  Chiyoda-ku, Tokyo, Japan At Araya, I design and consult on machine-learning approaches for projects involving external clients, as well as pursue research into new machine-learning algorithms and techniques.The specific direction of research I am pursuing focuses on ways to translate the inner processes of machine learning algorithms into useful formats - both for knowledge transfer between algorithms, and for the automatic generation of explanations of the machine's 'thought process' in solving problems.

This ultimately relates to the subjects of machine awareness and attention. Show less

  Meguro-ku, Tokyo, Japan I am doing computational research into the origins of life - generative chemistry, models of the emergence of autocatalysis, and emergence of heredity. As part of this I am developing a shared framework for generative computational chemistry and analysis methods relevant to origins of life questions. I am also involved in helping to organize the newly formed Modeling Origins of Life (MOL) community (organizing workshops, weekly meetings, etc).

  Dense granular flows (with Prof. Wendy Zhang). I simulated the impact of a dense granular jet upon a target and compared with experimental measurements. I was able to observe the formation of a static deadzone, dependent on friction with the target. I developed a theory to describe the cone angle of the outflow from the target as a function of grain-grain friction. - Wet granular impacts (with Prof. Wendy Zhang).

I developed a theory to describe the cone angle of the outflow from the target as a function of grain-grain friction. - Wet granular impacts (with Prof. Wendy Zhang). I simulated the impact of wet granular droplets against a surface and measured the phase diagram of this process with respect to impact velocity and surface tension. I developed a model for saturated wet grains as distinct from grains with only a thin water film (so-called sand-castle sand) Show less

  - Simulations of coarsening in Type-I superconductors in the presence of a magnetic field. - The effect of the turbulent energy spectrum on pipe-flow friction in 2D. I performed 2D simulations using conformal mapping to test theoretical predictions of Gioia and Chakraborty that the momentum transfer in pipe flow could be derived from its turbulent energy spectrum. We collaborated with Prof. Walter Goldburg's group to confirm these results experimentally using soap films. -… Show more - Simulations of coarsening in Type-I superconductors in the presence of a magnetic field. - The effect of the turbulent energy spectrum on pipe-flow friction in 2D.

We collaborated with Prof. Walter Goldburg's group to confirm these results experimentally using soap films. - Complexity cascade in evolution. I proposed conditions which would be necessary for evolutionary processes to produce an open-ended increase in complexity. By using agent-based simulations, I was able to confirm that several distinct models could be constructed that satisfied these conditions and did in fact exhibit complexity increases consistent with open-ended development.
