I am working with Prof. Lyndsay Fletcher on the implementation of machine learning algorithms in solar observations. My main focus is on flare spectropolarimetry and how machine learning techniques can aid the data analysis process for carrying out chromospheric magnetic field diagnostics in a flaring atmosphere.

I have mainly applied supervised and unsupervised deep learning models to different solar aspects:

1. Deep convolutional neural network (CNN) for solar feature detection

2. Deep learning for correcting for atmospheric seeing in solar flare observations.

3. Invertible neural network (INN) for the inversion of solar flare line profiles.

A C.V. can be found here.

I conduct research focused on the observation and analysis of radio emissions from the Sun, under the supervision of Professor Eduard P. Kontar.  I am particularly interested in the physical mechanisms defining the morphological characteristics of Type II radio bursts which are excited by shock waves associated with Coronal Mass Ejections (CMEs).  I also study the radio-wave scattering effects in the solar corona to better understand the observed radio emissions.  I have utilised data from several instruments including SDO/AIA, SOHO/LASCO, GOES/XRS, and LOFAR.

I am a Carnegie Trust PhD student, working with Professor Lyndsay Fletcher and studying oscillations in the Sun’s atmosphere, with particular focus on the chromosphere. I use mostly ground based imaging spectro-polarimetry in conjunction with space based data to look for evidence of oscillations and pulsations during solar flare activity. I am also interested in chromospheric waves and oscillations in quiet conditions, such as sunspot oscillations.david

I am working with Dr Nicolas Labrosse. Our research is mainly concerned with solar prominences in the ultraviolet wavelengths. I am currently looking at data from SDO/AIA and IRIS analysing the evolution and spectra of the aforementioned solar phenomena.
