Otniel-Bogdan Mercea

I am a final-year PhD candidate at the Max Planck Institute for Intelligent Systems and the University of Tubingen, supervised by Prof. Zeynep Akata and Prof. Andreas Geiger within the IMPRS-IS doctoral program. I was also a guest PhD student at Helmholtz Munich and Technical University of Munich, supervised by Prof. Zeynep Akata.

I earned my MSc in Artificial Intelligence from the University of Edinburgh in 2020, with a MSc thesis supervised by Prof. Amos Storkey, and my BEng in Computers and Information technology from Politehnica University of Timisoara in 2019, with a BEng thesis supervised by Prof. Calin-Adrian Popa.

I applied my research expertise in industry through impactful roles, including internships at Google DeepMind (Autumn 2024), supervised by Stefano Pellegrini, Jasper Uijlings, and Cordelia Schmid, on improving SAM 2 for significant occlusion and movement scenarios; and Google Research (2023–2024), collaborating with Anurag Arnab, Alexey Gritsenko, and Cordelia Schmid on efficient adaptation of large-scale models. I also collaborated with Aleksandra Nowak, Utku Evci, and Yann Dauphin from Google DeepMind on related projects. Previously, I was a Machine Learning Researcher at Everseen, developing real-time multi-camera tracking systems.

My research focuses on improving the efficiency of deep learning through data-efficient (low-shot) and model-efficient adaptation methods for large-scale models. I also have extensive experience in multimodal learning (audio-visual, multimodal language models) and video semantic segmentation and tracking.
