I am a Lecturer (~Assistant Professor) in Natural Language Processing at the Computer Science Department of the University of Sheffield. Before joining the University of Sheffield, I was a postdoctoral researcher working with Prof. Iryna Gurevych at the UKP Lab at the Technical University of Darmstadt. I got my PhD degree from Heidelberg University where I was supervised by Prof. Michael Strube. I have studied at Alzahra University and the Sharif University of Technology in Tehran for my BSc and MSc in computer science.
Reseach Interests
My research focuses on evaluating and improving language and foundation models, particularly their fairness and robustness, reasoning capabilities (e.g., math or cultural reasoning), accessibility, and efficiency. A central theme is developing rigorous evaluation methods and benchmarks to understand model capabilities and limitations and build more trustworthy and responsible models. My research also explores AI for Science, as well as multimodal models and linguistically and psycholinguistically informed analyses of model behaviour.
If you are a self-funded PhD student interested in working on these or related topics, please feel free to get in touch.
