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 imagin g 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.

I have now completed my PhD, which was supervised by Prof Lyndsay Fletcher, and am about to start a postdoctoral fellowship at NASA's Goddard Space Flight Center ( April 2017).
My research interests are in solar physics, particularly in energy and radiation transport through the solar atmosphere during solar flares. I have expertise in data analysis using both imaging and spectroscopic observations from the Hinode, IRIS and SDO spacecraft, as well as using the numerical codes RADYN and RH to simulate solar flares, and the radiation they produce. I am eager to use a combination of both observations and numerical simulations to better understand the processes involved in solar flares.
I am primarily interested in Solar flares which I investigate through RHESSI hard X-ray imaging and spectroscopy, multi-wavelength analysis, statistical surveys and numerical simulations. I also work on quiet Sun X-ray emission, the observations and possible emission mechanisms.
I am currently a postdoctoral research assistant and I am interested in solar flare physics.
My main areas of research are:
Solar flare UV/EUV line spectroscopy and deducing solar flare heated plasma/ion properties.
Solar flare X-ray emission and deducing the properties of solar flare accelerated electrons.

I'm working on ‘Semantic Resource Discovery for the Virtual Observatories' (aka ‘astronomical data management', or ‘astroinformatics', or some variant on that).
Recent projects (PI or Co-I):
My research has been mostly focused on the analysis of observational data of solar flares, investigating the properties of high-energy particles (through radio/microwave and X-rays data, and also computational simulations) and evolution of the flaring regions, mostly using ultraviolet/X-rays data. Currently, I am investigating the characteristics of the flaring chromosphere, through the analysis of multi-wavelength data, using computational flare models and evaluating the comparison of data vs. models.
Dr. Sargam Mulay obtained a Ph.D. in Solar Physics from the University of Cambridge, UK in 2018. She had an opportunity to work with Dr. Helen Mason and Dr. Giulio Del Zanna on the topic of solar active region jets. After completing PhD, she joined as a postdoc at the Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, India. She worked with Prof. Durgesh Tripathi for 1.5 years on sigmoid observations. Since 2019, she is a research assistant with Prof. Lyndsay Fletcher at the University of Glasgow, UK and she is working on spectroscopic observations of solar flares.

I am working with Prof. Lyndsay Fletcher on solar flares. We are currently looking at the behaviour of the chromosphere during flares, with a particular focus on the hydrogen Lyman lines.

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:
