- Mathematical analysis
- Algebra
- Pure mathematics

His primary areas of investigation include Pure mathematics, Algebra, Discrete mathematics, Operator theory and Hilbert series and Hilbert polynomial. His Pure mathematics research includes themes of Ball and Bergman space. His Algebra study combines topics from a wide range of disciplines, such as Class, Algebra over a field and Complex geometry.

His Discrete mathematics research incorporates themes from Compact operator on Hilbert space, Invariant subspace, Bounded function, Space and Germ. His work carried out in the field of Compact operator on Hilbert space brings together such families of science as Nuclear operator and Finite-rank operator. His Operator theory research is multidisciplinary, incorporating elements of Banach *-algebra, Linear subspace, Hardy space, Reflexive operator algebra and Approximation property.

Ronald G. Douglas spends much of his time researching Pure mathematics, Bergman space, Quotient module, Discrete mathematics and Combinatorics. His Pure mathematics research is multidisciplinary, incorporating elements of Ball and Contraction. The study incorporates disciplines such as Polynomial and Principal ideal in addition to Quotient module.

His Discrete mathematics research is multidisciplinary, incorporating perspectives in Tuple, Invertible matrix and Hermitian matrix. In his study, Hilbert space is inextricably linked to Multiplier, which falls within the broad field of Combinatorics. As part of one scientific family, Ronald G. Douglas deals mainly with the area of Hilbert space, narrowing it down to issues related to the Complex geometry, and often Holomorphic function and Operator theory.
