Riza Velioglu earned his B.Sc. in Electrical and Electronics Engineering from Istanbul Bilgi University in 2018, followed by an M.Sc. in Intelligent Systems from Bielefeld University in 2021. In 2019, he co-founded a tech startup that raised 6M+ euros in investment, leading the R&D team.
Currently a Ph.D. candidate, his research focuses on Object Detection and Segmentation, Multi-Modal Learning (Vision-Language Models), and Image Generation.
