Post PhD Position:

July 26th, 2022- Present: Research staff member in the Mathematical Modelling and Intelligent Systems for Health and Environment (MISHE), Atlantic Technological University Sligo with Dr Marion McAfee. 

Research Theme: 

My research explores how complex systems behave over time when randomness, interaction, learning, and control intersect. I am especially interested in ergodicity—the idea that a system’s long-run behavior becomes independent of its initial state—and how this principle can fail, emerge, or be shaped through control and learning. 

All my research papers can be found in Google Scholar, ResearchGate, ORCID ID, Scopus ID, and here is my LinkedIn profile link.
