Dr. Do's research interests lie in software engineering, particularly software testing, maintenance, and empirical methodologies. She has been working on problems on evolution-aware testing techniques for object-oriented systems, including test selection, prioritization, test suite design, and unit/integration testing.
Her current research is focused on 1) creating cost-effective regression testing techniques that address the testing process and domain contexts, 2) creating regression testing strategies that address system lifetimes, 3) creating economic models that enable the adequate assessment of techniques and strategies, 4) empirical methodologies to evaluate cost-benefits related to testing techniques considering various factors such as testing context and a system's lifetime, and 5) empirical evaluation which involves various research questions on software testing techniques and problems.
