PERSONAL INFORMATION Citizenship: Brazil Phone: (530)758-4340 E-mail address: e-mail: stonettodefreitas@yahoo.com.br 2. EDUCATION 2006 Present Ph.D. Plant Biology, University of California, Davis, USA My research interests are to better understand the mechanisms involved in Ca ++ deficiency development in plants. The main hypothesis are that Ca ++ deficiency is not only triggered by total fruit Ca ++ content, but also by inadequate Ca ++ homeostasis in the cell. 2004 2006 M.Sc. Agronomy, Federal University of Santa Maria, Brazil The research was focused on the development of appropriate storage conditions to maintain high processing quality and delay physiological aging of potato tuber. 1999 2004 B.S. Agronomy, Federal University of Santa Maria, Brazil Associated with my B.S. in Agronomy, I worked with postharvest research of fruits, vegetables, flowers, and grains. 3. KNOWLEDGE OF LANGUAGES Understand and Read: Portuguese, English, Spanish, Italian Speak and Write: Portuguese, English
