About
I am a full professor at the department of computer science of the University of Freiburg, and head of the Chair of Algorithms and Data Structures. On the navigation panel on the left, you will find my list of publications and a short CV. For correct results in "Publish or Perish", search for "H Bast" and exclude "TH Bast", "HJ Bast", "PH Bast", "HD Bast".
My general research interest is aptly described by the words "applied algorithmics", which are explained on the entry page of our chair. Specific topics I am currently interested in and actively researching are route planning algorithms, all aspects of information retrieval (index building, query processing, user interfaces, whole information systems), and natural language processing, with and without deep learning.
