Sivamathini Rajappa

Dr. Sivamathini Rajappa is a Postdoctoral Research Fellow at the National University of Singapore (NUS), working at the interface of plant biology and nanotechnology under the supervision of Prof. Tedrick Thomas Salim Lew. Her research focuses on developing biomimetic nanotechnology approaches to improve plant resilience to environmental stresses, particularly salinity, and to design nanoparticle-based delivery systems for plant biotechnology and biosensing applications. She obtained her Ph.D. in Biological Sciences (Plant Biology) from NUS, where her research on molecular characterization of ion transporters involved in plant salt tolerance earned her the Gold Medal for the Best PhD Thesis awarded by the International Society of Plant Molecular Biology. She previously worked as a Postdoctoral Research Fellow at Seoul National University, South Korea, studying molecular mechanisms regulating xylem development in Arabidopsis. Her research integrates molecular biology, plant physiology, abiotic stress and nanotechnology, and she has published in leading journals including two papers in Nature Communications, as well as Nanoscale, Frontiers in Plant Science, and Plant Cell Reports. She is also actively involved in mentoring students and contributing to interdisciplinary research aimed at advancing sustainable agriculture.
