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, VLT, JWST, and Gemini South), radio (Herschel, ALMA, 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.
