Eric Klopfer's research focuses on the development and use of computer games and simulations for building understanding of science, technology, engineering and mathematics. The games that he works on are designed to build understanding of scientific practices and concepts as well as critical knowledge, using both mobile and web-delivered game platforms. In the realm of simulations, Klopfer's work focuses on students understanding complex systems through, and connecting computer programming with scientific practice, critical thinking, and real-world issues. He is the co-author of the books, "Adventures in Modeling", "The More We Know", and the upcoming "Resonant Games", as well as author of "Augmented Learning," His lab has produced software including the UbiqBio line of mobile biology games, and the Massively Multiplayer game, The Radix Endeavor, as well as platforms such as StarLogo TNG for modeling complex systems, Taleblazer for creating augmented realities, and Gameblox for making games online. His work also includes a series of Massive Open Online Courses known as edTechX, which cover educational technology and games. His work has been funded by federal agencies including NIH, NSF and the Department of Education, as well as the Gates Foundation, the Hewlett Foundation, and the Tata Trusts. Klopfer is also the co-founder and past President of the non-profit Learning Games Network.
