Haniel Barbosa

NOTE: I have moved to the University of Iowa as a postdoc. My new webpage is here. This one is old and no longer maintained.

Since December 2013 I am a PhD student at Inria Nancy (also associated with Université de Lorraine/FR and UFRN/BR) under the direction of Pascal Fontaine.

I work with instantiation and proof production in SMT solving and I am one of the developers of the veriT solver.
