Welcome to my personal homepage
I am a senior scientist at Spotify based in UK, working in machine learning and information retrieval. Currently, I'm leading efforts around graph-based recommendations, while also exploring the potential of large language models for search and recommendations.
Before joining Spotify I was at Amazon, working on products in core ML, supply chain optimization and Alexa shopping. Prior to that I had co-founded Inferentia, a start-up that was eventually acqui-hired by Amazon. I also worked as a research associate in machine learning and social robotics at Sheffield, and before that I pursued my PhD degree working with prof. Neil Lawrence. Deep Gaussian processes, which was a core topic introduced as part of my thesis, earned the Test of Time Award at AISTATS as "a paper from 10 years ago that has had a prominent impact in the field".
More broadly, my research interests are: transfer learning, deep representation learning (in particular graph neural networks and language models) and uncertainty quantification. Lately I'm focusing a lot on information retrieval applications, such as recommender system tasks. In the past I worked a lot with Bayesian probabilistic models and their extensions to the deep learning paradigm, as well as applications to decision making.
