The Power List 2020 – Power List


Deputy Director Enterprise, Frost Professor of Ophthalmology at the Institute of Ophthalmology, University College London, UK

Your three wishes?

I wish that I had obtained a medical degree, as well as scientific degrees.

I wish I understood ageing and could delay or prevent age-related diseases.

I wish we had an understanding of the entire genetic book of man and could really “get to town” on personalized medicine.

Piece of advice to your younger self?

See what everybody has seen but think what nobody has thought – and always be aware of the next technology step.

The funniest moment of your career?

Too numerous to mention as an accident-prone individual. Examples: being electrocuted by a faulty lectern, a giant projection screen falling on my head, falling off the stage, trousers ripping at a crucial moment, zip failures on numerous occasions…

Most unexpected turn your career took…

After many years intensively researching the effects of light and lasers on the retina, to suddenly see the potential of the excimer laser for refractive surgery.
