 Dr. Alexandra Gorgevska is a Professor of Biotechnology at Palm Beach Community College. She received her Ph.D. in Biochemistry from the Department of Chemistry at Wayne State University specializing in DNA-protein cross-links. Her research involved investigating and discovering novel mechanisms and structures of formalin cross-link formation between DNA and proteins that form as a result of the fixation process during biopsy preservation. She has worked as a research technician in the Vascular Research Laboratory at William Beaumont Hospital and a research fellow at the University of Michigan in the Physiology Department.
She was a post-doctoral fellow at the National Institutes of Health in the National Institute on Aging, where she investigated the mechanisms of premature aging disorders, primarily that of Werner's Syndrome. She is presently involved with developing and expanding a biotechnology curriculum to meet the needs of the emerging bioscience community. [Faculty web page]

 Professor Lilian R. Jordan is a tenured professor of Physics and Astronomy at the Palm Beach Gardens campus. She has been a full-time faculty member there for over eleven years, and prior to that was an adjunct faculty at the Boca Raton campus. She has a keen interest in the implementation of technology in the physics curriculum and the development of innovative methods of teaching physics. Professor Jordan received her M.S. degree in Physics from Florida Atlantic University and went on complete the coursework requirements at the PhD. level. As a research assistant, Professor Jordan spent several summers at the National Synchrotron Light Source (NSLS) of Brookhaven National Laboratory in Long Island, NY as well as the Center for Advanced Microstructures & Devices (CAMD) at Louisana State University. Her research was based on photoemission studies of surface energy states of copper-gold alloys. She also collaborated on-site with researchers at the University of Messina, Italy, developing a computer code for modeling surface energy states of copper, gold and their alloys.
Professor Jordan is an avid traveler and has visited several countries abroad including United Kingdom, France, Italy, and Greece. In 2000 she and her husband embarked on a mission to visit Isaac Newton’s birth home in Woolsthorpe, Lincolnshire, England as well as Trinity College, Cambridge, where he attended as a resident student and was later appointed Lucasian Professor of Mathematics. In a prearranged visit with the Librarian at St. John’s College Library, Cambridge, she was able to see Newton’s original handwritten manuscript of the revolutionary book he authored, “Philosophiæ Naturalis Principia Mathematica” as well as several other original documents of interest.

Claude R. (Russ) Joyner II is the Technical Fellow for Space Systems and Mission Analysis for Pratt & Whitney Rocketdyne. He obtained his Master of Science in space studies from the University of North Dakota in 2001 and his Bachelor of Science in aeronautical engineering from Embry-Riddle Aeronautical University in 1980.
Pratt & Whitney Rocketdyne, Inc., a part of United Technologies Corp., Pratt & Whitney, is a preferred provider of high-value propulsion, power, energy and innovative system solutions used in a wide variety of government and commercial applications, including the main engines for the space shuttle, Atlas and Delta launch vehicles, missile defense systems and advanced hypersonic engines.
Joyner provides the engineering expertise within United Technologies and Pratt & Whitney Rocketdyne concerning launch vehicle analysis and integration, hypersonic vehicle analysis, orbital mechanics and mission requirements. He is also the lead in the application of integrated concurrent engineering and implementation of Preliminary Multidisciplinary Design Optimization at Pratt & Whitney Rocketdyne.
Joyner has several types of rocket propulsion systems: liquid, solid, electric and nuclear. He is the mission analysis lead for hypersonic missile systems, hypersonic air-breathing systems, including cruise and access to space applications. He is a primary contributor to space propulsion system definition, hypersonic propulsion mission analysis and in the modeling of space systems, missile systems, and air vehicle systems relative to the optimization of the propulsion system.
Joyner has authored or co-authored over 40 papers and articles covering the analysis and design of space system and launch vehicle propulsion. He is an active contributor to the AIAA Space Systems Technical Committee, AIAA Journal for Spacecraft and Rockets and serves on the Georgia Institute of Technology and Embry-Riddle Aeronautical University Industry Advisory Boards.
 Dr. Anthony V. Piccolino is a new member of the adjunct faculty in the Department of Mathematics at PBCC-Palm Beach Gardens. He served for 16 years (1991-2007) as Associate Professor of Mathematics at Montclair State University in New Jersey where he taught mathematics and mathematics education courses at the undergraduate, graduate, and doctoral levels. He also served as co-Principal Investigator for a NSF-funded Systemic Initiative in Mathematics for the Professional Development of K-8 mathematics teachers in the Newark Public Schools. Prior to his tenure at Montclair State, he taught high school and middle school mathematics for 25 years in public schools throughout New York State and concurrently served as district supervisor for mathematics K-12.
He earned his B.S. in mathematics from Iona College, an M.S. in mathematics education from Yeshiva University, and his doctorate (Ed.D.) in mathematics education from Columbia University in New York. His area of research is in the History of Mathematics. Dr. Piccolino also earned a M. Ed. in education from Columbia University and a Prof. Diploma in Administration & Supervision from Fordham University.
Dr. Piccolino is co-author of a current high school mathematics textbook series Integrated Mathematics 1, 2, 3 published by McDougal Littell, co-author of a volume in the National Council of Teachers of Mathematics Navigations Series, Navigating Through Reasoning and Proof in Grades 9-12, co-author of Preparing for AP Statistics Examinations published by D & S Marketing, and has published over 30 articles in mathematics education journals on the history of mathematics and teaching mathematics in standards-based classrooms.
