HUN-REN-ELTE Research Groups
Until 2019, as part of its public duties, the Hungarian Academy of Sciences (MTA) maintained scientific research groups at higher education institutions through agreements with these institutions. Since the establishment of the Eötvös Loránd Research Network (ELKH), newly formed research groups have operated under its auspices with central funding. As of September 1, 2023, ELKH continues to operate under the name Hungarian Research Network (HUN-REN), reflecting its English designation.

The research focuses on a branch of combinatorial optimization most prominently represented by Alexander Schrijver’s seminal three-volume work Combinatorial Optimization (2003). The core idea is that the development of polynomial-time algorithms for solving specific problems relies on a deep structural understanding of those problems. The primary aim of the group is the algorithmic analysis of optimization problems on graphs and networks, with special emphasis on exploring the boundary between polynomially solvable cases and NP-complete problems. Essential tools for this work include the theory of matroids and submodular functions, as well as polyhedral combinatorics. A particularly significant area of interest involves problems where parity plays a central role—such as matchings, path packings, T-joins in graphs, and the matroid parity problem.

The research group, through studying dog-human interactions, has discovered how to design and develop social robots that can cooperate effectively with humans. The numerous behavioral similarities between dogs and humans are the result of a convergent evolutionary process in which dogs have adapted to the human environment. These functional similarities are evident not only in the main dimensions of the behavioral repertoire of both species but also at the level of components known as social primitives. Moreover, the dog is a promising model species for studying the evolution of human social cognition. The research is carried out in broad national and international collaboration, aiming to establish the foundations of a natural animal model that can significantly contribute to evolutionary modeling of humans and potentially offer new directions for robotics research.

HUN-REN–MTM–ELTE Paleontology Research Group

The Paleontology Research Group contributes to the understanding of the evolutionary history of the biosphere through high-quality paleontological research and internationally impactful publications. Their research is organized around three main themes: 1.) Based on fossil records, they study major events in the history of the biosphere that involved significant changes in biodiversity, such as extinction events and shifts in fauna and flora, both in deep geological time and in the Quaternary period leading into human history. 2.) Using a systems approach and incorporating geochemical analyses, they examine the relationship of these events to simultaneous global and regional paleogeographic and environmental changes, with a particular focus on climate change. 3.) Their research relies on detailed taxonomic work and the study of Hungary’s and the surrounding region’s significant fossil sites. Within the examined fossil groups, they conduct both monographic descriptive studies and paleobiological research.

 

HUN-REN–ELTE Protein Modeling Research Group

Head of the research group: András Perczel, Academician, Professor
Institute of Chemistry, Department of Organic Chemistry, Faculty of Science, Eötvös Loránd University (ELTE)
E-mail: perczel@chem.elte.hu
Phone: +36-1-372-2500/1653

The research group focuses on protein studies. Most proteins in the human body participate in physiological processes by associating with other proteins, forming complexes that create stable molecular structures and functional organization. These protein complexes are formed through self-assembling or assisted processes, during which surfaces that are complementary in shape and electrostatic pattern align with each other. In order to interpret, regulate, or exploit such processes, it is essential to precisely understand the structural and compositional properties of protein surfaces capable of association, as well as the factors and mechanisms that drive this association. The research group aims to conduct detailed investigations into these questions, focusing on protein systems that are also of medical relevance.

HUN-REN–ELTE Numerical Analysis and Large Networks Research Group

Head of the research group: Péter Simon, Professor
Institute of Mathematics, Department of Applied Analysis and Computational Mathematics, Faculty of Science, Eötvös Loránd University (ELTE)

E-mail: peter.sziklai@ttk.elte.hu

The primary objective of the research group is to conduct fundamental research in the field of geometric and algebraic combinatorics—particularly focusing on problems originating from finite geometry that can be approached using its toolkit or other algebraic methods. Special emphasis is placed on extremal combinatorial and graph-theoretical problems, stability questions, qq-analogs, colorings, the direction problem, combinatorially defined structures in finite planes (e.g., blocking sets), the polynomial method, and non-Desarguesian planes. Their research so far has covered topics such as the excluded subposet problem, search problems, projective and affine blocking sets, full automorphisms of affine planes, 3-nets embedded in group-coordinatizable planes, pseudorandom sequences, and certain graph coloring problems. Additionally, their goals include the study of projective and affine blocking sets, extremal combinatorial structures (especially intersecting set systems), the stability of special point sets in PG(2, q), classical and generalized direction problems, bisecants of large Rédei-type blocking sets, semiovals, 1-intersecting graphs, Ramsey-type problems, dominating sets in the incidence graphs of projective planes, algebraic-geometric error-correcting codes, and finite Bol quasigroups.

