Jordan Marajh

Currently I am a postgraduate researcher in the School of Mathematical Sciences at Queen Mary University of London in my 4th year. I am under the supervision of Prof. Juan A. Valiente Kroon.

My research interests lie in General Relativity, particularly where the analysis of PDEs and Conformal/Differential Geometry enter the picture.

I am also exploring machine learning methods for mathematical discovery in the context of Differential Geometry.

Fun stuff

I really enjoy playing Dungeons & Dragons and have played for over 8 years almost every week — even during a pandemic. I am an avid videogame enjoyer and used to stream games online, in particular I enjoy rhythm games such as Osu! and looter shooters like Destiny 2. I also watch (a lot of) anime.

I walk every day into the office (permitting I do not get soaked in the rain) for over an hour and a half in the morning. It gives me plenty of time to think after opening arXiv in the morning and starts my day right.
