I am a research associate at the University of Cambridge working with Prof. Cecilia Mascolo. My work enables efficient ML and AI to make the most out of real-world data (e.g. timeseries, audio, images, radio, mobile sensors, or other modalities) on mobile and IoT/edge devices. I am particularly interested in the following paradigms:
- Mobile computing/sensing. Mobility, interactivity, context awareness or security -- What are their limits?
- On device learning. Resource constraints, robustness or low latency -- How to run models efficiently?
- Model adaptation and generalization. Test time adaptation, domain adaptation or personalization -- How to update the model?
Previously, I completed a PhD in Computer Science at the The University of New South Wales working with Prof. Wen Hu. I was an Australian Government Research Training Program (RTP) scholarship holder between 2017-2021.
