Computer Course for the Elderly
Education Project, Buurtwerkkamer TOP, 2021
Together with Buurtwerkkamer TOP, I am organizing a computer course for elderly people in my neighbourhood in Utrecht. We will cover basic topics such as Microsoft Office, e-mail, and web browsing. Sometimes people without many digital skills can feel left out. The hope is that we will be able to give people the confidence to interact more with the online world. Want to know more about this project and how you can help out people in your neighbourhood? Feel free to get in touch!
Cybersecurity Escape Room With U-Talent
Research Project, Utrecht University, 2021
Together with a group of high school students we are building a cybersecurity escape room and using it to answer some interesting research questions regarding framing of security content. The project is part of the U-Talent programme, an initiative to provide talented high school students with the opportunity to get in touch with real scientists.
Medium Article on Python Street Map
Creative Project, Medium, 2021
I wrote some code to create a personalised street map in Python. Initially this was a gift idea, but I ended up also writing an article about it on Medium. You can find it here if you’re interested. Let me know if you like it!
Medium Article on Chi-Squared Distribution
Creative Project, Medium, 2022
A short article explaining the connection between the chi-squared distribution and the standard normal from a mathematical viewpoint. You can find it here. People responded really positively to it, so I’m planning to write more articles like this.
Elected to University Council
Work Project, Leiden University, 2022
On the 17th of May I was elected to the University Council of Leiden University. I will be one of the 8 employees representing our colleagues in the council. As a representative of PhDoc, I will focus my attention on the challenges for PhDs and postdocs at our university and how we can find creative solutions. I’m really looking forward to my term in the university council, which will run from September 2022 - August 2024 (± 10 hours per week).
Annual Agreement Report
Work Project, Leiden University, 2023
As part of my University Council work for PhDoc, I initiated an investigation into the use of annual agreements among early career academics at our university. Annual agreements provide employees with some flexibility regarding their holiday days, but have been criticised recently because they have many negative consequences, especially for early career academics. If you’re interested in improving working conditions at our universities, I hope you’ll take the time to read the full report. We discussed the report with the university board, who indicated they were grateful for our work and were going to implement changes to mitigate the issues with annual agreements.
