2016-present:
Director, Space Physics Research Laboratory (SPRL)/XTRM Labs
2009-2017:
Founding Director, Multidisciplinary Design Programs at the University of Michigan’s College of Engineering. In this role, he is working with a core team of committed faculty and staff to create an educational structure for significant, multidisciplinary design opportunities that engage students in real-world professional practice centered on design-build-test project activities. This initiative is part of an evolving vision for 21st Century engineering education at Michigan.
2006-2008:
Interim Chair, Electrical Engineering and Computer Science Department at Michigan (Interim Chair for Electrical and Computer Engineering in EECS, 2007-2008) (Associate Chair of the Electrical and Computer Engineering Division, 7/2004 – 6/2006). Under his leadership, the Department engaged in a major review of its organizational structure leading to new a leadership model for the Department and for its ECE and CSE Divisions which was then implemented during his tenure.
1991-Present:
Professor (Associate, 5/1997-5/2003; Assistant, 9/1991-5/1997) at The University of Michigan in Electrical Engineering and Computer Science (Radiation Laboratory) and the Atmospheric, Oceanic and Space Sciences Department (Space Physics Research Laboratory). Responsibilities include undergraduate and graduate education and research. His instructional emphasis is in the areas of electromagnetics, plasma electrodynamics, radiowave link design, systems design, and spacecraft design.
1989-1994:
Deputy Investigator (from 1991) and Program Manager (from 1990) for SETS. Responsibilities included: a) development and coordination of mission planning inputs to achieve SETS/TSS-1 science goals; b) science experiment design; c) overall management of SETS contractual responsibilities including flight hardware and mission support operations; and d) all decisions reflecting SETS relations with NASA and other TSS-1 teams. e) Led development of functional objectives to meet SETS science requirements for TSS-1 mission and their coordination with mission personnel. (1989-1990: Deputy Program Manager SETS)
1984-1991:
Graduate Research Assistant-Research was divided into two areas: a) investigations of electrodynamic effects due to electron beam and neutral gas emissions into a space plasma; and, b) radar and theoretical investigations of energetic electron beam generated artificial plasma density structures in the ionosphere using rockets and spacecraft including modeling of relativistic electron beam penetration into the atmosphere. Advisor: Professor Peter M. Banks
1978-1989:
Watkins-Johnson Company-Held both technical and supervisory positions associated with microwave integrated circuit and subsystem design for radar and ecm applications. Research activities included: phased array radar, low-noise amplifiers, phase-shifters, and microwave sample- and-hold circuits.
1977-1978:
Graduate Research Assistant in the University of Illinois Aeronomy Laboratory Rocket Program- Implemented a nighttime ionospheric electron density measurement experiment based on Faraday rotation, using a ground based HF transmitter and a rocket borne receiver. Advisor: Professor Leslie G. Smith
