Dr, Senior Research Engineer

Imperial College London



I am a computer scientist from Turkey, working on problems related to natural language processing. I received my PhD in 2019 from the Informatics Laboratory (LIUM) of Le Mans University. During summer 2018, I visited Johns Hopkins University as a graduate student in the Grounded Sequence to Sequence Transduction Team, as part of the JSALT workshop.

I am currently a senior research engineer at contex.ai, a start-up company trying to solve the immense problem of online toxic content moderation, by leveraging contextual and multimodal machine learning techniques. Previously, I worked as a postdoctoral research associate with Prof. Lucia Specia, at Imperial College London.

Between 2012-2017, I worked as a research & teaching assistant in the Computer Engineering Dept. of Galatasaray University in Istanbul, Turkey where I lectured practical sessions for undergraduate courses such as Algorithms, C Programming, Microprocessors and Operating Systems. I obtained my MSc. degree from Galatasaray University as well where I developed a simple embedded system for a Brain-computer Interface application. You can access my MSc. thesis from here.

Between 2007-2012, I took part in the Pardus Linux project within the Scientific & Technological Research Council of Turkey (TUBITAK) as a full-time Linux developer.

I am a signatory of the petition called Academics for Peace against which a series of unlawful actions have been taken by the Turkish state since 2016. Click here for the recent updates.
