Writing a paper

I have mostly taken courses and done teaching during my Ph.D. so far. But this semester, I have focused on research. The idea is to use so-called multi-armed bandits to improve Brain-Computer Interfaces (BCI). Multi-armed bandits The challenge in a multi-armed bandit problem is to choose an action that gives you the highest reward. ForContinue reading “Writing a paper”

vBCI – reflections

I visited my first conference this spring. I presented a poster (abstract and video) for an adaptive approach to the calibration of BCI systems. I was very nervous before it started, but it was great – so much inspiration and new ideas. Some thoughts that I bring to the next conference I visit: Don’t be afraid toContinue reading “vBCI – reflections”

Summer BCI project

So far during the summer, a colleague (Martin Gemborn Nilsson) and I have been working on setting up a real-time BCI system. We had our struggles, but in the end, we managed. We used Timeflux and Psychopy. The BCI system detects the user’s workload (“how hard is the user thinking”). To calibrate, the user does an n-back experiment where theContinue reading “Summer BCI project”

First Abstract

Big news! I have submitted my first abstract for a poster session! Woohoo! It is a one-page abstract where I describe my work with calibration for Brain-Computer Interfaces. The idea is to create a system that automatically decides when to do calibration and when to use the system. It is brilliant! If the abstract isContinue reading “First Abstract”

So much Knowledge

Last week I attended a very inspiring webinar from the BCI society by Dr. Christian Herff. It was about machine learning for BCI systems. When I started my Ph.D. studies in august 2019, I knew nothing about BCI systems and machine learning. Since then, I have taken courses and read a lot about the topics and feel somewhatContinue reading “So much Knowledge”


During the last week, I have talked a lot about ethics in connection to Brain-Computer Interfaces. I can’t deny that it sometimes feels a bit like science fiction when we consider a future where everyone uses BCI systems in their everyday life as seamlessly as we use cellphones today. But it is nevertheless a relevantContinue reading “Ethics”

First data collection

Today was one of those big days: I collected my first set of EEG data! I did a simple trial where the test person (my husband in this case) imagined to lift his right or left hand. I am so proud that I got everything to work: the stimuli program, mounting the EEG cap, andContinue reading “First data collection”
