Sonali Roy obtained her PhD. at the John Innes Centre in Norwich, UK investigating the role of the phytohormone auxin in symbiotic nitrogen fixation. She continues her research interests in signalling molecules during her post-doctoral appointment in Dr. Udvardi’s lab at the Samuel Roberts Noble Foundation where she examines the role of small signalling peptides in symbiotic interactions. In addition to investigative research, Sonali particularly enjoys mentoring and providing hands-on training to plant and molecular bioscience students.
