Aleksandra Korolova

Aleksandra Korolova I am a WiSE Gabilan Assistant Professor of Computer Science at USC. Previously, I was a Research Scientist at Google, a Privacy Advisor at Snap, and a Ph.D. student in Computer Science at Stanford.

My research develops and deploys algorithms and technologies that enable data-driven innovations while preserving privacy and fairness. I also study and address the societal implications of algorithms and machine learning.

Current PC(s) and Service: Member of the Design Committee for OpenDP, a community effort to build tools for enabling privacy-protective analysis of sensitive data. Steering Committee of the National Academies of Sciences, Engineering and Medicine for “Challenges and New Approaches for Protecting Privacy in Federal Statistical Programs” (2019).

News: Recipient of the NSF 2020 CAREER Award. Received a Security and Privacy Research Award for research on differential privacy from Google, a Mozilla Research grant for studying ad preference controls, an NSF SaTC Medium for "Understanding the Privacy and Societal Risks of Advanced Advertising Targeting and Tracking", and an NSF SaTC Frontiers for "Protecting Personal Data Flow on the Internet". Selected as a VMware Research Fellow for “Data Privacy: Foundations and Applications” at the Simons Institute (see my recent talk on "Societal Concerns in Targeted Advertising"). Invited Speaker for WSDM 2019 and Trustworthy AI Symposium.

Prospective Students: I have open PhD and post-doc positions for motivated students with an interest in privacy, algorithmic fairness, and societal implications of AI.

I received my Ph.D. in Computer Science from Stanford, where I was a Cisco Systems Stanford Graduate Fellow advised by Prof. Rajeev Motwani (RIP, Rajeev) and Prof. Ashish Goel. My Ph.D. thesis focused on protecting privacy when mining and sharing user data, and has been recognized by 2011-2012 Arthur L. Samuel Thesis Award for the best Ph.D. thesis in the Computer Science department at Stanford. While at Stanford, I was fortunate to intern at Microsoft Research, Facebook, Yahoo! Research, and PARC.

I grew up in Latvia and graduated from Riga secondary school #40, spending fun weekends preparing for math olympiads at NMS and learning algorithms at Progmeistars. I am indebted for the many opportunities I have had to my family, amazing teachers at the above institutions, and to the George Soros Foundation. My outstanding high school mathematics teacher, Viktor Glukhov, now teaches and organizes math circles in London. If you visit or live in Riga, rent an apartment or office space in the center of Riga.

I loved spending my college years at MIT, and especially enjoyed the classes taught by Prof. Patrick Winston. I first tried doing research in Dan Spielman's error-correcting codes class and Joe Gallian's Duluth REU. At Stanford, I enjoyed learning randomized algorithms, algorithmic game theory, cognitive science and design thinking. I also had fun advocating for graduate student interests as part of the Graduate Student Council, and serving as a mentor and Center for Teaching and Learning liason for Computer Science TAs.

In my free time, I enjoy traveling, skiing, and playing tennis.

I proudly support MEET, MIT, EFF, and The Markup.
