Our team of life science experts

Dr. David Weinkove
Biologist, CEO

David’s role within Magnitude is as our lead consultant to diagnose customer challenges, determine where our expertise and services can best progress your research project, and ensure customer projects deliver the required value and answer the key research questions, from project start to finish and beyond. Dave and the rest of the team ensure that customers can take the results of their study with confidence to their stakeholders and investors to help inform their research and business decisions.

David is the Chair of the British Society for Research on Ageing (BSRA). David is also an Associate Professor at the Department of Biosciences, Durham University, and obtained a PhD in biochemistry from University College London and a B.A from the University of Cambridge. David also trained at UCL, MRC Laboratory for Molecular Cell Biology, Ludwig Institute for Cancer Research, Netherlands Cancer Institute, Hubrecht Institute, University of Utah. David has published 20 peer reviewed papers and has over 3000 citations of his work.

David has a particular interest in the field of geroscience, with experience identifying compounds that are effective in slowing ageing and showing the route to target identification to allow them to progress drugs to the next stage of the preclinical pathway and receive support from investors. Additionally, David has experience quantifying acute and reproductive toxicity of key components used by large consumer goods manufacturers as well as assessing the health benefits of probiotics or microbes.

In addition to being a thought leader in C. elegans research for over 20 years, David has broad knowledge and extensive practical experience in many fields in biological sciences.

David discovered a mutation in the E. coli bacteria that increases C. elegans lifespan (Virk et al 2012) and has characterised a number of compounds that slow ageing (Bass et al 2007, Virk et al 2012, Cabreiro et al 2013). He led a manual screen of 1000 E. coli mutants to find those that increase lifespan (Virk et al 2016) and development of a defined nutrient media to increase reproducibility (Maynard et al 2018). As a postdoc, he worked with David Gems, Ronald Plasterk and Erik Jorgensen.

To improve throughput and data quality, David has turned to automation. He brought together the Magnitude Biosciences team as the right people to design, implement and deliver a reliable automated service that can bring increases in productivity to the whole field.
