Emeritus Professor. Ted’s main interest is functional anatomy. He holds an NRF “B” rating. His research involves studies of plant structure and function, the effect of long-term elevated CO2 on uptake and loading of photoassimilates in leaves under controlled environment, cell to cell transport in plants using techniques involving light, electron, fluotescence and confocal microscopy – mostly involving molecular probes. His research interests also encompass studies of the long-term effects of aphid and other suctorial insects feeding on the transport systems in leaves at the cellular and molecular level.
