Dr. Geronimo L. Villanueva is a Research Assistant Professor (Physics) at Catholic University of America, in residence at NASA Goddard Space Flight Center.
His main area of research is high-resolution molecular-spectroscopy of planetary and cometary atmospheres.
He is currently investigating the existence of biomarker gases on Mars and the formation of the Solar System using
high-resolution spectroscopy at infrared (NASA-IRTF, Keck-2, VLT, and Gemini South), radio (Herschel, APEX, GBT, HHSMT, CSO, JCMT, and KP12m) and X-rays/UV (NASA Swift) wavelengths.
Dr. Villanueva has participated in many projects at three space agencies, NASA, ESA and DLR,
with a broad range of research experience in planetary, cometary, atmospheric, Space and computational sciences.

Ph.D. thesis title: The High Resolution Spectrometer for SOFIA-GREAT: Instrumentation, Atmospheric Modeling and Observations.
Research summary: the research involved the complete design and development of a new high-resolution spectrometer (CTS) for the Stratospheric Observatory for Infrared Astronomy (SOFIA), and the development of a Martian GCM (General Circulation Model) -a fully non-linear, global and three-dimensional hydrodynamic model- for the study of the Martian atmosphere through the analysis of the forcing and tracing circulation of atmospheric chemical constituents. Both studies were complemented via observations of the temperature structure of the Martian atmosphere through analysis of fully resolved spectroscopic measurements of CO lines in the sub-millimeter using the new CTS.
2000 - 2001: Institute for Environmental Research (IEMA), Argentina.
Research summary: Development of a system to control and monitor a radiometric observatory, for ground-based microwave observations of stratospheric ozone and tropospheric water vapor.
Organizing Scientist of the MAS+ project "Reducing the Digital Divide in Argentina". This project, sponsored by Microsoft, provides training and access to the newest technologies to young students of public schools and universities. In 2006, Dr. Villanueva opened in collaboration with the National Technological University of Argentina and Microsoft a computer lab with 12 new computers, with an initial allocated budget of 1 million dollars. This laboratory is now being used to train students and teachers in ".Net" software technologies.
