Recently, I had an unbelievable opportunity to meet a scientific hero of mine, Dr. Katalin Karikó, awarded the 2023 Nobel Prize in Medicine. Dr. Karikó’s research on the therapeutic use of mRNA led to effective vaccines against COVID during the pandemic, saving millions of lives. If you remember having had the Moderna or Pfizer vaccine – that was the result of many years of her painstaking effort to harness the power of transcribed mRNA.
Dr. Karikó’s memoir Breaking Through: My Life in Science is a must-read for anyone at any point in their scientific career. It describes her journey from her childhood in Hungary to her experience with academic culture in the United States. When I first read it, I went from cover to cover in one sitting, it is such a compelling story of a remarkable scientific career. The book should be on every scientist’s shelf.
There are also two children’s books written about her life and achievements: Never Give Up: The race for the future of vaccines, and Kati’s Tiny Messengers: Dr. Katalin Karikó and the battle against COVID-19.
It’s just amazing what great scientists like Dr. Kariko can accomplish, and I am always in awe of all those involved in this endeavor.

MUSIC PAGE:
Please click here my carillon (cathedral/church bell) music page! For a number of years I played the largest musical instrument ever designed and built, and wrote some music for it so you can play it too!
THINGS I AM CURRENTLY WORKING ON OR THINKING ABOUT:
Memory: How we make sense and meaning of a world we imperfectly perceive? (with economist John Smith)
Learning: Are we truly Bayesian or merely Bayesian-like in our cognitions? (with economist John Smith).
Social psychology: How does automatic Imitation work and what role does it play in dynamic interaction? (with C. Bouquet and R. van Der Wel)
Environmentalism: How do people think about renewable energy, such as offshore wind? (the basis of my course Environmental Psychology)
Culture, psychology, and food (the basis for my course The Cultural Psychology of Food)
Psychology of art, music and photography (the basis for my course The Psychology of Art and Music)
Psychology of humor (a course I developed and taught for many years)
