Executive team

Alan Hale - CEO
Alan (1 of 1).jpg

Alan has over 35 years’ industrial experience in biotech and technology working in a range of commercial (large, SME and start-up), academic and public sector organisations. He started his career in big pharma before moving into biotechnology. He has directed Research and Development in life sciences, enabling technologies and energy sectors and in technology areas as diverse as synthetic biology, pharmaceuticals, genetics and text analytics.

Alan is experienced in developing new companies in the early stages and in raising finance. His breadth of experience in a range of industry sectors and types plus his hands-on operational knowledge of how to make an organisation work effectively, combines well with his experience working with entrepreneurs and early stage technologies. This expertise provides for a strong strategic focus in Biotangents and his clear vision, balanced with the understanding of how teams can deliver on the ground, is supported by his strong people skills.


Alan contributed in an advisory capacity to the development of Biotangents from its embryonic stage and formally joined the company as CEO in November 2016.

Lina co-founded Biotangents with Andy in 2015 and now leads Biotangents’ diverse research and development team of molecular biologists, bioinformaticians and engineers in the delivery of diagnostic solutions for infectious diseases in livestock. She is a winner of AccelerateHer and was highly commended at the Scottish Women’s Awards in 2019, both competitions celebrating the achievements of female entrepreneurs.

Lina completed her undergraduate studies in Molecular Biology at Vilnius University and holds an MSc in Biotechnology from the University of Edinburgh. After graduation, Lina continued to work with DNA assembly and metabolic engineering of bacteria in the synthetic biology industry. As a Senior Scientist at a synthetic biology company, she delivered varied projects involving DNA design, assembly and biological engineering in collaboration with the University of Edinburgh, local SMEs and multinational companies.

Andy founded Biotangents with Lina in 2015 and led grant-funded and commercial revenue-generating scientific projects in the company’s early years. As the company grew, Andy increasingly focused on the operational aspects of the business, leading him to become the Director of Operations in 2018. In this capacity, Andy has overseen the building of a multifunctional, multidisciplinary team of 11 and the move to the company’s current laboratory premises at the Pentlands Science Park in 2019.

Andy holds a DPhil from the University of Oxford, where he used genetic engineering approaches to provide new insights into how plants control the production of metabolites that are used as some of the most critical drugs in cancer chemotherapy. On his return to Edinburgh, where he had previously obtained his BSc (Hons) in Biotechnology, Andy worked as a Senior Scientist in a University of Edinburgh-based start-up. Here he delivered collaborative projects as varied as synthetic promoter design and polysaccharide biosynthesis.
