Harsh Bais is an associate professor of plant and soil interface at University of Delaware. Dr. Bais’ rhizosphere biology research is focused on the biological significance of root-mediated responses. Root-root and root-microbe communications are continues occurrences in the rhizosphere, but due to the underground nature of roots, these intriguing interactions have largely been overlooked. His research is taking a multi-disciplinary approach by interfacing plant biology, molecular microbiology and biochemistry to unravel this underground communication process.
