About
I’m a senior machine learning researcher at RISE Research Institutes of Sweden within the deep learning research group, where my main research interest is to develop ML methods for a broad range of environmental applications (e.g. climate adaptation and humanitarian aid causes).
Before joining RISE, I conducted my doctoral studies in computer vision at the Faculty of Engineering, Lund University, under the supervision of Prof. Cristian Sminchisescu. In my research, I applied deep reinforcement learning to computer vision tasks such as object detection and active vision, with the aim of making visual recognition systems more flexible and adaptive. I successfully defended my PhD thesis Reinforcement Learning for Active Visual Perception in June, 2021.
Prior to my doctoral studies, I received a bachelor and master degree within engineering mathematics (in Swedish: Civilingenjör i teknisk matematik) from the Faculty of Engineering, Lund University. During this time, I spent a summer (2014) as a research intern at California Institute of Technology, where I improved an algorithm for clustering, a fundamental problem in machine learning and statistics. I also strengthened some theoretical recovery guarantees. This work resulted in a journal publication in JMLR. My supervisors were Assoc. Prof. Brendan Ames and Prof. Joel Tropp.
I’m an advocate for facing our difficult future (and present, for many), collectively and individually, so that we can try to reduce harm and suffering. I may write more about this under my personal page at some point, but for anyone interested in learning more about what is difficult about our future, I warmly recommend the podcasts The Great Simplification, Breaking Down: Collapse (and the follow-up podcast Building Up: Resilience), Planet: Critical, and Entangled World. Two other short and self-contained podcasts that I also recommend are Power: Limits and Prospects for Human Survival and Tipping Point: The True Story of “The Limits to Growth”. I also try to summarize some reasons why in this video.
