I am a post-doctoral researcher in the School of Informatics at the University of Edinburgh. My current focus is on understanding clusters of long term conditions (multimorbidity) in patients using machine learning. I also worked on an EU Horizon 2020 funded research project Helios exploring ways of learning users' activities, and contexts for making personalized connections, and content sharing over (decentralized) social networks.
I graduated with a PhD in Computer Science from Trinity College Dublin in March 2021. My PhD supervisor was the late
Prof. Séamus (Shay) Lawless, and later I was supervised by Prof. Owen Conlan. My PhD thesis, broadly speaking, is about exploring Information Retrieval based approaches for contextual recommendation, with a particular focus to improve precision at top ranks.
Check out our recent Inf. Retr. J. and SIGIR 2020 work on how to effectively recommend 'points of interests' to users catering to their personalized preferences, and CIKM 2020 work on relevance feedback with query variants.
Generally speaking, my research interests include personalised information retrieval, contextual recommendation, and information retrieval from noisy texts. More specific keywords are Search; Retrieval models; Relevance feedback; Word/context embedding; User preference modeling; Simulated user agents; Unsupervised, weakly supervised, and supervised (learning to rank) approaches applied in different retrieval and recommendation tasks.
