In October 2015, she moved as a post- doctoral associate to Cornell University, US, where her research interests focused on the interaction of rice with its bacterial pathogen Xanthomonas and the role of transcription activator-like (TAL) effector proteins facilitating this interplay. In 2017 she started a post-doctoral position at the University of Cambridge, and is currently working on elucidating the spectrum of regulatory networks governing the evolution of C4 photosynthesis.

Sean Stevenson

Sean got his PhD from the University of Leeds where he studied abscisic acid (ABA) signalling in the model bryophyte Physcomitrella patens. This work identified a novel ABA regulator that was likely important in plant's conquest of land. After leaving the north for warmer climes, Sean joined the Hibberd lab at the start of 2017. He will be using another bryophyte model (Marchantia this time) to study light signalling and regulation and how this is integrated in early plant development and photosynthesis.

Ming-Tsung Louis Wu

Louis graduated from National Taiwan University with a Phd in Plant Science in 2015. His doctoral research focused on miRNA mediated regulation under oxidative stress in rice. In 2016, he started a post-doctoral position at the Institute of Plant and Microbial Biology of Academia Sinica where he studied the role of coilin protein in the alternative splicing of pre-mRNA in Arabidopsis thaliana. In 2017, he joined the Hibberd lab and is currently working on developing an analysis pipeline of de novo transcriptome to conduct a large-scale modeling analysis of C4 photosynthesis.

Andy Plackett

Andy did his PhD at Rothamsted Research (2007-2011), studying how the plant hormone gibberellin regulates floral and pollen development in the model flowering plant Arabidopsis thaliana. As a postdoc in jane Langdale’s lab at the University of Oxford (2011-2017) Andy worked to investigate the evolution of plant shoots, helping to establish a transgenic system for the candidate model fern Ceratopteris richardii via microparticle bombardment and then using this system to study the regulatory functions of the plant hormone auxin and the transcription factor LEAFY in the fern shoot. Andy joined the Hibberd lab in May 2017 as part of a project to understand the differential regulation of chloroplast development between mesophyll and bundle sheath cells in rice (Oryza sativa).

Patrick Dickinson

Patrick did his PhD with Phil Wigge at the Sainsbury Laboratory Cambridge University working on how plants sense temperature and how temperature is integrated with other environmental signals to control adaptive responses in Arabidopsis. This work found a role for chloroplast signalling in controlling diurnal patterns of thermotolerance. Since moving across Cambridge to the Hibberd lab in summer 2017, Patrick is working on how cell-type sepcific expression is controlled in Arabidopsis and how large increases in the expression of genes required for C4 photosynthesis have evolved using Arabidopsis and the C4 model species Gynandropsis gynandra.

Leonie Luginbuehl

Leonie did her PhD with Professor Giles Oldroyd at the John Innes Centre in Norwich, where she investigated the downstream transcriptional targets of three GRAS-domain transcription factors required for the establishment of the arbuscular mycorrhizal symbiosis in the model legume Medicago truncatula. Her work identified a lipid biosynthesis pathway that is upregulated in root cells colonized by arbuscular mycorrhizal fungi and provides the obligate biotrophic fungus with fatty acids as a major carbon source. In November 2017, Leonie joined the Hibberd lab as a postdoctoral scientist. Her research focuses on understanding the cell type specific regulation of photosynthetic capacity in rice leaves.

Specifically regions of the rice and sorghum genomes that are bound by transcription factors as leaves develop.

PhD students

Greg Reeves

Greg has a BSc in Genetics and MSc in Horticulture both from New Mexico State University where he studied the inheritance of disease resistance and spicy flavour in chilli peppers. He discovered a new gene that inhibits disease resistance, helped sequence the chilli pepper genome and developed one of the hottest peppers in the world. Additionally, he helped identify novel genes involved in photosynthesis from large-scale mutant screening in green algae at the Carnegie Institute for Science, Stanford. At Cambridge, he is investigating the genetic basis for C4 photosynthesis from natural variation among C4 plants and traditional gene mapping approaches to identify which genes are involved in developing the C4 pathway.

Robyn Phillips

Zheng-Ao Di

Zhengao got a BSc in Chemistry from Nankai University, China, in 2016. After graduation, he took an intern in Shanghai Institute of Plant Physiology & Ecology for 6 months investigating the functional targets of secondary metabolites by chemical proteomics. Zhengao joined the Hibberd lab in Sep 2017 as a PhD student. He is now studying how modifications to the spatial organisation of metabolic pathways can be used to manipulate their efficiency in two complementary strands of research. In the first, he aims to better understand how assembly of synthetic protein scaffolds affects pathway efficiency in plants. In the second, he aims to increase the distance between enzymes of photosynthesis by engineering a synthetic C4 cycle in leaves of C3 A. thaliana.

Conor Simpson

Conor is a BBSRC DTP student. He graduated with an MSci from the University of Nottingham. For his masters project at Nottingham he worked on the N-end rule pathway of programmed protein degradation. Currently, through exploiting the natural variation in the C4 species Gynanropsis gynandra, Conor is using specific breeding methods in conjunction with quantitative genetics to calculate the heritability and number of genes responsible for certain C4 characteristics. Additionally, with the aim of identifying loci responsible for complex C4 phenotypes, such as Kranz anatomy, he is using quantitative trait loci (QTL) analysis to generate a high-density genetic map in G. gynandra.
