Christian Liedtke: Crystalline cohomology, period maps, and applications to K3 surfaces
Abstract: I will first introduce K3 surfaces and determine their algebraic deRham cohomology. Next, we will see that crystalline cohomology (no prior knowledge assumed) is the "right" replacement for singular cohomology in positive characteristic. Then, we will look at one particular class

Ben Howard: Supersingular points on som orthogonal and unitary Shimura varieties
To an orthogonal group of signature (n,2), or to a unitary group of any signature, one can attach a Shimura variety. The general problem is to describe the integral models of these Shimura varieties, and their reductions modulo various primes. I will give a conjectural description of the s

Droplets bouncing on a superrepellent surface
Intricately etched glass and metal surfaces shrug off even the wettest liquids. Surface roughness alone can make a material superrepellent to almost any liquid. Related news story: http://news.sciencemag.org/technology/2014/11/bed-nails-surfaces-just-won-t-get-wet Read the research here:
