Bio

I am a Postdoctoral Research Fellow in the Department of Physics (and the W. W. Hansen Experimental Physics Laboratory) at Stanford University, and a Mentor at the NASA Frontier Development Lab. My research interests are in the application of machine learning in heliophysics.

Prior to coming to Stanford, I completed my PhD at the University of Glasgow under the supervision of Dr Iain G. Hannah. My PhD research concentrated on one of the unsolved problems in Heliophysics—the coronal heating problem. During my PhD I gained expertise in numerous time-series analysis techniques and methods for recovering the differential emission measure (an ill-posed inverse problem) from a wide range of spectroscopic and narrowband data. I am a member of the NuSTAR heliophysics working group and I led the analysis of the first solar flare observed by the NuSTAR hard X-ray astrophysics imaging spectrometer. I have also developed a stellar flare detection algorithm based on the observations obtained by the Kepler space telescope to determine the superflare rate of the Sun.
