I am Head of Growth at Low Carbon Materials (LCM), a green tech start-up/SME and Earthshot Prize Finalist (2022). We manufacture carbon negative aggregates to enable reduced embodied carbon in high emitting construction materials including asphalt and concrete. Net zero asphalt and concrete are a reality! I have been with LCM since November 2022. Before that I was a Professor of Chemistry at Durham University, where I had been an academic for 29 years.
