Science, Emotion AI, and Egyptian American Innovation
From femtochemistry to Emotion AI, Ahmed Zewail and Rana el Kaliouby show how science becomes global impact.

Caltech Professor and Nobel Laureate
California Institute of Technology
Ahmed Zewail was an Egyptian American chemist, Caltech professor, and Nobel laureate known as a founder of femtochemistry. His ultrafast laser work made it possible to observe chemical reactions at femtosecond timescales, earning him the 1999 Nobel Prize in Chemistry and a lasting place in modern science.
