Dr Diego Pérez-Liebana

Queen Mary University of London.

Born in Madrid (Spain) in 1983 and living in London (United Kingdom). I am a Lecturer in Computer Games and Artificial Intelligence at the University of Essex (Colchester, UK). I hold a Ph.D in Computer Science from the University of Essex (2015) and a Master degree in Computer Science from University Carlos III (Madrid, Spain; 2007).

My research is centered in the application of Artificial Intelligence to games, Tree Search and Evolutionary Computation. At the moment, I am especially interested on General Video Game Playing, which involves the creation of content and agents that play any real-time game that is given to it, and research in Abstract Forward Models. I have recently been awarded with an EPSRC grant on Abstract Forward Models for Modern Games.

I am author of more than 80 papers in the field of Game AI, published in the main conferences of the field of Computational Intelligence in Games and Evolutionary Computation. I have publications in highly respected journals such as IEEE TOG and TEVC. I have also organised international competitions for the Game AI research community, such as the Physical Travelling Salesman Competition, and the General Video Game AI Competition, held in IEEE (WCCI, CIG) and ACM (GECCO) International Conferences.

I also experience in the videogames industry as a game programmer (Revistronic; Madrid, Spain), with titles published for both PC and consoles. I worked as a software engineer (Game Brains; Dublin, Ireland), where I oversaw the development of AI tools that can be applied to the latest industry videogames.

I am particularly interested in supervising students with background on applications of Tree Search or Evolutionary for games.

Research Themes:

  • Game AI
  • Procedural Content Generation
  • Monte Carlo Tree Search
  • Statistical Forward Planning methods.
