In addition to being a computer science professor, I am a consultant on issues related to computer storage systems and, more generally, computer systems. My curriculum vitae is available online, as are details on my research group, the Storage Systems Research Center at the University of California, Santa Cruz.
Since 2001, I have consulted with several Silicon Valley companies on storage system and file system design issues. These issues range from questions of how to implement petabyte-scale storage systems using commodity storage devices to ongoing consulting on next-generation file systems. I would be happy to help your company explore new directions in advanced file system and storage system design; please contact me at elm «at» mac·com.
I have also served as an expert witness in several intellectual property lawsuits. In doing so, I investigated prior art for patents and analyzed source code to determine whether it infringed the patents at suit. I have prepared expert reports on patent validity and infringement, and have testified in court on my findings. If you are interested in having me serve as an expert (testifying or consulting), please contact me at elm «at» mac·com. I would be happy to provide references from attorneys who have worked with me on prior cases.
