About me

Welcome to my homepage! I’m thrilled to share my journey as a PhD physics student at Queen’s University (host to the Arthur B. McDonald Canadian Astroparticle Physics Research Institute), where I’m actively engaged in groundbreaking research as part of the QHEAT group (Queen’s High Energy and Astroparticle Theory). Under the guidance of my esteemed supervisor, Joe Bramante, I delve into fascinating realms of scientific inquiry, exploring concepts ranging from next-generation dark matter detectors fueled by supperradiance to unraveling the mysteries of quark matter within neutron star cores and probing the depths of early universe cosmology. Currently, I’m extending my research horizons as a visiting researcher at Heidelberg University, collaborating with Joerg Jaeckel on innovative projects centered around axions and dark matter.

I earned my M.Sc. Physics degree from  Heidelberg University in Germany. For my master’s thesis, I performed research at McGill University in Canada as a graduate research trainee under the supervision of Katelin Schutz. My final thesis titled Axion Basinschein : A search for gravitationally bound solar axions via stimulated decay into photons, which you can find below under projects.

Before Heidelberg, I graduated with a B.Sc in Physics from Leipzig University in Germany. During my undergraduate years, I worked as a teaching assistant in Theoretical Physics, Mathematics, and Experimental Physics, totalling over 250 hours of undergraduate-level classroom teaching. My final bachelor’s thesis had the topic Black holes, Singularity theorems and the Global Structure of Spacetime.

The primary purpose of this website apart from who I am and what I have done is outreach. These past five-six years of my life revolved around one thing - Theoretical Physics. While on this incredible journey, there were numerous instances where I had the thought, “if only someone had told me that, I would have saved hours of work” or “that one statement made me understand XYZ.” I want to pass on the wisdom and tools I gained on this journey to my colleagues and anyone trying to decipher the breathtaking world of physics. You can check the “notes” and “literature” tabs. I am also thinking of starting a regular blog about things like my learning techniques, note-taking algorithms, paper-reading styles, etc. So keep an eye out for that.

I hope whoever found this website gains something valuable from it. If not, you just got acquainted with another friendly face :). Also, feel free to reach out using the contact at the bottom of the webpage. (As most academics, if I don’t reply after a week or two - don’t be shy to send a catch up) :D

IPSP Part 2 - Preparation phase FAQ.

If you have read part 1 of this blog, you know that everyone who meets the HEQ criteria in the eyes of Uni-assist gets accepted. Contrary to most good physics programs worldwide, the hard part is not getting accepted to IPSP - it’s survival.

IPSP Part 3 - I am here!! Let's make the best out of it.

Note: I am assuming that most of you have a high-school level of physics (that is up-to-date and not rusting for years altogether) and went through the foundational mathematical preparation in the IPSP II post.

Warning: I graduated from IPSP in 2019 and was a TA until March 2020. Afaik, nothing has changed “drastically” since I left Leipzig. If I get any updates, I will try to point them out every time I update this page.
