Chris Bracken

Research Associate/Staff Engineer
University of Pittsburgh AMPED Laboratory

Biography

Chris received his B.S. in Electrical Engineering in the Circuits and Devices concentration from the University of Pittsburgh in 2015, as well as the Nanoscience and Engineering Certificate. Undergraduate work experience involved a Senior Design Project with Eaton and Undergraduate Research experience with Dr. Brian D’Urso’s Nanomaterials Research Group, being exposed to electronics design of a photodetector amplifier circuit for an optical trap and learning about growth and characterization of Graphene. Before joining the Ohodnicki Lab, Chris worked at Keystone Compliance, LLC and performed Electromagnetic Interference (EMI) tests for five years. Research interests include the Standardization of Electromagnetic Components and Material Measurements, Core Loss of Magnetic Components, and Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) of components and materials.

Dipika Mandal

Post-Doctoral Research Associate, Ferrite Magnetic Materials

Biography

Dipika received her M.Sc. in Physics from IIT Kanpur, India in 2015 following B.Sc. with Honors in Physics from University of Burdwan in 2013. She obtained Ph.D. degree in Physics (Experimental) from S. N. Bose National Centre for Basic Sciences, India in 2021, as a recipient of prestigious national fellowship from CSIR, India. During her Ph.D., she has extensively studied structural, frequency dependent dielectric and magnetic properties of transition metal-based ferrites focusing on their application in Electromagnetic Interference Shielding/ Microwave Absorption. She also has an expertise in synthesizing various complex nanostructures of ferrites as well as multiferroics. Currently, she is a Postdoctoral Researcher in Ohodnicki lab, University of Pittsburgh. Here her research interests orient on microwave processing technology development, measurement and analysis of microwave properties of materials, mainly ferrites, and their high-frequency applications.
