    Factors affecting gender disparity in introductory physics, at APS Centennial Meeting 1999 (Atlanta, GA), Tuesday, March 23, 1999:
    In America, the disparity between the performance of women and men in physics is a matter of common concern; however, it is poorly understood. Is this disparity observed among physics majors at elite institutions as well as non-majors in one-year introductory courses? Does this disparity depend on the pedagogical approach used to teach the class? The high school physics or mathematics background of the students? The gender of the instructor?
    Gender, Educational Reform, and Instructional Assessment: Part II, at Winter Meeting, American Association of Physics Teachers (Philadelphia, PA), Tuesday, January 22, 2002:
    Will current educational reform efforts serve to improve the learning experience of women in physics? To do so, assessment of instructional effectiveness must examine results for male and female students separately as well as for the entire class . We present an analysis of gender differences in performance in introductory physics at eight different colleges and universities; half of the courses were taught using a variety of interactive-engagement methods and half were taught with traditional lectures. We examine the effect of pedagogy and class size on the gender gap in both Force Concept... Read more about Gender, Educational Reform, and Instructional Assessment: Part II
    Early stages of femtosecond laser-induced formation of silicon microspikes, at Materials Research Society Fall Meeting (Boston, MA), Monday, December 2, 2002:
    Arrays of sharp conical spikes form on crystalline silicon surfaces when irradiated with a train of femtosecond laser pulses in a background of sulfur hexafluoride (SF6); blunter, more irregular microstructures form in vacuum. The tips of the spikes are at the height of the original surface of the wafer, suggesting that the formation process predominantly involves removing material. The spikes are arranged in a quasi-ordered fashion with a characteristic nearest-neighbor separation of a few micrometers; the exact value of this characteristic separation depends on the laser fluence and number...

    Reducing the gender gap in introductory physics, at American Physical Society March meeting (Denver, CO), Monday, March 5, 2007:
    We investigated whether the gender gap in conceptual understanding in an introductory university physics course can be reduced by teaching with interactive engagement methods that promote in-class interaction, reduce competition, foster collaboration, and emphasize conceptual understanding. To this end, we analyzed data from the introductory calculus-based physics course for non-majors at Harvard University taught traditionally or using different degrees of interactive engagement. Our results show that teaching with certain interactive strategies not only yields significantly increased... Read more about Reducing the gender gap in introductory physics
