Founded in 2018 as a spinout from the University of Oxford, by co-founders Alex Greenhalgh, Martin Frydrych and Fritz Vollrath, Spintex has consistently been pushing the boundaries of our bioinspired spinning and silk materials to provide much needed solution in sustainable and technical textiles.

Our Team


Alexander Greenhalgh

CEO & Co-Founder

Biologist and programmer with a six-year working background in microbiology, clinical trials, silk and protein science. Research Assistant in the Oxford Silk Group for the last three-years under an ASFOR grant. Particular experience in clinical trials, with a focus on GCP compliance. Research experience includes characterisation of liquid silks and fibres with techniques such as rheology, fluorimetry, calorimetry, electrophoresis and tensile testing.


Martin Frydrych, PhD

CSO & Co-Founder

Material scientist & engineer with over 10-year background in natural and synthetic polymers, and expert in various polymer-based fabrication techniques. Expertise in plastic engineering and in the research & development of biocompatible & biodegradable polymer materials.


Yue Jin Oh, PhD

Research Engineer

Biologist with seven years of silk research experience. His PhD involved developing novel techniques for studying spider silks through silk modification and by application of multi-spectral techniques. Expertise in silk protein science, unnatural amino acid incorporation, bioimaging, organic synthesis, materials testing, experimental design, and various spectroscopic techniques.


Amanda Schmidt

PhD Candidate & Research Assistant

Mechanical Engineer PhD candidate under the Biobased Value Circle, Horizon 2020 Marie Skłodowska-Curie Actions Grant. Experience in Biomaterials and Biopolymers for advanced applications. 


Fritz Vollrath, Prof.

Scientific Advisor

Leads the Oxford Silk Group at the University of Oxford and has over 250 papers on the structure, biochemistry and biophysics of silk with a research team well positioned at the forefront of international silk research. He has successfully acquired continuous funding from sources such as the ERC, ASFOR and The Royal Society.


Chris Holland, PhD

Scientific Advisor

Head of the Natural Materials Group at the University of Sheffield and a Senior Lecturer in the Department of Materials Science and Engineering. With over sixteen-years of experience in silk and natural materials research, he has established himself as one of the leading researchers in the field of silk rheology, addressing the fundamental question of how silks are spun. He is also Chair of the IOM3 Natural Materials Association, Associate Editor for ACS Biomaterials Science and Engineering and was the Lead-Coordinator of the H2020 FET OPEN project FLIPT.


Robert Harrison, PhD

IP Advisor

European Patent Attorney with almost 30 years’ experience in business development and intellectual property. He is focusing on developing intellectual property portfolios and commercialisation strategies for start-ups and small and medium-sized businesses.
