Outside of school, Gergely is passionate about all things water-sport related, having been a competitive kayaker himself.

Board Member

Mohammad Oulabi is from Aleppo, Syria. He is currently a sophomore studying Logic Information and Computation. As a student who has resettled in different countries several times, he is aware of the difficulties international students face when they first travel to the US to come to Penn. While he was personally pleasantly surprised with the amount of effort ISSS does to welcome international students and make them feel home, by joining ISAB and working with ISSS and other administrators, he plans on doing his best to ensure that international students not only feel welcome when they first arrive, but that they do so throughout their entire time at Penn.
