    Venturing toward better teaching: Professors' knowledge base for pedagogical improvement in introductory STEM classrooms at major research universities., at The Association for The Study of Higher Education Annual Meeting (Vancouver, BC, Canada), Thursday, November 5, 2009
    Educational reformers often portray the majority of science, technology, engineering and mathematics (STEM) professors at American research universities as subject-matter experts but pedagogical novices (Baldwin, 2009; Boyer, 1998; Coopala, 2009; Handeslman et al., 2006; Wieman, 2006). Images of STEM professors as lacking knowledge about best teaching practices are especially prevalent in discussions about academic researchers: A wide array of constituents, from students and journalists to scholars of teaching and learning, have long proffered views of academic researchers as so heavily...

    Less is More: Extreme Optics with Zero Refractive Index, at Physics Colloquium, North Dakota State University (Fargo, ND), Wednesday, April 5, 2017
    Nanotechnology has enabled the development of nanostructured composite materials (metamaterials) with exotic optical properties not found in nature. In the most extreme case, we can create materials which support light waves that propagate with infinite phase velocity, corresponding to a refractive index of zero. This zero index can only be achieved by simultaneously controlling the electric and magnetic resonances of the nanostructure. We present an in-plane metamaterial design consisting of silicon pillar arrays, embedded within a polymer matrix and sandwiched between gold layers. Using an...

    Flat space, deep learning, at Physics Colloquium, Harvard University (Cambridge, MA), Monday, March 28, 2016:
    The teaching of physics to engineering students has remained stagnant for close to a century. In this novel team-based, project-based approach, we break the mold by giving students ownership of their learning. This new course has no standard lectures or exams, yet students’ conceptual gains are significantly greater than those obtained in traditional courses. The course blends six best practices to deliver a learning experience that helps students develop important skills, including communication, estimation, problem solving, and team skills, in addition to a solid conceptual understanding...
