The scientific focus of my academic career can be divided into three main areas of interest.

 

(A) Genotypic and phenotypic characterisation of novel animal HBV/HDV-viruses.

Here, I characterized novel animal HBV/HDV by cloning and expression and subsequent infection in vitro using own established infection systems for HBV/HDV and pseudotyped HDV (see below).

(B) Establishment and improvement of HBV/HDV-infection systems in vitro

Since 2003, I have been developing and optimising systems for both in vitro generation of human/animal HBV/HDV and corresponding infection systems using primary hepatocytes and susceptible permanent cell cultures.

(C) Improved molecular diagnostics and characterization of HBV and HDV infection

The phenotypic characterization of a large number of clinical HBV/HDV isolates and the genotypic analysis of ancient HBV isolates were successfully completed as part of the activities of the National Reference Centre for HBV/HDV in Giessen, which I have been heading since 2011.
