading, UK. Thereafter, he relocated to Singapore and became a Senior Lecturer in Robotics and Automation at Temasek Polytechnic before joining the School of Engineering and Technology in PSB Academy.

He graduated with Doctor of Philosophy and Bachelor of Science with First Class Honours from the University of Reading, UK. He also completed the Teaching in Higher Education Certificate (THEC) from Temasek Polytechnic.
