I'm currently (fall 2013) a third year graduate student at the University of Pennsylvania. My thesis, still in its infancy, concerns maps from fundamental groups of complete curves over fields of positive characteristic into linear groups.

It's implied here that $H$ is a closed subgroup. Otherwise the quotient map $q$ would not be continuous.
