To better understand these systems, new diagnostics need to be developed that quickly gather information on multiple modalities.\u0026nbsp; In particular, I am interested in how encoding mechanisms can be exploited to gather data rapidly and then decoded to elucidate multiple physical phenomena and implement advanced control.\u0026nbsp; Many mechanisms such as optical diffraction, coherent interference, and magnetic field superposition inherently contain encoding principles, which can be further enhanced with adaptive under-sampling, active feedback control and stochastic system identification algorithms.\u0026nbsp; In this talk, I describe several multi-modality diagnostic measurement methods and discuss their application to challenging environments.\u0026nbsp; These include: 1) Digital holography methods for encoding three-dimensional information on two-dimensional sensors, 2)\u0026nbsp;Hyperspectral imaging and adaptive under-sampling, and 3)\u0026nbsp;Remote high speed magnetic field sensing of temperature, vibration, and fluid vorticity.\u0026nbsp; \u0026nbsp;The talk will conclude with an overview of my vision for how multi-modality sensing and encoding can be utilized for advancing high speed magnetic\/optical diagnostics, bio-inspired perception, and miniaturized sensing for distributed state estimation and control.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EDr. Ellen Yi Chen Mazumdar \u003C\/strong\u003Eis currently a postdoctoral appointee at Sandia National Laboratories in the Diagnostic Science and Engineering group.\u0026nbsp; She received her B.S. and M.S. in mechanical engineering from Massachusetts Institute of Technology (MIT).\u0026nbsp;\u0026nbsp; In 2015, she received her Ph.D. in mechanical engineering from the MIT BioInstrumentation Laboratory under the guidance of Professor Ian W.
