Research Interests

My primary research interests are digital health, evolutionary models, and cancer informatics for improving interventions. My work spans various dimensions of cancer research, including tumor imaging, survival prediction, and eco-evolutionary models.

Sensor Data as a Measure of Cancer Evolution

Whilst mutational processes underly evolution and selection in cancer these can be difficult to measure and observe. During disease progression, patients experience phenotypic and symptomatic changes. Using digital health measures of activity, sleep, neurological, and physical function may allow us to understand disease progression and patient experience from a new perspective. Charting symptom and functional evolution with cheap wearable devices could complement expensive intermittent imaging. Ideally, we can leverage continuous monitoring to improve care, intervention timing, and cancer control.

Feature Engineering for Digital Twins

Sensor-derived datasets comprise high-frequency time series. Feature engineering allows us to derive different summary statistics from raw or processed data. Topological data analysis (TDA) provides suites of new tools that can be leveraged to extract features and is highly effective across multiple types of clinical data including within cancer informatics. Using TDA-derived features as inputs for data-driven patient models may allow us to identify new emergent patterns in clinical images, evolutionary trajectories, and patient motion data

Modeling and Game theory

Human diseases are typically bolstered by ecology and interactions. This adds combinatorial complexity to a system's dynamics. I am interested in how these effects play a role in some of our cancer models and how the composition of a patient's cancer can affect symptoms, treatment efficacy and disease severity.

Topology is cool
