Csaba Mezei

General Secretary

With a background in education I spent my entire professional career in the green non-profit sector. Throughout that 17 years my positions varied from activism to executive assignments. In 2001 I was part of the founders’ team of Greenpeace in Hungary. Until 2009 I was involved in many environmental campaigns (e.g.: GMO-free Hungary, Zengő, Rába campaign, Energy (r)evolution, etc.) as contributor, manager and leader. In 2006 I became the country office director of the organisation. 

Between 2009 and 2018 I worked at the Regional Environmental Center (REC) as a project manager and expert being responsible for EU funded research and development projects on various topics such as environmental information, smart cities and mobility. Besides I learnt a lot about fundraising and business development in the European research area. 

In my new position as general secretary of CEEweb I look for new challenges, learning opportunities and the chance to further work on making a better world through protecting the environment and contribution to a more sustainable ecosystem.

Klára Hajdu

Senior Policy Officer


With the professional background of being a biologist I joined CEEweb in 2000 still as an intern. I started to work on global and regional biodiversity policies, and later shifted focus to EU policy development and implementation. I was also intensely involved in the proactive policy forming of CEEweb in relation to biodiversity and sustainability, as my primary interest lies in finding holistic and effective responses to seemingly unrelated problems.

Currently I focus on sustainability issues related to resource use and the EU budget. This includes policy and campaigning work on EU level with the main aim to sustainability proof the future EU budget, which can help the European transition towards sustainability and reviving the European project for the benefif of the people and the planet.

Gabriella Nagy

Project Coordinator

I graduated in Landscape Architecture in 2001. For 10 years after that I ran my own private firm on small and medium scale Greenfield designing. In 2010 I graduated in Environmental Protection, and then did a specialization in Forest Pedagogy (2012).

Afterwards, I got a scholarship to pursue PhD studies at University of West-Hungary, in the Doctoral Program of Forest Value Assessment. My PhD thesis focused on development of community spaces in forests and their impact on quality of life. The aim was to examine and develop tools, which can be used in the decision-making process of the complex strategic development of green fields. At the end of my doctoral studies I taught for four years university courses on environmental economics, landscape design and rural development.

Thor Morante Brigneti

Communications and Project Coordinator

I hold an MSc in Environmental Sciences, Policy and Management from Lund University (Sweden) and a BA in Literature from the National University of San Marcos (Peru), and I have been working in the communications, project management and international cooperation fields for the past 10 years. I started my career as a politics and environmental journalist in Peru, reporting on issues ranging from rural sustainable development in the Andes to the depredation of the Amazon due to illegal gold mining. In Central and Eastern Europe, I have worked managing a knowledge-sharing platform on Low Emission Development Strategies, as well as having been occupied on policy research on multilevel governance models and on communications tasks for the implementation of a diversity of projects.

Now, at CEEweb for Biodiversity, I am coordinating the INSiGHTS project and the communications activities of the organization.

Linda Szabó

Communications and Creative Assistant

I followed film and media studies at the University of Pécs and also studied photography and graphic design. I gathered experience as project coordinator, filmmaker, graphic designer, photographer at different non profit and for profit organisations after my graduation.

I have been working with CEEweb since 2016 as a creative assistant, where I develop communication materials, including videos, brochures and publications to raise awareness about the importance and beauty of nature.

I’m grateful for every moments spent in nature and if I can help to take care of it via my work.

Vivien Vati

Project and Communications Assistant / Internship coordinator


I graduated as an architect and after my studies I worked in small communities and NGOs, mostly related to the sustainability field. I have dealt with renovation of old buildings, teaching solutions for sustainable architecture, and ecological farming.

I am strongly interested in the environmental sciences field, protecting our natural resources and raising interest in eco-conciousness. At CEEweb I am working within a project looking forward to find solutions for slow, green and healthy tourism strategies, which could make the regions more attractive while also protecting their natural and cultural resources.

Gábor Szilágyi

Financial Manager


I graduated as a economist at the University of Economics, in Budapest, and backed those studies with further courses, such as on certified accounting. Along the years, I have worked for both profit and non-profit oriented companies and foundations, such as  the Hungarian Telecommunications Company and Hungarian Radio, among others.

At CEEweb, I deal with the financial related tasks, both at the institutional and at the project levels.

Viktória Selmeczy

Office Manager

Viki kép

I graduated at the University of Pécs on HR studies in 2009. For 9 years, I worked in diverse support and administrative roles in all kinds of  companies (big and small, local and multinational).

Both in my private life and in my work I am committed to sustainability and I spend most of my time dealing with activities related to environmental protection.  I am tirelessly developing my household for it to become a zero-waste home, while also working for my workplace to be as eco-friendly as possible. Beyond the office, I have always been fascinated about nature and enthusiastic on working for it.

Now, as CEEweb’s Office Manager, I feel that I can finally do even more to preserve our environment.

I believe that sustainable living is a kind of high level “richness.” When someone can afford to not only think about her or himself, but can moreover take care of underprivileged people, the environment and the planet, that is the real richness.

Furthermore, I am responsible for delivering national and international projects related to the Convention on Biological Diversity (CBD) policies and related to Pan-European Biological and Landscape Diversity Strategy (PEBLDS), the implementation arm of CBD, including project design and implementation.
