Hi, I am Alex. I am an Associate Professor at the University of Tartu (Estonia) and an Adjunct Associate Professor at Carnegie Mellon University (Pittsburgh, PA, USA). My current research is directed towards studying and designing means to support the sustainability of collaboration and collaboration outcomes. In particular I study and design means to foster the impact of time-bounded events such as hackathons in in the context of communities, corporations, IT entrepreneurship, higher education and civic engagement.
