Tom van Dijk

I am a postdoctoral researcher at the Institute for Formal Methods and Verification at the Johannes Kepler University Linz. My current research topic is parallelizing 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 (thesis) in the Formal Methods and Tools group at the University of Twente, where I studied parallel decision diagrams algorithms.

Furthermore I have hobbies, such as engaging in politics, surfing on reddit, playing computer games, and various obvious other interests like eating tasty food and watching decent 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 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.
