I am a Ph.D. student at TUM's Computer Vision Group, headed by Research Interests. My current research focuses on improving monocular 3D reconstruction and localization accuracy and efficiency.

Before joining the Ph.D. program, I worked as a Machine Learning Engineer at Knowlix GmbH. There, I researched OCR modeling and LLMs such as GPTs and Llama. I also designed data and machine learning pipelines and applied machine learning techniques to solve real-world problems.

I completed my Master's studies in Electrical Engineering and Information Technology at TUM. My focus was on Automation, Robotics, and AI. I spent a semester abroad at NTU Singapore, where I studied Deep Learning for Natural Language Processing and Genetic Algorithms.

For my Master's thesis, I worked at BMW Group AG on AR glasses and head 6DoF pose estimation based on 3D multi-view geometry reconstruction and deep learning. My research involved implementing a system that could estimate the head and AR glasses pose with high accuracy (Project). It resulted in a publication titled "Comparing Head and AR Glasses Pose Estimation."

I also completed my Bachelor of Science in Electrical Engineering and Information Technology at TUM, with a focus on Signal Processing. During my Bachelor's thesis, I worked on generative modeling using Capsule Generative Adversarial Networks at the Chair of Robotics, Artificial Intelligence, and Real-time Systems at TUM.
