Broadly, my research interests centre around building and evaluating uncertainty-aware (also known as *probabilistic*) models for decision making that learn from data. Thus Statistics, Machine Learning, and Probabilistic modelling are the fields that I naturally find myself working in. These days, I mostly focus on uncertainty modelling in machine learning, especially Deep Learning. Making machine learning models output probability distributions that capture the uncertainty of predictions and developing coherent calibration evaluation methodology for probabilistic models are my main current research undertakings. However, the largest part of my research so far has dealt with learning and decision strategies under uncertainty in probabilistic temporal models. In more detail, I have engaged in the study of

- sequential testing/estimation and quickest change-point detection problems in Bayesian Statistics,
- trading strategies and valuation of financial derivatives in Financial Mathematics,
- stochastic differential equations and stochastic filtering techniques.
