Research interests

My research interests involve developing the use of Fourier transform near infrared spectroscopy (FT-NIRS) for use as an online process monitoring and control system for bioprocesses. This involves the use of multivariate statistical techniques including principle component analysis and partial least squares regression to produce integrated monitoring systems for the bioprocess with a goal of optimising and providing flexibility of the process. An online monitoring and control system for anaerobic digestion would enable plants to be operated at higher feeding rates than currently and also provide the ability to adjust co-digestion feedstocks to minimise the chance of disturbances from occurring allowing greater plant operational flexibility. This includes the assessment of the dewaterability of sewage sludges, in particular the development of robust laboratory scale methods with applicability to industrial scale dewatering processes. I am also involved in work that aims to improve the performance of the use of lignocellulosic feedstocks for 2-stage bioH2/bioCH4 production through the assessment of different pretreatment regimes, particularly the use of combinations of enzymes to enhance hydrolysis of the substrates. Building on previous work, I am also interested in the upgrading of biogas to hydrogen via steam reforming with a focus on modelling of the fuel processing system to reduce the cost of development of this technology.
