Senior Scientific Assistant
After completing his degree in Biology, Mark continued doing a PhD in Plant Physiology in the group of Luit de Kok at the University of Groningen, The Netherlands. His research interests were the regulation of plant sulphur metabolism and in particular the impact of atmospheric and pedospheric sulphur nutrition on the uptake and assimilation of sulphate. His interest in sulphur metabolism led him to the group of Stan Kopriva at the John Innes Centre, Norwich, UK, where he did a short postdoc on molecular aspects of the regulation of nutrient uptake.
In 2007, Mark moved to Rothamsted to do a short postdoc on nitrogen remobilization in Miscanthus, as part of the Supergen project, in Malcolm Hawkesford's group. In September 2008, he started his current project in Phil Brookes' group on the impact of biochar on microbial biomass, also part of Supergen. Different types of biochar and bio-oil, enriched with nitrogen, will be tested for their use as a slow release fertilizer.
