Analytical chemistry

Our research aims at the development and application of new, environmentally friendly, and reliable analytical techniques for environmental, food, biomass, forensic, and clinical analysis. For that, we utilize a wide range of instrumentation tools and technologies.
We strive to contribute to a safer and healthier world by promoting the Green Analytical Chemistry concept in our research.
We develop analysis techniques and procedures to decrease or eliminate solvents, reagents, and other materials that are dangerous to the individual or the ecosystem and provide rapid and energy-saving methodologies. For that, we apply statistical experimental design (DOE) to decrease the number of experiments during the process optimization stage and develop non-destructive cutting-edge analytical technologies, combined with chemometric tools (multidimensional data analysis and modeling), which are almost free of hazardous chemicals and wastes, fast and provide accurate, reliable and consistent results.

Biomedicine

Biomedicine lab investigates human pathogen Helicobacter pylori (HP) and its role in the development of liver diseases. HP is a Gram-negative bacterium living in the hostile environment of the human stomach. About 70% of the adult population in Estonia is infected with HP. The bacterium causes gastritis and peptic ulcers, and, in some cases, gastric cancer. HP can also affect other organs including the liver. However, the mechanisms by which HP causes liver damage and promotes carcinogenesis remain largely unknown. Ongoing research is expected to increase our understanding of the mechanisms behind bacteria-induced carcinogenesis.
Main research topics include:
- Role of Helicobacter pylori-induced invadosomes in liver damages. We have previously shown that infection with HP induces the formation of invadosomes in hepatocytes. We are currently investigating the mechanism behind this phenomenon using in vitro approach complemented with transcriptome sequencing.
- Clinical aspects of Helicobacter pylori-induced liver diseases. We are using the livers of mice infected with HP to analyse short- and long-term effects of the infection with focus on different markers such as YAP1 and CD44.
- Alteration of gut microbiota by Helicobacter pylori leading to the progression of liver diseases. For this study, we are collecting samples from Estonian patients. Our goal is to characterize Estonian HP strains, their effect on mouth/stomach/gut microbiota and liver.
- Effect of probiotic lactic acid bacteria on HP and HP-induced inflammatory response.

Brain bioelectrical signals research group

The research group is experienced in the interdisciplinary area of information technology and brain physiology. The studies are aimed to detect and interpret the features in the brain electroencephalography (EEG) signal characteristic for mental disorder (e.g. depression), occupational and/or environmental stressors comprising the advanced methods of signal analysis and the knowledge about brain neuronal activity. An original Spectral Asymmetry Index (SASI) has been developed and proved as a promising method in various applications.
Main results
- by applying EEG-based objective measures it is feasible to detect the changes and recovery caused by mRNA COVID-19 vaccine;
- there is no threshold for the biological or health effects of radio frequency radiation, while the health risk can be minimized by linking the health protection limit values to the level of radiation, in which no significant health effects have been noticed during a long period of exposure (6 V/m).

Centre for environmental sensing and intelligence

The Centre for Environmental Sensing and Intelligence is specialized in the development and deployment of rugged multi-modal sensors for measurements in extreme environments, data-driven modelling and eco- and ethohydraulics.
Core competences of the centre are:
- Underwater sensing in extreme environments including hydropower turbines, rivers, coastlines and glaciers.
- Real-time signal processing for rugged and reliable multi-modal autonomous sensors.
- Data-driven modeling and assimilation of outdoor sensor network data with numerical models.
- Eco- and ethohydraulic sensing and modelling, with a focus on fish and hydropower.
- Underwater multispectral cameras and automated vision methods for detection and tracking in adverse environments.
As our R&D activities are all related to monitoring human impacts (e.g. air quality in cities, negative effects of hydropower operations on river ecological systems and fish biodiversity), the methods and results we produce are highly relevant to the local, regional, national and transnational scales. For example, we are developing sensors to monitor human gaits to aid in rehabilitation which impacts the individual. At the same time, a modified version of this sensor platform is used by hydropower researchers to replace live fish in field studies, which impacts 100,000 of live fish throughout Europe.

DNA replication and genome stability

DNA replication remains one of the main targets of cancer therapies as cancer cells tend to proliferate faster and are generally prone to replication stress. However, most of the replication initiation research to date has been done using model organisms such as yeast Xenopus laevis egg extracts. The human DNA replication system is much more complex, and identifying human homologs using data from model systems has proven difficult, resulting in the need to re-evaluate every finding from a model system on a case-by-case basis.
The main goal of the group is to study the molecular mechanism of DNA replication initiation in human cells. Currently the research is focused on the following topics:
- The role of DNA polymerase epsilon in replication initiation in human cells;
- Developing a novel system to study DNA replication initiation in human cells based on proximity labelling;
- The role of Timeless protein in health and disease.
Key methods: mammalian cell culture, CRISPR/Cas9 based knock-ins, co-immunoprecipitations, immunofluorescent staining/microscopy, flow cytometry, molecular cloning, DNA fiber analysis, iPOND, proteomic screens.
