Guillem Collell is a Principal AI Researcher based in Helsinki with 10 years of experience applying deep learning at the intersection of computer vision, NLP and AI security. He holds a PhD in Computer Science and has led academic and industrial projects from KU Leuven and MIT to Huawei, delivering state-of-the-art multimodal representation methods and practical systems for abusive content detection. At Huawei he scaled transformer- and LLM-based pipelines—combining ensembling, distillation, quantization and tensor parallelism—to improve production precision/recall while keeping inference costs low. His research has produced top-ranked competition results and tangible production gains, including a reported zero-shot +30% lift for image abuse detection through diffusion-based synthetic data. Trained in mathematics, neuroscience and neuroeconomics, he pairs rigorous theoretical insight with pragmatic engineering and a taste for hard puzzles. He routinely mentors PhD researchers and bridges academia and industry to turn novel multimodal ideas into deployable systems.
