Ph.D. in Biochemical Engineering
Jacobs University, Bremen, Germany

Thesis: “Preparation and characterization of grafted adsorbents and their applications in biomolecule purification”.

Supervisor: Prof. Dr. Marcelo Fernández-Lahore.

Within this project, Hybrid Disposable Cartridges (HDC), a hybrid approach created by merging existing textile technology with Material/polymer chemistry was used to generate a cost-effective and disposable system supporting eco-friendly bioprocessing.

The goal here was to evaluate the performance of gPore NW materials, which can be functionalized and used to purify a range of bioproducts efficiently.

The further objective was to tailor the gPore NW system, which has already shown excellent results in the recovery and purification of natural as well as recombinant proteins, to other products, like pDNA or monoclonal antibodies.
