Tishtrya Mehta


My PhD centres on using Empirical Mode Decomposition (EMD), amongst other techniques, to analyse subsurface behaviours of our Sun to better define properties of the Sun's magnetic dynamo. In particular I am analysing frequency shifts of pressure modes ( also known as p-modes; standing sound waves in the Sun generated by convective flows) observed by the GONG network over the past two solar cycles, which are affected by the presence of a magnetic field. I am supervised by Dr. Anne-Marie Broomhall, and am STFC funded.

I also take a keen interest in public engagement and improving access for minorities in STEM. If you are planning an outreach event, or want to discuss improving inclusion etc. feel free to get in touch!

Completed a Masters degree (MSci by Research), on investigating the behaviour of quasi-periodic pulsations (QPPs) in solar flares using Empirical Mode Decomposition (2017-18). Supervised by Prof. Valery Nakariakov.
