I am a passionate AI researcher and engineer with a strong focus on Vision-Language Models (VLMs), Retrieval-Augmented Generation (RAG), and LLM engineering. My broader interests include self-supervised learning, foundation models, generative AI (such as VAEs, GANs, and diffusion models), and multimodal systems involving 3D perception, sensor fusion, and few-shot or cross-modal learning.
I previously worked as a Research Assistant at Fraunhofer IOSB in Karlsruhe, Germany, from May 2023 to January 2025, where I developed an LLM-powered chatbot using RAG, LangChain, and RAPTOR. My work also included training VoxelNeXt on the Pandaset dataset for real-time 3D object detection in autonomous driving scenarios and presenting an Advanced Occupant Monitoring System integrated into a Level 3 Mercedes-Benz vehicle. I regularly worked with tools such as Python, PyTorch, FAISS, Docker, GitLab, AWS, and CI/CD pipelines.
I hold a Master’s degree in Mechatronics from the University of Siegen, Germany, with research focused on Deep Learning, Computer Vision, and NLP. Prior to this, I earned a Bachelor’s degree in Mechanical Engineering from the National Institute of Technology (NIT) Hamirpur, India.
