About me

My webpage (which also hosts all published models) is still hosted at QUB, please follow this link.

I am a tenured researcher (equivalent to Associate Professor) at Stockholm University since 2019. This is where I once started my research career (PhD degree in 2011), and in between I've had post-doc stops at Queen's University Belfast (2012-2015) and Max-Planck-Institute for Astrophysics in Garching (Marie Curie fellow 2016-2019). I currently hold an ERC Starting Grant, Swedish National Research Council Establishment Grant, Swedish National Spaceboard Grant, and a KAW project grant (the last together with S. Rosswog, J. Sollerman, A. Goobar and H. Peiris).

My research concerns the development and application of spectral models for supernovae (massive star explosions) and kilonovae (neutron star mergers). Our group in particular focuses on trying to understand how emission lines in these rapidly expanding nebulae form, and how such lines can be used to determine the nucleosynthesis production and put constraints on the origin and explosion physics of SNe and KNe. I have developed the spectral synthesis tool SUMO which has been extensively used to model spectra from H-rich SNe, stripped-envelope SNe, pair-instability explosions, superluminous supernovae, and Type Ia supernovae. In 2020 I led a paper published in Science where we identified emission lines never seen before in a supernova and showed how thia revealed something very unexpected about the origin of bright Type IIn supernovae.

 

My research group currently consists of post-doc Sofie Liljegren (modelling chemistry in supernovae) and PhD student Quentin Pognan (kilonova modelling). Recruitment of 2 new PhDs and 4-5 postdocs are anticipated in the coming 1-2 years.
