Specializations and Research Interests
• Modeling of the near-Earth space environment. I have worked with and have developed many different models of the upper atmosphere and magnetosphere. Towards the beginning of my career, I worked with the Assimilative Model of Ionospheric Electrodynamics, which was developed at the National Center for Atmospheric Research (NCAR). I ended up rewriting the data processing codes and, eventually, the entire code. During my post doc, I worked on porting the TIEGCM, another NCAR model, to a Linux environment. After I moved to the University of Michigan, I worked with the BATSRUS model of the magnetosphere, and coupled this to the TIEGCM. I further created an ionospheric electrodynamics code for BATSRUS and created code to allow BATSRUS to be run off of realistic, ever-changing, boundary conditions. Finally, I have developed a Global Ionosphere Thermosphere Model (GITM), which is significantly more flexible than existing upper atmosphere models, such as the TIEGCM. This code has been ported over to work on Mars and Titan as well as Earth. The majority of the research grants that I currently have are to utilize GITM for studying different aspects of the near-Earth space environment.
• Ground-based instrumentation. At this time, I have active programs for ground-based magnetometers in Antarctica and Fabry-Perot Interferometers (FPIs) in North America. The Space Physics Reseach Laboratory has developed an autonomous, low-powered, data system that can be deployed in extreme conditions. We have used this platform to deploy six ground-based magnetometers to Antarctica. In addition, I have been working with collaborators outside of UM to install FPIs in a wide area across the continent. We have recently won a grant to start a network of these FPI systems.
• Small satellites. Working with Professor James Cutler, I have won a grant to launch a CubeSat called CADRE, which will measure the state of the upper atmosphere. In addition, I am the Mission Scientist for the CYGNSS, a NASA mission that is composed of eight small satellites that will measure the surface wind speed above the oceans. I am also working on many proposals to try to increase the number of CubeSats that UM is leading, two of which have been submitted and are awaiting reviews. Both of these focus on supplying the European QB50 mission four CubeSats. The largest proposal that I am working on is for a constellation of 40-48 CubeSats that would measure the dynamics of the upper atmosphere.
