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
If you are a self-funded Ph.D. student and would like to work with me, I am interested to work on evaluating and improving (1) fairness & robustness, (2) accessibility, (3) reasoning skills, and (4) efficiency of language models. Apart from these, I am interested in coreference resolution and interesting psycholinguistic analyses of text ot multimodal inputs.
