Joseph C. Nichols, Ph.D - President and CEO

Dr. Nichols directs all of PlexLogic's business and financial operationa.  His previous experience has included developing one of the first implementations of Ethernet to run on a Z80 microprocessor, performing applied research on communication network and storage management optimization, running multimillion dollar commerical and Federal programs, and taking a software technology from initial research to market as part of a product with annual sales of over $3B.  Dr. Nichols is co-author of five textbooks on Microprocessor Programming and Interfacing as well as numerous academic papers published in mathematics journals. Joe was the co-founder of Digital Analysis Corporation which was acquired by Legent Corporation and subsequently acquired by Computer Associates. Dr. Nichols majored in Mathematics as an undergraduate at Wesleyan University and earned a Ph.D. in Mathematics from Duke University.

Elizabeth A. Nichols, Ph.D. - CTO for Metrics

Prior to starting PlexLogic, Dr. Nichols has founded two other software companies in the role of CTO and VP Engineering. The first company, Digital Analysis Corporation (DAC) implemented real-time data acquisition and analysis software for enterprise systems management. The second company, ClearPoint Metrics, implemented software products to automate the collection, computation, and communication of security metrics.  The first company DAC was acquired by Legent. When Computer Associates acquired Legent, the DAC products comprised the distributed technology infrastructure for Unicenter whose annual revenues went from $50M to over $3B during the time Dr. Nichols was with CA.  Dr. Nichols' earlier experience includes working at MIT's Draper Labs (Apollo intertial guidance), US Army R&D (war gaming), Computer Sciences Corporation (space mission optimization), and  various engineering positions in industrial process control.  She is co-author of five textbooks on Microprocessor Programming and Interfacing as well as numerous articles in both the trade press and academic journals.  Most recently she has served as co-chair of USENIX MetriCon Workshops and contributed to Andrew Jaquith's book Security Metrics -- Replacing Fear, Uncertainty, and Doubt and a chapter entitled "Beautiful Security Metrics" to the O"Reilly book Beautiful Security.  Dr. Nichols has a Ph.D. in Mathematics from Duke University and majored in Mathematics at Vassar College as an undergraduate.

Andrei Tchijov, CTO for Software

Andrei Tchijov has over 20 years of software product development experience in a variety of languages and environments. Since 1995 he has led development teams at Digital Analysis Corporation, Legent Corporation, Computer Associates International, and most recently at Sequation, Inc.  Equally proficient working on his own or managing a team of high-level developers, Andrei consistently delivers cutting-edge products.  At DAC, Mr. Tchijov led  the design and development of major new product releases to improve performance, scalability and functionality.  At Legent, he was the principal engineer for AgentWorks and the technical lead for the AgentWorks product line for network and systems managment based upon SNMP and CMIP.  When Computer Associates acquired Legent, Mr. Tchijov worked as a principal engineer for distributed infrastructure and real-time instrumentation, surveillance, correlation and modeling infrastructure for Unicenter TNG.  Andrei co-founded Sequation, Inc. to develop technology for Internet infrastructure with application in real-time data center operations management as well as strategic quality of service metrics design, deployment, and publication. He was the principal designer of the new patent-pending software to provide massively scalable grid-based solutions that maintain administrative ease with the exponential growth of hosts, services, users, and processing workload. He also managed a team of software product developers and established software engineering methodology for source code control, unit testing, defect tracking and continuous build/test automation.
