What I'm looking for

I’m looking for research positions or industry roles in AI and computer vision that offer opportunities for growth, problem-solving, and technical innovation in real-world applications.

At Guilan University, I co-developed a geometry-biased transformer model for detecting dental caries in panoramic X-ray images. I implemented and trained deep learning models in Python and PyTorch, and contributed to the methodology and experimental analysis for a paper published in Neural Computing and Applications.

My work includes preprocessing and augmenting data, evaluating models with standard metrics, and collaborating on research writing and presentations. I’ve also supported teaching in computer vision, research methods, and internet engineering.
