I have been involved in Linux development since the early nineties and I am co-maintainer of the Linux SCSI subsystem and frequent contributor to the block I/O layer and libata.

I work as architect in Oracle's Linux Kernel Engineering group. My main focus is implementing support for future storage technologies in Linux. I also represent Oracle and Linux in T10 which governs the SCSI family of protocols, and I participate in other standards efforts such as SNIA and NVM Express.

Prior to Oracle I worked at Wild Open Source, a small consulting firm that I co-founded along with several Linuxcare expatriots. Among other things I worked on the base Linux distribution for Hewlett–Packard's XC clustering products and the Altix kernel for SGI.

Before WOS I was Staff Scientist with Linuxcare. I worked on bringing up Linux on HP's Itanium 2-based Integrity servers & workstations and I was part of the original team at SGI that ported the XFS filesystem to Linux.

From 1995 to 2000 I was head of the IC1&2 computing department at Aalborg University in Denmark. I also developed the GNOME Display Manager, helped bootstrap the PA-RISC Linux port, and co-founded the Danish SunSITE.

I studied physics and computer science at Aarhus University.
