My research interest is to understand how plants control growth and development to improve adaptation in response to environmental changes. Plants have evolved with adaptive responses to perceive environmental changes and integrate these external signals with their internal developmental programs to optimize growth and improve survival throughout the whole life cycle. My research is primarily focused on understanding the genetic and molecular mechanisms to control plant growth and chloroplast development through light signaling pathways in response to light and abiotic stresses using a combination of genetics, molecular biology, cell biology, biochemistry, and genomics. The ultimate goal of my research is to improve agricultural productivity and sustainability by developing climate-resilient crop plants.
