Eva Wirström is part of the Radioastronomy and Astrophysics research group and has her office at Onsala Space Observaroty. Her research interests includes the physics and chemistry in the giant clouds of gas and dust forming stars and planetary systems in our galaxy, as well as the link between these and the emergence of life - astrochemistry and astrobiology. As assistant professor she focuses on interpreting data from the Herschel Space Observatory, which among other things observed the water content in different kinds of gas in our galaxy. One method she uses is to develop computer-based models of complex chemical networks under varying physical conditions.
