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

Andrea‚Äôs research area in bioseparations covers 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. 

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 for Biopharm Services, a company offering software technology solutions and technical consulting for biopharmaceutical manufacturing businesses. She was a Product Manager (2011-2013) and Product Engineer (2011-2014) for their software, called BioSolve. She managed development updates for this tool and contributed to the creation of its various new functionalities for modelling and evaluating bioprocesses, equipment and facility operation, and their associated costs. As a bioprocess consultant (2012-2014), Andrea delivered training on bioprocess and cost modelling and worked on projects which included manufacture siting, capacity planning and concept studies for new-build or brown-field capital projects. She developed business cases and value proposition of new bioprocess technologies through process and economic modelling.

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 and Dr Alex Chatel, Andrea won a grant from the EPSRC Impact Acceleration Award (2016) for the establishment of commercial-ready USD devices. She led (with Prof Gary Lye) the licensing of the USD technologies to a UCL spin-out company in 2018. 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.

Before coming to the UK, Andrea was a faculty member at the Department of Chemical Engineering at University of San Carlos in Cebu City, Philippines. She taught chemical engineering subjects such as separation processes and transport phenomena and contributed in academic administration as coordinator for graduate programmes, undergraduate research and departmental finance. Her research then was on the (bio)conversion of wastes and low-value by-products from food processing and from plant-oil refining.

Andrea had her MSc in Chemical Engineering and Biochemical Engineering (cum laude) from Delft University of Technology in the Netherlands where she first specialised in downstream processing. She obtained her BSc in Chemical Engineering from the University of the Philippines in Laguna where she first experienced how to design and evaluate a unit operation for her undergraduate thesis.
