Matthew S. Hunt, PhD
Role in the KNI
Matthew Hunt is the Assistant Director of Staff Research and Lead Microscopist for The Kavli Nanoscience Institute (KNI) at the California Institute of Technology. He directs research projects that are carried out by KNI technical staff, in collaboration with Caltech & non-Caltech PIs and student researchers, with the purpose of creating new nanofabrication techniques using the KNI's leading edge instrumentation. He leads the scientific side of the KNI SURF-the-WAVE Fellowships Program, which offers summer fellowships to non-Caltech undergraduate researchers, and also leads the Lab Resident Expert Program, which provides top lab users an opportunity to give back to the lab in the form of process recipe development and new ideas for general lab improvement. Matt also manages – and teaches users how to operate – the KNI's suite of microscopy equipment: transmission electron microscopes, scanning electron microscopes, focused ion beam systems, an atomic force microscope, and related sample preparation equipment.
Matt joined the KNI in 2014 after completing his PhD related to the high temperature oxidation of turbine engine materials, through which he developed expertise in a number of electron, ion and x-ray microscopy techniques. His research interests lie in the development of new lithography and microscopy techniques that utilize various beam species (e.g. helium ions, neon ions, gallium ions, electrons) and the application thereof to the kinds of novel materials and devices that are important to users of the KNI.
Matt received his Ph.D. and M.S. in Materials Science & Engineering from the University of California, Irvine and a B.S. in Chemical Engineering from the University of Notre Dame.
