Teaching and supervision

At the moment, I supervise undergraduate research projects and co-supervise PhD students.

Previously, I have been a teacher on the Queen Mary U. of London courses
Physical Cosmology (spring 2018)
Mathematical Techniques 2 (spring 2017)

and on the U. Helsinki courses
General Relativity (spring 2016)
Analytical Mechanics (fall 2015)
Cosmology I-II (fall 2014)
Mathematical Methods I-II (falls 2011-2013)
Radiation fields and Photons (spring 2013)
Thermophysics (falls 2011 and 2012)
Waves and fields (spring 2012)
Electrodynamics (spring 2011)


A workshop I'm organizing in London, UK, in March 2020: Novel astrophysical probes of dark matter

My PhD Thesis Cosmological Constraints on Higgs Portal Dark Matter

My Master's Thesis Epägaussisuudet kurvatonimallissa ("Non-Gaussianities in the curvaton model")
