Transport of molecules through nanoscale pores is a process fundamental to the biology of all living organisms and a key element of many technological processes. Driven by diffusion, electrophoresis, or direct mechanical pulling, the transport can be highly selective and is regulated through a variety of mechanisms, including steric exclusion, electrostatic trapping and dehydration. In this colloquium, I will review our discovery of new mechanisms that can govern transport of biomolecules to and through nanoscale pores. I will describe how the physical insights uncovered through computer simulations can be applied to block nanoscale transport in the absence of physical gates, to deliver biomolecules for nanopore sensing and to kill cancer cells


Fast Company (Jan. 30) -- Every year, tens of billions of pounds of perfectly edible food are thrown out by restaurants, groceries, catering companies, and delis. In Chicago, two computer science Ph.D.s --Rajesh Karmani and Caleb Phillips--are trying to bring that number down to zero, with a little bit of logistics and a lot of code. “What keeps me up at night is the fact that there’s still food in the dumpsters,” says Phillips. Their company--Zero Percent--started out simply, somewhere between Karmani’s home and the University of Illinois at Urbana-Champaign, where he was a grad student.
