Warren "Ace" Kumari
Pronouns: he/him

Warren Kumari currently works for Google in the Internet Evangelism group, and has been with the company since 2005. He has over 20 years of experience in the Internet industry, ranging from tiny start-up ISPs to large enterprises. Prior to serving as IETF Operations and Management Area director Warren chaired the OpSec, OpsAWG, DPRIVE, DANE and CAPPORT working groups.

Warren is also active in ICANN, serving on the Security and Stability Advisory Committee (SSAC), and is a consultant to USC/ISI (the operator of B-Root). He also serves as SSAC liaison to the ccNSO TLD-OPS group.

Disclosure: I am employed by Google LLC, and am a no-fee consultant to University of Southern California (USC) / Information Sciences Institute (ISI). Other than a small payment (~$500) for reviewing a book on YANG, I receive no other funding, nor have I ever been asked or felt pressured to support an employer (or other) position.
