Background
Dr. Erturk began at Georgia Tech in 2011 as an Assistant Professor, he was promoted to Associate Professor with tenure in 2016 (and Woodruff Faculty Fellow in 2017-2019), became a full Professor (and was named Woodruff Professor) in 2019, and was named Carl Ring Family Chair in 2022. Prior to joining Georgia Tech, he worked as a Research Scientist at Virginia Tech (2009-2011), where he received his Ph.D. in Engineering Mechanics in 2009. Dr. Erturk's research aims to understand, control, and leverage vibration and wave phenomena across geometric scales, disciplines, and applications. His sponsored research topics have covered a broad spectrum including energy harvesting from vibrating and other dynamical systems, leveraging nonlinear dynamics in smart structures, bio-inspired piezoelectric actuation/locomotion, mechanical and electromechanical metamaterials for elastic wave control and vibration attenuation, elastic/acoustic wave guiding using phononic crystals, wireless (ultrasonic) power and data transfer, understanding and exploiting vibration and wave phenomena in biomechanical systems (e.g. human skull-brain system), among other topics.
