My research focuses on environmental law, primarily on the special part of environmental law, in the field of special sub-topics, the main topic of my research is the law of agricultural environmental protection. From the beginning of my university teaching years, in addition to the previous ones, I have been continuously researching agricultural law, land law, and cooperative law. My research activity includes the international relations of the mentioned legal areas, with particular regard to the Community law of the European Union, the legal material of individual European or non-European countries and the governing international trends. I deal with the foundations of constitutional law and civil law aspects of the researched areas, and at the same time I examine the regulatory content relevant to the main directions of my research in related areas of law, such as company law, company law, securities law, labour law, social law, real estate law, and the also related sources. My research also covered legal practice in the legal fields. In terms of the methodology of my research activity, it relies heavily on the legal history method, my analyzes also process the historical relationship of development in the given areas, but at the same time I also strongly apply the comparative method. During my research, I treat topics in an interdisciplinary manner.
