Spotlight On: Juan Ochoa

Welcome to our interview series with a twist — where researchers choose from a pool of questions which ones they want to answer. It’s a chance to get to know them and their work from a more personal angle.

Today in the spotlight: Juan Ochoa, a new member of the CSH Foundations group. We’re excited to welcome him to CSH and to kick off the series with his personal take on science, networks, and the unexpected!

What are you currently working on, and why is it exciting to you?

I am currently working on understanding a given economy by looking at its systemic risk at different scales and thinking about possible analogies for belief dynamics and social systems from a statistical physics point of view. It is very exciting to see how models that were initially developed to understand fundamental physics problems can now be adapted to address social or economic systems.

Which tools or methods do you use most in your work?

Network theory and statistical physics.

What brought you to science in the first place, and how did you end up at CSH?

I started by studying physics motivated by a great interest in understanding how nature works. After realizing that the tools provided by physics and mathematics could also be applied to everyday life and real-world problems, I decided that I wanted to work in Complex Systems. Then, CSH naturally appeared as the place where I could focus my research in these directions.

What's the most unexpected place your work has taken you–intellectually and geographically?

Vienna!

If you could invite any historical figure to a research meeting at CSH, who would it be–and what would you talk about?

Ludwig Boltzmann, to see his perspective on many research fields that are currently based on his work.

What's the one concept in Complexity Science you think everyone should know–and why?

The fact that the system’s properties emerge from the interaction between its constituents and therefore the system is much more than the sum of its parts. It gives a different perspective when looking at many things, even in everyday life.
 
On the other hand, it is impossible not to think about the concept of entropy and its role in all the processes we can perceive!

What's your favorite place in Vienna so far?

The Vienna forest!
