Hi, I’m Dr Hattie Stewart

I am a postdoc at the University of Bristol applying Machine Learning imaging techniques to astronomical datasets. My PhD research applied segmentation methods to radio continuum data from SKA precursor surveys to detect and characterise radio sources. I am now applying these techniques to explore new data reduction methods for observations of exoplanetary atmospheres with JWST.

I am interested in the concept of fundamental models in astronomy: what do they look like, can/should we develop them and how do we go about it?