The complement system plays a crucial role in protecting the body against infections and in regulating immune processes. However, its malfunction can lead to damage of the body’s own tissues and contribute to the development of serious diseases. The research aims to uncover the physiological functions of complement proteins and their roles in disease mechanisms. These insights may support the development of novel preventive and therapeutic strategies. Another key objective of the group is the development of new complement inhibitors based on Factor H and FHR proteins for therapeutic applications.

The predecessor of the research group was established at ELTE in 2013 with support from the National Brain Research Program (NAP). Their work is currently supported by several major grants, all aimed at understanding the normal and pathological functioning of the nervous system. Their main research focus is on the brain mechanisms underlying the parent–child bond, and more broadly on social neurobiology. Within this framework, their goal is to identify the neuronal networks responsible for social behavior and to clarify the roles of the participating neurons. The research employs modern chemogenetic tools, neuron-specific tract-tracing methods, high-throughput behavioral testing, as well as genomic and proteomic approaches to understand molecular-level changes in the brain. This line of research is complemented by studies on the mechanisms of neurological disorders affecting social relationships. Their aim is to uncover the network-level and molecular underpinnings of conditions such as depression, autism, epilepsy, Alzheimer’s disease, stroke, and mitochondrial disorders.

Our research primarily focuses on investigating the role of innate immune components in supporting and regulating adaptive immunity. Particular attention is given to the complement system, which serves as a critical link between these two branches of the immune response. We study how the complement system regulates the functions of dendritic cells, macrophages, T and B lymphocytes—especially the role of the complement protein C3, its various activation fragments, and their corresponding receptors. Our research also extends to exploring how different cellular and molecular mechanisms contribute to the pathogenesis of autoimmune diseases, particularly rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Furthermore, we examine how B-cell-targeted therapies—especially anti-CD20 antibody treatment—affect the function of B cells that survive the treatment.

The MTA-ELTE-MTM Ecological Research Group is a research unit of the Hungarian Academy of Sciences, hosted by Eötvös Loránd University and the Hungarian Natural History Museum. The group consists partly of members of the former MTA-MTM Animal Ecology Research Group, and partly of researchers who joined during or after the new funding period that began in 2012. Some members are at the beginning of their scientific careers, working on their PhD theses or having recently defended them, while others already hold a Doctor of Science (DSc) degree or the title of private professor (habilitated university lecturer). The head of the group is academician János Podani. The group’s research focuses on the ecological relationships of plants, animals, and pathogens. Their theoretical, methodological, and experimental work is published in leading international journals in the field of ecology and related disciplines such as conservation biology, agroecology, behavioral ecology, taxonomy, and epidemiology. Members of the group are actively involved in undergraduate and doctoral education at various universities as guest lecturers or supervisors, and they also participate in science communication and nature conservation activities.

E-mail: tel@general.elte.hu
Phone: +36-1-372-2500/6124

Since 2012, the group’s research has focused on field theory, particle physics, as well as statistical and environmental physics. The five-year research plan is centered around two main areas: quantum field theory and statistical physics. In recent years, a third major research direction has emerged, namely “environmental and climate-motivated physics.” The group conducts basic research, whose societal relevance lies in advancing our understanding of the world and the behavior of physical systems. Its economic utility is often indirect or becomes apparent only after a longer period of time. The research group collaborates with several domestic institutions (e.g., the Institute of Nuclear Techniques at BME, the Department of Theoretical Physics at the Centre for Energy Research). They are also involved in education at ELTE, teaching various theoretical physics courses, and maintain extensive international collaborations (e.g., Ben-Gurion University of the Negev in Israel, Aix-Marseille University, University College London, CERN and the University of Geneva, Freie Universität Berlin, the universities of Oldenburg, Cottbus, and Hamburg, and the Max Planck Institute in Dresden).

The main goal of the research program is to preserve the legacy of Tamás Varga and to integrate three decades of subsequent development into it. Particular emphasis is placed on incorporating advances and findings from cognitive sciences, recognizing the growing role of information technology and modern tools, and extending Tamás Varga’s methods to secondary education—an effort that, despite some valuable attempts, remained incomplete. During the implementation of the project, educational support materials will be developed based on these guiding principles, tested in teaching practice, and—once evaluated and, if necessary, revised—made freely available online for all Hungarian mathematics teachers. A teacher training program is also being prepared to familiarize educators with the group’s work and principles, enabling them to engage in interactive learning which they can then pass on to their students. In addition, the group aims to restore the international reputation of Hungarian mathematics didactics. In the first year, methodological research is being conducted to lay the groundwork for future activities, organized across nine research subgroups.
