I am a post-graduate research student, working on Cosmology with Prof. Erminia Calabrese since October 2020. Before this, I obtained both my Bachelor's and Master's degrees at Leiden University, graduating with my Master's thesis on an Effective Field Theory description of Multi-Field Inflation.

Within my PhD research, I am working with observations of the CMB by the Atacama Cosmology Telescope (ACT) and the Simons Observatory (SO) collaboration. Within these collaborations, I work on the pipeline for foreground extraction and cosmological parameter estimation.

I have recently written a WMAP likelihood and a Planck likelihood for combined experiments (i.e. ACT+WMAP, ACT+Planck, etc.).

Apart from cosmology, I am always interested in talking about linguistics, where my main interest lies in the languages of the Near East during the pre-Classical era (specifically Old-Persian, Ugaritic and Sumerian are a focus of my current studies).

I am very much interested in Cosmology, both from a theoretical and observational aspect.

I am currently working within the Simons Observatory (SO) collaboration and on the observations of the CMB by the Atacama Cosmology Telescope (ACT).
