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
