He has developed a wide range of unique fluorescent latex particles and has authored several recent patents and publications on fluorescent latex and chemical modification of proteins.

Mohamed S. El-Aasser, Ph.D.

Dr. El-Aasser is the Iacocca Professor of Engineering and Applied Sciences and the Director of the Emulsion Polymers Institute at Lehigh University, Bethlehem, PA, U.S.A. He has over 25 years of research work in emulsion polymerization and polymer colloids, which are documented in more than 200 technical publications, three edited books, and 8 U.S. patents. He is a major consultant to industry in all aspects of emulsion polymerization and latex technology, which includes emulsion polymerization and emulsification processes, surface and colloidal properties of latexes and their film formation.

Eileen Gorman, Ph.D.

Dr. Gorman, originally from El Paso, Texas, received her B.S. in Chemistry from the University of Texas at El Paso and her Ph.D. from New Mexico State University. During the past 15 years, she has lived in the mid-Atlantic area and has worked as an integral member of the DuPont Diagnostics health care / medical products organization in a variety of capacities, from research and product technical marketing to management of DuPont Medical Products' intellectual property portfolio as a Patent Specialist. She was responsible for initiating and maintaining a long term research relationship with Professor Christopher Price, which resulted in commercialization of five latex particle based immunoassays and proven feasibility of several others. She has received numerous awards and has authored over 40 chapters, papers and corporate reports.

Paul R. Hemmes, Ph.D.

Dr. Hemmes has held senior academic positions at Rutgers University and has also worked in both research and manufacturing companies in the diagnostics industry. He has published 60 papers and 8 patents. He has been involved for the past 12 years with the problems associated with technology transfer between research and manufacturing. Dr. Hemmes is Vice President of Operations for Abaxis, Inc. Sunnyvale, California.

Jack Kettman, Ph. D.

Dr. Kettman is Professor of Microbiology at the University of Texas Southwestern Medical Center at Dallas, Texas and Director of the Dallas Cell Analysis Facility. For the past 20 years, he has studied clonal development and lymphocyte activation, especially analysis of gene expression during T-cell activation. More recently Dr. Kettman has pursued innovative uses of microsphere and flow cytometric technology to develop multiplex analytical approaches to diagnostic assays. He has authored over 200 publications.

Robert J. Knox, Ph.D.

Dr. Knox is a biochemist with substantial research experience in the electrophoretic characterization of biological particle surfaces. He has applied analytical particle electrophoretic methods to latex processing problems in both the R & D and manufacturing settings, ranging from characterization of latex starting materials and monitoring steps in latex coating to troubleshooting various latex processing problems. Dr. Knox is Vice President of Emerald Diagnostics, Inc. in Eugene, Oregon.

Christopher Price, Ph. D.

Professor Price is Head of Clinical Biochemistry at the St. Bartholomew's and Royal London School of Medicine and Dentistry and Clinical Director at the Royal Hospitals NHS Trust, London, UK. He has worked in the field of quantitative latex immunoassays for several years studying both the basic chemistry of the antigen antibody reaction and its application in clinical practice. He has published over 200 scientific papers and reviews and is an editor of the successful reference text "Principles and Practice in Immunoassay".

James L. Sackrison

Mr. Sackrison is an immunochemist with over 10 years experience in diagnostic assay development. He is well known for innovative conjugation and assay design and has developed numerous commercial immunoassays which have become leading technologies. As the president of Lakeland Biomedical, Inc., Mr. Sackrison consults with a number of prominent diagnostic companies in the development of esoteric immunoassays.

Geoffrey V.F. Seaman, Ph.D.

Dr. Seaman has held senior academic and industrial positions in production, development and marketing of latexes, latex products, and biomedical devices. He has more than 30 years experience in the surface chemical, biochemical and biophysical sciences. He is the author of more than 200 publications and 3 books. Dr. Seaman is currently President of Emerald Diagnostics, Inc.
