Title: Erdos' distinct distance problem in finite fields

Erdos conjectured that a set of n points in the Euclidean plane has at
least c n/sqrt(log(n))) distinct distances for some universal constant
c>0. Guth and Katz nearly resolved this question, but many related
problems remain wide open. I will discuss recent results on a variant of
this problem for points in a plane over a finite field. This is joint
work with Giorgis Petridis.
