Position Description:

Internet Technologies Research

I manage the  Internet Technologies Research Group within the Communications Technology Laboratory (CTL) of the National Institute of Standards and Technology (NIST).   In that role I provide technical leadership to NIST's current research and standardization efforts in Trustworthy Networks, including Internet infrastructure Protection (e.g., Naming, Routing, Email and general Internet protocol security); next-generation Internet technologies  (e.g., IoT, IPv6, SDN / NFV); advanced security architectures and technologies (e.g., zero trust networks, applications of AI to network security and robustness); advanced security architectures for next generation wireless (e.g., 5G, O-RAN, 6G); and measurement, modeling, and analysis of behaviors within the critical network infrastructure.    

I have been a leader in NIST's research in next-generation network technologies since 1986.   While the advanced networking technologies under study have spanned a broad spectrum over my career at NIST (e.g., IP quality of service, Internet telephony, Internet security and key management, robust Internet routing / naming / addressing, mobile systems, programmable networks, optical networking, multi-protocol label switching, service discovery, pervasive computing, IP version 6, public safety communications, congestion control, cloud computing, quantum cryptography, zero trust networks, 5G / O-RAN security), the strategic plan has been consistent:  to research and apply advanced test and measurement techniques to improve the quality and timeliness of new networking technologies that address identified national priorities and/or have the greatest potential for fueling broad-based innovation in the Internet.

The goals of our Trustworthy Networks Program are tightly aligned with identified national priorities outlined in the National Cybersecurity Strategy and Implementation Plan, National Strategy to Secure 5G, National Standards Strategy for Critical and Emerging Technology Technologies and Federal Cybersecurity Research and Development Strategic Plan.

The technical work in my group spans a wide range of activities including basic research, design and analysis of consensus standards, development of rapid prototypes, reference implementations and test tools for implementors, publication of guidance documents to foster adoption, design and operation of international conformance and interoperability testing programs to assist deployment.   

I serve as the primary external representative for most of these efforts and have represented the work of my group to numerous industry, government, and academic audiences, including congressional committees, inter-agency groups, international governments, VCAT and NRC review panels as well as other agency collaborators.   Examples of such interactions include House Science Committee, Federal CIO Council, Federal CIO, OSTP, NITRD, OMB, ONCD, ONDI, GSA, NTIA, FCC, CSRIC, Internet Engineering Task Force (IETF), North American Network Operators Group (NANOG), American Registry for Internet Numbers (ARIN), O-RAN Alliance, ATIS, ISO/IEC.    

I current serve as co-chair of the NSTC Networking and Information Technology Research and Development (NITRD) Large Scale Networking Group and member of the executive committee for the Federal IPv6 Task Force as well as a participant in many other US Government inter-agency committees on networked information technology issues.

My management experience as a group leader at NIST includes managing a staff of computer scientists, electrical engineers, mathematicians, and administrative personnel engaged in a wide variety of research and support tasks.  In the time that I have been a manager, the projects and programs in my group have been supported by DHS S&T, NSA, LTS, DARPA, NSF, OMB, GSA, NIST ATP, DISA, NIST NAMT, NIST OLES and NIST IMS research funds.
