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 moved to the University of Arizona as 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 proof of concept in a cycloidal coded aperture miniature mass spectrometer.

Journal Article Rapid communications in mass spectrometry : RCM · May 2025 RationaleHigher resolution in fieldable mass spectrometers (MS) is desirable in space flight applications to enable resolving isobaric interferences at m/z < 60 u. Resolution in portable cycloidal MS coupled with array detectors could be improved ... Full text Cite

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 ... Full text Cite

Asymmetric imaging in the presence of a bright interferent

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 Cite
