Publications (Peer-reviewed/arXiv)

I frequently submit research work to renowned venues across various domains, including: (i) security (USENIX Security, IEEE S&P, NDSS, CCS), (ii) privacy (PETS), and (iii) web measurement (WWW, ACM IMC). Below, I highlight some scholarly works published in reputed venues, as well as others currently available on arXiv while under review at conferences. For a complete list of scholarly works, including those beyond published and arXiv submissions, please refer to the CV page.
