Dr Sylvaine Aubry


Mr Seong Jin (Leon) Baek was a Postgraduate student. Leon was investigating the effects of sugars on the circadian clock.


Helen Briggs was a BBSRC - funded technician working with Dr Fiona Robertson to investigate the transcriptional network associated with circadian [Ca2+]cyt oscillations.


Dr Naomi Brown was a BBSRC funded postdoctoral research associate who was investigating the mechanisms by which the circadian clock regulates chlorophyll accumulation. Naomi worked in collaboration with Julian Hibberd.


Dr Guy-Bart Stan was an EPSRC funded postdoctoral research associate who was based in the Gonçalves laboratory in the Department of Engineering. Guy was investigating robustness of circadian oscillators.


Katharine Hubbard was a Ph.D. student funded by a BBSRC studentship. She was performing epistatic analysis of circadian signal transduction.


Dr Antony Dodd Dr Antony Dodd was a post doctorial research associated funded by the BBSRC to investigate the mechanisms of generation of circadian oscillations of cytosolic free calcium. This was a collaboration with Prof. Dale Sanders FRS University of York. Antony now holds a Royal Society University Research Fellowship at the University of York.


Carlos Hotta was a Ph.D. student funded by the Brazilian government to investigate the mechanisms that generate circadian calcium oscillations.


Dr Mia Jakobsen was a Post Doctoral Research Fellow funded by the Danish government. She was investigating the mechanisms by which time-of-day modulates cold signal transduction.


Angela Donoghue was an underPostgraduate honours student carrying out research on the mechanisms by which the circadian clock increases chlorophyll content. This was a collaboration with Prof. Julian Hibberd.


Jean-Maurice Assie was a BBSRC-funded technician working on the mechanisms by which the circadian clock regulates cytosolic free calcium.


Fran Tracy has just finished her Ph.D. funded by the BBSRC to investigate the role of calcium oscillations in salt stress. This was a collaboration with Prof Mark Tester.


Nandita Garud was a summer intern from New York who investigated light regulated calcium signalling.


Andrew Baker Andrew was a Postgraduate student funded by a BBSRC Committee Studentship. He was identifying genes involved in the specialised function of stomatal guard cells.


Dr John Love John held a Broodbank Fellowship from November 2001 to September 2003 to study calcium signalling during photoperiodic responses in Arabidopsis. John is now a lecturer at the University of Exeter.


Anja Telzerow and Bianca Ulitzsch spent the summer 2003 training as technicians in the laboratory.


Landry Bertaux Landry visited from France in the Summer 2003 to investigate the response of guard cells to cold shock.


Suiwen Hou Suiwen is a Postgraduate student. He carried out research in the signal transduction laboratory during 2002. He is from Lanzhou University, China. He was characterising genes flanking enhancer trap T-DNA inserts in a guard cell enhancer trap line.


Alexander Ducke and also Melanie Klose spent their summer in the Signal Transduction lab training as research technicians. Alex and Melanie are from Germany.


Peter McKeown Peter has just finished his underPostgraduate project in the lab. He was identifying genes expressed in the guard cell using RT-PCR.


Claire Mennim Claire was a Nuffield Foundation Summer Student. She was studying calcium dynamics in guard cells using aequorin.


Laure Barrot Laure was visiting the lab from The Ecole Nationale Superieure Agronomique de Rennes. She was making transgenic Arabidopsis in which calcium-sensitive proteins are targeted to the guard cell.


Naomi Forrester Naomi was a Wellcome Trust Summer Student. She studied the circadian regulation of the Cab2 promoter in guard cells.






Prof. Dale Sanders University of York) and Prof. Julie Gray (University of Sheffield) collaborate with the signal transduction lab to investigate the role of cADPR in circadian behaviour.

We collaborate with Prof. Jim Haseloff (University of Cambridge) and Prof. Scott Poethig (University of Pennsylvania) to identify guard cell genes and enhancer elements.

Prof. Carl Johnson (Vanderbilt University) also investigates circadian calcium signalling. We are collaborating with his group to investigate cell-specific circadian behaviour.

The Department has carried out a comprehensive COVID-19 risk assessment process and has opened to allow research work to take place. To ensure the safety of our staff, a range of measures to reduce building occupancy and allow strict social distancing have been introduced, including increased cleaning and hygiene regimes.
