Research interests
I am a Postdoctoral Research Assistant in Radio/Millimetre Studies of Star Formation at the University of Leeds. I study the formation of high-mass stars using observations at infrared through radio wavelengths. In particular, I study the environment in which massive stars form and how this environment is affected by the development of an HII region (a region of hot ionized gas) due to the UV radiation they produce. At the University of Leeds I am a team member on the e-MERLIN Legacy Programme "Feedback Processes in Massive Star Formation", to observe the ionized gas from forming massive stars at high resolution. I have a particular interest in high-resolution observations at mm wavelengths to resolve discs around massive stars, and have led a team that found the first Keplerian-like disc around a forming O-type star. I am also interested in how star formation may be different near the centre of our Galaxy, and have studied the massive but apparently quiescent infrared dark cloud G0.253+0.016.

Student education
Since 2014 I have jointly supervised masters students in their final year projects, as well as supervised student summer projects. I also currently lead and demonstrate advanced labs for masters students.
