Computer Systems Administration

Hello and welcome to the Department of Computer Science at Hofstra University.  The department's mission is to provide students with a strong foundation in the theory and practice of computer science.

As the Systems Administrator for the Department of Computer Science, I manage and coordinate all operational aspects of the department's computer systems and cater to the evolving needs of the department in collaboration with the Department of Information Technology.

The systems I manage include the Linux, Mac OS X, and Windows labs and the datacenter of the Big Data Laboratory.  (Visit for details on these facilities.)  Administration of these heterogeneous computer systems involves technical design, installation, configuration, troubleshooting, and automation.  Also, as caretaker of the Big Data Laboratory, I carry out administrative functions including installation and configuration of virtual machines, servers, and VMware system administration.
