Jim works in the field of sustainable aviation as a principal research engineer within the Department of Aeronautics and Astronautics at the Massachusetts Institute of Technology. He is the Associate Director for the Partnership for AiR Transportation Noise and Emissions Reduction (PARTNER), a leading aviation cooperative research organization, and an FAA/NASA/Transport Canada-sponsored Center of Excellence. His work focuses on mitigating the environmental impacts of aviation through alternative fuels for aviation, aircraft design, and operations.

Alternative Fuels for Aviation:

Jim is leading research sponsored by the FAA, AFRL, and TRB to quantify the potential of alternative fuels to reduce the life cycle environmental impact of aviation. The life cycle of a fuel encompasses recovery and transportation of the feedstock to the production facility, processing of these materials into fuels, transportation and distribution of the fuel to the aircraft tank, and finally, the combustion of the fuel in the aircraft. The research has been focused on fuels that are compatible with today’s fleet of aircraft. Within PARTNER Project 17, the technical feasibility of alternative fuels was evaluated while PARTNER Project 28 focuses on environmental and economic feasibility of alternative fuels. ACRP 02-07 considered the feasibility of alternative fuels from the airport perspective.

Aircraft Design for the Environment:

Jim was co-chief engineer for the Silent Aircraft Initiative, a collaboration between Massachusetts Institute of Technology and Cambridge University. The Silent Aircraft project had the bold aim of discovering ways to reduce aircraft noise dramatically, to the point where it would be virtually unnoticeable to people outside the airport perimeter in a typical built-up area. He has followed up the work of the Silent Aircraft Initiative by participating in a NASA-sponsored N+3 project wherein he worked with a team to design Hybrid Wing Body aircraft for fuel efficiency, low noise, and reduced emissions. This work is considering both conventional jet fuel and cryogenic methane as the fuel for the aircraft.

Fundamental Research on Jet Noise:

Jim received his Ph.D. in Mechanical Engineering from The Ohio State University in 2004. His dissertation focused on the generation of noise by large turbulence structures within a high-speed jet. The experiments presented therein show the intimate relationship between the dynamics of turbulence and the creation of sound. His work is the first to visualize the time evolution of large turbulence during the creation of sound within a high Reynolds number, high-speed jet. This research was conducted at the Gas Dynamics and Turbulence Laboratory.
