Research interests:

Research in my group centres around plant-pathogen interactions and the use of complementary imaging modalities in plant stress biology. We focus on (1) understanding the cellular and molecular basis of rice blast disease and (2) non-invasive image-based diagnosis of plant disease and stress biology.

Rice blast fungus (Magnaporthe oryzae) kills enough rice each year to feed 60 million people. We are working to understand the basic processes of infection and use molecular and imaging-based techniques. We routinely use minimally invasive methods such as chlorophyll fluorescence imaging and confocal microscopy, which is allows us to explore in detail and with sensitivity, mechanisms of infection. In addition, we use molecular genetic manipulation (including CRISPR-Cas9) and image-based and molecular diagnostic techniques, which gives a complete toolkit to pursue a research programme in the whole organism and cell biology of plant pathogen interactions. 

Ongoing projects in the lab are (1) The role of the circadian clock in rice blast disease (Ciaran Griffin, UoP studentship), which has shown the importance of both the plant and fungal circadian clocks in determining disease outcome; (2) Fluorescence imaging for Nutrition and Disease (FIND) (Dr Naofel Aljafer and Mrs. Angela Harrop, ERDF, INTERREG funded), which is using plant chlorophyll imaging to give pre-symptomatic diagnosis of plant disease, which has implications for agriculture (3) The role of the chloroplast in plant immunity (Kokila Wickramanayake Pathirannahalage, PhD student).
In addition to our core research in plant pathology, the laboratory is also engaged in several funded collaborative projects (see grants and contracts).

Supervised Research Degrees

I am currently advisor to 2 PhD students:

Mrs. Kokila Wickramanayake Pathirannahalage (https://www.plymouth.ac.uk/staff/kokila-wickramanayake-pathirannahalage) who is working on chloroplastic changes in response to pathogen challenge.

Ms. Peggy McGroary (https://www.rothamsted.ac.uk/people/peggy-mcgroary) who is working with Dr. Dana Macgregor on control of gene expression in weeds using VIGS and VOX.

 

Teaching

I enjoy teaching and have a particular interest in research-led teaching. I currently teach on several plant and molecular biology modules in all undergraduate stages and lead the final year module, BIOL301(Z) Plant Biotechnology: Lectures on plant biotechnology, synthetic biology. Workshops on socioeconomic and ethical aspects, gene mining and GM/GE strategy.
