Research and Professional Interests

Dr. Larry Paxton has over thirty five years of leadership experience as a technical lead and as a line manager. He is currently the Head of the JHU/APL Geospace and Earth Science Group. As the Principal Investigator he has managed and led over $100M in projects. His experience includes: being PI or lead for five UV and one in situ instrument currently operating on orbit, with two more awaiting launch; development of novel instruments for low-cost space missions; climate disruption and its impacts on human society; multidimensional modeling of the upper atmosphere; database management; data visualization; project management; and support for national security missions. In addition to being the NASA GUVI instrument co-PI, DMSP SSUSI PI, SSUSI-Lite Pi, Cerebus PI, CANARY Project Scientist and GAIA PI Dr. Paxton has participated in the NASA Pioneer Venus, USN Remote Atmospheric and Ionospheric Detection System (RAIDS), USAF Visible Ultraviolet Experiment (VUE), SDIO Delta 180 and 181, and BMDO MSX spaceflight programs as well as the NASA SWUIS shuttle mission and two NASA sounding rockets. He also is the lead inventor for Patent No. 8,594,972 will issue on November 26, 2013 for an invention entitled “System and Method for Tomographic Retrieval of Parameter Profile from Traveling Path”. 

Dr. Paxton is a member of the American Geophysical Union, the American Meteorological Society (AMS), the American Institute for Aeronautics and Astronautics (AIAA), the International Academy of Astronautics (IAA) – Acadamician, and the American Astronomical Society Division of Planetary Sciences (DPS)
