I am a researcher working in the PoreLab group at the Physics Department of the University of Oslo. I obtained my BSc and MSc from the Federal University of Pernambuco, Brazil and my PhD from the University of Oslo, Norway. My main areas of activity are fluid mechanics (flow in porous media, vortex dynamics in classical fluids and hydrodynamic instabilities) and fracture dynamics (fracture nucleation and propagation in brittle materials). Additional info: ResearchGate profile, University of Oslo personal page, and Google Scholar profile.
I was recently interviewed by TV Jornal SBT (Brazil). I have spoken a little bit about some of our research activity in Norway. I have shown the TV friendly Flying Chain experiment and also commented how the motion of air through a facemask really is a problem of flow in porous media.
Slow drainage flows in porous media often present a very interesting intermittent invasion dynamics. This was the topic of a paper we recently published in Frontiers in Physics. This dynamics can be seen in a fun kitchen experiment using a teabag! Titan has published a popular science article where I explain how this can be done.
I made a little Geogebra applet to integrate the SIR equations used in the modeling of a pandemic. This tool is published openly and the user can tune the model parameters using a slider. It is very convenient to see how a reduction in the reproduction number R0 leads to the flattening of the infection curve.
A popular science article was published about our research on the flying chain. We also recorded a video to help with the explanation. This is a very curious effect, almost impossible to believe that a long chain dropped from a given height would behave that way. Good fun!
The flying chain takes off once again! Our paper on the mechanisms of the flying chain fountain just got published in Frontiers in Physics. We have analyzed numerically, theoretically and experimentally the physics of a pretty weird Youtube viral video. Science communicator Steve Mould showed that a chain of metallic beads moves in a most unexpected manner, when dropped from a container at a given height. We have shown that the structure and dimensions of the chain and container play an important role in this curious system.
I was honoured to receive an InterPore Rosette award "in recognition for sustained and valuable services to The International Society for Porous Media". The award was given during the 10th International Conference on Porous Media and Annual Meeting of InterPore which took place in New Orleans, USA on May 2018.
In connection with the Student Affairs Committee of InterPore, I have helped to organize a set of activities for the students, postdocs and early career researchers during the 10th InterPore meeting in New Orleans, USA. A description of those activities can be found here.
Big news! Our paper “Verification of a dynamic scaling for the pair correlation function during the slow drainage of a porous medium” has just been published by PRL (Physical Review Letters). In this paper we have experimentally verified a 30 years long prediction about how the relative probability of invasion of a pore in a porous medium varies with space and time. The article has been published as Open Access (free for all!) and can be found here.
I am now collecting contributions for our recently created Gallery of Porous Media Art. This is a free space dedicated to the divulgation of stunning images and videos related to porous media research. If you would like to collaborate with material for the gallery, please contact me.
Our article “Critical behavior in porous media flow” has been published by EPL (Europhysics Letters). This was project in which we have addressed the statistics of burst invasion events in porous media and also the power spectrum of pressure fluctuations associated with the bursts. You can find the article here.
