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")

Longer articles, news, interviews, and videos of me and my research can be found in e.g. Gizmodo,, Medium, Youtube here and here, TSB Digest (in English),, Helsingin Sanomat, Suomen Kuvalehti, Suomen fyysikkoseuran blogi, Tähdet ja avaruus, Yle Areena, Yle Tiede, Yle Radio Suomi, Tekniikka ja talous (in Finnish) and Hufvudstadsbladet (in Swedish).
