Profile Summary

A fellow of three professional societies, Prof. Spalding has given invited talks widely, and has published on a wide range of optical and electrical topics. He initiated and led an effort that has disseminated 600 single-photon detectors to the advanced instructional labs at a great many colleges and universities and, as PI of NSF DUE grants, funded the training of faculty and staff implementing these and other advanced instructional labs (for which he mentors faculty and staff on integrating programmable Optics into their teaching). Through the Advanced Laboratory Physics Association (ALPhA), where he served as founding President from 2007-2010, he has continued (since 2010) to serve on the committee coordinating the ALPhA Immersions faculty-staff training programs. 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). — He also continues to lead an advisory group on the topic of Photonics, to ensure that this community of instructors remains informed and, more generally, to facilitate the coordination of additional initiatives and partnerships between SPIE, Optica, IEEE, APS, AAPT, ALPhA, and the Jonathan F. Reichert Foundation. Prof. Spalding has served, since its founding in 2014, as Vice-President of the Board of Directors of the 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 ( ). He has also just been elected into the Presidential chain for AAPT, having previously served as the Chair of the AAPT Committee on Physics in Undergraduate Education, and Chair of the AAPT Philanthropy & Special Projects Committee. For 20 years, he has also served as Chair of the conference on Optical Trapping & Optical Micromanipulation, which is the largest conference in the field.

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.
