2018 - 2022, APVV-17-0141 Analysis of Barriers in Access to Employment for Marginalized Groups of Population: Selected regions of Slovakia in socio-economic, geographic and socio-anthropological perspective (Slovak Research and Development Agency) - co-researcher. The main objective of the research project is to define causality between spatial localisation of Roma settlements, including physical infrastructure conditions and spatial localisation of employment opportunities. The specific objective of the project is to identify: (i) living conditions including qualification profile of this segment of population, in selected three territories in marginalized regions of Slovakia and (ii) the localisation and structure of disposable employment opportunities in the same selected territories. Recommendations aimed at improvement of the access of marginalized groups to the labor market in these disadvantaged territories will be a part of the outputs of the project.

2021 - 2023, 047UK-4/2021 / Spatial Inequalities and Disadvantages in Human Geography Education: Innovative Geoinformatics (Cultural and Educational Grant Agency of the Ministry of Education, Science, Research and Sport of the Slovak Rep.) - main researcher. This project deals with participatory higher eduaction formats designed for geographic programs. Standard course packages disaggregate the social reality and its contexts into a series of narrowly defined, mutually almost unrelated partial perspectives. As a result, the final product of education contains highly limited abilities of critical approach towards a relevant problem, the subject of study in current society generally at a high level of complexity, crucially of extraordinary dynamism, and also interpretive pluralism. Lack of skills to deal with real world research proves to be critical during experiments with team collaboration on numerous student projects, in contact with external environment of non-geographic disciplines, prospective employers for graduates, or research projects to which students contribute during studies accorsing to years of experience. Objectives of this project include audit of participatory formats of education, collection of multilayer feedback, redesign of relevant courses, and finally teacher trainings in soft skills. As the main result, participatory education processes are expected to become fully professionalized, shifted to a significantly higher qualitative level corresponding to the current and projected future requirements concerning graduates' skills and abilities in knowledge creation.

2017 - 2019, 1/0246/17 When work is not sufficient: multiple marginality in Slovak society - labour-market related social and spatial disadvantage (Scientific Grant Agency of the Ministry of Education, Science, Research and Sport of the Slovak Rep.) - main researcher. The project was focused on the identification of processes in Slovak society that have long led to the marginalization of part of society in connection with low-paid jobs. The project focused on field research in some of the affected rural communities.

2015 - 2018, Strategic Grant Project No. 31510026 Transport Integration for Prosperity. The Importance of Rail Connections for the Internal Cohesion of Visegrad Countries (Visegrad Fund - Stragegic Grant) - co-researcher. The objective of the project was a comparison of transport policies of V4 member countries in the segment of public railway transport on the level of international long-distance, regional, and local cross-border connection, for which both qualitative and quantitative approaches were be used. The comparison was based on political-economic and transport-geographical analysis of the present situation, and on the identification of capacities and risks of possible future development. The project attempted to define variations of possible measures which will lead to harmonization of individual V4 countries’ approaches in such a way as to support the cohesion of cross-border regions as much as possible.

2013 - 2016, APVV VV-0018-12 Human-geographic and demographic interactions, nodes and contradictions in spatio-temporal network (Slovak Research and Development Agency) - co-researcher. The project was focused on modeling of some humangeographical and demographic phenomena in time and space, i.e. a standard geographical space-time network, in which the existence of interactions, nodes but also certain contradictions is assumed.
