How to conference: 2 Golden rules for networking


5 minute read

Despite how others perceive me, I am actually quite shy. When faced with a room full of people, all huddled together in their little groups, chatting and having fun, I often find myself frozen and insecure. Who should I approach? How do I join a conversation? Where do I start?

The first conferences I ever attended as a doctorate student were IJCAI 2017 and CP 2017, which both took place in Melbourne. At the time, I had a position as a visiting researcher at ICTEAM at Université catholique de Louvain. After the conference, three fellow doctorate students from UC Louvain and I travelled to Tasmania, for a two-and-a-half-day trip. It resulted in one of my favourite travel stories of all time.

Introducing gismo: a tool for finding grouped independent supports


28 minute read

My first paper since joining Prof. Dr. Kuldeep Meel’s group at the National University of Singapore (NUS) has been accepted to IJCAI 2023! The topic of this paper was a completely new direction for me, and I learned a lot during this project. I had the great privilege to work with Kuldeep and with Prof. Dr. Arunabha Sen for Arizona State University (ASU) on this project, and learned a lot from each of them. In this blog post, I will share a bit about the problem that we solve, why it needs solving, and how we solve it, introducing our new tool: gismo.

Books that helped me through my doctorate

Two months ago, I defended my dissertation. I am very grateful to my advisors, my doctorate committee, my opposition committee, and my paranimphs. I thought long and hard about which thank-you presents would be appropriate and of value to them. In the end, I just decided to present them with some wisdom.

It takes a village

As a Master student, I once asked Siegfried if I should use ‘‘I’’ or ‘‘we’’ in my thesis. After all, the words were written by me, but we did the research together. He explained that, even if you are the sole author of a text, you should always write ‘‘we’’, because no piece of research ever is the product of just one person. I believed him then, but the experience of being a PhD candidate drove the lesson home, never to be forgotten. In this blog post, however, I am truly ‘‘I’’, and use it to thank those that make us ‘‘we’’.

Defence time for Jeroen

I am very proud of my student Jeroen Rook, who defended his Master thesis today! The title of his presentation was: Caching in Model Counters: A Journey through Space and Time. With a very general audience, Jeroen had his work cut out for him to explain not only his work, but also the basics of propositional model counting.
