Dr Gillian Broadbent is a molecular biologist with over 20 years’ experience in the field of protein engineering. She was previously a co-founder and Director of Research and Development for Haptogen Ltd until its sale to Wyeth in October 2007. During her time at Haptogen she was involved in developing human therapeutic antibodies to hapten targets that are difficult to address with conventional antibody generation approaches. She has considerable expertise in the development of recombinant antibodies from a number of sources and in their development for both diagnostic and therapeutic applications. In 2012, she co-founded Scotia Biologics Ltd., where she acts as COO/CFO.


During her time in industry, Dr Broadbent has been involved in the project management of a large number of contracts with external clients as well as internal R&D ensuring that projects were completed on time and materials produced met the specific requirements of the clients. Gillian also has experience of managing collaborations involving companies from all over the world, the longest being an 8 year collaboration with a Malaysian company.

Dr. Keith Charlton obtained his Ph.D. from the University of Aberdeen in 2000, and is a molecular immunologist with over 20 years experience. His main research interest is in the field of antibody engineering, particularly the application of cutting edge technologies to generate high affinity recombinant antibodies from novel sources to challenging antigens, and developing these into commercially successful diagnostic, therapeutic and research reagents. His work has been widely published in the scientific press and presented at numerous international meetings. In 2002 he was one of the scientific founders and director of innovations of Haptogen Ltd., a University of Aberdeen spin-out biotechnology company specializing in generating therapeutic antibodies to antigens not easily targeted effectively by conventional antibody technologies. Haptogen was successfully acquired by Wyeth Pharmaceuticals in late 2007. In 2012 he co-founded Scotia Biologics Ltd., where he acts as CEO/CSO.

Rebecca joined Scotia Biologics Ltd., as a Research Scientist in 2012.  Her role as Principal Scientist involves coordination of multiple projects and team members in order to deliver on Scotia Biologics’ international contracts.  Rebecca is also undertaking a part-time PhD with the University of Aberdeen and the Royal Aberdeen Children’s Hospital on a project to improve the safety of local anaesthetic.

Rebecca’s background includes both small biotech and large international pharmaceutical companies. Her work has involved the building and screening of antibody-phage libraries and protein engineering.  Rebecca has over a decade of experience in protein expression and purification, with the use of instrumentation for high through-put screening and candidate protein characterisation being a particular favourite.

Dr Euan Murray joined Scotia at the start of 2016.  His role as Principal Scientist involves coordinating a number of customers’ projects as well as much of our internal R&D.  When in the lab he is likely to be found building or screening antibody-phage libraries.

Prior to joining Scotia he spent 11 years at The Cancer Research UK Edinburgh Centre in the lab of Ted Hupp. Here he was involved in many interesting and varied molecular oncology projects, covering areas such as cell signaling, proteomics and antibody engineering.  It was during this time that he learned how to carry out phage display; skills now being put to good use at Scotia.

Euan has a BSc in Biology & Chemistry from Abertay University, Dundee and a PhD in Bioorganic Chemistry from Heriot Watt University, Edinburgh.

Steven Humphreys received his B.Sc. (Hons) in Human Embryology and Developmental Biology, and his M.Phil. in Immunology at the University of Aberdeen.  Following his undergraduate studies, he was hired as a Research Assistant at the University of Aberdeen to investigate ongoing efforts to use electrical stimulation on amphibian and/or mammalian cells to improve wound healing and regeneration.  In 2015 he joined Scotia Biologics Ltd. as a Research Scientist developing vaccines based on growth factors.  In 2018 he was promoted to Senior Research Scientist, and in early 2021 was promoted to Principal Scientist.

Steven works primarily as the lead Assay Development Scientist investigating the effects of growth factors and neutralising antibodies on signalling pathways in mammalian cell lines.  Steven also manages all of Scotia Biologics online resources.
