Confined chemical reactions
In several scenarios, spanning from the lotus leaf, to lab-on-a-chip devices, chemical reactions occur within confined scenarios such as pores, droplets, and thin films. Therefore it is crucial to assess their dynamics under diverse transport and chemical conditions

(Active) Polymers
What happens when a polymer is translocated across a porous medium? Which interplay we can expect between the interanl degrees of freedom of the polymer and the pore medium?
Active polymers are made of monomers that are active and they induce a force tangential to the backbone. The activity can induce novel dynamical regimes absent at equilibrium. Within this project we tackle the dynamics of sigle active filaments in different scenarios to explore the peculirarities of this intriguing active systems.

Electrokinetics
The transport of electrolytes across varying-section channels and pores is crucial for several technological applications, such as blue energy harvesting devices, desalination membranes, particles-seperation devices as well as for biological scenarios such as ionic channles, acquaporines and nucler pores. Here we look for novel transport regimes that can be obtained by propelry tuning the geometry of the channl and the properties of the electrolyte.

In many circumstances, spanning from oil recovery, soil permeation, up to blood flow and cereals in sylos the transport is controlled by constrictions along the flowing direction. Here, the main question is the dependence of the transport on the geometry of the pore.

Molecular Motors
When molecular motors actively displace inside the cell the induce a local flow of cytoplasm. Such a flow can induce fluid-mediated interactions among the moleculr motors. Moreover, the crowded envoronment of the cell as well as ist geometry (think of axons) may tune the performance of molecular motors
