I am a 7th year MD/PhD Student at the University of Toronto, currently wrapping up my PhD (Year 5) in the Department of Computer Science and the Vector Institute. I am also in the midst of my clinical clerkship rotations primarily at Unity Health Network (St. Michael’s Hospital).

I am supervised by Dr. Anna Goldenberg.

My research interests lie at the intersection of machine learning and health - in particular, how can we leverage the vast data from wearable devices to make meaningful inferences about human health?

Aug 21, 2024 Our work at the SickKids Critical Care Unit was recently accepted in-proceedings at Machine Learning for Healthcare 2024: we uncover meaningful signal buried within noise artifacts in high-frequency physiological waveform data. Rather than removing this noise, we built and deployed ML models to identify it in order to achieve a variety of important clinical tasks - stay tuned for full-paper!
Feb 16, 2024 Check out our new preprint introducing and proposing methods to handle temporal label noise from time series data: Learning from Time Series under Temporal Label Noise.
Dec 20, 2023 Check out our latest article in nPJ Digital Medicine, where we use causal discovery and multimodal time-series data from wearables to understand the heterogeneity of stress!
Dec 8, 2023 Our workshop proposal for Learning from Time Series 4 Health was accepted at ICLR 2024, see you in Vienna! More details to follow.
Dec 22, 2022 Honoured to have been awarded a prestigious CIHR Vanier CGS Scholarship - $150,000 in funding over 3 years.
