Dr. Bruce M. McLaren has an extensive background in both research and practical applications, specifically in educational technology, computer-supported collaborative learning, intelligent tutoring, eCommerce, case-based reasoning, and artificial intelligence.

Dr. McLaren is a senior systems scientist at Carnegie Mellon University engaged in research on human learning and educational technology. He is particularly interested in intelligent tutoring systems, e-learning principles, and collaborative learning. McLaren's research with intelligent tutors, for instance, investigates how students learn when presented with erroneous examples in conjunction with tutors (See the AdaptErrEx project webpage). Dr. McLaren has also conducted a series of experiments investigating how chemistry students learn when presented with polite hints and feedback from an intelligent tutor (See the Stoich studies webpage). Dr. McLaren also has interests in collaborative learning and technology for analyzing collaborative argumentation. In his work in Germany as an adjunct principal researcher at the Center for e-Learning Technology (CeLTech) and the German Research Center for Artificial Intelligence, Dr. McLaren has focused on developing educational technology using AI techniques to help teachers moderate collaborative e-Discussions and online arguments (See the projects LASAD, ARGUNAUT, and Metafora). Dr. McLaren has over 90 publications spanning peer-reviewed journals, conferences, workshops, symposiums and book chapters.

Dr. McLaren also has over 20 years experience in the commercial sector, applying research ideas to practical problems. As Director of eCommerce Technologies at OpenWebs Corporation from 2000 to 2002, he led a group of engineers in the development of an intelligent inter-company (B2B) trading product. He was also the leader of many expert system projects during over 10 years working for Carnegie Group, Inc. (now Logica) and Carnegie (U.K.) Limited.

Dr. McLaren holds a Ph.D. and M.S. in Intelligent Systems from the University of Pittsburgh, an M.S. in Computer Science from the University of Pittsburgh, and a B.S. in Computer Science (cum laude) from Millersville University. He has been a member of many academic conference and workshop committees and, most recently, was the local organization co-chair for ITS-2010. Finally, Dr. McLaren is the co-holder of two patents and one patent pending.
