Profile Summary

I am a fellow of three professional societies, am particularly proud to have disseminated 480 single-photon detectors to the advanced instructional labs at a great many colleges and universities, and to have funded, as PI of NSF DUE grants, the training of faculty and staff implementing these and other advanced instructional labs. In fact, these (combined) programs have already impacted more than one-third of all physics degree granting programs in the United States (and have had some impact globally). — Through the Advanced Laboratory Physics Association (ALPhA) I lead an advisory group on the topic of Photonic Detection, and we aim to partner with SPIE and with the OSA's Photonic Detection Technical Group Committee, to ensure that this community of instructors remains informed and, more generally, wish to facilitate the coordination of additional initiatives and partnerships between SPIE, OSA, APS, AAPT, ALPhA, and the Jonathan F. Reichert Foundation, an ambitious non-profit working to establish programs and grants for hands-on instructional laboratories in physics, beyond the first year of university ( ). I serve as Vice-President of the Reichert Foundation, and am the Chair of the AAPT Committee on Physics in Undergraduate Education. For 15 years, I have also served as Chair of SPIE's conference on Optical Trapping & Optical Micromanipulation, which is the largest conference in the field. I am a well-connected, board-experienced, strategic communicator and design process instructor. I am a physicist.

Course Instructor
SC1043: Shaping Light, with applications in Advanced Microscopy and Optical Trapping
Wavefront correction and generation are important topics in many areas. This introductory course will cover: the basic Gaussian beam, the need for other beams such as: Hermite-Gaussian and Laguerre-Gaussian laser modes, Bessel beams, Airy beams, and other notable beams and how they may be generated. In addition, we will cover some approaches used for adaptive optics / wavefront correction. We will consider uses of Deformable Mirror Arrays, Spatial Light Modulators, Acousto-Optic Deflectors, etc. Applications include sub-diffraction imaging / super-resolution microscopy, OCT, optical trapping, multi-photon microscopy at enhanced depth, and optimal excitation of plasmonic structures.
SC655: Introduction to Optical Tweezers and Optical Micromanipulation
This course is intended as an introduction to systems that use light for actuation and micromanipulation, including examples from the biological and colloid sciences. Throughout, the emphasis will upon basic principles and designs. You will learn of opportunities for enhanced degrees of control, resolution, and sensitivity - as well as many tradeoffs and limitations. The course will provide "hands-on" experience using a real optical tweezers system.
