Olena Vatamaniuk
Professor, School of Integrative Plant Science Plant Biology Section

Olena Vatamaniuk is Professor at the Soil and Crop Sciences Section and Plant Biology Section at Cornell University.
Olena obtained her bachelor’s degree in Botany at the Lviv State University (Ukraine) and Ph.D. in Plant Physiology at Lviv State and Kyiv State Universities (Ukraine). She did her postdoctoral studies in molecular biology, biochemistry and genetics at the University of Pennsylvania (PA, USA). She joined the Cornell faculty in 2005. In 2011, she was promoted to tenured Associate Professor and in 2019 to Full Professor.
The Vatamaniuk lab studies molecular mechanisms of mineral nutrient transport and its regulation. The lab uses multidisciplinary approaches including CRISPR/CAS9-mediated genome editing, scanning electron microscopy and synchrotron x-ray fluorescence imaging for the identification and characterization of genes controlling transition metal transport and its relationship to reproduction seed/grain yield and nutritional quality.

Interests
Functional genomics of mineral nutrient homeostasis
Toxic metal detoxification and phytoremediation
Biofortification
Recent Research
The Vatamaniuk lab studies molecular mechanisms of trace metal transport and its regulation in plants. We use multidisciplinary approaches including functional genetics, genomics, molecular physiology, and a variety of high precision analytical imaging tools to aid the identification of mechanisms controlling metal transport and utilization processes, metal sensing and signaling events in relationship to plant developmental programs, most specifically, fertility. We focus on essential micronutrients iron, copper, and an environmental toxin, cadmium, because of the importance of these elements for the future of food security and human nutrition and health. We use model plants, Arabidopsis thaliana, Brachypodium distachyon, and most recently grain crops, wheat and rice. Our ultimate goal is to contribute basic knowledge to the generation of novel biofortification strategies as well as improving grain yield and safety.
