I am a PhD student working with Prof. Rene Oudmaijer on the study of Massive Young Stellar Objects (MYSOs). My project involves combining high-resolution observations from the Very Large Telescope (VLT) and multi-wavelength data from the Red MSX Source (RMS) Survey with 3D radiative transfer models to study the protostellar environments of MYSOs. The specific VLT instruments I have worked with are the mid-infrared interferometer, MIDI, and the VLT Imager and Spectrometer for the mid-infrared, VISIR. One model is to be fit to each of the three observational datasets simultaneously, allowing us to better constrain the characteristics and properties of the massive protostellar environment. The overall aim is to perform this analysis for a sample of over 20 MYSOs and to identify any trends that exist between them. My project was awarded a grant from the European Southern Observatory's (ESO) Director General Discretionary Fund, through which I was able to work with collaborator Willem-Jan de Wit at the ESO Santiago office on interferometric data from the VLTI. I have also been lucky enough to collaborate with Peter Tuthill and Barnaby Norris at the University of Sydney, where I worked with sparse-aperture masking (SAM) data with the aim of using it to study MYSOs.

In addition to my main project, I am a demonstrator for the first year undergraduate laboratory modules, a first-aider, and a member of the postgraudate advisory board.
