John Levy, Ph.D.

My areas of expertise are software and computer engineering.

I have two particular areas of specialty:  The first is computer hardware design, particularly input/output, storage and hard disk drives.  The second is software, particularly operating systems, PC BIOS, storage networks and software development.

I have a Ph.D. in Computer Science from Stanford and engineering degrees from Cornell and CalTech.

I have been engaged as an expert in more than 60 cases.  In the past four years, I’ve testified at trial one time and been deposed seven times.

In prior years I have also consulted for the Court as a neutral expert in three cases.
