The Laboratory for Aviation and the Environment (LAE) is a unit of the Department of Aeronautics and Astronautics at the Massachusetts Institute of Technology. The mission of the lab is to advance our understanding of the environmental impacts of aviation, and to develop approaches to mitigate those impacts.

The leadership of the lab consists of faculty members and research scientists, supported by administrative professionals. The research team consists of the faculty members and research scientists, research assistants enrolled for the SM or PhD degree at MIT, post-doctoral research associates, research specialists, and occasional visiting scholars. Much of the research also involves collaboration with other labs/departments at MIT, and colleagues in other universities, government agencies, and industry.

LAE was started in 1992 by Prof. Ian A. Waitz, then known as the Aero-Environmental Research Laboratory. The lab has been co-host to the ASCENT Center of Excellence HQ since 2013, and hosted the PARTNER Center of Excellence HQ from 2003 until 2015.

LAE is led by Director Prof. Steven Barrett, Associate Director Dr. Raymond L. Speth, Executive Officer Dr. Florian Allroggen, and Principal Investigators Prof. Hamsa BalakrishnanProf. R. John HansmanDean Ian A. WaitzProf. Karen Wilcox, and Dr. Jayant S. Sabnis.
