Overview
Michael Gehm received a B.S. in Mechanical Engineering from Washington University in St. Louis in 1992. He earned his A.M. and Ph.D. degrees in Physics from Duke University in 1998 and 2003, respectively. From 2003–2005, he was a Research Associate in ECE at Duke, followed by a year as an Assistant Research Professor. In 2007 he was appointed an Assistant Professor of ECE and was jointly appointed an Assistant Professor of Optical Sciences in 2009. He was promoted to Associate Professor of ECE and Optical Sciences in 2013 before returning to Duke as an Associate Professor of ECE later that year. He added a secondary appointment in Physics in 2021. In 2022, he was promoted to Professor of ECE and Physics.
His current research interests are primarily computational and compressive sensing and measurement in all modalities (with special emphasis in Electromagnetic/Optical from RF to x-ray and all forms of Mass spectrometry), with side interests in optical physics, high-performance x-ray simulation, and rapid-prototyping as a means of creating advanced electromagnetic structures.
He is a Fellow of both Optica (formerly, OSA) and SPIE.

A super-resolution coded aperture miniature mass spectrometer proof-of-concept for planetary science
Journal Article International Journal of Mass Spectrometry · January 1, 2025 Mass spectrometers are essential instruments for in situ analysis of planetary materials. Ideally, a space flight mass spectrometer would have a mass range from ∼10 u to at least 500 u to enable analysis of organic molecules to aid in searching for the req ...

Journal Article Applied Optics · September 1, 2024 Given two aerosol plumes—one scattering and one absorbing—in the presence of a bright interferent, it has been shown that the image contrast ratio through the pair of plumes is different in the two opposing view directions [Appl. Opt. 54, 12 (2015)]. Here, ... Full text CiteToward One-Way Smoke: Synthesis of Copper-Based Microclubs with Asymmetric Scattering and Absorption
Journal Article Advanced Functional Materials · July 17, 2024 The ultimate goal of this work is to create an engineered aerosol that acts as one-way smoke, i.e. it creates an asymmetric vision environment in which the ability to image objects depends on the viewing direction. To this end, a rapid, one-pot synthesis o ... Full text CiteRecent Grants
