Short info
My research activity is primarily related to instrumentation for the ALICE experiment at CERN, but I also develop electronics for other similar projects. I am an active teacher, and I am the program chair in physics. I have also given several popular science lectures.
Research
Ongoing research projects:
- ALICE experiment at CERN: I am currently active in two projects:
- Design of new readout electronics for the Forward Calorimeter (FoCal), a new sub-detector to be commissioned in 2029. FoCal consists of three separate sensor systems: two layered electromagnetic calorimeters (pixels and pads) and a hadronic calorimeter. In this project, I coordinate the design of all readout electronics, with a primary focus on the pixel layer readout electronics.
- Design of new electronics for the Inner Tracking System 3 (ITS3): This project is a continuation of ITS2, completed in 2021. ITS is the innermost detector in ALICE, and ITS2 consists of seven layers of Monolithic Active Pixel Sensors (MAPS). In ITS3, the three innermost layers will be replaced with flexible sensors that are 30 cm long. The goal is to get closer to the collision point and reduce the amount of material in the detector, significantly impacting the data quality from ALICE. My role here is somewhat smaller than for FoCal.
- Proton CT: This is a UiB-driven project to create a CT machine using MAPS ICs (ALPIDE) that takes images with protons instead of photons. The advantage is much more precise dose planning for proton cancer treatment, resulting in less damage to healthy tissue and potentially fewer side effects. This project is an excellent example of technology transfer, using sensors developed for basic research at CERN for medical diagnostics. My role in this project is coordinating the development of readout electronics and power systems.
- Project leader for NORLHC-II: This is an NFR infrastructure project for Norwegian CERN activities related to detector development and computing for the ALICE and ATLAS experiments. As project leader, I am responsible for all communication with the Research Council and ensuring financial management is under control.
- Additionally, I am the local contact person for the ECFA Detector Research & Development groups currently being established. We have expressed interest in several groups and seem to be able to contribute specifically to DRD7.6 Monolithic sensor ASICs in collaboration with UiO and USN.
Ongoing projects related to teaching:
- Pilot project to include programming in physics courses in the bachelor's program: In 2023, we applied for and received 1 MNOK for a project aimed at integrating data processing and numerical solutions of physics problems into all physics courses in the bachelor's program. As of 2023, students learned Python in INF100 in the first semester but did not use it until the fourth semester in the physics lab course (PHYS114). This led to students having to relearn programming in PHYS114. By incorporating a small programming component into all physics courses, we hope students will better see the relevance of INF100 and generally become more proficient in programming through continuous use. This will better prepare them for potential master's projects and the workforce.
- Physics room: In 2025, we are transforming calculation workshops into a physics room for all 100-level physics courses.
- Working group to examine the use/benefit of Large Language Models (LLMs) in teaching: In 2023, a working group was established on the initiative of BIOCEED to explore how to use and not use chatGPT and other LLMs in teaching. We have had two meetings, and an article based on the work done will most likely be published.

Previous research projects:
- ALICE experiment at CERN:
- 2004 - 2008: Design of readout electronics for the ALICE Time Projection Chamber (TPC) and PHOton Spectrometer (PHOS). This was part of my PhD degree.
- 2011 - 2012: Participated in the development of a prototype for the ALICE Forward Calorimeter, primarily focusing on FPGA development.
- 2012 - 2016: Coordinated the development of the upgrade for the ALICE TPC readout electronics. 216 Readout Control Unit 2 circuit boards, with entirely new electronics, were installed in 2016, resulting in more stable operation and higher data throughput for the TPC detector. One PhD student from UiO was involved in the project. Additionally, I participated in the specification phase of the ALICE TPC upgrade installed in 2021, conducting simulations of data rates and memory usage, as well as some simple FPGA designs to make informed decisions about various solutions.
- 2016 - 2022: Development of readout electronics for the ALICE ITS2 detector. We conducted hardware reviews of readout boards, FPGA design, software design, and testing. Three PhD students from UiB were involved in the project.
