Dr. Zoltán Kis is a Senior Lecturer (Associate Professor) at the Department of Chemical and Biological Engineering at the University of Sheffield, and an Honorary Lecturer at the Department of Chemical Engineering, Imperial College London.

Zoltán is leading a multidisciplinary team that is innovating and digitalising RNA vaccine and therapeutics production platform technologies. His work is addressing the challenges of producing large volumes of RNA-based vaccines and therapeutics, rapidly, at high quality and at low cost in a disease-agnostic manner.

He is regularly invited to speak at scientific and industry conferences, and to advise policy experts, non-governmental organisations and companies. For example, he was consulted for techno-economic modelling by the WHO mRNA Technology Transfer Hub, and he sits on the Sanofi mRNA CMC Advisory Board as well as the Pfizer mRNA technology Advisory Board.

Zoltán’s work on RNA vaccine manufacturing and production process modelling received high-profile media coverage in the UK and internationally e.g. on BBC World News, BBC Radio (4,5 and World Series), Sky News, RTL TV, China Central Television (CCTV), Nature News, The Lancet, BMJ, CNN, The Wall Street Journal, Financial Times, The New York Times and many more.

Zoltán obtained his Ph.D. in Bioengineering from Imperial College London, UK, holds an M.Sc. in Applied Biotechnology and a B.Eng. in Chemical with Biochemical Engineering.

Research interests


Our exciting research combines experimental and modelling techniques, and innovates RNA vaccine & therapeutics production platform processes. The platform processes that we are developing will enable the rapid development and mass-manufacturing of RNA vaccines and therapeutics at high volumes, low cost and high quality against a wide range of diseases. To achieve this ambitious goal, we are developing and synergising a set of physical and digital technologies integrated into the Quality by Digital Design framework, and based on techno-economic considerations. The obtained computer models will link RNA product quality to the production process, and will enhance both the development and operation of RNA manufacturing processes.

The RNA vaccine platform technology has been successfully used to develop COVID-19 vaccines at record speeds. However, the RNA vaccine production volumes and rates can be further increased, while reducing costs and maintaining consistently high product quality. In addition, RNA vaccines can be produced based on a transformative platform technology, meaning that the same manufacturing infrastructure can be used to produce vaccines and therapeutics against a wide range of diseases. Therefore, it is anticipated that the demand for RNA vaccine production technologies will substantially increase and the physical processes and digital tools developed in our group are expected to be widely adopted.

Key research areas include:

  • Experimental mRNA vaccine and RNA therapeutics manufacturing process development: process intensification, continuous manufacturing and scale-up.
  • Development and optimisation of continuous in vitro transcription (IVT) reaction for mRNA synthesis, continuous mRNA downstream purification processes based on continuous chromatography and tangential flow filtration unit operations, as well as continuous LNP formulation unit operations.
  • Development of new unit operations and design of process equipment for mRNA manufacturing.
  • Process digitalisation: development of soft sensors and digital twins to monitor and control the manufacturing of RNA vaccines, RNA therapeutics and other biopharmaceuticals.
  • Techno-economic modelling for reducing the costs, increasing production rates and increasing production volumes of RNA vaccines, RNA therapeutics and other biopharmaceuticals.
  • Quality by Digital Design for consistently ensuring product quality, support scale-up, technology transfer, and for accelerating the regulatory approval process.


We are eager to support talented individuals who are passionate about biomanufacturing, production process development, process analytical technologies, RNA vaccines and therapeutics, as well as process modelling, digitalisation, machine learning and Industry 4.0.

Prospective PhD students, post-doctoral researchers and research fellows are encouraged to send me a brief expression of interest (e.g. up to 1 page) along with their CV.
