Profile

Back in the late Cretaceous (when dinosaurs roamed the Earth), Dr Lionel Milgrom obtained his BSc in chemistry (1st Class Honours), followed by an MSc (on haemoprotein model compounds), both from Liverpool University.

The K-T Extinction Event disrupted most things, so he tried his hand(s) at the bass guitar, with some moderate musical (but not much financial) success. The Pleistocene saw his return to academe, when he acquired a PhD on the synthesis and testing of photosynthetic model compounds, from City of London Polytechnic (now part of London Metropolitan University).

A long interglacial began with three consecutive post-doctoral fellowships at Imperial College London, working with Professors Dennis Evans FRS (inorganic chemistry) and John Albery FRS (physical chemistry). An independent academic research career followed which took him to Brunel University (via Kingston University) as Senior Lecturer in Inorganic Chemistry.

His research - on the applications of porphyrin pigments in solar-energy conversion; discotic liquid crystals;  conducting polymers; catalysis, photodynamic therapy (PDT) of cancer and biological targeting of PDT - generated ten PhD students, three post-doctoral fellows, many academic papers and a critically acclaimed  academic text, The Colours of Life published by Oxford University Press.

He has pursued a parallel career as a science writer/journalist with many contributions to New Scientist (as chemistry consultant); Economist; Independent, Independent on Sunday, Daily Telegraph, the Financial Times and Chemistry World (house journal of the Royal Society of Chemistry – RSC – for which he was consulting correspondent ). He was made a Fellow of the Royal Society of Chemistry (FRSC) after serving as a member of its ‘Honest Broker’ committee, investigating mediation between the chemical industries and the environmental lobby.

The Weichsel glaciation led to the closure of chemistry at Brunel, so he returned to Imperial to collaborate with renowned photo-chemist Professor David Phillips CBE, FRS on novel porphyrin-based compounds for PDT. Together with two other colleagues, they formed an anticancer biotech start-up company at Imperial called PhotoBiotics, to research and commercialise imaging and treatment of cancer via targeted PDT. Lionel was its first CEO and scientific director.

The Holocene saw him giving talks to schools and colleges of higher education which later evolved into teaching chemistry at various institutions including Birkbeck College, London Met Uni, University College School and Eton College.

He has an interest in various aspects of complementary and alternative medicine, which has subsequently generated many more academic papers and articles. He maintains active research interest in novel mechanisms for fast enzyme reactions; advances in water science; quantum theory at the macrolevel; investigating the philosophical basis of evidence-based medicine and developing a simple laboratory model of black holes.  He is very old…
