Dr. Kunio Sayanagi

Assistant Professor

Dr. Sayanagi earned his B.S. in Liberal Arts with emphases in Physics and Applied Math from Juniata College in Huntingdon, PA, and M.S. and Ph.D. in Physics from the University of Arizona, in Tucson, AZ.  Before arriving Hampton University, he held research positions at the University of Louisville in Louisville, KY, California Institute of Technology in Pasadena, CA, and the University of California Los Angeles in Los Angeles, CA.  He has also served as a panelist on the 2009-2011 Planetary Decadal Survey by the National Research Council of the United States National Academies, and made recommendations to NASA and NSF on the planetary science research priorities in the 2013-2012 decadal period.  He has also participated in the planning of the joint NASA-ESA Europa-Jupiter System Mission.

Teaching Experience: Teaching Assistant, Physics, University of Arizona 2001: Taught two introductory physics laboratory course sections, Teaching Assistant, Astronomy, Juniata College 1997-2000: Ran Observation sessions for introductory astronomy class

Research Interests: Dr. Sayanagi's research interests encompass a wide range of topics in planetary atmospheres.  His research activities can be categorized into three rough areas. First, he studies atmospheric dynamic phenomena by numerically modeling atmospheric features such as jetstreams, vortices and waves. Second, he analyzes images returned from space probes to analyze clouds; in particular, he analyzes the images returned from NASA's Cassini spacecraft to study the motions and properties of clouds on Saturn. Third, he develops measurement methods and image processing techniques to improve and enable new analysis of images returned from space missions.
