Doug Lombardi holds a PhD in Educational Psychology from the University of Nevada, Las Vegas, and is currently an Associate Professor in the Department of Human Development and Quantitative Methodology at the University of Maryland. As the head of the Science Learning Research Group (http://sciencelearning.net), he conducts research examining reasoning and critical thinking about knowledge claims. Much of this research is situated within the context of formal classroom settings and focuses on effective teaching tools and strategies to support deep learning and understanding, particularly about topics that pose local, regional, and global challenges (e.g., causes of current climate change, availability of freshwater resources). His research and theoretical positions have been published in journals such as Educational Psychologist, Science Education, Contemporary Educational Psychology, and Learning & Instruction. Doug has proudly served as an undergraduate research team mentor for the Gemstone Honors Program at the University of Maryland.
