ABOUT THE SPEAKER
Tal Danino - Synthetic biologistTal Danino explores the emerging frontier of combining biology and engineering (and art). He is a 2015 TED Fellow.
Why you should listen
Tal Danino's research explores the emerging frontier of combining biology, engineering and medicine. His work as a synthetic biologist focuses on reprogramming bacteria to detect and treat diseases in our bodies such as cancer.
Originally from Los Angeles, Danino received B.S. degrees from UCLA in Physics, Chemistry and Math, and received his Ph.D. in Bioengineering from UCSD. He did a postdoctoral fellowship at the Massachusetts Institute of Technology and is currently an assistant professor at Columbia University in New York.
Danino's work has been published in scientific journals and highlighted in several popular press venues. He actively develops "Bio-Art" projects that share perspectives and stories about science with recent projects featured in the New York Times, WIRED, and the Wall Street Journal.
