Roberto Pineiro is a PhD student working on buffer management for predictable performance with Professor Scott Brandt.  Before graduate studies at UCSC, he earned a B.S in Mathematics and a M.S. in Computer Engineering from the University of Puerto Rico- Mayaguez.

Anna Povzner received her Ph.D. working with Prof. Scott Brandt on efficient guaranteed disk I/O performance management. Her research interests include real-time systems, storage quality of service, and storage performance management. She is a Research Staff Member in Storage Systems group at IBM Almaden Research Center.

Ian works on the WikiTrust project, who also has a soft spot for coffee. When he is not obsessively monitoring logs or thinking about databases, Ian likes to build cool toys like an Arduino-based networked toaster or spend the afternoon biking around Santa Cruz.

I am a computer science Ph.D. candidate at UC Santa Cruz where I do research on hard real-time multiprocessor scheduling with the SRL.

Outside of the SRL, my thesis is focused on making it easier to write correct, high-performance code, with an emphasis on parallel programs. To that end, I am currently researching the usability of different parallel and concurrent programming concepts and course materials.

Dimitris Skourtis received his Ph.D. on predictable performance for flash storage. His research interests include flash-based storage systems, storage QoS, and resource management. Dimitris has a degree in Mathematics from the University of St. Andrews. He has completed two internships at VMware working on resource management. He is a member of the DRS group at VMware.
