Luke Gregor

Senior Data Scientist

Research

(Alumni)

Luke completed his PhD in oceanography at the University of Cape Town in 2017.

After a short stint at the Council for Scientific and Industrial Research in Cape Town, he joined the Environmental Physics group at ETH Zürich as a postdoc in 2019. Here, his research focussed on ocean biogeochemistry. Specifically, he used machine learning approaches to estimate surface ocean pH and surface ocean carbon fluxes from satellite and ship-based observations.

Luke has also been involved developing scientific data processing tools for several autonomous observation platforms.
