Her primary research interests are in understanding the role of lipid-mediated signaling in plant responses to environmental signals and stress, with the long term goal of improving plant growth under unfavorable conditions. She has been involved in plant gravitational biology research since her postdoctoral work, and she has been a principal investigator on NASA-funded ground-based research since 2001. Currently, Perera is the principal investigator on a spaceflight project entitled “Plant Signaling in Microgravity” to characterize the molecular mechanisms of plant responses to microgravity that was conducted aboard the International Space Station in 2011.
