With an academic education in agricultural science and scientific experience in plant and microbial physiology, Christoph's main research area so far is best characterized as “(agro-)ecosystem physiology.” His work contributes to the understanding of resource fluxes in the plant-soil-atmosphere continuum and how these fluxes are influenced by environmental conditions. Of particular interest is (1) the efficiency with which plants use resources like carbon, nitrogen, water and light to build up photosynthate, the fuel of all life on Earth, and (2) the return of organic carbon back to the atmosphere as CO2 by respiration of plants and of soil microorganisms which feed on plant products.
