Education, Outreach and Broader Impacts
Integrating Research & Teaching: The introduction of digital network twin has been added in the newly developed course CSC/ECE Advanced NextG Network Design at both Department of Computer Science and Department of Electrical and Computer Engineering, North Carolina State University. The introduction of using neural networks for digital network twin optimization has been added in the graduate class ECE 553/653 Neural Networks at University of Miami.
Cultivating Interests among High School Students: PI has regularly organized the Summer Residential Camp – Seeing through a Digital World, inspiring high-school students to explore the intricate workings of complex network systems and simulations within the digital realm. Several rising senior high school students from Green Level and Enloe High Schools in Cary, NC also worked in the PI’s lab on topics related to digital network twins. To name a few: Rohit Kota, Maulik Verma, and Jaden Mu.
Facilitating Undergraduate Research: Several NCSU undergraduate students worked in the PI’s lab on topics related to radio access networks and data generation. To name a few: Jordan Miller, Nitesh Kanamarlapudi, and Krushi Bandam.
Dissemination to Communities of Interest: PI has co-organized The 48th IEEE COMPSAC Workshop on Digital Twins for the Metaverse and IEEE ICC Workshop on Edge Learning over 5G Mobile Networks and Beyond to share cutting-edge research, foster collaboration, and advance the understanding of digital twins and edge learning technologies.
