**Position: **Senior Rearch Scientist

**Biography**

John Mallick joined CEM in 2012 as a Senior Research Scientist; his research interests lie in the field of low frequency electromagnetic and electromechanical design, analysis, and simulation and electrical power system modeling.

From 2001 to 2012 Dr. Mallick was a Senior Research Scientist with the Institute for Advanced Technology, where he developed analysis and simulation tools for pulsed power systems with an emphasis on modeling of pulse discharge rotating machines and associated control circuitry. He also developed electromagnetic analysis techniques for railgun launch phenomena. In 2008 he co-chaired the IEEE Electromagnetic Launch Conference held in Victoria, Canada.

From 1979 to 2001 Dr. Mallick was an Electrical Engineer with the GE Corporate Research and Development Center (Schenectady, NY) where he worked on a wide range of research projects, including:

- Development of finite element analysis tools for electromagnetic analysis of a AC, DC, and permanent magnet electrical machines.
- Design and fabrication of a mixed analog-digital integrated circuit for the control of low-voltage molded case circuit breakers.
- Design and construction of a superconducting DC-SQUID system for detection of cardiac biomagnetic signals, and the development of analysis codes for magnetic source localization.
- Development of tools and techniques for electromagnetic interference characterization of power electronic circuits.
- Development of advanced low-profile high frequency magnetic components for compact fluorescent lighting circuits.
- Development of RF coil systems for permanent magnet whole body MRI systems.

From 1986 to 1988 Dr. Mallick was an Associate Professor of Electrical Engineering at Union College (Schenectady, NY) where he developed and taught courses in electromagnetics, electric machines, circuit and system theory, and power electronics. During this time he also served as an in instructor in GE Power Systems Engineering Course offered by the GE Utility Systems Engineering Department to an international audience of utility engineers.

From 1989 to 1989 Dr. Mallick was Senior Principal Engineer for the Superior Electric Company (Bristol, CT) where he developed simulation and modeling codes for switched reluctance actuators for electric power steering systems, and developed optimization methods for the design of magnetoresistive rotary sensors.
