"Playing with lasers got me this far in life"
Before coming to Bethel to lead the AMO Lab, Dr. Lemke received his Ph.D. in Physics from the University of Colorado-Boulder. For his thesis he developed and characterized a laser-cooled atomic clock of extreme precision and repeatability. After postdocs at PTB (Germany) and the Argonne National Laboratory (Illinois), he was a staff scientist with the Air Force Research Laboratory in New Mexico. There Dr. Lemke designed and developed a portable atomic clock as well as methods for laser time transfer. He has authored over 30 papers in the areas of optical clocks, precision measurements, and laser development.
When not teaching or doing research, Dr. Lemke's main passions are engaging in environmentally-friendly farming practices on his family's Iowa Century Farms, and tormenting his 3 children.

University Professor Emeritus
Dick Peterson received a Ph.D. in physics at Michigan State followed by a postdoctoral position in optical plasma diagnostics at Los Alamos National Laboratory. He has worked with Bethel students in developing new methods for fast optical measurements and received the American Physical Society's (APS) national prize for research at an undergraduate school and was elected a Fellow of the APS in 2005. He was elected to serve in 2003-2007 within the Presidential track of the American Association of Physics Teachers (AAPT) and is a Fellow of the AAPT. In 2010 the Optical Society of America (OSA) recognized him as a Traveling Lecturer and Senior Member for professional work and service in optics and photonics. In 2006 he was appointed the first University Professor at Bethel for his research, teaching, and physics community service, and in 2011 he was elected to the MN Science and Technology Hall of Fame. He served from 2010 - 2012 in Arlington, VA as a Program Director within National Science Foundation's Div. of Undergraduate Education (DUE), and in 2017 he was awarded the J. F. Reichert prize by the APS for work with advanced U.S. physics teaching laboratories.
