Dr. Ha has extensive experience in computer systems, including practical machine learning and deep learning systems, network and distributed systems, mobile systems, internet protocols, LTE/5G networks and security, video streaming, and storage systems. He co-founded multiple startups and developed CUBIC (now standardized as RFC 9438) as part of his PhD research. CUBIC serves as the default TCP congestion control algorithm on the Internet and is utilized by billions of devices worldwide on a daily basis.
