Department Chair

Brian Beecken

Department Chair and Professor of Physics and Engineering | beebri@bethel.edu | Started at Bethel: 1988

Dr. Beecken received his M.S. and Ph.D. in physics from the University of Minnesota and then spent 2 years on the engineering technical staff at Texas Instruments. One of his research interests is modeling the charging of dielectrics on spacecraft, and he has collaborated with both NASA's Jet Propulsion Laboratory (JPL) and the Air Force Research Lab in Boston and Albuquerque. Other research interests are optical detectors, including work on infrared detector limitations at Arnold Engineeri. . . read more.


Thomas Greenlee

Professor of Physics | gretom@bethel.edu | Started at Bethel: 1979

Dr. Greenlee received his M.S. and Ph.D. degrees in physics from the California Institute of Technology. His doctoral dissertation was in experimental atomic spectroscopy applied to the determination of the solar abundance of manganese. Since coming to Bethel, he has had grants from 3M for laser interferometry to measure roughness of surfaces and temperatures of gases. In 1993 and 1994, Dr. Greenlee was awarded a summer research fellowship in temperature measurement by infrared pyrometry at. . . read more.

Alyssa Hamre

Instructor in Physics | akh46956@bethel.edu | Started at Bethel: 2012

Prof. Hamre is passionate about teaching, including focusing on the exploration of new physics teaching methodology and doing some work in physics education research. Prior research focused on space plasma physics with a focus on the energy processes associated with the Northern Lights. She co-leads the Society for Physics Students group and she heads the Women in Physics & Engineering Club for the department.

Julie Hogan

Assistant Professor of Physics | juh82678@bethel.edu | Started at Bethel: 2017

Dr. Hogan is fascinated by fundamental particles, high energy phenomena, and the mysteries they can answer about the universe. She received her M.S. and Ph.D. in physics from Rice University. Her dissertation sought to confirm or disfavor hints of new physics at the Fermilab Tevatron’s D-Zero experiment by precisely measuring the forward-backward production asymmetry of bottom quarks. Since 2015, she has done postdoctoral research as a member of the Compact Muon Solenoid experiment, situa. . . read more.

Chad Hoyt

Associate Professor of Physics | hoycha@bethel.edu | Started at Bethel: 2006

Dr. Hoyt received his Ph.D. with distinction in optical science from the University of New Mexico in 2003. His dissertation comprised some of the first observations of laser cooling in solids, for which he was awarded a $10,000 prize by the Optical Society of America and New Focus, Inc. He earned an award for outstanding laboratory mentorship of undergraduates in PURSUE, a NASA-funded program that encourages under-represented people in science. After completing his Ph.D., Chad won a post-d. . . read more.

Nathan Lindquist

Associate Professor of Physics | n-lindquist@bethel.edu | Started at Bethel: 2011

Dr. Lindquist received his M.S. in Physics and his Ph.D. in Electrical Engineering at the University of Minnesota. He also worked for several years developing optical biosensors at Medtronic, Inc. During graduate school and his time at Bethel, Dr. Lindquist has published or presented more than 70 papers as author or co-author, including in the prestigious journals Science, Nature Communications, and Nano Letters. His work has more than 1000 total citations and has been featured as several c. . . read more.

Richard Peterson

University Professor of Physics Emeritus | petric@bethel.edu | Started at Bethel: 1980

Dick Peterson received his Ph.D. in physics at Michigan State followed by postdoctoral and several summer VSM positions in optical plasma diagnostics in the Physics Division at Los Alamos. Since coming to Bethel University, he has worked with students in developing new methods for fast interferometric and holographic measurements of all sorts. He has received the American Physical Society's (APS) prize for outstanding research at an undergraduate school and was elected a Fellow of the APS i. . . read more.

Karen Rogers

Associate Professor of Engineering | kir53855@bethel.edu | Started at Bethel: 2017

Dr. Rogers received her bachelor’s degree in Electrical Engineering from the General Motors Institute in Flint, Michigan, and her master’s degree and doctorate in Mechanical Engineering from the Massachusetts Institute of Technology. She has taught many undergraduate courses in electrical and computer engineering during a 22-year teaching career at Kettering University in Flint, Michigan. For one and a half years of that time, she was the Interim Department Head for Electrical & Compute. . . read more.

Keith Stein

Professor of Physics | k-stein@bethel.edu | Started at Bethel: 2001

Research interests include student-faculty studies of supersonic flows and shock waves and Dr. Stein currently is the principal investigator on a $143,557 NSF grant for creating interactive videos on these phenomena.
