About Dr Mahalingam

Dr Sunthar Mahalingam (SM) gained his BSc (Engineering) honours degree from the University of Moratuwa in Sri Lanka in 2004 and subsequently completed his PhD at University College London (UCL) in September 2008 after researching electrohydrodynamic processing of functional materials for optical and electronic applications.

During his doctoral research he developed the key concepts of high voltage electric jet-assisted deposition of crack-free semiconductor thin films from precursor sols relating the process control parameters/jet characteristics to the microstructure and properties of the films (e.g. Journal of Physics D:41(2008)215406), novel work very relevant to the thin film industry. Subsequently, he worked as a research assistant at Applied Kilovolts Ltd in Brighton and developed a noise measurement system for high voltage power supplies.

He was then appointed a research associate in the Interface Analysis Centre at Bristol University where he studied crack initiation and propagation in polycrystalline metals and alloys with a collaborative research team spanning Bristol-Birmingham universities. During this time he also developed the concept of in-situ mechanical testing of materials in the focussed ion beam microscope.

Thereafter he joined UCL as a research associate and developed novel manufacturing of polymer nanofibers and structures for biomedical engineering and drug delivery. He worked in different projects in collaboration with School of Pharmacy and Civil and Environmental Engineering.

Currently, he is working with Professors Mohan Edirisinghe and Shervanthi Homer-Vanniasinkam in the Department of Mechanical Engineering, developing new methods to manufacture advanced functional materials and structures for biomedical engineering.
