• Kevalee Shah (University of Cambridge): Benchmarking contrastive learning algorithms
• Chuen Low (University of Cambridge): Attention models for timeseries
• Yu Yvonne Wu (University of Cambridge): Weakly-supervised and self-supervised learning
• Shohreh Deldari (UNSW Sydney): Multimodal self-supervised learning
• Sofia Yfantidou (Aristotle University): Machine learning fairness
• Francesco Pase (University of Padova): Self-supervised federated learning
• Aashish Kolluri (National University of Singapore): Multimodal adapters for large models
• Ryuhaerang Choi (KAIST): Data-centric multi-task learning

🕳️🐇 Personal

Non-academic things about me: I love music, both playing and listening. I am mostly into art rock and indie folk, with the occasional exception of some well-crafted pop. Although I am an accordionist by training, over the last few years I've been playing mostly piano and ukulele. In a previous life, I performed with the critically acclaimed band The Children of the Oldness (aka Kore Ydro) and recorded the album "Consortium in Amato" (listen here).

I also enjoy street photography and in particular playing with light—photography comes from Greek φως (light) and γραφή (writing), or drawing with light. A sample of my shots is on Flickr and one of my landscapes was featured in the Huffington Post.

Lastly, and perhaps most importantly, I'm always on the lookout for ways to move items from the "non-academic list" to the "academic list"—let me know if you'd like to help!
