She received her Bachelor's Degree in Biochemistry & Business Management from the University of Michigan and her Ph.D. in Biochemistry from the Department of Chemistry at Wayne State University specializing in DNA-protein cross-links. Her research involved the investigation and discovery of 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-Department of Physiology studying peripheral vascular occlusive disorders. She was a post-doctoral research fellow at the National Institutes of Health in the National Institute on Aging, where she investigated the mechanisms of rare premature aging disorders, primarily that of Werner's Syndrome.

Dr. Gorgevska has and continues to be involved with the development and expansion of biotechnology curricula to meet the needs of the emerging bioscience community. In 2009, she was honored with the Distinguished New Faculty Award at the 20th International Conference on College Teaching and Learning. She was a research mentor with the U.S. Army eCybermission program. She also served as the Curriculum Development Manager for the Employ Florida Banner Center for Life Sciences at Palm Beach State College, which was a 3-year 1.2 million dollar grant-funded strategic plan to modernize Florida's workforce in order to meet the workforce needs of the state. Dr. Gorgevska was the Principal Investigator for a National Science Foundation Advanced Training Education (NSF-ATE) grant, a 2-year $200,000 funded project that helped to increase enrollment, retention and success of biotechnology students within the program and into their careers. She worked with the Quantum Foundation Science Path Institute, which was a 3-year grant initiative to provide professional development training and updated curriculum for high school science teachers. She helps represent the PBSC Biotechnology Program as part of the LSSF, Life Sciences South Florida consortium, including serving on the student research symposium planning committee. She worked with the PBSC Math & Science Institute for 10 years, which was a summer honors program for dual enrolled and PBSC students. She is currently involved with the PBSC STEM Collegiate High School program. She is also a chemistry instructor with the AAUW Tech Trek summer program for 8th grade girls. She strives to provide high quality instruction by recruiting well-qualified adjunct instructors from industry and research. She provides career mentorship to students in addition to seeking new, relevant curriculum to help train a well-qualified workforce.

Dr. Becky A. Mercer is the Associate Dean of Academic Affairs, Palm Beach Gardens Campus and Adjunct Biotechnology Professor. Dr. Mercer earned her Ph.D. in Metabolic Sciences from the Department of Molecular Medicine at Columbia University in New York City.  During her graduate studies, she investigated cellular and genetic mechanisms involved in pulmonary emphysema and lung cancer, using mice, rabbits and guinea pigs, cell-based assays, and human lung biopsies.  Her work has been published extensively in peer-reviewed scientific journals and presented at international conferences.

Dr. Mercer began her science career as an undergraduate research assistant in Los Angeles at the University of Southern California’s Neurosciences Department and in the USC Dental School, investigating mechanisms of bone remodeling, osteoporosis, and cell development, publishing her first scientific manuscript in 1998.  Dr. Mercer served as a Senior Research Associate at Telios Pharmaceutics in San Diego, CA and as an Editor at the Journal of Clinical Investigation. After grad school, Dr. Mercer came to Florida to pursue post-doctoral training in the Department of Cancer Biology at Scripps Florida, where she was a part of a research team that identified a novel protein involved in cAMP-activated gene transcription.  After completing and publishing her postdoctoral work, Dr. Mercer was invited to join Scripps’ High Throughput Screening group as the Associate Scientific Project Manager where she assisted in securing projects to identify novel chemical probes as part of an $80 million grant from the National Institutes of Health (NIH).  Dr. Mercer holds a Certificate in Project Management from Florida Atlantic University and is a Director at Ocean Ridge Biosciences, a Palm Beach Gardens-based genomics company.  Dr. Mercer is an active member of several Palm Beach County economic and education committees, non-profits, and school advisory boards, and has developed teacher professional development, high school internships, and community STEM programs.

Dr.Sirtana Yasui
 Adjunt Biotechnology Professor 


Dr. Yasui’s passion is making chemistry a more enjoyable and manageable subject to students, rather than a cringe-worthy requirement. She has combined experiences in research at federal and academic laboratories - with over 25 papers published; along with teaching at college and high school levels. These experiences have made her realize how crucial a chemistry background is for students, and she strives to help them develop an appreciation, and ultimately a passion for the subject. While she has a core method of teaching chemistry, it is adjusted every semester based of the background of each student.

Dr. Yasui graduated from Ohio University with Ph.D. in physical organic chemistry and worked at the Forensic Chemistry Center, US Food and Drug Administration (FDA); University of Illinois (UIC) and Texas Christian University (TCU). Her research focused on food and drug tampering and/or poison cases; structures of proteins and small chiral molecules; and enzyme kinetics of heme porphyrins.

Edison Mejia
Biotechnology Lab Specialist

edison Edison Mejia has a Bachelor of Science in Medical Technology from the University of Antioquia- Colombia. His passion for science started 20 years ago while studying diagnosis, infection and epidemiology of Trypanosomiasis.

Edison later joined Stony Brook University in Long Island, NY where he worked for 12 years as a Research Specialist in the Molecular Genetic and Microbiology Department. During his time there, he worked with tissue culture and performed experiments with a chimera of Hepatitis C virus. He also conducted experiments on Yersinia bacterium and its interaction with eukaryotic cells. Edison then moved on to the Pharmacological Sciences Department where he participated in projects involving molecular cloning, protein expression and purification, structural and biochemical characterization of different mitochondrial proteins and X-Ray Crystallography.
