ADAPT Collaborator

Profile picutre

I am an assistant professor in Computing in the School of Computing at Dublin City University (DCU). Between 2017 and 2019 I worked as a post-doctoral researcher in the ADAPT centre, DCU. I hold a PhD in computer science engineering from KULeuven Belgium. During my PhD studies I have worked on the design and development of artificial intelligence software for learning and reasoning with uncertain data. Previously to joining the ADAPT centre at DCU I was leading KantanLabs - a research and development group committed to advancing language technology within which I worked on introducing innovative technology such as efficient word reordering, improved alignment, neural MT and so on.
My academic interests are in the field of machine translation, cross-lingual information retrieval, natural language processing and subtopics related to optimisation, quality, performance, fairness, low-resources.
I have been involved in the teaching of courses on Linux, machine translation, machine learning and programming languages.
I have a strong industry experience having worked on projects with, among others, Microsoft, eBay and Huawei.
