3. Science communication - Science and
Literature
Assistant Professor of Plant
Biology. He received his M.A. in Biology and his Ph.D in Plant Physiology from
the University of Bari, and followed that with postdoctoral positions at the
University of Kassel (Germany), the Vrije Universiteit Amsterdam (The
Netherlands) and the University of London, Royal Holloway College (Egham, UK).
In 2007 he was a Fulbright Visiting Scholar at the University of
California–Berkeley, where he worked on the role of ascorbic acid
(vitamin C) in the redox regulation of plant development.
Currently, teaches classes in Plant
Biology, Plant Morphology and Physiology, Plant Biotechnology, Phycology, Plant
Developmental Biology, Techniques in Plant Biology, and Science Teaching. His interest
in science communication is a consequence of the continuing debate on the
necessity of developing new teaching tools.
Manuscript reviewer for several
journals, Editor-in-Chief of Plant Physiology and Biochemistry. Lead Editor of Nature Education - Topic room on Cell Origins and Metabolism
