Associate Professor
Sibley School of Mechanical and Aerospace Engineering


Douglas MacMartin is an Associate Professor in the Sibley School of Mechanical and Aerospace Engineering at Cornell University.  His research focuses on Sunlight Reflection Methods (SRM, also known as climate engineering, solar geoengineering, or climate intervention), with the aim of helping to develop the knowledge base necessary to support informed future societal decisions in this challenging and controversial field.  He has published extensively on the subject, and in addition to public and academic presentations has provided briefings to the UN Environment Program and testimony to the US Congress, and was a member of the US National Academies panel that made recommendations on both research and governance in March 2021. He received his Ph.D. in Aeronautics and Astronautics from MIT in 1992; previous positions include United Technologies Research Center (1994-2000) and the California Institute of Technology (2000-2015).  His research is funded by NSF and by the Cornell Atkinson Center for a Sustainable Future.

Research Interests

Dr. MacMartin works at the interface between engineering feedback analysis and climate dynamics, using tools from engineering dynamics and control to solve critical questions in climate science. Primary focus is on developing the knowledge needed to support informed decisions about solar geoengineering; mainly with stratospheric aerosol injection (SAI).  Interests also include dynamics and feedback analysis of the climate more generally.  Member of the systems engineering team for the Thirty Meter Telescope, involved in control design and dynamic performance analysis.  Previous research areas include vibration, noise, and flow control.
