Research overview

From September 2022 I'll be taking up a Lecturer position within LEC to continue the work mentioned below, in addition to new plant engineering work.

My work centres on the central enzyme of photosynthesis, Rubisco (Ribulose 1,5-bisphosphate carboxylase/oxygenase). As the gatekeeper of carbon entry into the biosphere, Rubisco serves the critical role of assimilating carbon from atmospheric CO
2 for the plant to use in growth. However, Rubisco has undesirable characteristics which make it a major rate-limiter of photosynthesis, particularly in crop plants. Currently I am focused on two main areas, we are collaborating with colleagues to investigate the incorporation of cyanobacterial carbon concentrating mechanisms into higher plants as a means to overcome some of Rubiscos shortcomings and boost plant productivity. And as part of RIPE: Realizing Increased Photosynthetic Efficiency, we are investigating Rubisco diversity and it's regulation during rapid changes in conditions.

Current Research

My current research contributes to projects studying the implementation of a cyanobacterial CCM into higher plants, Rubisco catalytic diversity, and Rubisco regulation under fluctuating conditions.

I am working with  Martin Parry and Elizabete Carmo-Silva, as well as other members of the photosynthesis team here at LEC.  I also have and am part of active collaborations with colleagues at the University of Illinois, Cornell University, University of Edinburgh, USDA-ARS, ITQB-Nova Lisboa, UC-Davis and others.

As part of the Potosynthesis group at LEC I also contribute to disseminating our research through managing the website and twitter of the group.
