Biology turns engineering

As we reach the “read/write” stage of biology, evolution is proving to be the ultimate algorithm, allowing us to increasingly program biological systems. A foundational shift in biology from being an empirical science towards becoming an engineered discipline is underway.

Mark Kotter

MD, PhD, Founder/CEO

Mark is a stem cell biologist and neurosurgeon at the University of Cambridge. By combining synthetic and stem cell biology, his team has developed a benchmark technology for the efficient and consistent production of human cells for use in research, drug development, and cell therapy. He is the founder of bit.bio and co-founder of the cultured meat startup Meatable.

Paul Morrill

PhD, Chief Business Officer

Paul is a serial entrepreneur and scientist with over thirty years of experience in the biotech and pharma sectors.  Most recently, he was the commercial founder and President of Horizon Discovery Group, and founder of CellRx Limited, a growth factors company serving the biopharmaceutical sector. Paul holds a PhD in Biotechnology from the University of Cambridge.

Roger Pedersen

PhD, Chief Scientific Advisor

Roger is a pioneer and thought leader in the field of human stem cell biology. His lab was the first to isolate pluripotent epiblast stem cells from the epiblast layer of the developing mammalian embryo. In addition, he developed one of the first cellular reprogramming protocols. Roger was co-founder of the Cambridge Stem Cell Institute. His lab is currently focused on differentiation of pluripotent stem cells, with potential applications for drug discovery, toxicity testing and cell therapies.

Florian Schuster


Florian is an active entrepreneur and investor. He is the co-founder of bit.bio. Previously, he was CFO & Head of Strategic Partnerships for Tessa Therapeutics, a clinical-stage cell therapy company. Florian is a former investment banker, a graduate of the Stanford School of Engineering, and an alumnus of Harvard Business School.

Marius Wernig

 PhD, SAB Member

Marius’ seminal 2010 paper in Nature demonstrating direct conversion of fibroblasts into neurons has sparked a widespread interest in cell reprogramming. He is the co-director of the Stanford Stem Cell Institute. His lab uses cellular reprogramming to understand how neurons are induced, and how they mature and maintain their identity.

Bit.Bio: British firm cracks code for stem cells

Published on The Times.

Now a British company, Bit.Bio, has received £40m of backing for technology that it claims can reliably reprogram stem cells, producing a cellular vending machine to make any human cell you desire.

Published on Endpoints News.

Mark Kotter’s synthetic biology team at Bit Bio has already won lots of local recognition in the UK for its tech for precision reprogramming of stem cells at an industrial scale. Now they have a jolt of cash from some marquee US investors to fuel the work and drive some added global panache for the biotech’s profile.
