Our research group aims at providing fundamental insights on the role of turbulence in basic and applied problems of high interest, which can be divided in the following sub-areas:

i) structure of the boundary layer over complex topographies;

ii) wind & hydrokinetic energy technologies,

iii) scalar transport over urban and natural environments,

iv) flow-structure interaction; and

v) instrumentation for turbulence measurements.

We have developed a comprehensive research on these topics that are going to be sustained and expanded in the future. Our versatile experimental approach combines a set of state-of-the-art experimental techniques, including particle image velocimetry (PIV), computer vision, and our recently developed 3D particle tracking velocimetry (PTV). This framework allows us to study fluid dynamics from Eulerian and Lagrangian frame of references
