About

15 years experience in downstream processing. During this time experience has been gained in all aspects of downstream processing, from clarificaiton through to drug substance formulation. Currently leading the robustness and tech transfer team, responsible for applying QBD to early stage projects prior to transfer of process. Also act as technical expert in support of GMP manufacture previously my role has been in process development and tech transfer. Have optimised platform processes as well as introdcuing new technologies to the DSP tool box such as membrane chromatography and various clarification technologies. Specialties: The use of Design of Experiments for process optimisation, identification of design space and application of QbD. Problem solving Intorducing new technologies to increase efficientcy and cost of goods
