Dr. Dennison joined NVIDIA in September of 2013 and leads the Network Research Group.  His current research interests include large networks of GPUs, switch micro-architectures, network-on-chip and photonic interconnects.  At, NVIDIA, he was the principal investigator for the DesignForward project which was responsible for several GPU shared-memory concepts such as NVSHMEM and NCCL.  His team proposed development of a GPU shared memory fabric and developed the first NVSwitch architecture.

Prior to NVIDIA, he worked on software systems such as high-performance distributed applications, database scaling for the cloud and software-defined networking. He also architected and led the development of the ASIC chipset for the Avici Terabit Router which utilized a 3-D toroidal network. At BBN, Dr. Dennison was the principal investigator for MicroPathfinder, a wearable computer that connected to other wearables over a very low power RF network.
