Jacob Ratkiewicz



I am currently a software engineer at Google.

I received my Ph.D. in Computer Science from the School of Informatics and Computing at Indiana University. There, I was a member of the Center for Complex Networks and Systems Research (CNeTS), and of the Networks and Agents Network (NaN) group, led by my advisor Prof. Fil Menczer. I was also involved with the Truthy and Givealink projects. The general focus of my research was Web Dynamics. You can read my doctoral thesis.
