Dana Longcope, Ph.D
B.S., Applied and Engineering Physics, 1986, Cornell University, Ithaca, NY Ph.D., Applied Physics, 1993, Cornell University, Ithaca, NY. Dr. Dana Longcope is an Associate Professor of Physics at Montana State University-Bozeman. He teaches Physics and conducts research, with both undergraduates and graduate students, in the area of Solar Physics. Dr. Longcope conducts theoretical research into the basic physics of magnetic fields in ionized plasmas and the application of these concepts to magnetic fields on the Sun. He has studied the storage and release of magnetic energy in the Sun's corona through a process known as reconnection. This kind of energy release is currently thought to occur in solar flares as well as smaller, less dramatic solar events called microflares and X-ray bright points. He has also studied the rise of slender strands of magnetic field from deep within the Sun up to the solar surface. The emergence of this rising flux leads to sunspots, and models of rise yields a better understanding of Sunspot characteristics. Dr. Longcope is a graduate of Cornell University (B.S. 1986, Ph.D. 1993), and did Post-Doctoral research at The Courant Institute of Mathematical Sciences (New York University) and the University of California, Berkeley. He arrived at Montana State University in 1996. Honors and awards include a Fellowship from the Miller Institute for Basic Research in Science (1993), a Faculty Early Career Development (CAREER) grant from the National Science Foundation (1997), the Presidential Early Career Award for Science and Engineering (2000), the Karen Harvey Prize from the Solar Physics Division of the American Astronomical Society (2003), and the Charles and Nora L. Wiley Award for Meritorious Research (2003) and the Cox Family Award for Creative Scholarship and Teaching (2006) both from Montana State University.
