Personal profile

Research Interests

My research interests lie in the field of host-pathogen interactions and how Klebsiella pneumoniae interacts and modulates host immunity.

I am currently investigating how Klebsiella pneumoniae takes control over host post-transcriptional modifications (SUMOylation and other ubiquin-like modifications) to alter cellular responses.
