Tatjana (Tanja) Eisner was born in 1980. She is a mathematician from Germany and Ukraine. She studies different areas of advanced mathematics. These include how numbers work and how systems change over time. Today, she is a professor of mathematics at Leipzig University in Germany.

Her Journey in Math

Tanja Eisner was born on July 1, 1980, in Kharkiv, Ukraine. She also has German citizenship.

Early Studies

She first studied applied mathematics. This was at the National University of Kharkiv in Ukraine. She finished her diploma there in 2002. A diploma is like a first university degree.

Then, she moved to Germany. She earned another diploma in mathematics in 2004. This was at the University of Tübingen.

Becoming a Doctor of Math

After that, she continued her studies. She earned her Ph.D. in 2007 from the same university. A Ph.D. is a very high university degree. It means you are an expert in your field. Her Ph.D. paper was about the "Stability of Operators and C0-Semigroups." Her professor, Rainer Nagel, helped her with this work.

Teaching and Research

From 2007 to 2010, Tanja Eisner worked as a research assistant. This was at the University of Tübingen. She then became a professor.

From 2011 to 2013, she was an assistant professor. She taught at the University of Amsterdam in the Netherlands. In 2013, she became a full professor. She joined Leipzig University in Germany.

Books She Wrote

Tanja Eisner has written several math books. These books are for other mathematicians.

• She wrote a book called Stability of Operators and Operator Semigroups. It was published in 2010.
• She also helped write another book. It is called Operator Theoretic Aspects of Ergodic Theory. She wrote this with Bálint Farkas, Markus Haase, and Rainer Nagel. It came out in 2015.
