Sarah Ibrahimi

Researcher

Computer Vision & Multimodal Learning

I obtained my PhD degree in Computer Vision and Multimodal Learning at the University of Amsterdam in 2024, under the supervision of Prof. Dr. Marcel Worring and Dr. Nanne van Noord. My background is in Computer Science & Engineering (MSc), Mathematics (BSc), and Theater and Dance Studies (BA).

My main areas of interests are Multimodal Learning, Visual Retrieval tasks, AI & Creativity and more recently Hyperbolic Learning.

I am now on the job market and open to research positions starting from Summer or Fall 2025.
