I am a Brazilian Biologist interested in understanding the physiological mechanisms that underlie the Selenium hyperaccumulation in plants. I am especially interested in how the Stanleya pinnata (Brassicaceae) is able to distinguish Selenate (Se) from Sulfate and preferentially accumulates Se up to 0.5% of its dry weight. This research will improve our understanding of plant Se metabolism, with important implications in the fields of agriculture, medicine, and industry. I received my undergraduate and Master of Science degrees from the São Paulo State University (UNESP-Jaboticabal) in 2010 and 2014, respectively. My previous work focused on the effects of Se on plant metal stress resistance.
