Andrea Rayat is Associate Professor in in Bioseparations and Downstream Processing at the Department of Biochemical Engineering at UCL. She is an associate member of the Institution of Chemical Engineers. She is the Chair of the Departmental Teaching Committee and is Programme Director of the undergraduate programme in Biochemical Engineering (BEng/MEng).

Previous and current roles:

  • Faculty Education Committee (2019-present)
  • Faculty Education Team (Covid Emergency Response, 2020-2021)
  • Covid19 Mitigation Coordinator (2020-2021)
  • BIA LeaP, BioIndustry Association Leadership Programme (2019-2021)
  • Department Safety Committee (2017-2019)

Andrea graduated from UCL with a PhD in Biochemical Engineering (2011). Her doctoral research focussed on the establishment of microscale bioprocessing platform for the evaluation of dead-end and cross-flow filtration operations and was used to study the impact of upstream conditions on filtration performance.

After her doctoral studies, Andrea worked in various capacities as product engineer, product manager and bioprocess consultant at a technical consulting firm offering software technology solutions and technical consulting for biopharmaceutical manufacturing businesses. Andrea managed the product development cycle and continous improvement for a process modeling software for modelling and evaluating bioprocesses, equipment and facility operation, and their associated costs. She worked on projects which included manufacture siting, capacity planning and concept studies for new-build or brown-field capital projects.

Andrea re-joined UCL as HEFCE Senior Enterprise Fellow in Bioprocessing in 2014 where she worked on technology translation, knowledge exchange, and the establishment of the commercialisation pathway for the first-generation ultra scale-down devices. With Prof Gary Lye, Andrea won a grant from the EPSRC Impact Acceleration Award (2016) for the establishment of commercial-ready USD devices. As a research staff, Andrea was part of the departmental committee for post-docs which organises seminars and workshops for their career development. One of these, Ideas to Impact workshop (2017), successfully obtained funding from the UCL Staff Development Programme. In 2018, she was appointed as Lecturer in Bioseparations (Downstream Processing) and promoted to Associate Professor in 2021.

Andrea obtained her MSc in Chemical Engineering and Biochemical Engineering (cum laude) from Delft University of Technology (TU Delft) in the Netherlands where she first specialised in downstream processing. She had her BSc in Chemical Engineering from the University of the Philippines in Laguna.

Research Groups
Research Summary

Andrea’s research area in bioseparations include filtration, centrifugation, other processes for cell harvest and primary recovery, and membrane filtration in downstream processing. She builds on the ultra scale-down (USD) approach, pioneered by UCL, which enables rapid understanding of bioprocesses and provides insights on robust manufacturing routes.

She continues to develop scale-down tools and apply high throughput techniques to evaluate such bioprocess performance, ultra scale-down membrane filtration for TFF evaluation, microscale TFF, and ultra scale-down centrifugation.

She is applying her expertise on downstream processing for different expression systems and biotech products such as mammalian cells to produce monoclonal antibodies and lentiviral vectors; and E.coli, yeast and other microbial systems for Fab fragments, enzymes or recombinant proteins. Most recently, this is applied to encapsulin production through a collaboration with VMIC (until 2021, this has now been taken on by an industry partner) led by colleague Dr Stefanie Frank.

Andrea has worked with Prof Mike Hoare, Davy Rowan and Biocatalysts Ltd. on a Knowledge Transfer Partnership funded by InnovateUK. This led to an IChemE Global Award 2020 in the Food and Drink Category and finalist in Biochemical Engineering Category. In 2021, the project was a Finalist in the Engineering Excellence Award in InnovateUK KTP Awards.

She currently collaborates with industry partners through EngD collaborations via the Centre for Doctoral Training in Bioprocess Leadership. Other collaborators are Prof Martina Micheletti (scale-down upstream/downstream), Dr Qasim Rafiq (LV production), Prof Dan Bracewell (impact of bioprocesses on DSP), Prof Gary Lye (continuous processing) and Dr Nav Gill (strategic partnerships and MBI programme).

In 2022, she received a BBSRC funding to study novel LV production systems with Dr Yasu Takeuchi at the Division of Infection and Immunity in UCL, and Dr Giada Mattiuzo at NIBSC in MHRA.

Teaching Summary
Andrea is Chair of the Departmental Teaching Committee and is Programme Director of the undergraduate programme in Biochemical Engineering (BEng/MEng). She works closely with the Departmental Tutor, Prof Martina Micheletti, and Deputy Head (Education), Prof Suzy Farid. She is a member of the departmental EDI and UGSSCC committees and the Faculty Education Committee at the Faculty of Engineering Sciences.

During the Covid-19 pandemic, Andrea was involved in the emergency response towards the end of Term 2 in 2019-2020 to move teaching delivery and assessments online. She has since served as the Covid-Mitigation Coordinator for the department and supported the Faculty Education Group for the 2020-21 planning and has led departmental efforts, together with the Education Leadership Team in the department of biochemical engineering, for the implementation of the Temporary Operating Model in 2020-21 and the move to Blended Learning for 2021-22 academic session.
