Angelika Steger facts for kids
Angelika Steger, born in 1962, is a very smart scientist who works with both mathematics and computer science. She is a professor at ETH Zurich, a famous university in Switzerland. Her work helps us understand how to solve complex problems using computers and math, especially in areas like graph theory and algorithms.

Her Journey to Science
Angelika Steger studied at several universities. She started her studies at the University of Freiburg and Heidelberg University in Germany. Later, she earned a master's degree from Stony Brook University in the United States in 1985.
She then went back to Germany and completed her doctorate degree at the University of Bonn in 1990. Her special project was about "random combinatorial structures," which means studying how things can be arranged in different ways, even by chance. She continued her advanced studies at Bonn until 1994.
After teaching for a short time at the University of Kiel, she became a professor at the University of Duisburg in 1995. A year later, in 1996, she moved to the Technical University of Munich. Finally, in 2003, she joined ETH Zurich, where she is still a professor today.
What She Studies
Professor Steger's main interests are in:
- Graph theory: This is a part of mathematics that studies "graphs." These aren't like bar graphs, but networks of points (called "vertices") connected by lines (called "edges"). Think of a map with cities as points and roads as lines.
- Randomized algorithms: These are special computer instructions that use randomness to help solve problems. Imagine flipping a coin to make a decision in a game – these algorithms do something similar to find solutions quickly.
- Approximation algorithms: Sometimes, finding the perfect answer to a problem takes too long. Approximation algorithms find a very good answer that is close to perfect, but much faster.
Books She Wrote
Angelika Steger has written books to help others learn about her field.
- She wrote a textbook in German about combinatorics. This is the study of counting, arranging, and combining things.
- She also wrote a book about the Steiner tree problem. This problem is about finding the shortest way to connect a set of points using extra points if needed.
Awards and Recognition
Professor Steger has received important honors for her work:
- In 2007, she was chosen to be a member of the Academy of Sciences Leopoldina. This is a very old and respected science academy in Germany.
- She was also an invited speaker at the International Congress of Mathematicians in 2014. This is a huge meeting where top mathematicians from all over the world share their latest discoveries. Being invited to speak there is a great honor.
