Dr Dimitra Gkatzia

Associate Professor

Biography

Dimitra Gkatzia is an associate professor at the School of Computing at Edinburgh Napier University. She holds a BSc (Hons) from the University of Piraeus (Greece), an MSc on Artificial Intelligence (Distinction) from Heriot-Watt and a PhD in Computer Science from Heriot-Watt University (Edinburgh, UK). After her PhD, she was appointed postdoctoral researcher at Heriot-Watt's Interaction Lab investigating Natural Language Generation methods for information presentation of uncertain data, where she developed the Extended Weather Game for task-based evaluations for NLG (Gkatzia et al., 2015; Gkatzia et al., 2017). In 2016, Dimitra joined Edinburgh Napier University where she currently supervises 3 research students in the area of NLP, and has assumed the role of Programme Leader for BEng (Hons) Computing (2016-2020) and Module Leader for Data Wrangling.

RESEARCH INTERESTS

Dimitra is interested in making computers and robots interact in a human-like way using natural language, while at the same time respecting the privacy of the users as well as protecting the environment (through Green AI). Specifically, she is interested in developing data-driven Natural Language Understanding and Generation techniques that utilise privacy-preserving methods by respecting users' sensitive information and instead employing transfer learning approaches. In addition, she is interested in making dialogue systems (such as Alexa, Siri) converse naturally, by enhancing their responses with commonsense and world knowledge. She envisions a future where humans and robots co-exist and collaborate in domestic, public and work settings.
