I'm Härmel Nestra, a senior lecturer of Institute of Computer Science, University of Tartu.

During my career, I even have published some papers and written some theses (like MSc and PhD ones).

Here, I list the courses I have taught. The pages of the courses are almost all in Estonian.

- 2013 spring, Functional Programming Techniques.
- 2012 spring, Semantics of Programming Languages.
- 2012 spring, Functional Programming Techniques.
- 2011 fall, Seminar on Programming Language Semantics (in English).
- 2011 spring, Semantics of Programming Languages.
- 2011 spring, Functional Programming Techniques.
- 2010 spring, Functional Programming Techniques.
- 2009 fall, Algorithms and Data Structures.
- 2009 spring, Semantics of Programming Languages.
- 2008 fall, Algorithms and Data Structures.
- 2007 fall, Algorithms and Data Structures.
- 2002 spring, seminar Software Systems: Testing.
- 2002 spring, Semantics of Programming Languages.
- 2001 fall, Functional Programming Techniques.
- 1999 fall, Elements of Discrete Mathematics (consisted purely of graph theory at that time).

Among these, semantics of programming languages and functional programming are the closest to my interests. I have also been interested in formal logic and term rewriting, even categories can be attractive for me. Currently I am doing some research work on program slicing theory. During spare time, I sometimes deal with number theory. This interest has grown out from my work in the jury of Estonian mathematical olympiads.

In spring 2003, I worked in Trier University (Germany) for half a year. During this time, I made a lot of pictures of Trier and its county. I have a special webpage for these pictures. The comments are in Estonian but the pictures are not, so just follow the links...

At the moment, the only more thing here which you can read in English is a text about millenniums (no longer very topical).

I hope that's enough at the moment `:)`
