Causation, Prediction, Explanation

Sociology is in upheaval: After machine learning technologies brought about huge changes in the area of engineering, social sciences are catching up, introducing more and more machine learning methods into their research. But is machine learning really the next big thing, or rather something additional that you may or may not use? In this blog post I focus on initial research questions that popped up after the first weeks of my PhD, and which will guide my work in the future.


Homecoming

After six weeks in Norrköping, and two weeks before Christmas, it is time for a first feedback. How is it to start a PhD in the mid of a global crisis?


Data Analysis with Python, VS Code and Jupyter

A big part of my PhD will consist of performing data analysis, enhanced with machine learning techniques where appropriate. But before turning to methods such as Latent Dirichlet Allocation (LDA), Word Embeddings, or even model-based classifiers ("neural networks"), it is time to set up my data analysis toolchain again. I have been using Jupyter with VS Code for a few years now, and in this article I explain how you can do the same.


Computational Sociology

One month of Analytical Sociology, and I'm getting comfortable in the field. In this post, I outline what I've so far learned about Analytical Sociology and Computational Social Science and who the players in the field are. And I encounter an old acquaintance …


Responsibility

A PhD is many things at once: an experience, an academic title, and an education, for example. But it also is a bearer of responsibility of a different quality than what your undergraduate studies would have you believe. In this article I want to share first thoughts on the kind of responsibility attached to a PhD.


Explainable Science

Two weeks into my PhD here at Linköping University, and I can finally shift to more "scientifically salient" blog posts. What this means? This post is all about what I learned within these two weeks on how to conduct testable, causal research.


First impressions of Norrköping

One week of Sweden – it's time to share the first impressions. The city is beautiful, and even though the sun sets at half past four, there's just enough sunlight to capture the stunning architecture around the river Motala.


New Roads

One large suitcase and a ticket to Stockholm: This is all I take with me to begin my PhD in Analytical Sociology at Linköpings Universitet. This article focuses on moving to a different country during a global pandemic, and the purpose of this very blog.
