Dr. Peralta has a background in applied physics and electrical engineering, including a wide range of technical experience in the design and implementation of both hardware and software solutions to challenging problems.

Dr. Peralta’s expertise includes electromagnetic simulations of nanophotonic devices and nanofabrication techniques for microelectromechanical systems (MEMS). He has extensive experience with the design and construction of optical/laser systems and other experimental apparatus including high vacuum and RF systems for the control, manipulation, and detection of charged-particle beams. He has also built the necessary instrumentation for these systems, including software and user interfaces for data acquisition and analysis, automated measurement, and image/signal processing. His core programming capabilities are Matlab and LabVIEW, and he has experience with software packages Lumerical, ANSYS HFSS, COMSOL, and SolidWorks. 

At Exponent, his work focuses on failure analysis of consumer electronics, material characterization for product development, component failure investigation via X-ray Computed Tomography (CT), and digital signal processing. Prior to joining Exponent, Dr. Peralta’s graduate research focused on the design, fabrication, and demonstration of grating-based dielectric microstructures for laser-driven acceleration of electrons, more commonly referred to as a "particle accelerator on a chip." He published this work in the Nature magazine.
