Zum Ersti-Programm "Auf Darwins Spuren" - Alles über die Darwineumsexkursion, die Dozentenvorträge und die Absolventenvorträge!

 

Consultation Hours

Im Sommersemester 2016: Montags, 14 - 15 Uhr sowie nach Vereinbarung.

Anmerkung: Meine Sprechstunde ist grundsätzlich flexibel und richtet sich danach, wann jemand mit mir sprechen möchte - wenn Sie mit mir sprechen möchten (über eine Vorlesung, über Studienprobleme, über eine Entscheidung bezüglich des Studiengangs, über Informationen bezüglich Biomathematik, etc.), dann nehme ich mir auch außerhalb der Sprechstunde Zeit dafür! Sie können einfach einen Termin mit mir vereinbaren, am besten per E-Mail.

Teaching

 

Research interests

  • Biomathematics, in particular phylogenetics and population genetics
  • Discrete Mathematics
  • Combinatorics
  • Probability Theory
  • Graph Theory
  • Group Theory

Wenn Sie Interesse haben, in einem dieser Gebiete eine Abschlussarbeit zu schreiben (Bachelor, Master, Promotion), so zögern Sie nicht, sich an mich zu wenden.

If you are interested to write a thesis (Bachelor, Master or PhD) in any of the topics mentioned above (or a combination thereof), please do not hesitate to contact me!

Possible research topics for students in my working group can vary according to the applicant's own interests between purely theoretical and applied - the latter either in the sense of programming or in the sense of data analysis (or both). Collaborations with biologists or computer scientists are possible.
