Research Interests

Research: Multifunctional (photonic and phononic) structures, Laser based ultrasonic sensors, Interfacial properties of thin film materials, and Phonon transport in electromechanical structures

My research group is focused on the design of novel multifunctional materials and structures that enable control of elastic/acoustic and electromagnetic waves in materials. In particular, we are interested in basic research, to understand the physics of wave propagation in 2D and 3D nano and microscale periodic materials, and to develop novel experimental tools with high spatial and temporal resolution for visualization and measurement of acoustic phonon and plasmonic wave propagation in materials. We hope to leverage basic research in these areas to realize new engineering approaches, to sound/heat insulation, multifunctional sensors, actuators, and elastic/acoustic and super-resolution imaging. My group is also interested in applications of laser material interaction, to studying the dynamic interfacial properties of soft and hard thin films, nondestructive defect metrology in additive manufacturing, and mechanical characterization using laser generated elastic stress waves.

In the Classroom

Prof. Balogun teaches undergraduate level courses EA-206-2: Engineering Analysis: Statics and Dynamics, and ME 363: Mechanical Engineering. EA-206-2 provides freshman level undergraduates with a solid background in the application of Newton’s laws to engineering problem solving. ME 363 provides students with a strong  background in modeling and interpretation of oscillatory motion in mechanical systems, based on physics based analysis approaches.

Prof. Balogun also teaches a graduate level course, ME 495: Dynamic deformation of materials. The course focuses on  aspects of wave motion in solids including, linear and nonlinear elastic deformation, fracture, and diffraction, induced by dynamic mechanical loading. Specific examples from metals, polymers and composites are provided. The course also surveys available experimental techniques for understanding dynamic deformation in materials.
