I am interested in a wide range of problems involved in the preparation and execution of super resolution microscopy research. I support multiple project with design and instrumentation support. My interests include new technologic developments in fluidics, CFD, charged particle production/control, and vacuum system design.

Tapered image charge detector for measuring velocity distributions of submicrometer particle scattering

Review of Scientific Instruments 91 063305 (2020) | Journal

A novel detector for measuring the post-impact velocities (trajectory and speed) of charged submicrometer particles is presented. A stack of tapered cylindrically symmetric electrodes connected to a set of image charge detection circuits is used in conjunction with an image-charge-sensitive target to measure the incident velocity and scattered trajectories of charged particles following impact with the target. This particle detector is used in conjunction with a mass, charge, and energy-selected source of collimated charged particles. Polystyrene latex spheres were used to characterize the performance of the detector, and examples of scattering trajectories are analyzed to demonstrate detector functionality. Measurements of the coefficient of restitution for 500 nm diameter tin particles are also reported and compared with previous measurements performed with a simpler image-charge detector. Finally, the angular distribution for 500 nm tin particles scattering from highly polished molybdenum at an incident velocity of 150 m/s is reported.

Miller, M.E.C., Characterizing the Impact Dynamics of Small Particles: The Aerosol Impact Spectrometer. Ph.D. Dissertation, University of California San Diego, La Jolla, CA

Morgan Miller studied Physics (B.S.) at the University of California, San Diego (UCSD) from 2010 to 2014. He received his Ph.D. in the Nanoengineering department at UCSD in 2020, working with Prof. Robert Continetti. His research topic was the development of novel laboratory instrumentation for studying the impact dynamics of sub-micron particles in collaboration with both ASML and the Jet Propulsion Laboratory. After graduating he joined the research groups of Dr. Stojan Madzunkov (Planetary Mass Spectrometry) and Dr. Morgan Cable (Exobiology Extant Life Surveyor) as a postdoctoral researcher. Morgan accepted a position in the Life Science Mass Spectrometry RnD group of Thermo Fisher Scientific in 2021 with the ion source development team. In 2024 he joined the group of Prof. Vahid Sandoghdar at the Max Plank Institute for the Science of Light to work on experimental development in iSCAT microscopy.
