Boris Gorelik



my name is Boris Gorelik. I’m a data scientist, algorithm developer, data visualization enthusiast and occasional lecturer. I have been solving data-intense problems since 2001. I have been teaching data visualization since 2015.

Write me to

Occasionally, I talk about my job. If the talk was recorded, you can find it in this playlist. I love talking about data science, social networks, and data visualization. If you want to invite me, just drop a line.

Where do I work?

Since May 2014, I’m a data scientist at Automattic – the company behind and other projects. At Automattic, I have the chance to analyze fascinating data generated by more than 120,000,000 users.

I also teach data visualization courses.

What did I do before my current position?

Until 2014 I worked at RSA – the security division of EMC. At RSA, I was a co-developer of an online outlier detection algorithm named TAnDeM. This algorithm is designed for cases where the data are cheap; the labels are expensive, and the service providers do not tolerate black box solutions.

Before joining RSA, I worked for more than four years as a senior bioinformatician and later on, as head of software and bioinformatics in Procognia – a small biotech company. Before Procognia, I was a bio-mathematical simulation person and pharmacokinetics/pharmacodynamics expert in Optimata. I worked in Optimata for about two years, just after graduating my Ph.D. in computational chemistry from The Hebrew University of Jerusalem.

Data is NOT the new gold

Comparing something to gold implies that it is scarce, unchangeable and has zero utility value. Data is neither, it’s ubiquitous, ever-changing and has some utility value of its own.
