This is my online portfolio. Feel free to get in touch.

About This Site:
My Live Portfolio

The following bite-sized sections will tell you a lot about me in a few minutes:

  • Micro bio.
  • A blog about my projects.
  • Current research work.
  • Two-page CV.
  • Talks related to my work.
  • Open-source projects.
  • Other random stuff.

A portfolio of work is a curated experience. It's an applicant's chance to shape the way that I'm viewing his or her approach, methods, process, and best thinking.

Who's Jo-fai Chow?
A Guy who Loves Machine Learning and Data Visualisation

I am currently a data scientist at H2O.ai, a venture-backed technology start-up in Silicon Valley.

Before joining H2O.ai, I was in the business intelligence team at Virgin Media where I developed data products to enable quick and smart business decisions. I also worked remotely for Domino Data Lab as a data science evangelist promoting products via blogging and giving talks at meetups.


The ability to take data - to be able to understand it, to process it, to extract value from it, to visualize it, to communicate it - that’s going to be a hugely important skill in the next decades.

Open-Source Projects

I enjoy contributing to the open-source community in my spare time. I am particularly interested in data mining and visualisation projects. My favourite programming languages are R, Matlab and Python. I am also learning how to leverage the power of JavaScript, CSS and HTML5 for web development. My recent projects include:

Life Before Silicon Valley:
A Data Geek in Water Industry

I have a background in water engineering. Before my data science journey, I was an Engineering Doctorate (EngD) research engineer at STREAM Industrial Doctorate Centre working on machine learning techniques for drainage design optimisation. The project was co-supervised by University of Exeter and XP Solutions. During that time, I won the best young researcher award at an international conference. For more information, see this Prezi.

Prior to my EngD project, I was an asset management consultant at SEAMS where I assisted utilities companies in UK and abroad with their infrastructure investment planning. I also holds a MSc in Environmental Management and a BEng in Civil Engineering.

Shaping careers, delivering innovation. Working with industry on transformative research to underpin a sustainable water future.

My Blog:
Blend It Like a Bayesian!

I discuss my research and open-source projects in details using my blog (instead of this personal page). It is one of R-bloggers' 550+ contributing blogs. Interested in the behind-the-scenes stories of my projects? Go to my blog

Back in 2014, I wrote a guest blog post for H2O.ai and Domino explaining how to use their technologies for a Kaggle (data mining) competition.
