Fieke Dekkers

Fieke Dekkers (full name Sophia Antonia Janna Dekkers) is a Dutch mathematician. As a schoolgirl she competed for the Netherlands at the International Olympiad in Informatics in 1990, 1991, 1992 and 1993, winning a bronze medal at IOI 1991 in Athens. She studied mathematics and physics, earned a PhD in theoretical mathematics in England, and after two postdocs shifted toward applied mathematics. Since 2006 she has worked at the Dutch National Institute for Public Health and the Environment (RIVM), and she also lectures at Utrecht University's Mathematical Institute (Mathematical Modeling group). She remains tied to the Olympiad world, serving as a leader/deputy for the UK IOI team (2019-2023) and supporting the Netherlands' European Girls' Olympiad in Informatics (EGOI) effort.

Notes2

• Competed for the Netherlands at four consecutive IOIs (1990 finalist, 1991 bronze medal, 1992, 1993) - one of the earliest Dutch IOI contestants, marking her as part of the first cohort of Dutch Olympiad programmers.May 25, 1991
• Profiled in the Dutch mathematics magazine Pythagoras (April 2021): worked at RIVM since 2006, drawn from abstract theoretical math toward applied modelling after feeling the field was too narrow.Apr 1, 2021
• Full legal name is Sophia Antonia Janna Dekkers; 'Fieke' is the common name - matching the IOI profile to the RIVM/Utrecht University mathematician.
