Chang-Hwan Choi

Chang-Hwan Choi is an American and South Korean engineer and professor specializing in nanofabrication, micro‐ and Nanofluidics, and surface engineering. He is currently a professor in the Department of Mechanical Engineering at Stevens Institute of Technology in Hoboken, New Jersey. His research focuses on developing micro/nanomanufacturing techniques and multifunctional surface technologies for applications in fluid mechanics, additive manufacturing, corrosion protection, and biomaterials.

Early life and education

Choi completed his early studies in South Korea, earning his Bachelor of Science and a Master of Science degree in Aerospace Engineering from Seoul National University. He later pursued graduate studies in the United States, obtaining a second Master’s degree in Engineering, with a focus on fluid, thermal, and chemical processes, from Brown University, followed by a PhD in Mechanical Engineering from the University of California, Los Angeles (UCLA) in 2006.

Research and contributions

• Nanofabrication and Surface Engineering: Development of scalable techniques for creating well-ordered, large-area nanostructured surfaces that reduce friction, enhance corrosion resistance, and impart antimicrobial properties.
• Micro/Nanofluidics: Investigation of fluid dynamics at the micro- and nanoscale with applications ranging from energy harvesting (e.g., streaming current in nanofluidic channels) to drag reduction and anti-icing surfaces.
• Additive Manufacturing: Exploration of 3D metal printing processes, including the development of new metal alloys and surface modifications to improve anti-corrosive properties.
