Abstract　 　　 

　The talk will give a brief overview of the work carried out in our LERMA group at the Observatory of Paris. The group of about 150 people covers a wide range of subjects, ranging from cosmology and extragalactic astronomy, Galactic astronomy, molecular spectroscopy in space and in the laboratory to Earth remote sensing and instrumentation. The talk will only touch on the different subjects but not go into much detail. The objective of the talk is to give a general picture of the research activities and to introduce our group to you.
