He has 14 published papers in international and peer reviewed Journals, in which 6 out of 14 is the first author. He also has 22 published peer-reviewed abstracts in international congresses, in which 14 out of 22 is the first author. In total, he has participated in 16 research programs funded by several companies, European consortiums, and the Flemish Association of Pig Farmers.
His research work is focused on the translational/applied research that aims to improve the health, the productivity and the welfare of pigs, with an emphasis on translational physiology. He has conducted research about improving the efficacy of the vaccines against Mycoplasma hyopneumoniae, which is the main etiological agent of enzootic pneumonia in pigs. In this context, he studied the role of T-lymphocytes in the evolution of respiratory disease in pigs, but also the differences in the immune and pro-inflammatory responses detected between vaccinated and unvaccinated pigs in farms endemically infected with Mycoplasma hyopneumoniae. He has also studied the use of autogenous vaccines in sows for the control of exudative epidermitis in their progeny during the nursery phase, and also, the fertility of the boars in relation to the carcass quality parameters that can pass over to their progeny. He has also conducted studies that concern the use of different feed additives and their effect on the health and the productivity of the fattening pigs, as well as the supplementation of different levels of iron (ferrous sulphate) through the feed for the prevention of iron deficiency anaemia. Additionally, the supplementation of pig diets with the enzyme of b-mannanase for the better metabolism of corn in fattening pigs. Finally, he has conducted thousands of welfare assessments at pig farms, for the official audits concerning sows and fattening pigs in the context of farm assurance schemes for the accreditation of pork abiding with the highest welfare standards.
