Ethan giving a talk at an open source meetup in Boston.

I'm currently co-founder and CTO of Nash, a non-custodial exchange and asset management platform for cryptocurrencies and other tokens. I have a PhD in Computer Science from Stanford and have published articles in leading journals and conferences, such as Nature, CHI, EMNLP, and AAAI. Previously, I co-founded Proxino, a web analytics company funded by Y Combinator.

Companies

I have co-founded two notable companies.

Research

During my PhD I did research at the intersection of Human-Computer Interaction, Programming Languages, and Natural Language Processing. I led work on more than ten published projects, most of which involved significant systems building. My full publication record is available on Google Scholar but I've included a few of my favorite research initiatives below.

Empath

Empath is a text analyis tool powered by machine-generated lexicons. This work won a Best Paper award at CHI 2016.

Trends in the Public Perception of AI

We analyzed how public views about AI shifted over a 30-year period using a large corpus of articles from the New York Times.
AAAI 2017
47 citations

Maria

We used LSTM models to predict HLA class II antigen presentation. This work was led by my partner Binbin Chen.
Nature Biotechnology 2019

Job Talks

I interviewed for tenure-track faculty positions at MIT, Harvard, and Berkeley before deciding to focus completely on my startup. Meeting and explaining my ideas to so many incredibly smart people was a unique and valuable experience.

Open Source Work

I've created a number of open source projects on Github, some of which became popular. A selection of these are below.

Neon Wallet

Neon is a light wallet for managing digital assets on the NEO blockchain. I created it in 2017 when I co-founded the open source group CoZ. It is now managed by other open source contributors. At one point Neon had more than 100,000 active users.
Published 2017

TypedJS

An experimental project to help JavaScript developers fuzz-test their programs using type annotations, inspired by Haskell's QuickCheck. This was back before type checking JavaScript was popular.
Published 2012

Gajure

A framework for implementing Genetic Algorithms in Clojure. I made this in undergrad after publishing some other work on automatically fixing program bugs with evolutionary algorithms.
Published 2010

Press

My research and industry work has been covered in venues such as the Globe and Mail, CNBC, Endgadget, TechCrunch, Canadian Public Radio, and New Scientist.

Essays

From 2009-2012 (college to early startup years) I wrote a number of short essays. I do not necessarily endorse the views of my past self. I have also written things on Medium.
