I had the good fortune to receive my first Gates scholarship to study mitochondria-targeted antioxidants and other related chemicals, which could potentially help in the treatment of diseases such a Parkinson disease or Alzheimer's dementia. In 2008 I will study towards a MPhil in the history and philosophy of science, again supported by the Gates Cambridge Trust. Understanding the philosophical basis of modern science is, in my view, crucial if we are to solve the many problems in modern biomedical science and practice - from cognitive sciences to medical ethics.
