    Raman spectroscopy of infrared multiphoton excited molecules, at XIVth Int. Quantum Electronics Conf. (San Francisco, CA), Wednesday, January 1, 1986
    Anti-Stokes signals from various modes of isolated, infrared multiphoton excited SF6 and C2H4F2 molecules are measured as a function of pressure, infrared fluence and wavelength. This allows to verify whether intramolecular equilibrium of vibrational energy is established after infrared multiphoton excitation in isolated molecules.
    Multiplex CARS study of infrared-multiphoton-excited OCS, at Ninth International Conference on Laser Spectroscopy (Bretton Woods, NH), Thursday, June 1, 1989
    The vibrational energy distribution following the ?2 overtone excitation of OCS by a pulsed CO2 laser can be studied by coherent anti-Stokes Raman spectroscopy (CARS) of the ?1 mode. Since the anharmonicity of the pumped mode is small, and since the relaxation to other modes is slow, OCS allows one to study the interaction of an isolated harmonic mode with an intense laser field. Single-shot spectra are obtained by using a broadband dye laser and recording the CARS signal on a multichannel analyzer. The phase matching of the beams is done in a so-called folded boxcars arrangement. The... Read more about Multiplex CARS study of infrared-multiphoton-excited OCS
    Two-photon engineered polymer scaffolds for 3D migration studies, at MRS Fall Conference 2006 (Cambridge, MA), Wednesday, November 29, 2006
    In tissue engineering, control of ligand-receptor-mediated interaction between cell and material is an underlying principle for designing biomaterials. Microfabrication techniques such as soft lithography have enabled researchers to study cell behavior extensively in two dimensions (2D) by controlling the spatial distribution of ligands on a micrometer and sub-micrometer scale. However, lack of an appropriate three-dimensional (3D) microfabrication technique with micrometer resolution has prevented from presenting cell adhesion ligands in an organized fashion in 3D. Thus, fabricating such a... Read more about Two-photon engineered polymer scaffolds for 3D migration studies
    Academic Physicists' Introductory Teaching Improvement Efforts at Major Research Universities, at American Association of Physics Teachers Summer Meeting 2010 (Portland, OR, USA), Saturday, July 17, 2010
    There is no shortage of PER literature describing research-based, instructional strategies for improving teaching in introductory college physics courses. [1] It remains, however, that most physics faculty with visions of improved teaching based on such strategies must overcome significant barriers, including a reward system structured to direct faculty attention toward research and away from pedagogy. [2] Barriers to teaching improvement are compounded at major research universities (MRUs), where science faculty must balance extreme demands for research productivity with their teaching...

    Researching Implementation of Instructional Change in the Advanced Physics Laboratory, at American Association of Physics Teachers Summer Meeting 2010 (Portland, OR, USA), Saturday, July 17, 2010
    Abstract Body: Although physics education research on the implementation of instructional change in introductory physics laboratories is on the rise, dissemination of research on such change in advanced undergraduate laboratory courses is still lagging. This gap presents a problem for faculty seeking to improve students’ learning in advanced laboratories by using research-based pedagogies. In this study, we analyzed interview, observational, and course data to investigate four instructional changes implemented for the first time in an advanced physics laboratory course at one major research...

    Assessing and Enhancing Student Learning in the Advanced Physics Lab, at AAPT Summer Meeting, 2010 (Portland, Oregon), Monday, July 19, 2010
    Efforts to reform instructional physics labs--by defining measurable goals and improving student learning--have led to several innovations (i.e. rubrics for enhanced formative assessment) at the introductory level. However, researchers have yet to explore similar innovations in advanced laboratory courses. In an effort to fill this void, we investigated the observable aspects of student learning, culled from submitted written work and discussions between students and faculty, in light of specific changes to the advanced lab course (clear statement of learning goals, better-defined activities...
