Sevvandi is a mathematician working on data science/analytics related topics such as anomaly detection, meta-learning and streaming data. She likes working on real world problems, especially ones that are motivated by industry.
She came to statistical learning from a pure mathematics background. Her PhD was in mean curvature flow, which lies in the intersection of partial differential equations and differential geometry. She likes to bring her geometric intuition to solve data science/analytics problems.
Sevvandi is interested in data science/analytics research projects broadly in the following areas:
- Anomaly/outlier detection
- Streaming data
- Event detection
- Spatio-temporal data
- Dimension reduction
- Bushfire mitigation
She is also interested in industry projects. From 2016 to 2019, she worked with an industry partner on intrusion detection.
