Research Interests:
Professor Ballarini's research focuses on the development and application of theoretical and experimental techniques to characterize the response of materials to mechanical, thermal, and environmental loads. He is particularly interested in formulating analytical and numerical models for characterizing fatigue and fracture of materials and structures.
