Hi! I'm Onur Varol, a postdoctoral researcher at the Center for Complex Network Research in Northeastern University Networks Science Institute.
My research activities focus on modeling user interactions, leveraging online data across multiple platforms to understand conscious and unconscious behaviors. I am working with Albert-László Barabási on quantifying performance and success online (Q-Factor) as well as individual well-being. I also work with Tina Eliassi-Rad for developing novel machine learning models. Our L2P approach exploits the pairwise relationships between instances to provide auditing tools for algorithmic fairness and to address challenges in heavy-tailed regression problems.
During my PhD at Indiana University, I was a proud member of NaN group and focused on the detection of persuasion campaigns and social bots using the tools of machine learning, data mining, and network analysis. I developed a social bot detection system Botometer (aka BotOrNot). I closely worked with Filippo Menczer, Alessandro Flammini, and Emilio Ferrara on various projects related with detection of manipulation on social media. Details on projects can be found in research and publications sections.
