  2. 2. Lesson 1 Change is Good • My high school teacher Mr. Wilson said I would be a failure at chemistry • My PhD is in chemistry • The opportunity to live in different places shaped my life • Good friends are forever
  3. 3. Lesson 2 Nurture Friends & Colleagues 50 Years Later
  4. 4. PhD – The Molecular Basis of Cancer Treatment Lesson 3 See things for what they are • I thought I was at the center of the scientific universe • I later discovered I was actually in deep space
  5. 5. Lesson 4: Follow Your Heart • Your head will tell you stuff • Your heart will tell you something different • Follow your heart Circa 1974
  6. 6. Postdoctoral Work – The Molecular Basis of How the Body Works Lesson 5 Learn to live with regret • Regrets: never learnt another language

  10. 10. The Authoring Years
  11. 11. Lesson 6 Make the most of every day
  12. 12. Got Involved with the The Human Genome – Was Only Possible by Applying Computers to Problems in Biology • Took at least 10 years and ~$1Bn • Biology’s equivalent of landing on the moon • We now have thousands of genomes • $50 genome is upon us
  13. 13. Came to UCSD to Apply Computers to Big Biological Problems • Possibly the best place in the world to do computational biology

  27. 27. Lesson 7 – Go After the Big Problems 1. 2. 3. 4. 5. August 14, 2009 Can we improve how science is disseminated and comprehended? What is the ancestry of the protein structure universe and what can we learn from it? Are there alternative ways to represent proteins from which we can learn something new? What really happens when we take a drug? Can we contribute to the treatment of neglected {tropical} diseases?
