MORE ABOUT THE INTERVIEWEE :

Kari Dalnoki-Veress has been a Professor at McMaster University, Ontario, since 2010. There, he leads the Dalnoki-Veress Lab, a research group that studies experimental soft matter, and in particular the properties of polymers and living systems.
The topics he has worked on range from the mechanical properties of nematods like C. Elegans, to the glass transition of polymers, but also include elastocapillarity in fibers and films of polymers.
