After 2+ years, finally in person meeting with the community hEART conference in Leuven. Six contributions from our side (Arkadiusz Drabicki, Michal Bujak, Marko Maričić, Peyman Ashkrof, Arjan de Ruijter and Farnoud Ghasemi presented results of our joint work). Plus a great keynote by prof. Oded Cats, summarizing roughly all on which our lab is founded, including ExMAS and MaaSSim.
