Professor Pathmanathan Umaharan

Professor Pathmanathan Umaharan - Head, Cocoa Research CentreHead, Cocoa Research Centre/ Professor in Genetics.

Responsible for policy, strategic direction and governance of the Cocoa Research Centre, in addition to curation of the genebank and outreach.

Area of expertise

Plant genetic resources management, genetic analysis and crop improvement. Experience in working with cocoa, Anthurium, hot pepper, tomato, cowpea, and pigeon pea, specifically with respect to genetic resistance to pest and diseases, yield and yield components as well as quality traits. Other areas of interest include biotechnology and biosafety.

Current research interests are understanding host-pathogen interactions and genetics of resistance in cocoa and Anthurium; genetic resource management in cacao and hot pepper as well as biotechnological approaches to improving the colour range in Anthurium.
