Research & Expertise News at HSE University

The Linguistic Convergence Laboratory and the School of Linguistics at HSE University have created corpora of the Abkhaz-Adyghe languages spoken in the Western Caucasus. The corpora serve as valuable resources for studying these languages with their unique features and demonstrate the potential for their modern use. The corpora were developed through a series of field expeditions to the Caucasus conducted by HSE University researchers and students, combined with modern linguistic processing methods and collaboration with colleagues from regional universities. In this interview with the HSE News Service, Yury Lander, Leading Research Fellow at the Linguistic Convergence Laboratory and Associate Professor at the School of Linguistics, discusses the work of linguists.

Fuad Aleskerov, Tenured Professor and Director of the International Centre of Decision Choice and Analysis at HSE University, together with his colleagues, has developed methods of network analysis in bibliometrics that have made it possible to identify patterns in the appearance and citation of publications in academic journals, as well as their influence on each other. When one or a number of studies are frequently cited by a wide range of journals, this is an indicator that the research is of high quality. By contrast, extensive cross-citation within a limited group of journals increases the likelihood of identifying a network of predatory publications.

A team of Russian researchers, including scientists from HSE University–St Petersburg, has developed the first open multimodal dataset containing recordings of brain activity, heart function, and video observations to help researchers understand what happens in the human brain during deep concentration. In the future, the dataset could accelerate the development of neural interfaces, rehabilitation technologies, and AI systems. The article has been published in Scientific Data.

An international group of researchers, including mathematicians from the AI and Digital Science Institute at the HSE Faculty of Computer Science, has provided a theoretical justification for a simple and computationally efficient method of estimating uncertainty in Stochastic Gradient Descent (SGD). The paper has been published on the scientific preprint server arXiv.org and presented at AISTATS 2026.

At the UN Trade and Development (UNCTAD) headquarters in Geneva, experts and representatives of competition authorities and international organisations discussed competition in the global grain trade. The discussions resulted in the establishment of a BRICS project task force that will prepare the bloc’s first joint sectoral study of the grain market. The initiative was presented by the BRICS Competition Law and Policy Centre based at HSE University.

In corporations, sports, and academia, people often face challenges they cannot handle alone. In such cases, selecting the right team is crucial. Tatiana Mayskaya, Associate Professor at the HSE Faculty of Economic Sciences and the International College of Economics and Finance, together with colleagues from foreign universities, examined team characteristics and found that less diverse teams are better suited to objectives where a high average performance is important, whereas more diverse teams are preferable when avoiding failure is critical. The paper has been published in Economic Theory.

The devices, created by student teams, will conduct space research on the properties of promising solar cells, on-board energy storage systems, and serial electronics for student satellites.

Economists at HSE University have examined how smokers respond to changes in cigarette prices. When tobacco prices increase, cigarette consumption does not always decline. In fact, spending on tobacco may even rise: according to the researchers, a 1% decrease in cigarette affordability leads to a 0.28% increase in per capita tobacco expenditure. The findings suggest that to reduce smoking rates, tobacco prices must rise faster than household incomes. The study has been published in Voprosy Statistiki.
