Role
To apply specialist and leadership skills in managing Pathology laboratories.

To develop and adapt methods to enhance sugarcane disease detection and species identification.

Expertise
Molecular Biology and disease diagnostics, DNA isolation, Sanger Sequencing, Fungicide Screenings and Trials, Disease Isolation, NIR Technology, AFLP analysis, HPLC Analysis, Plant biotechnology, Mutagenesis, Plant physiology, Enzyme Kinetics and Tissue culture.
Research Interests

Molecular disease diagnostics, NIR data collection and building of disease models, detection and control of sugarcane rusts, sugarcane fungal diseases, conducting field trials and observation plots, using AFLP techniques to detect polymorphisms linked to disease tolerance.

Key Outcomes
Monitoring disease traps in place to detect current and new fungal diseases.

The expansion in the application of NIRS and HPLC for sugarcane.

Testing new chemical compounds against sugarcane diseases and conducting field trials towards product registration.

Disease isolation for use in screening trials.

Isolation and characterization of mutated genes that have increased tolerance to specific herbicides.
