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.

The impact dynamics of ice grains on surfaces as a function of velocity, including particle breakup and impact ionization, are of intrinsic interest and are critical for the design of future probes to study the ice grain plume around Enceladus. Measurements of the scattering dynamics of ∼700 nm diameter pure water ice grains upon 0.2–2.4 km/s impact with a metal target are reported here. Production of these Enceladus plume grain analogues and their subsequent acceleration to controlled final velocities were performed with an aerosol impact spectrometer. The particle impact and various impact behaviors, including rebound, sticking, particle fragmentation, and impact ionization, were characterized as a function of velocity with an angle-resolved image-charge particle detector. The probability of rebound, sticking, and particle fragmentation was the highest below 400 m/s, between 400 and 800 m/s, and above 800 m/s, respectively. Impact ionization was also observed for impact velocities above 1000 m/s.

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.
