Computer vision researcher at Aalto University.

During my PhD, I was supervised by Prof. Juho Kannala and Prof. Esa Rahtu. My research interests lie at the intersection of 3D Computer Vision, Scene Understanding, and Deep Learning.

Previously, I was a research intern at Niantic Labs (London) under the supervision of Prof. Gabriel Brostow and Dr. Daniyar Turmukhambetov. Before this, I spent 6 months in Cambridge, UK working on visual perception algorithms for autonomous cars and having fun at Wayve. I also did a research visit to ETH Zurich's CVG Group led by Prof. Marc Pollefeys.

News

Aug. 2020: Our new approach could secure 2nd place in two ECCV 2020 competitions on image-based localization (1 and 2). The slides are available online and this is a project I did during my internship at Niantic Labs.
Mar. 2020: I could successfully defend my PhD thesis on image matching and camera relocalization 🎉🎉🎓! I am very thankful to the thesis pre-examiners (Dr. Vassileios Balntas from FAIR and Prof. Atsuto Maki from KTH) for their comments and very useful feedback and to my opponent (Prof. Victor Lempitsky from Samsung AI Center) for the great discussion during defense.
Jun. 2019: I am very excited to announce that I started a 4-month research internship at Niantic Labs, London.
