Senior Lecturer, Analytical Informatics and Chemometrics
Pharmaceutical, Chemical & Environmental Sciences
Dr John Tetteh has been involved with applied informatics and chemometrics in the analytical sciences for over 15 years. He has both industrial and academic experience in real-world analytical challenges, including characterisation and optimisation of chemical systems, materials and formulations across the pharmaceutical, food, materials, chemical and allied industries.
He also has extensive experience in multivariate data analysis involving computational methods such as artificial neural network/intelligence and multivariate cure resolutions, experimental designs and data engineering.
Dr Tetteh is an experienced software developer who focuses on tools for multivariate analysis and visualisation. His analytical instrumentation expertise includes FTIR, Raman, Mass Spectroscopy, XRD and advance multidimensional chromatographic systems.
