Personal profile
Research
My research focuses on detecting anomalies and out-of-distribution patterns in a variety of applications. From detecting deforestation and investigating growth patterns in agriculture to breast cancer detection and point-of-care diagnosis, my work focuses on how mathematics and machine learning can be used as an interdisciplinary tool in other research areas in a responsible and transparent way.
