About

I am a postdoctoral researcher at the University of Sao Paulo working in Computation Fluid Dynamics (CFD) of viscoelastic flows.  I obtained my PhD degree in Applied Mathematics in the Department of Mathematics at University College London (UCL) in 2019. I have been awarded the British Society of Rheology Vernon Harrison Award for the most distinguished PhD thesis in rheology (my thesis can be found here). My research interests are non-Newtonian fluid dynamics (fluids that do not behave like the standard),  rheology (the science of deformation) and transport phenomena (transfer of physical quantities such as momentum, energy, and mass).  In my PhD, I was under the supervision of Professor Helen J. Wilson and we were interested in studying flow instabilities in viscoelastic materials (fluids that behave like both elastic solid and viscous liquid), shear-thinning fluids (for instance, chocolate), and thixotropic fluids (structured fluids with time-dependent viscosity).

I have an MsC and a bachelor degree in Chemical Engineering, both awarded by the National Autonomous University of Mexico (UNAM). I used to work as a research assistant at Materials Institute Research (IIM-UNAM) under the supervision of Professor Octavio Manero Brito. We both were interested in the behaviour of micellar solutions under flow. We used structural models and irreversible thermodynamics for its study, and our research led to the publication of a paper and a book (see Publications menu for further information).

I am a former member of Chalkdust, a magazine for the mathematically curious, for which I wrote many online blogs (from maths in football to beer, among other different topics).

I have a general interest in science, and if it involves mathematics, that would make me happier. I like teaching, football, and dogs (as my picture suggests). I also have a Youtube channel called Hugo Castillo, where I upload videos of the gigs I have attended.
