Research in the Sadighi group focuses on the design and synthesis of late transition metal complexes in unusual coordination environments and oxidation states. We are particularly interested in the synthesis of small clusters of low-coordinate late transition metals, with the goal of achieving difficult bond-forming and bond-breaking processes to develop new catalytic cycles.  Metal–metal interactions represent an important aspect of these clusters, with implications for cooperative substrate activation and for multielectron reactions. 

Catalytic reactions of interest include the transformation of carbon dioxide to liquid fuels.  This field has seen remarkable recent advances, but important opportunities and challenges remain. These challenges are complementary to the development of renewable energy: A conversion of CO2 to chemical fuel could make CO2 a currency, rather than a waste product, of energy use.  Another area of interest is the reaction chemistry of labile metal fluorides in carbon–fluorine bond-forming reactions.  Finally, low-valent late metal clusters show promise in key steps of aerobic oxidation catalysis, with potential industrial and environmental importance.

Randall Guensler is a Professor in the School of Civil and Environmental Engineering at the Georgia Institute of Technology. After working for the California Air Resources Board for seven years, and completing his Ph.D. in Civil Engineering at the University of California at Davis, Dr. Guensler joined Georgia Tech in 1994. During his years with the State of California, Dr. Guensler worked for four years in Compliance Assistance and for three years in the Executive Office, evaluating the design and implementation of transportation control measures by regional air quality management agencies. Since arriving at Georgia Tech, Dr. Guensler's main research focus has been the development of new monitoring and modeling tools to assess the air quality impacts of transportation policies. Dr. Guensler was the Chairman of the Transportation Research Board committee on Transportation and Air Quality from 1997 to 2002. From 1995 to 2001, Dr. Guensler served on the Environmental Protection Agency's Mobile Source Technical Advisory Subcommittee. Over the past ten years, he has served on various National Academy of Sciences committees and panels charged with the assessment of vehicle emissions impacts and identification of research needs. Dr. Guensler is the director of Commute Atlanta, a $2.3 million joint value pricing initiative sponsored by the Federal Highway Administration and Georgia Department of Transportation. Commute Atlanta includes the collection and analysis of second-by-second vehicle speed, position, and engine operating data from 470 vehicles in representative Atlanta households. The researchers have monitored more than 1.4 million vehicle trips (more than 350,000 vehicle-miles per month). In 2005, the Commute Atlanta households began participating in road pricing experiments (cent/mile pricing, as well as real-time congestion pricing). Dr. Guensler's research team is assessing consumer response to these pricing mechanisms. A secondary focus of the research is the enhancement of monitoring technologies and services to support future transportation planning, safety, and operations policy initiatives. Development of tools for data management, data analysis, and privacy protection became major research activities. Secondary research has also included analysis of speeding, journey to work route choice, trip chaining, activity-based demand, household tripmaking variability, household and vehicle range of travel, long-distance travel, freeway operations, engine load, start and soak distributions, transit bus operations, etc.
