Robert L. Riemer joined the staff of the Board on Physics and Astronomy in January 1985. Dr. Riemer served as study director for the 1991 and 2000 decadal surveys of astronomy and astrophysics and with many other NRC committees, including committees on physics, aeronautics, space, mathematics, and interdisciplinary research. He received a B.S. with honors in physics and astrophysics from the University of Wisconsin-Madison and a Ph.D. with honors in physics from the University of Kansas-Lawrence for research in experimental high-energy physics.


Caryn Joy Knutsen is currently a program associate with the NRC’s Board on Physics and Astronomy. She came to the BPA in 2006 as a senior program assistant after completing a B.S. in mathematics from the University of Colorado at Colorado Springs in 2006. While attending the University of Colorado at Colorado Springs she also earned two certificates in industrial mathematics (levels 1 and 2). At the BPA, she operates in various administrative and supporting roles for multiple committees, and in January 2008 she received the “Rookie” award from the NRC’s Division on Engineering and Physical Sciences. She is a member of the Society of Industrial and Applied Mathematics.
