# Introduction: Ernesto Gonzales

Hi all,

My name is Ernesto Gonzales. I'm an analog circuit designer. While I already have a MSc in it and I love it, I also would like to spend the last half of my 20s studying some more math.

At my alma mater, there's a school of thought for designing electronics called "Structured Electronic Design". There seems to be a possibility that Category theory could be applied to it. But if not, learning something new is also a win for me :)

Comment Source:Hi, Ernesto! There are some cool connections between analog circuits and category theory. I wrote a paper on this topic with Brendan Fong back when he was my grad student: * John Baez and Brendan Fong, [A compositional framework for passive linear circuits](https://johncarlosbaez.wordpress.com/2015/04/28/a-compositional-framework-for-passive-linear-networks/). It has some mistakes that we're trying to fix... this week! A lot of this stuff generalizes to circuits with non-passive components, and I've started working on those with some other students: * John Baez, Brandon Coya and Franciscus Rebro, [Props in network theory](https://arxiv.org/abs/1707.08321).
