Hirotaka Sakaue

Hirotaka Sakaue serves as an Associate Professor in the Department of Aerospace and Mechanical Engineering at the University of Notre Dame, where he also holds the position of Director of Inclusive Excellence and Engagement. His interdisciplinary research program integrates fluid mechanics and chemistry to develop novel sensing and flow control technologies for aerospace and environmental applications.

His academic credentials include:

• Ph.D. in Philosophy (Aeronautics and Astronautics), Purdue University, 2003
• M.S. in Engineering, Purdue University, 1999
• B.S. in Bioscience and Biotechnology, Tokyo Institute of Technology, 1996

Prof. Sakaue's primary research areas are luminescent imaging and chemical flow control. In luminescent imaging, he develops nano-structured sensors that provide time-resolved, spatially resolved measurements of chemical species (e.g., oxygen, hydrogen, CO2) and physical parameters (pressure, temperature). His chemical flow control research focuses on using functional chemicals and micro-structured surfaces (such as superhydrophobic coatings) to manipulate fluid flows and prevent ice accumulation on critical surfaces like aircraft wings. These efforts contribute to advancements in energy efficiency, environmental sustainability, and aerospace safety.

Analysis of his recent publications (2019-2020) reveals a concentrated effort in experimental techniques for flow control and measurement. Key themes include the application of microfiber coatings for drag reduction, superhydrophobic surfaces for ice prevention, and luminescent methods for hypersonic flow diagnostics. His work consistently bridges fundamental fluid dynamics with practical engineering solutions, particularly in the aerospace domain.

Details regarding Prof. Sakaue's graduate student advising and external grant funding sources were not included in the source material. However, his active laboratory and collaborative research projects suggest ongoing engagement in both areas.

The Sakaue Laboratory at Notre Dame provides specialized facilities for developing and characterizing chemical sensors and coatings. The lab's research follows a structured three-step process: (1) development of novel chemical sensors/coatings, (2) rigorous characterization of these materials, and (3) application to solve complex fluid science problems. Current projects span four signature areas: Flow Measurement, Chemical Flow Control, Bio/Biomedical applications, and Green Energy/Environment, often in partnership with external organizations.
