I’m passionate about finding hidden patterns and trends in data.


I began life in Enköping, Sweden in 1986. As a young boy, I quickly found an interest in Mathematics and Computer Science, which led me to study Engineering and then to pursue a PhD based on research and coursework. I received my PhD in Automatic Control in May 2016 after successfully defending my thesis which contained a total of 17 peer-reviewed papers (13 conference papers and 3 journal papers) published at top conferences and journals in the fields of Computational Statistics and System Identification. Currently, I am developing automated data-driven algorithms for building dynamical models as a PostDoc at the School of Engineering at the University of Newcastle, Australia.

During my research career, I have worked at a number of different companies and universities. I visited Prof. Robert Kohn at he University of New South Wales,  Australia during the autumn of 2014 as part of his PhD studies. I have also worked as a Research Scientist at Sectra AB and as a PostDoc at the division of Statistics and Machine Learning at Linköping University.

The Economist has described data as the new oil which can result in the next industrial revolution. Everyday, more and more information is gathered from sensors and the Internet. As a result, Big Data, Statistics and Machine Learning (in short Data Analytics) have become essential tools to generate insights from this data.

The objective in these fields is often to condense the data into a model, which can be used to gain understanding, to make decisions or to forecast future behaviours. However, many models and the algorithms that fit them to data cannot yet cope with the complex, dirty and large data materials. More work is required to better scale with the amount of information and to accelerate current methods for model building.

I am passionate about finding hidden patterns and trends in data such as numbers, images and documents to learn more about medicine, economics and society at large. During my PhD studies, I spent five years learning and developing more efficient algorithms for Data Analytics.

I now aim to make use of my expertise to improve the world in terms of health care, medicine and the environment. I believe that learning from data is essential in this quest by enabling improved data-driven decision making and forecasting.
