Teaching

Teaching

My teaching is strongly influenced by research activities in molecular plant-microbe interactions, which promotes and embeds the research-led teaching in modules. I teach both UG and PG modules, supervise PhD, MRes and UG students, mentor post-docs and visiting researchers.

Modules   

BIOS2024 Infectious Agents and Allergens for second year UG students
MBIO4001 Research methods for MRes/MSc students   

 

Research

Research

Professor Tör has been working on the genetics and molecular biology of plant-pathogen interactions for over 25 years. He has worked on plant-oomycete interactions and made significant contributions to the mapping and cloning of several disease resistance and signalling genes in plants and effector genes in pathogens. He has also used his experience of molecular genetics in the cloning of fruit ripening genes such as CNR1 from tomato. He developed a research interest in innate immunity and explored this field with a cross section of scientists working on animal and human innate immunity.

Professor Tör joined the University of Worcester in 2010 and has continued to work on plant-pathogen interactions. Over the years, he has obtained funding from BBSRC, DEFRA, The Leverhulme Trust, ERA-NET, British Council and TUBITAK. He has mentored over 75 researchers, including post-docs, PhD students and visiting scientists.  

His current research interests are in the field of food security that include fundamental and translational research aspects. 

Key research areas include:

  • The role of circadian regulation in pathogenicity
  • Biological control of fungal pathogens
  • The role of small RNA in plant-microbe interactions
  • Genome editing for generating disease resistant plants
  • Use of genomics to accelerate plant breeding  

Current PhD studies

Osman Telli: Circadian regulations of effectors in the oomycete pathogen Hyaloperonospora arabidopsidis (Director of studies).

Catherine Jimenez-Quiros: Controlling mycotoxin producing fungal pathogen Fusarium graminearum using beneficial microorganisms (Director of studies).

Chris Norman: Deciphering the inter-kingdom RNA exchanges in the Alternaria-tomato pathosystem (Director of studies).
