Data Scientist | Machine Learning Engineer

I work as a data scientist with drug screening data for finding novel treatment strategies against certain types of cancer. The data consists of drug-response curves for novel drug combinations, and the main goal is to identify potential drug synergies based on features derived from commonly used drug interactions models. I further build a dashboard app based on Dash and Plotly to visualize experimental data and analysis, running in the background, in an interactive manner.

Based on stakeholder’s interests in typical delivery routes, I have conceptualized and implemented an algorithm for solving time-constrained vehicle routing optimization problems using the Google OR and OptaPlanner software framework. The primary programming languages were Kotlin (OptaPlanner framework) and Python (Google OR). The solver is designed for large scale problems, handling thousands of scheduled visits per day.

As a member of the data science team of the Norwegian Corona tracing app ‘Smittestopp’, I developed the backend for the data analysis pipeline and algorithms, which were tailored to identify contacts between individuals based on geospatial data (GPS) and Bluetooth data. The primary backend language was Python. The data was stored in MS SQL data bases. Due to the large amount of streaming data, database design was of key importance to facilitate fast queries within from the Python backend. We further used real-world test scenarios to measure the reliability and quality of the tracing app. These findings are published as a report on the Simula webpage as well as in an upcoming Springer book.

As part of the systems engineering team, I developed a model for forces emitted by spinning reaction wheels on a deployed satellite. Spinning reaction wheels stabilize the satellite’s position in space, but cause tiny vibrations that lead to blurring of images taken by the satellite’s cameras. My model helped to understand these effects and was used to show that existing heuristics are too pessimistic, as illustrated in this article.
