practices, such as argumentation, explanation, and modeling, meaningful and effective for classroom teachers and students. Reiser leads the MoDeLS project (Modeling Designs for Learning Science), to develop an empirically based learning progression for the practice of scientific modeling, and BGuILE (Biology Guided Inquiry Learning Environments), developing software tools for supporting students in analyzing biological data and constructing explanations. Reiser is also on the leadership team for IQWST (Investigating and Questioning our World through Science and Technology), a collaboration with the University of Michigan developing a middle school project-based science curriculum. He was a founding member of the first graduate program in learning sciences, created at Northwestern, and chaired the program from 1993 to 2001. He was co-principal investigator in the Center for Curriculum Materials in Science, exploring the design and enactment of science curriculum materials. At the National Research Council, he served on the panel authoring the report Taking Science to School. He also served on the editorial boards of Science Education and the Journal of the Learning Sciences. He has a Ph.D. in cognitive science from Yale University (1983).
Rebecca R. Richards-Kortum is the Stanley C. Moore professor of bioengineering at Rice University. She is a member of the National Academy of Engineering. Her work has focused on translating research that integrates advances in nanotechnology and molecular imaging with microfabrication technologies to develop optical imaging systems that are inexpensive and portable and provide point-of-care diagnosis. This basic and translational research is highly collaborative and has led to new technologies to improve the early detection of cancers and other diseases, especially in impoverished settings. Over the past few years, Richards-Kortum and collaborators have translated these technologies from North America to both low-and medium-resource developing countries (Botswana, Brazil, India, Mexico, and Taiwan). She served on the inaugural National Advisory Council for Biomedical Imaging and Bioengineering for the National Institutes of Health (2002-2007) and was elected fellow of the American Association for the Advancement of Science and Biomedical Engineering Society (2008). At the National Research Council, she served on the Committee on Being a Scientist: Responsible Conduct in Research. She has a Ph.D. in medical physics and an M.S. in physics from the Massachusetts Institute of Technology.
