Biography

I trained as a chemical engineer at Cambridge and then UMIST, where I obtained a PhD in Reaction Engineering.

I joined Imperial Chemical Industries as a process engineer in the process innovation, development, plant design and commissioning. I then returned to UMIST as a Lecturer and worked in areas related to chemical and pharmaceutical process development. This was reflected in both my teaching (design, safety, environmental protection among other subjects) as well as my research. My research in process innovation resulted in the award of a Royal Academy of Engineering Chair in Innovative Processing and the establishment of a company BRITEST that still uses my methods today to help industry partners in process understanding and innovation.

I moved to Singapore in 2008 and joined A*Star to work at the Institute of Chemical and Engineering Sciences. There I led a large team working in process innovation, scale-up, safety and modelling, including the ICES Kilolab pilot facility. I joined SIT in 2020.

I am a Fellow of the Institution of Engineers Singapore and have been actively involved with academic accreditation and chartered engineer vetting. I am also a Fellow of the Institution of Chemical Engineers and am a Chartered Engineer myself. 

I live in Bukit Gombak with my family and enjoy travel, good food, cycling and DIY.

Books

  •  “Handbook of batch process design”, Blackie A&P, London, ISBN 0-7514-0369-5

    This handbook is a useful reference for industrial technologists and students in the design of batch chemical processes, and is relevant to the pharmaceutical, fine chemical, agrochemical and specialty sectors. It brings together in one place the central issues that need to be considered in the design and scale-up of batch processes - including scheduling, solvent selection, key unit operations, mixing and safety issues.
