Research Interests

Research: My main interests lie in the areas of analysis and dynamical systems. In particular, I am interested in the local dynamics of holomorphic systems.

Research with graduate students: I welcome inquiries about research opportunities in areas close to my interests from motivated graduate students in our program.

Research with undergraduate students: I am interested in guiding research projects that explore topics beyond the curriculum, or investigate applications of concepts studied in courses such as differential equations or complex analysis. In some cases, we will work on an actual problem (or a special case that is more accessible); in others, we will learn about the background and the reasons why a problem is interesting.
