Teaching and Research Activities

Andrea is a tutor in Integrated Downstream Processing Module, MSc Design Projects and MEng Research Projects. She also supports the Ultra scale-down (USD) Scenario Week for second year biochemical engineering undergraduates. She will soon teach Design of Experiments for postgraduate students and facilitate the same MBI module. 

Andrea has been involved in delivering lectures for MBI training modules since 2011. These modules are MBI Bioprocess Design and Economics, MBI Bioprocess Facility Design and MBI Vaccines Development. Most recently, she contributes to the MBI modules in Primary Recovery (MBI Cell to Column) and Quality by Design. 

In her role as tech transfer lead for ultra scale-down  technologies, she established training on kompAsTM shear device and ultra scale-down filtration. She engages with end-user biopharmaceutical or biotech companies to deliver training on ultra scale-down bioprocessing using kompAsTM.
