I'm a theoretical physicist and an assistant professor at the Decision Analysis and Support Unit at SGH Warsaw School of Economics (Poland). I am a dedicated researcher who powerfully explores the convergence of cutting-edge technologies and practical business applications. My primary research interests lie at the intersection of Quantum Machine Learning and Quantum Computing on NISQ (Noisy Intermediate-Scale Quantum) devices, where I aim to unlock quantum computing’s potential in addressing complex problems. Additionally, I am deeply immersed in streaming data analytics, where I endeavor to leverage real-time data for valuable insights. A significant aspect of my work involves integrating quantum and classical optimization techniques to optimize business processes.
I have made notable contributions to academia through publications showcasing my expertise in outlier detection. I have ventured into challenging domains such as complex networks and time series data, developing innovative methodologies for outlier identification. These contributions have led to a deeper understanding of intricate data structures.
My research exemplifies a dedication to pushing technological boundaries while tackling real-world challenges and driving advancements in quantum computing and data analytics.
