Hello, I am Supriya Khadka

NLP & HCI Researcher

Hello, I am Supriya!


I am an NLP & HCI Researcher with interests in Human-AI interaction and User-centred Privacy. My goal is to build intelligent systems that are not only efficient but also trustworthy and secure, particularly in sensitive social and medical settings.

I recently completed my Master of Science by Research (MRes) at the Research Centre for Computational Science & Mathematical Modelling, Coventry University, UK. My thesis, "Automated Clinical Coding with a Hybrid Evidence-Based Pipeline: Investigating Dataset Quality, Undercoding and Coding Errors," supervised by Dr. Xiaorui Jiang and Prof. Vasile Palade, focused on optimising the clinical coding process using large and pre-trained language models. This research and my degree at Coventry were supported by the prestigious British Council Women in STEM Scholarship.

My technical foundation was built at the Institute of Engineering, Pulchowk Campus (Tribhuvan University) in Nepal, where I completed my Bachelor's in Computer Engineering. It was there, amidst a vibrant community of brilliant minds, that I first experimented with machine learning and discovered the potential of technology to solve real-world problems.


When I'm Away from the Keyboard

I love going on hikes, even though my body gives up almost instantly when climbing uphill! I also love buying novels, reading novels, and talking about novels in my free time. If you ask me for recommendations, these are probably the ones I will suggest. The list includes every genre; take your pick!

I also enjoy watching live theatre, movies, and series. If you want to talk about NLP, books, or movies, hit me up!
