Jeffrey T Roberts is the Distinguished McKnight University Professor and Chair of Chemical Physics at the University of Minnesota. The Roberts Group studies surface chemistry at nanometer-sized aerosol particles. The problems studied have applications in a broad range of fields, from the atmospheric sciences to materials chemistry.

Roberts multi-disciplinary work venters on studying chemistry at complex interfaces. For example, looking at a stream of soot particles being emitted into the atmosphere. Where do those particles go? What role do they have in the chemistry of the atmosphere? The group is also exploring how a plasma reactor (used to grow silicon nanoparticles), asking: How can science manipulate the surfaces of those particles to make them stable for device applications?

The Roberts Group projects fall into two areas:
  1. Understanding the reactivity of nanometer-sized atmospheric aerosol particles, such as soot, and
  2. Developing new ways to deposit materials that have applications in the microelectronics industry.
The work also involves collaborations with scientists and engineers across the University of Minnesota, including Prof. Wayne Gladfelter in the Chemistry Department, Profs. Steve Girshick and Uwe Kortshagen in the Mechanical Engineering Department, and Prof. Stephen Campbell in the Electrical and Computer Engineering Department.
