Frank McSherry is a prominent computer scientist specializing in privacy, data processing systems, and cryptography. He is best known for his foundational contributions to differential privacy, particularly for developing the concept of local sensitivity and the sample-and-aggregate framework, which are crucial for making differential privacy practical for real-world data analysis.
Career and Affiliations:
- He spent a significant portion of his career at Microsoft Research (in Silicon Valley and Cambridge, UK), where he conducted much of his seminal work.
- He is a co-founder of Privacera, a company focused on data security and governance, and has also been involved with other startups in the data privacy space.
- He has held an adjunct professorship at Carnegie Mellon University, contributing to its strong academic presence in the field.
- He is known for his collaborations with other leading researchers, including Kobbi Nissim and Adam D. Smith, with whom he co-authored the foundational paper on local sensitivity.
Key Contributions:
- Differential Privacy: His work has been instrumental in moving differential privacy from a theoretical concept to a practical tool. He has focused on making it efficient and usable for large-scale data analysis.
- Systems and Algorithms: He is a strong advocate for building practical systems that implement privacy-preserving techniques. He has worked on systems like Prio (for private data aggregation) and has contributed to the development of Apache DataSketches.
- Public Commentary: He is an active and often outspoken commentator on privacy and technology, frequently critiquing industry practices and advocating for stronger privacy guarantees. He is known for his clear and sometimes blunt explanations of complex technical issues.
Personality and Style:
- He is known for his direct, no-nonsense communication style, both in academic papers and public talks.
- He is a strong proponent of rigorous, provable privacy guarantees over ad-hoc anonymization methods.
- He often describes himself as a "nerd who builds run-time systems," highlighting his focus on the practical engineering side of privacy.
In summary, Frank McSherry is a leading figure in the field of privacy-enhancing technologies, whose work has had a profound impact on how we think about and implement data privacy in modern systems.
