United States Patent Application: 0100098599
As is typical, this United States Patent Application, which, despite it's rather anonymous title, concerns the use of solar energy to recycle Carbon Dioxide, doesn't identify the affiliations of the inventors.
However, web-based sources clearly disclose John Mankins to be the "Manager of Advanced Concepts Studies" at the NASA Headquarters Office of Space Flight; while, Robert Wegeng is a scientist at the USDOE's Pacific Northwest National Laboratory.
