DESCRIPTION:Prof. Matteo Pezzulla\, Department of Mechanical and Product
 ion Engineering\, Aarhus University\nAbstract: The efficient redistribut
 ion and control of flow is essential in many biological and engineered sys
 tems\, from the cardiovascular network to plants and soft robotic devices.
  A recurring strategy in Nature is the use of fluid–induced elastic defo
 rmations to passively regulate transport. In this talk\, I will focus on f
 luid-induced elastic instabilities in soft hydraulic systems and their exp
 loitation for passive flow control. I will present two prototype valves: o
 ne based on flow-driven buckling of slender beams and another exploiting s
 napping instabilities in thin spherical shells\, where the instability is 
 harnessed to achieve passive control. Using a combination of controlled de
 sktop-scale experiments\, numerical simulations\, and theoretical modeling
 \, I will rationalize the underlying instability mechanisms and derive des
 ign rules based on scaling relationships among material\, geometric\, and 
 fluid parameters.\n\nBiography: Matteo works as an Associate Professor i
 n the Department of Mechanical Engineering at Aarhus University\, Denmark.
  His research explores soft hydraulics\, with a focus on understanding flu
 id-induced elastic instabilities in natural and engineered systems. His wo
 rk combines theoretical\, numerical\, and experimental approaches\, drawin
 g from continuum mechanics and differential geometry. Previously\, Matteo 
 investigated the mechanics of slender structures and fluid-structure inter
 actions during postdoctoral positions at École Polytechnique Fédérale d
 e Lausanne (EPFL) and Boston University (BU). He earned his Ph.D. in Theor
 etical and Applied Mechanics from Sapienza University of Rome in 2016.
