Tom van Dijk

I am a Postdoc researcher at the Institute for Formal Methods and Verification at the Johannes Kepler University Linz. My current research topic is in symbolic model checking using SAT-solving. I am primarily motivated by making usable tools for scientific calculations, in particular model checking, and studying better algorithms for scientific problems. I obtained my PhD in the Formal Methods and Tools group at the University of Twente, where I studied parallel decision diagrams.

Furthermore I have hobbies, such as engaging in politics, surfing on reddit, playing computer games like the Discworld MUD and World of Warcraft, and various obvious other interests like eating and watching good movies.

Other accomplishments

  • From 2000 to 2003, I developed a number of game modification programs in Visual C++ to customize the computer game The Sims. One of these programs was published and sold worldwide by Abacus under the name Career Creator Pro.
  • Two consecutive projects involving high-speed real-time sensor controller software in C for a R&D project of Scangineers/ScanPoint, a company that developed Self Service Checkouts. I was the (only) software developer in this project.
  • Secretary of the board (2006-2007) of the student association VGST.
  • Chairman (2012-2013) of the Jonge Democraten Twente, the regional department of the Jonge Democraten, a political youth organisation associated with the national party D66.
  • As part of a volunteer team, I’ve worked on several web development projects for the Jonge Democraten, see my GitHub.
  • As a member of both the Economy and the Sustainability study groups of the Jonge Democraten, I helped organize a national symposium (“Duurzaam denken & duurzaam ondernemen”, january 2015) on environmental sustainability in business, in which I managed technical aspects and organized several speakers.
  • As a part of the international volunteer organization Crusaders of Honor, I participated in defending Azeroth from many foes, including the demise of the demon Archimonde in Mythic difficulty on March 3rd 2016.
