Meet a Scientist

What makes a scientist tick?   How did they get started?  What advice do they offer today’s students?  

Find out by viewing these short video interviews with leading researchers from around the world.   They explain their interest in science, from young school-age days
to the present, and share insights with those who may want to pursue their own life in science.  In addition to hearing personal comments, you can link to some related
PI Public Lectures and also read about associated research areas at PI.
