Dr. Matthew Lee is the President/CEO at CytoTest Inc. He has over 20 years of experience in biotechnology and venture capital investment. He joined CytoTest in 2020 at the invitation of Chairman Vinsen Hsiao, a well-recognized business leader, to restructure the company, strengthen the new business focus on genetics, and transform CytoTest into a modern genetics company in the era of personalized medicine. 

Dr. Lee graduated from Virginia Tech with a B.S. in Biochemistry and Nutrition and then obtained his doctoral studies from Medical College of Virginia studying neural regeneration of the peripheral nervous system (PNS). He then conducted post-doctoral research on the central nervous system (CNS) regeneration and stem cell identification at the Brain Research Institute of UCLA.. 

Dr. Lee returned to Taiwan in 2000 to join the Center for Drug Evaluation in the biologics section for two years. He then moved into the biotech/biopharma venture capital space, joining investment companies including Cheng-Xin VC and Taian Technologies VC, where he focused primarily on new drug development and stem cell-related investments.. 

After six years in venture capital, Dr. Lee was invited to join the Medical Affairs Team at Bristol-Myers Squibb, where he participated in late-phase new oncology drug developments and their eventual launch in Asia Pacific (Singapore, Taiwan and Hong Kong). He later ventured into biotech start-ups, helping to grow a couple of firms in Taiwan that went on to achieve IPOs on TASDAQ, including OBI Pharma (TPEX, 4174) and CrownBio (TPEX, 6554). He also assisted several other biotech companies in Asia in different capacities; many of them went on to list publicly or undergo successful mergers.

He has extensive hands-on experience with, and documented record of achievements in, target and marker discovery, assay development, high-throughput screening, signal transduction and pathway delineation, lead optimization and development, and proven expertise in solving complex questions in molecular and cell biology, particularly as they relate to disease mechanism and drug discovery. 

Having served as a research manager and senior investigator in both academic and corporate settings, Dr. Reinhard Ebner has extensive scientific, technical and strategy experience, combined with a broad knowledge of modern biology and the biomedical and biotechnology industry, with a recent focus in contemporary oncology, translational medicine and molecular diagnostics.
He received his undergraduate degree in Biology from the University of Regensburg and his doctorate in Microbiology and Genetics from the University of Osnabrück, Germany, where he then served on the faculty of the Genetics department.
In 1989, Dr. Ebner was awarded a research fellowship to work as a visiting scientific specialist at Genentech, Inc. in San Francisco. There, he identified and cloned the long elusive first type I TGF-ß receptor. He was first to show TGFß-induced epithelial-mesenchymal-transitions (EMTs) in cells in culture and, in the years following, made a series of substantial contributions to the fields of cytokine biology, receptor-ligand interactions and intracellular trafficking, cell differentiation, early development and tissue repair, first at Genentech and then at the University of California, San Francisco and at Stanford University Medical School.
After moving to Human Genome Sciences in 1995, Dr. Ebner became one of the most productive novel gene finders there and the inventor of all the HGS targets now in clinical trials and discovered many other important proteins around which HGS established pre-clinical and clinical development programs, including such molecules as DR4, the first and long sought after receptor for the cytotoxic ligand TRAIL, as well as LIGHT, IL-17B and its receptor, BlyS and TR6. In 2000, he joined Avalon Pharmaceuticals – hired as the first scientist following the company founders, where he was instrumental in the initiation of intramural and external research programs and contributed to corporate and scientific infrastructure development, working predominantly in the fields of chemical genomics, cancer research, data mining and HTS assay development. He also coordinated the company’s therapeutic antibody target discovery alliances and has a long-standing interest in alternative and novel drug discovery paradigms and development strategies.
Dr. Ebner is a frequently invited plenary speaker at national and international conferences and member of several scientific advisory panels and has served on state and national study sections. He has authored nearly 100 original research publications, with several thousand citations by others. He is a recipient of grant and manuscript peer review service awards and society memberships, an ad hoc reviewer and editor for scientific journals, has over 50 issued US patents and is the primary inventor on more than 800 patent applications world wide. Several of his discoveries have led to new therapeutics now in the clinic or on the market.
Dr. Ebner has been involved with the National Cancer Institute for many years, and is currently a research adviser in its cancer genomics section. He also is a consultant to various biotech companies, and serves as the CSO of CytoTest Inc., a provider of innovative molecular diagnostic solutions.
