Research Interests

Research: Optical and acoustic wave Sensing, Biomechancs of Soft Materials, Phononic Structures, Thermal Transport

My research group studies the propagation of coherent and incoherent elastic vibrations in materials, to understand how these carriers impact energy transport in bulk materials and across interfaces in condensed matter, and to elucidate the structure-property relationships of materials. We utilize optical and scanning probe techniques to image and characterize the thermal conductivity of bulk and low-dimensional electronic materials, and the thermal boundary resistance of interfaces in thermoelectric materials, vibrational properties of condensed matter, viscoelastic properties of biofilms and biological tissues, elastic properties of thin films and interfaces, and to study the coupling of optical and acoustic oscillations in nanostructures. We also rely on continuum modeling to understand the sensor and material physics.

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.
