Welcome to my personal website. Here you will find my Curriculum Vitae as well as links to some of my other stuff.
I am currently employed as a PostDoc at Roskilde University, where I am part of the PandemiX research group, investigating historical pandemics and the COVID-19 pandemic.
Read more about PandemiX here.
In my Ph.D. I worked with mathematical modelling of MPNs, as part of the Cancitis Research Group.

Interactive figure of viral load (COVID-19)
2022
Heatmap comparing the number of new hospitalizations due to COVID-19 in different age-groups, depending on vaccination-status. Shows the number of hospitalizations per 100,000 citizens in each age-group, including the raw numbers. When I made the figure, the public focus was about the number of new hospitalizations, without regard for the size of the corresponding population-group in general (As an example, week 46 had 80 hospitalizations among vaccinated 80+-year old, with "only" 13 among the unvaccinated in same age-group. Relative to the population-groups however, the unvaccinated where three times as likely to be hospitalized).
2022
Supplementary figure to the heatmap, illustrating the number of new hospitalizations and hospitalizations per 100,000 for a specific week. To illustrate the main point, I also illustrated the proportion of hospitalization of 20-29 year olds as dots representing 5% of the population-group.
2022
Illustration of the progression of a naive calculation of the COVID-19 case-fatality rate (CFR) for Denmark from the start of the pandemic until April 2022. The figure shows how CFR declines as the vulnerable are vaccinated, increases as the Delta-variant dominates, and then again declines as booster-vaccinations are carried out and the Omicron variant dominates. Inspired by a similar figure for the UK created by John Burn-Murdoch.
2022
Development of educational material with the purpose of student-recruitment for the educations at Roskilde University, consisting of a short article, a worksheet and a video.

2021
Interactive figures showing model-calculations of the COVID-19 wave in Denmark during the summer of 2021. Increased vaccine-uptake and reduced sociatal infection meant that COVID-19 was dying out. The arrival of the Delta- and Omicron-variants meant that later COVID-19 waves occured at the end of 2021.

2021
Illustration of the viral load of an individual following a COVID-19 infection, and different testing strategies. The figure illustrates how frequent tests with a less sensitive test (e.g. lateral flow tests) can be better at detecting infections when compared to less frequent tests with a higher sensitivity (e.g. PCR-tests). Developed as part of PandemiX's modelling support of governmental investigation before the roll-out of the massive Danish COVID-19 lateral-flow testing strategy at the beginning of 2021.

2021
Decreasing COVID-19 infections following Christmas 2020/2021 and the arrival of the B.1.1.7 variant (later named Alpha), meant that, despite decreasing infections, an increase could be expected within a couple of weeks. Prediction made around week 5, and ended up being accurate for the following weeks.

The SIR-model is a classic model within epidemiology, and one of the mathematical arguments behind the COVID-19 lockdown in March 2020.
During the COVID-19 pandemic, I made a number of interactive visualizations of the SIR-model for make it easier for laypersons to get an intuitive understnaindg of how the model works, and the model parameters.

2016 and 2017
Long before COVID-19 made disease-spread and epidemiology common terms, I worked with mathematical epidemiology as a student. During my education, I was part of the Science Show at Roskilde University, in which we made public dissemination of various student-projets in an effort to attract new student to Roskilde University. For the Science Show presentations, I developed an agent-based visualization of the SIR-model, to illustrate different epidemiological aspects.
