PhD 1992 in Plant Physiology.

Main topics of research

The plant plasma membrane contains an activity capable of transferring electrons from the cytoplasmic face of the membrane to the apolast. While such an activity seems to be present in all plant tissues, no clear evidence of its purpose exists.
Besides research on the biochemical and biophysical characteristics of the electron transport system investigation of plant plasma membrane energization and nutrient uptake is another topic of my work.
