There he is doing project management and data analysis concerning drinking water quality.
  • Ernest Gomis
  • For his undergraduate research at UCLA, Ernest further developed a project yielding Kinematically Reversible Magneto-Couette Flow. This used a magnetic field to generate current between parallel rings filled with conductive fluid, causing a low-Reynolds number flow that is kinematically reversible. Ernest further developed the conductive fluid and apparatus, and actually produced our very first movie of kinematically reversible flow. His research was funded by the Strauss Family Fund for Undergraduate Research. Ernest is currently working as an Analytical Chemist in Long Beach.
  • Alex Grannan
  • As a Ph.D. student from 2011-2017, I conducted laboratory experiments in the Spinlab and the IRPHE lab in Marseille to investigate libration-driven and tide-driven turbulence. I also investigated rotating and non-rotating convection in liquid gallium. In 2018 I joined Argonne National Laboratory as a postdoc where I developed software and applications for astrophysics and high energy physics simulations using the multiphysics code FLASH. In 2020 I transferred to nuclear engineering at ANL to develop a novel set of laboratory heat transfer experiments to validate nuclear reactor cooling blanket designs.
  • Emily Hawkins
  • For her Ph.D. work, Emily investigated the properties of rapidly rotating convective turbulence using the new large-scale NoMag device. She completed a novel experimental study to simultaneously measure velocities and heat transfer in rapidly rotating convection. In addition, Emily determined the length scales of turbulent core-style flows through a meta-analysis of available numerical and laboratory datasets. This work enabled her to constrain the conditions under which large-scale flows develop from small-scale turbulence in planetary dynamo settings.

  • Susanne Horn
  • Susanne studied convection in liquid metals, rotating convection including centrifugal buoyancy, and rotating magnetoconvection, to name a few, while at UCLA from late 2016 – 2019 via a DFG Postdoctoral Fellowship.  She is now a senior lecturer in the Centre for Fluid and Complex Systems at Coventry University in the UK.
  • David James
  • DJ is starting his PhD in EPSS in the fall of 2020. Until then, he will continue the development (aka the reanimation) of the DigiPyRo python script.  This script digitally rotates a movie around a selected axis point and allows for single-particle tracking within the digitally rotating frame. The project was originally designed to allow students to experiment with the Coriolis force by selecting their own rotating reference frame using DigiPyRo. However, it is proving to be well-suited for a number of other applications, many relevant to the DIYnamics project as well.
