Halil Arda Özongun

Senior Computer Science Student

AI Researcher & Software Engineer

I am a senior Computer Science student at Bilkent University interested in multimodal large language models and interpretability.

My work sits between research and engineering: I like building practical systems while exploring how models perceive, reason, and represent the world.

Experience

EML Group — TUM & Helmholtz February 2026 – Present
Research Intern · Advisor: Prof. Zeynep Akata
Training Sparse Autoencoders on vision-language models to extract interpretable features, and examining whether societal harm benchmarks capture real-world harm or rely on narrow proxies like refusal rates and stereotypical MCQ selection.
HUCVL July 2024 – Present
Deep Learning Research Intern · Advisor: Prof. Aykut Erdem , Prof. Erkut Erdem
Researching low-light image enhancement with diffusion-based generative models, building a synthetic data pipeline for varying illumination and noise conditions and exploring physics-guided priors for perceptual quality.
KUIS AI Center May 2025 – May 2026
Deep Learning Research Intern · Advisor: Prof. Aykut Erdem , Prof. Erkut Erdem
Developing a diffusion-based framework for 360° panoramic video generation, focusing on realistic motion and spatial continuity, and leading evaluation against prior methods.
Ekinsoft June 2025 – July 2025
Computer Vision Intern
Optimized CNN and ViT-based object detection on large-scale license plate data and Dockerized end-to-end training and inference pipelines for GPU and edge deployment.
DLR Lab — Bilkent University September 2024 – March 2025
Undergraduate Researcher · Advisor: Asst. Prof. Ayşegül Dündar
Worked on text-to-video generation with diffusion models, developing a SAM2-based segmentation pipeline with morphological operations to improve temporal coherence.
Bilkent University October 2023 – May 2024
Lab Tutor
Led lab sections for CS115 (Python) and CS101 (Java), covering algorithms, data structures, and object-oriented programming.
