The 'mj stands for Michael Joseph, 'mckeown' is my surname McKeown. In 1985 I was awarded a PhD from the Department of Pharmacy and Pharmacology, at the University of Bath. I have recently retired from teaching, in London, Brighton and the Middle East, after 22 years. Before that, I undertook research for a large medical research charity and for Big Pharma. My resources are largely Slideshows for KS 4 and KS 5 biology. They are ideal for visual learners. They may edited and adapted.
