Before that she served four years as Area Director (AD) of the transport area on the Internet Engineering Steering Group (IESG). She is an author of twenty RFCs, including RFC 6817 on Low Extra Delay Background Transport (LEDBAT), RFC 7786 and RFC 7837 on Congestion Exposure (ConEx), and RFC 9768 on More Accurate ECN Feedback (AccECN). She is co-chair of the Measurement and Analysis for Protocols Research Group (maprg) in the Internet Research Task Force (IRTF).
