Research Interests

My research is split into three main topics: (magneto-)hydrodynamic simulations of filament formation, evolution and fragmentation to determine how their role in the star formation process; the production of synthetic observations and techniques to better compare and interpret observations and simulations; and observations of continuum and molecular line emission of giant molecular filaments to study their kinematics and fragmentation. I am also interested in larger-scale problems such as the formation of molecular clouds and the effects of the supernova-driven bubble-dominated ISM on dense molecular gas, as well as smaller-scale problems such as core fragmentation, outflow jets, and core chemistry. A greater aim of my work is to better connect the physics on these multiple scales, via both observations and theory, to better understand how each scale influences the others and the resulting star formation.
