Sub teaches a range of subjects spanning physical and analytical chemistry. With particular expertise in smart materials and biosensors, Sub has led collaborative research projects and teams with funding from EPSRC, The Wellcome Trust, The Leverhulme Trust, The Royal Society and The Royal Society of Chemistry. In recognition of contributions to Chemistry research and teaching, Sub is a Fellow of the Royal Society of Chemistry and Fellow of the Higher Education Academy.
Sub has published widely in Materials and Analytical Chemistry and Biosensors. He is a Founder Series co-Editor of a 15 Book Series in Detection Science commissioned by RSC-publishing (from 2011-present) and sole Editor of one book in the Series entitled Advanced Synthetic Materials in Detection Science.
Sub is an internationally leading researcher in molecularly imprinted polymers (MIPs) and their application in electrochemical, optical and acoustic-based biosensing. His lead unique and original contributions to science to date have been (1) the first publication of protein crystallisation facilitated by MIPs (Saridakis, Khurshid et al. 2011); (2) physical characterisation of hydrogel-based MIPs capable of protein recognition (El-Sharif, Hawkins et al. 2014) and (3) the signal amplification of quartz crystal based biosensor strategies (Karousos, Aouabdi et al. 2002). Sub's smart materials work has resulted in the application and granting of UK patents, over 55 paper publications and 20 invited talks at international conferences and workshops. His recent grants as PI and co-PI are from The Wellcome Trust and The Leverhulme Trust. Sub has had papers published in PNAS (Saridakis, Khurshid et al. 2011) and Biomacromolecules (Reddy, Phan et al. 2012) (as a senior corresponding author) for his work on using MIPs for the first time as novel and selective nucleants for protein crystallization and MIP-based protein biosensors. The latter has been in collaboration with Imperial College. The research led to granting of a UK patent (Reddy, SM and Chayen, NE, UK, Patent Application No. 0909502.7; granted 2014) and the technology is now being commercialised through a joint venture between University of Surrey and Imperial College. This is now generating knowledge transfer-based income. Sub has been invited on multiple occasions to be a Panel Member on EPSRC Grant Awarding Panels in Chemistry and Materials and has also been invited to be a Roving Panel Member (2015). He has also presided on RSC studentship Funding Panels. In 2015, he was admitted as Fellow of Royal Society of Chemistry. His research has been featured in Nature Methods Research Highlights for MIPs facilitating protein crystallisation (2011). He is an invited Series co-Editor of a 15 Book Series in Detection Science commissioned by RSC-publishing (from 2011-present). He is also involved in the public communication of science and of his research through stand-up comedy (Bright Club; 2012;2013) and has also appeared on BBC2 in ‘Some boffins with jokes’ as well as at the Edinburgh Fringe (2013) and Winchester Science Festival (2014).
