The main focus of my research is experimental particle physics within the energy-frontier ATLAS detector and the intensity-frontier Belle II detector.


At ATLAS I am involved in searches for new long-lived particles that are predicted in a variety of scenarios of physics beyond the standard model. Having no background, the sensitivity of such searches will grow linearly as ATLAS collects more data. At the same time, we are expanding the search to new signatures motivated by new models. 


My current Belle II focus is decays of B mesons involving tau leptons. Measurements of these processes are in tension with the standard-model predictions, possibly indicating the presence of new interactions and motivating more precise measurements. For this purpose, we are employing new techniques that utilize the high spatial resolution of the detector.


In addition, I am involved in phenomenology research in collaboration with theorists.
