Bio

Ioannis Koltsidas is a Research Staff Member in the Cloud and Computing Infrastructure department at the IBM Zurich Research Lab. He is currently interested in next-generation Flash-enabled storage systems, exploitation of Flash memory in host servers, as well as applications of Storage-class Memories, such as Phase-Change Memory. His interests also include distributed scale-out file storage (GPFS, HDFS) and extensions thereof based on open-format magnetic tape. Some of the latest projects he has been involved in include the IBM FlashSystem, the IBM Easy Tier Server for the DS8000 series and the IBM LTFS Enterprise Edition.

Previously, Ioannis received his PhD in Computer Science from the University of Edinburgh, where he was a member of the Database Group at the School of Informatics. His research was supervised by Prof. Stratis Viglas. The focus of his thesis, titled "Flashing Up The Storage Hierarchy", was on database systems and data-intensive systems in general that employ novel storage media, such as NAND Flash SSDs and use novel algorithms and data structures to boost I/O performance. Prior to that, Ioannis completed his undergraduate studies at the Electrical and Computer Engineering Department of the National Techinical University of Athens (NTUA) in Athens, Greece, where he majored in Computer Science.
