¹û½´ÊÓƵ

Personal: I grew up in India where I completed Ph.D. in Mycology and Plant Pathology at the Banaras Hindu University (). BHU is located in one of the oldest cities in India, Varanasi (Banaras). The history of the city dates back, at least, 3000 years! I then carried out post doctoral training at McGill University and Colorado State University. I arrived at ¹û½´ÊÓƵ Agricultural Campus in 2005.

Research: I lead two research programs; 1. Molecular plant-microbe interaction – investigating the genetic basis of plant root-microbe interaction and 2. Plant biostimulants – discovery and mode of action of seaweed and microbial based plant biostimulants. Our research group was one of the first to investigate the molecular mechanism(s) of action of seaweed-based plant biostimulants. I extensively collaborate with industry. Some of the technologies we developed are now licensed by Agri-biotech companies. I have published more than 130 peer reviewed publications and supervised 15 Post-doctoral Fellows, 23 Graduate Students and 23 Undergraduate Students and Research Associates.

International: I believe a strong international partnership is central to solving global agricultural problems and to improve food and nutritional security. In my current role as Assistant Dean International, I oversee and support Faculty of Agriculture international engagement including international development projects, partnership with Universities and institutes around the globe and as well promote international student mobility. I was fortune to participate in several funded international research projects in Brazil, India and France. Besides, I maintain a productive research partnership with colleagues in the UK, Ireland, Japan, Australia, China, Philippines and USA. I have also hosted a number of international students from Brazil, China, France, Iraq, Sri Lanka and India in my lab.
