My thesis work is focused on understanding the magnetic properties of the interstellar medium (ISM) within our Galaxy. In particular, I am interested in understanding how the Galactic magnetic field connects between different phases and spatial scales within the ISM. I am also interested in interstellar extinction in star forming regions where the ISM is primarily molecular. To do this, I am using optical and infrared photometry to study stellar extinction curves within a nearby giant molecular cloud with the goal of more accurately characterizing the ISM dust properties.
I study the formation of planets, their interiors and planetary orbital dynamics. My goal is to determine how formation and orbital interactions influence the population of rocky exoplanets in terms of orbital and physical properties. I am also interested in the implications of these findings on exoplanet habitability. I depend primarily on numerical simulations of orbital dynamics and planetary interiors with the occasional use of observations of solar system and extra-solar bodies.
I am primarily interested in using a combination of simulations, statistics and observations to answer questions about our Universe. Recently, I have used strong gravitational lensing and Bayesian inference techniques to constrain ultra-light dark matter theories. I have also worked on 21cm cosmology, from a theoretical and experimental perspective. For instance, I have investigated the effect of spin temperature on the relationship between matter and ionized hydrogen during the Epoch of Reionization with MCMC methods.
I was born and raised in Shanghai, China. I received my bachelor degree in astronomy at the University of Science and Technology of China (USTC). My research interests cover a wide range but focus on galaxies. In my spare time, you can see me playing badminton/swimming/jogging. I enjoy traveling in different countries and visiting museums.
Early universe cosmology, inflation, cosmic microwave background, gravitational waves
I use simulations to study gravitational waves signals from inflation and forecasting for the CMB satellite LiteBIRD. I believe it is very important to increase the visibility of minoritized groups, increase diversity, and help make academia a more welcoming and accepting place. Alongside my research, I am also very engaged with public outreach in order to promote enthusiasm for science in youth and advocate for diversity.
Anna O’Grady is a sixth year PhD candidate who studies massive star evolution, with a particular focus on variable and transient behaviour in supernova progenitors. She is supervised by Dr. Bryan Gaensler and Dr. Maria Drout. Her research involves identifying/analyzing the parameters of large populations of evolved massive stars in nearby galaxies, such as the Magellanic Clouds.
Supervisors: Chris Matzner + Peter MartinInterstellar medium, early stages of star formation, working with observational data of star forming regions from Herschel Space Observatory and Dragonfly telescope.
Currently a first year PhD student, I obtained my BSc in Earth Science (Geophysics specialization) from University of Waterloo in 2015. Afterwards, I briefly worked in engineering consulting before spending several years working in tech, and am now happily dedicated to my passion for astrophysics.
