Reseach interests
I am fascinated by a wide variety of problems concerning computer security and policy.
The primary focus of my research is to empirically analyze and model various types of online criminal activities to understand how we can better defend users. Domain names play a crucial role in illicit online ecosystems; for example, domain names are often used to fool users and to siphon user traffic by exploiting search engines or user mistakes. My Ph.D. thesis explores how users' typing mistakes can be leveraged to profit from abusive domain name registrations, and how to combat such registrations.
During my Ph.D., I have developed additional research interests related to censorship, reputation systems, blockchain governance, applied machine learning and Internet governance.
Present research projects I am working on include:
- Measuring how Traffic Distribution Systems are leveraged for online crime.
- Studying how Internet governance can help in the fight against abusive domain names.
- Modeling the evolution of governance in blockchain-based technologies.
You can learn more about my past and present research projects at the Research & Studies page or at my Google Scholar page.
Short Bio
I have obtained my B.Sc. degree in Computer Engineering from the Budapest University of Technology and Economics (BME) in 2010.
I was doing research under the supervision of Zoltan Faigl at the Mobile Innovation Center (MIK) from 2010 to 2011. In 2011-2012 I wrote
my thesis under the guidance of Mark Felegyhazi at the Laboratory of Cryptography and System Security (CrySyS Lab), and received my M.Sc. degree in Computer Engineering
from the Budapest University of Technology and Economics (BME) in 2012 awarded excellent with highest honors.
From 2011 to 2012 I worked at Sonrisa Kft. as a front-end and Java developer.
I joined the CrySyS Lab as a Research Assistant for 7 months in 2013.
Since 2013, I have been a Ph.D. student at Cylab under the supervision of Nicolas Christin
at Carnegie Mellon University.
