Dr. Heyl works on the evolution and function of signaling pathways. In particular he is interested in the origin and in the molecular mechanisms of the signal transduction pathway of a class of plant hormones called cytokinins. Wet lab experiments and bioinformatics analysis tools are used towards these goals.
