Dr Burr▒s primary interest are the landforms that result from fluid flow. Fluid flow includes flow by water that formed ancient rivers deposits on Mars, as well as flow in current rivers of liquid nitrogen on Titan, the largest moon of Saturn. Dr Burr also studies the deposits formed by the flow of air, or wind, on Mars and Titan. In addition, Dr. Burr studies lava flows on Mars and the tectonic landforms on icy satellites of the outer Solar System.

Dr. Emery applies the techniques of astronomical reflection and emission spectroscopy and spectrophotometry of primitive and icy bodies in the near- (0.8 to 5.0 microns) and mid-infrared (5 to 50 microns) to investigate the formation and evolution of the Solar System and the distribution of organic material. The Jupiter Trojan asteroids have been a strong focus of his research, and he also regularly observes Kuiper Belt objects, icy satellites, and other asteroid groups to understand the state of their surfaces as related to these topics. Along with telescopic observations, he contributes to Solar System exploration as a science team member on the OSIRIS-REx asteroid sample return mission, the Lucy Trojan asteroid flyby mission, and the NEO Surveyor Mission infrared telescope mission.
