My current places of 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. I currently teach a course in the  Azrieli College of Engineering in Jerusalem. I have also taught similar courses at the Holon Institute of Technology and in the Israel Tech Challenge project.

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.
