Tosin Adewumi is a postdoc researcher in natural language processing (NLP). I successfully defended my Ph.D. in June 2022. I was under the supervision of Prof. Marcus Liwicki as principal supervisor and Foteini Liwicki as assistant supervisor. My Ph.D. thesis is titled "Vector Representations of Idioms in Data-Driven Chatbots"  and it involves the creation of an idioms dataset in English (with over 1,100 cases spread across 10 classes) and training, using state-of-the-art, open-domain models, in order to have idiom-aware conversational systems. We also created the Swedish analogy test set for word embeddings and the AfriWOZ dataset for 6 African languages.

My previous position was the Director of Operations at Ephphatha Consulting, in Nigeria. My experience as a professional in the IT industry has spanned both public and private organisations. I am also a member of Nigeria Computer Society (NCS). In 2016, I had the privilege of being the seminar speaker on e-petitions for members of the public petitions committee of the Federal House of Representatives of Nigeria.
