Jaclyn Johnson

Jaclyn Johnson is a Teaching Professor in the Department of Mechanical and Aerospace Engineering at Michigan Technological University. She leads research on diesel spray and combustion, optical diagnostics, and alternative fuel applications. Her work focuses on improving engine efficiency and emissions reduction through advanced diagnostics and modeling.

Education:

• PhD, Mechanical Engineering, Michigan Technological University
• MS, Mechanical Engineering-Engineering Mechanics, Michigan Technological University
• BA, Physics, Illinois Wesleyan University

Research interests include diesel spray characterization, spark ignition mechanisms, and thermophysical property modeling. She specializes in optical diagnostics (e.g., laser-induced incandescence) and computational fluid dynamics (CFD) for spray analysis. Her recent work explores fuel spray dynamics under engine-relevant conditions and biofuel applications in combustion systems.

Publications focus on diesel spray penetration, combustion vessel characterization, and alternative fuel integration. Her studies bridge experimental and numerical approaches to address challenges in internal combustion engine design.

No scientific awards are listed, but her contributions span over 15 peer-reviewed articles and book chapters. She has advised no named students but contributes extensively to graduate research through her teaching and lab work. Her research leverages the MAE department's combustion vessel laboratory for advanced optical measurements.
