A primary focus of Yarmohammadi’s researc h is using deep learning techniques to transfer existing resources into ot her languages and to learn representations of language from multilingual d ata. She also works in automatic speech recognition and speech translation . Yarmohammadi received her PhD in computer science and engineering from O regon Health & Science University (2016). She joined CLSP as a post-doctor al fellow in 2017.
