Dr Michael Gamlen
Dr Michael GamlenFounder and CSO
Michael is a graduate with first class honours in pharmacy (specialising in pharmaceutical engineering) of Sunderland University and has a PhD from Nottingham University. At Nottingham he trained with Professor JM Newton, one of the UK’s leading tableting researchers and the first person to use tensile fracture stress measurements to evaluate tablets.

Michael spent a year at Beechams Pharmaceuticals working on a completely novel technique to instrument a rotary tablet press. He then joined Wellcome Foundation, where for 14 years he was responsible for development of all tablet formulations including hundreds of clinical trial formulations as well as licensed products (of which many are still on the market).

The team A to Z

Chi Chi Oparaeche
Chi Chi OparaecheLaboratory and Production Manager
Chi Chi joined Gamlen Tableting in 2013. Her area of expertise is in the compaction and analysis of pharmaceutical excipients used in drug formulation. Based at our London laboratories, Chi Chi is Gamlen Tableting’s in-house specialist in using the Gamlen tablet press (Gamlen R series) and powder compaction analyser (PCA) for materials characterisation. Together with the laboratory team, Chi Chi oversees a range of Gamlen Tableting services including: sample testing, compaction studies of the behaviour of pharmaceutical materials, pre and post drug development and many more.

Chi Chi studied pharmacology at University College London and she is currently completing a PhD at the University of Greenwich in materials characterisation.

Henry Kafeman
Henry KafemanProduct Development Director
Henry has over 30 years of experience working in many engineering disciplines and has proved to be an invaluable asset. His ability to combine creative thinking with engineering excellence has resulted in a significant contribution to product development. His innovations include the unique patented rotating die for the Gamlen Instruments’ Powder Compaction Analysers (PCA), which measures detachment force in addition to compaction and ejection forces. He has worked with other members of the team and Microsoft Excel experts to develop the Gamlen Instruments’ “Dashboard” for basic data analysis and visualisation. For deeper understanding and for larger data sets, he has developed a MathWorks Matlab toolbox operating in conjunction with a SQL Server Database which is providing unique insights.

Henry earned his MA in engineering at Queens’ College, University of Cambridge. His experience includes software engineering (support and troubleshooting as well as development), data analysis and visualisation electronics/PCB design and simulation, embedded systems, databases, wireless communication, mechanical engineering and pneumatics.

Dr Rebecca McVicker
Dr Rebecca McVickerProduct Director
Rebecca joined Gamlen instruments in 2019. She previously worked as a Materials Scientist at GSK for three years where she characterised active pharmaceutical and excipient powders. Her focus was on oral solid dose formulations and compaction behaviour.

She completed her PhD in Catalysis at Cardiff University in 2014 under the supervision of Prof. Graham Hutchings. Her PhD title was the “The Selective Low-Temperature Oxidation of Methane by Quasi-Heterogeneous Catalysis” which resulted in a paper being published in Science. She secured funding from Exxon Mobil to continue working as a post-doctoral researcher for the following year in the same group.

She completed her BSc (Hons) degree in Chemistry at the National University of Ireland, Galway in 2010 before spending a year as a research trainee at the University of South Australia studying the rheological behaviour of oil in water emulsions.
