I'm a theoretical physicist and assistant professor at Decision Analysis and Support Unit at SGH Warsaw School of Economics . I am working on new quantum machine learning algorithms for prediction and forecasting and applications of quantum technology. Much of my effort focuses on quantum time series analysis. The modeling of time series has received very little attention from the quantum community to date; hence, much of the work in this area is without any prior research. One of the most promising and challenging area of time series analysis is quantum time series anomaly detection, which I actively collaborate on with Prof. Jacob Cybulski, Melbourn, Australia. Quantum machine learning techniques can assist in discovering complex patterns that deviate from the typical time series characteristics. I also work as an MLops. I develop Python tools for data scientists and integrate quantum and classical optimization techniques to enhance business processes.
