Prof. Dr.

Uwe Rascher is head of the research area ‘Shoot Dynamics’ at the Institute of Bio- and Geosciences at Forschungszentrum Jülich. Additionally, he is Professor for ‘Quantitative Crop Physiology’ at Bonn University. In his research he combines concepts and knowledge of plant physiology, remote sensing, ecology, global climate change and plant phenotyping. His main expertise is in characterizing photosynthesis using chlorophyll fluorescence, hyperspectral reflectance, gas-exchange, remote sensing and image analysis techniques. In the frame of several interdisciplinary and international collaborations he is using novel remote sensing approaches to better measure photosynthesis and stress, develops novel plant phenotyping concepts, and uses these data to model plant mediated exchange processes from the leaf to the region. This knowledge is applied for a wide range of crops and management systems, including cassava.
Within the cassava source-sink project the group of Uwe Rascher developed a novel UAV based approach to map the 3-dimensional growth dynamics of large cassava fields and they will now move forward to quantify the seasonal dynamics of photosynthetic carbon gain in different cassava lines under the prevailing changing environmental conditions.

Dr.

Anna Magdalena van Doorn is a Postdoctoral researcher in the shoot dynamics group of Uwe Rascher at the Institute for Bio and Geosciences of Forschungszentrum Jülich. She is developing methods to quantify canopy structure of cassava field trials with the use of aerial imaging and Structure from Motion. She is using UAV-based field phenotyping techniques to investigate the different seasonal behaviour of various cassava varieties. In the CASS project she is using these techniques to help understand the functional differences in canopy structure and relate these to functional traits.

Kelvin Acebron

Kelvin Acebron is a PhD student at the Forschungszentrum Jülich, Germany. His study focuses on understanding the temporal dynamics of photosynthesis in a leaf level using Solar-Induced Fluorescence (SIF). This involves understanding the mechanistic link between Solar-Induced Fluorescence (SIF) and Photochemistry as affected by different physiological mechanisms of Non Photochemical Quenching (NPQ). The first part of his research was focused on a model plant Arabidopsis thaliana having specific mutations in NPQ.  He then decided to transfer from a model plant to Cassava crop to focus on understanding the NPQ adjustments in fluctuating light as well as its consequence on photosynthesis and SIF signal.
