+<li> <H4>[CU9] Proving Programs to be Correct</H4>
+
+ <p>
+ I am one of the main developers of the interactive theorem prover
+ <A HREF="http://isabelle.in.tum.de">Isabelle</A>. This theorem prover
+ has been used to establish the correctness of some quite large
+ programs (for example an <A HREF="http://ertos.nicta.com.au/research/l4.verified/">operating system</A>).
+ On a much smaller scale, there are a few programs and underlying algorithms where it
+ is not really understood whether they always compute a correct result. The aim of this
+ project is to completely specify an algorithm in Isabelle and then prove it correct (that is,
+ it always computes the correct result).

  I am also open to project suggestions from you. You might find some inspiration from my earlier projects:
