Assistant Professor, University of Helsinki, Finland
Department of Computer Science | Finnish Center for Artificial Intelligence (FCAI)

Luigi Acerbi leads the Machine and Human Intelligence group at the University of Helsinki. Before that, he was a postdoctoral researcher in computational neuroscience and machine learning at New York University (NY, USA) with Wei Ji Ma and at the University of Geneva (Switzerland) with Alexandre Pouget. He obtained his PhD from the University of Edinburgh (UK) as part of the Doctoral Training Center in Neuroinformatics and Computational Neuroscience, working with Sethu Vijayakumar and Daniel Wolpert. He spent several months of his PhD at the Computational and Biological Learning Lab in Cambridge (UK). Before that, he studied theoretical physics and computer science at the University of Milan-Bicocca (Italy). He is an affiliate member of the International Brain Laboratory, a member of ELLIS (European Laboratory for Learning and Intelligent Systems), and an off-site visiting scholar at New York University. He enjoys boardgames and speculative fiction.

Doctoral Student
Researcher in Sample-Efficient Probabilistic Machine Learning

Chengkun will join the lab this summer as a doctoral student. Previously, he completed the Bachelor program at Shanghai Jiao Tong University (SJTU) and a double Master program at SJTU and Ecole Centrale Paris. After working on computer vision and robotics problems, he now focuses on the foundations of machine learning and novel probabilistic learning methods, with a special interest in sample efficiency. In his spare time, Chengkun enjoys reading, playing the guitar and taking photographs.

Research Assistant
marlon.tobaben [at]
Machine Learning Engineer

Marlon is an M.Sc. student in Data Science and joined the lab in 2021 to work on porting the Variational Bayesian Monte Carlo toolbox to Python. Previously, he completed a work-integrated B.Sc. program in Computer Science and Business Management at the NORDAKADEMIE (Germany) while working at one of Europe’s largest E-Commerce companies. He spent several months studying Business at the University of Victoria (BC, Canada). In his free time, Marlon hikes, cycles, explores countries and attends music festivals.

Master's Thesis Student
aki.rehn [at]
Researcher in probabilistic machine learning
Aki is an M.Sc. student in Data Science and joined the lab in 2021 to work on his Master's thesis combining deep learning with Bayesian nonparametrics. After working in the IT industry for a long time, in 2017 Aki joined the University of Helsinki to get his B.Sc. in Computer Science, minoring in Mathematics. He is interested in many areas of computer science, from operating systems to networking and cryptography, and more recently in machine learning and neural networks. When Aki is not working with computers, he can often be found at a local disc golf course, near a billiards table, or just enjoying a beer with friends.

Research Assistant
mikko.aarnos [at]
Machine Learning Engineer

Mikko is an M.Sc. student in Mathematics and joined the lab for the summer of 2021 to work on porting Variational Bayesian Monte Carlo and related toolboxes to Python. Before joining the University of Helsinki, he completed a B.Sc. in Engineering and Natural Sciences at the University of Tampere. During that time, he created one of the stronger open source chess engines in the world, Hakkapeliitta. Mikko spends his free time swimming and playing various board games.
