Christopher Felder works in mathematical analysis, focusing on operator theory and function theory in spaces of analytic functions such as Hardy spaces. A recurring theme is the study of optimal polynomial approximants, which are tools for approximating functions using polynomials, along with related questions about zeros, interpolation, and geometry of function spaces. Some of his work also applies mathematical methods to financial problems like stock return prediction and trading strategies.
