One of the strengths of Presenting Science is the complementary skills of its two directors. Ted Lister is a science teacher, writer and educational consultant and Alex Renshaw is a research physicist turned software engineer. With this blend of skills we can tackle a wide variety of projects whilst ensuring that the work is done in-house, by people who really understand the underlying science.


After graduation from Warwick University (1st Class Honours in Molecular Sciences), Ted spent more than 20 years as a science teacher, and was Head of Science at the Trinity School, Leamington Spa. During this time he co-authored the best-selling Understanding Chemistry for Advanced Level, obtained an MEd, and was elected to Fellowship of the Royal Society of Chemistry (RSC).

Outside of teaching, Ted has worked as a freelance science and science education writer, teacher, lecturer and consultant. This has included regular contributions to The Guardian and New Scientist, editing the magazines Catalyst and Reaction!, and producing the videos Modern Chemical Techniques and Industrial Chemistry for Schools and Colleges.


Alex graduated from Oxford University (1st Class Honours in Physics), and went on to complete a DPhil in the Crystallography Group. After completion of his doctorate, Alex continued research into new software techniques for crystallography before joining Oxford Cryosystems as Head of Software Development. Here he managed the development of the Crystallographica suite of software, which is now used for teaching and research in 80 countries around the world, as well as running the software consulting arm of the business, with customers including Philips, NIST and Oxford Instruments.

An early enthusiast for the web and its associated technologies, Alex is responsible for the design and programming of a number of web sites and CD-ROMs, and his skills include C++, SQL, Pascal, Java, Javascript, HTML and VRML.
