I'm a Researcher in the Department of Mathematics at Uppsala University, specialising in geometric analysis, particularly when applied to problems coming from general relativity. I am particularly interested geometric inequalities and the problem of quasi-local mass.
Anyone interested in learning more about the geometric or analytic aspects of general relativity, feel free to drop me an email. I'm always happy to chat!
My specialisation is geometric analysis, however most of my research is focused on problems coming from general relativity. I am particularly interested in the problem of quasi-local mass (hence the registration of the domain quasilocal.com), which amounts to determining a measure of the total mass or energy containing in a region of finite extend in some spacetime. Tangentially related to this, I am also interested in geometric inequalities analgous to isoperimetric-type inequalities, motivated by physical considerations via general relativity.

I am more than happy to discuss project possibilities with current and prospective students, both in relation to studying at Uppsala or abroad. You can write me an email with any questions. Here is some information for prospective students at each level, who wish to study in Uppsala:
At Uppsala University PhD candidates are considered employees, as is the norm in Sweden. This means that the recruitment process is similar to recruitment of other research staff, making the positions as competetive as they are attractive. When positions are available, they are advertised here.
Information regarding the Master's Programme in Mathematics at Uppsala University can be found here.
There are also several scholarships available for international students, which can be found here.
I am available for supervision of Master's projects. Contact me if you are interested and I can provide some suggestions for project topics.
For current Bachelor's students in mathematics or physics at Uppsala, I am available to supervise Bachelor's theses. Contact me to discuss potential projects.
