I earned my PhD in Physics in 2009 from the Complutense University of Madrid (UCM). I was a postdoctoral fellow in the Astronomy Institute of the National Autonomous University of Mexico (IA-UNAM), the Materials Science Institute of Madrid (ICMM-CSIC), and the Fundamental Physics Institute (IFF-CSIC). Currently, I am a postdoc in the Astrobiology Center. I study circumstellar envelopes of evolved stars, in particular of AGBs, RSGs, and PPNe. My works are mostly based on the analysis of single-dish and interferometer observations of molecular lines with different spatial resolutions carried out in the millimeter, infrared (mid and near), and visible wavelength ranges. I am an expert on high spectral resolution observations (R>50,000) and rotational and vibrational molecular spectroscopy. I frequently use single-dish telescopes such as SOFIA and the IRTF in the infrared together with the EXES and TEXES spectrographs and the IRAM 30m telescope in the millimeter, and interferometers such as ALMA. An important part of my work requires modeling of the emission of dust and molecules from the observed circumstellar envelopes in order to determine the physical, chemical, excitation conditions in the emitting regions.
