On behalf of SUSE, I am nominating Jan Dubois for the KubeCF Project Lead in the Application Runtime PMC.
Jan has worked on running Cloud Foundry in containers since the initial public release. At first using LXC with the Cloud Foundry DEA in the Stackato fork by ActiveState, then with HPE Helion Cloud Foundry and Diego, and SUSE Cloud Foundry on Kubernetes. He's been contributing to the KubeCF project since its inception. Prior to that he was a maintainer for Perl 5 on Windows, and even longer ago living as a physicist amongst finance people.
