My research focuses on adaptation in populations that are severely challenged either by environmental change (natural populations) or by exposure to drug treatment (pathogen populations). I hope that insights from my research can contribute to improving conservation efforts and assist in decelerating the emergence of drug resistance. As a mathematician, I am mainly interested in stochastic modeling (in particular in the application of branching process theory to problems in biology).

Evolution, Antibiotics, and Us by H. Uecker, H. Sachdeva, K. Hudáková (pdf).
Abstract: Antibiotics are an integral part of modern medicine, so widely used that healthcare without them has become inconceivable. But have you ever wondered what antibiotics look like from the perspective of bacteria? How antibiotic treatment changes their environment? How bacteria adapt to this dramatic change? And what happens to the "good" bacteria in our body during treatment? In this issue, we will make an excursion into the fascinating world of bacteria and take a closer look at the evolution of antibiotic resistance.
A glimpse into the world of human viruses by H. Uecker and B. Trubenová (pdf).
Abstract: Viruses are tiny biological agents that possess a genome but cannot replicate on their own. In order to replicate, they need to infect host cells and hijack the host's machinery. Therefore, one can argue that they are not really living organisms. Alive or not, viruses are very successful at tricking and hijacking cells. There are an estimated 1031 viruses on this planet, which infect all forms of life. They play an important role in many ecosystems and shape life on earth. In this issue, we will have a look at viruses that infect humans. But don't forget -- no form of life is safe.
Viruses in the world of bacteria by H. Uecker and B. Trubenová (pdf).
Abstract: When you think of viruses, you probably think of diseases that affect you and other people: influenza, measles, rubella and many more. However, humans are not the only victims of viruses. In fact, the first virus ever discovered did not cause a disease in humans but in tobacco plants. Today, we know that viruses are ubiquitous and infect all formsof life -- humans, birds, plants, insects, etc. There is no living species that is not affected by viruses; not even bacteria are safe from them! Some viruses kill bacteria, others bring benefits to their bacterial hosts. Let’s take a closer look at this minia-ture world of attack and defense!
