I'm thrilled to be joining Intel to work on the performance of everything, apps to metal, with a focus on cloud computing. My dream is to turn computer performance analysis into a science, one where we can completely understand the performance of everything: of applications, libraries, kernels, hypervisors, firmware, and hardware.

As more organizations adopt generative AI and cloud-native technologies, IT teams confront more challenges with securing their high-performing cloud applications in the face of expanding attack surfaces. Likewise, with observability of systems that run AI models, organizations can predict and control costs, performance, and data reliability.
