Research team

Laboratory head

• Josué Labaki, PhD. I graduated in mechanical engineering from the São Paulo State University at Ilha Solteira-SP, then went on to obtain my MSc and PhD from the University of Campinas (Unicamp), with a four-year post-doc at Simon Fraser University - Canada, and Unicamp. I'm currently an assistant professor at the School of Mechanical Engineering/Unicamp.

Post-doctoral fellow

• Ignácio da Silva, PhD is bringing to our lab his experience with nonlinear vibration absorbers to characterize and design energy harvesting in vibratory systems.

PhD candidates

• Amanda Oliveira, MSc is the only civil engineer in our laboratory. In her Master's program, she derived a model of piled structures exchanging energy through the soil. In her PhD, she is deriving novel models of pile group vibration.

• Aldemar Siqueira, MSc develops methods to study topology optimization of buried structures such as foundations for surface structures and reinforcements for canals and tunnels.

MSc candidates

• Bruno Benegra will study topology optimization of seismic metamaterials to design ground vibration attenuation devices.

• Lucas Mamedes is studying topology optimization of 3D dynamic soil-structure interaction problems.

• Leonardo Antoniazzi is studying how gabion and concrete mats can be used to attenuate ground vibration.

• Cassiano Bueno is a mechanical engineer from the Brazilian Synchrotron Light Source. He investigates how deep learning strategies can help us make sense of seismic signals with poor signal-to-noise ratios.

• David Carneiro, MSc* used coupled boundary- and finite-element methods to understand how a heavy mass such as a long wall on the surface of the soil alters the vibration profile of its surroundings. 

• Iago Cavalcante, MSc* derived advanced numerical integration schemes to deal with singular, transcendental integrands. 

• Ana Carolina Vasconcelos, MSc* crafted an efficient implementation of the impedance-matrix method for massively large pile groups. 

• Emanuel Tavares, MSc* investigated how the flexibility of the foundation affects the topology optimization of piled structures.
