Mathias Parisot

Research Engineer

Mathias did his Master's thesis internship at Zeta Alpha and decided to stay on as a research engineer. No problem is too difficult for him, and he simply enjoys training very large models.

In his spare time he compensates for that by running very large distances.

Eduardo Ochoa

Senior Data Engineer

Eduardo is a former physics researcher turned Data Scientist and Data Engineer. He loves complex systems, but maybe even more to make complex things simple. Somehow more attached to Haarlem than to Amsterdam, he has also been bitten recently by the Zeta Alpha running craze, and has successfully completed the Dam tot Dam loop. Sometime he looks sentimental when Mexican food is discussed.
