my name is Boris Gorelik. I’m a data scientist, algorithm developer, data visualization enthusiast and occasional lecturer. 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 110,000,000 users. My current passion is the social aspects of user engagement. In this talk, presented in 2015, I talk about this research. One year later, I presented another set of interesting results at WordCamp Israel. You can find these results in my blog post.

My team has a public blog,, in which I, and my teammates share data insights from our work at Automattic.

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 Univeristy of Jerusalem.
