She has served as a member of the Scientific Committee of the International Global Atmospheric of Chemistry (IGAC) for the period 2003-2009, and as a member of the international Commission for Atmospheric Chemistry and Global Pollution (iCACGP) since 2006. In 2010 she was elected as vice-president for iCACGP, and in 2015 she was elected as vice-president for the International Association of Meteorology and Atmospheric Sciences (IAMAS). Also, she serves in the Scientific Steering Committee of the Surface Ocean Land Atmosphere Studies (SOLAS).

She teaches courses on atmospheric chemistry, modeling and global change, inverse modeling, atmospheric science and introductory physics at University of Chile. She has guided multiple theses in engineering and atmospheric science in Chile. Roughly half of her students have followed research programs and scientific careers abroad. All in all, she has made original scientific contributions, and played a significant role in establishing atmospheric chemistry and modeling in her home country and internationally. Dr. Gallardo (Research ID H-4370-2013) shows a vast international collaboration network, and her work is cited worldwide.
