I work in the Storage Systems Research group at IBM Almaden Research Center, San Jose, CA. I have been working in the area of Storage Systems since 1997. Most recently, I worked on IBM GPFS Storage Server, previously known as IBM GPFS Native RAID, about which I gave an invited talk at LISA'11. Please see my publications page and patents page for additional information. Prior to 1997, I worked in the areas of Industrial Automation Systems (such as, SCADA) and Biomedical Embedded Systems.
