Expertise:

Christian Dimkpa has 25 years of pre -and post- doctoral engagement in plant-environmental sciences with strong nexus with chemicals. Since 2009, he has been involved in agricultural and environmental nanoscience research, including plant and microbial nanotoxicology, development of enhanced efficiency chemical fertilizers based on coating with nanoparticles, and studies of plant beneficial responses to mineral nutrients as a function of particle size (nano and bulk) and solubility state. He has expertise in investigating crop response to differently packaged micronutrients (zinc, copper, boron, iron and manganese) for yield enhancement, acceleration of phenological development, resilience to drought and disease stress, and fortification of edible tissues with nutrients critical for human health. He also studies the role of micronutrients in improving plant use efficiency of nitrogen, with implications for mitigating nutrient loss and associated climatic effects. An important aspect of Christian’s expertise involves examining how micronutrients influence plant uptake of phosphorus. Experience prior to 2009 include serving as a Technician and Supervisor in banana crop improvement research. He has published over 75 journal articles, book chapters and technical reports. He has given presentations and attended national and international conferences/workshops in multiple countries, including United States, Germany, Belgium, Canada, China, Brazil, Uganda, Kenya, India, Myanmar, Nigeria and Morocco.
