Field of Research: Postharvest Phytopathology

Research interests:
• Postharvest disease control
• Fruit-pathogen interactions
• Fungal physiology

Methods used:
Mycology, Molecular microbiology, Transcriptomics, Proteomics, Metabolomics, Bioinformatics, Microscopy and Biochemistry.

Ongoing projects

1.  Uncovering the molecular basis for chilling tolerance of the phytopathogenic fungi Botrytis cinerea and Alternaria alternata.

2. The effect of postharvest handling on nutritional values of acorn squash fruits.

3. Evaluating the effect of pre- and post- harvest treatments on long term storage of pumpkins.

4. Evaluating the effect of calcium spraying on fruit quality, susceptibility to gray mold disease and shelf life of pepper fruit.

5. Uncovering to cause of pumpkins fruit rot during storage and determining the effect of viruses on fruit susceptibility to fruit rot disease
