Board of Directors

Stephen J. Forman, M.D., is an internationally recognized expert in hematologic malignancies and bone marrow transplantation and is a leader in preclinical and clinical cancer research. He is co-editor of Thomas’ Hematopoietic Cell Transplantation, a definitive textbook for clinicians, scientists and health care professionals. Dr. Forman is the Francis and Kathleen McNamara Distinguished Chair in Hematology and Hematopoietic Cell Transplantation at the City of Hope Comprehensive Cancer Center, a position he has held since 1987.

In nearly 40 years at City of Hope, Dr. Forman has been instrumental in advancing the survival rates for patients suffering from cancers of the blood and immune system such as leukemia, lymphoma and myeloma.

As Director of the T Cell Immunotherapy Research Laboratory, his current research is focused on cancer immunotherapy — using the body’s own immune system to attack cancer. Pharmacological enhancement of patients’ immune responses to their cancers is of special interest to Lixte as the enzyme target of its lead clinical compound, LB-100, has been reported recently to be critical to immune function. Much of his current work centers on T cells and their cancer-fighting potential.


Winson Ho, M.D. is Assistant Professor, Department of Neurosurgery at the University of Texas at Austin Dell Medical School. After receiving his MD from Yale University School of Medicine, he had four years of training in Neurosurgery at the University of Virginia, Charlottesville, VA and completed a pediatric neurosurgery fellowship at the University of Utah School of Medicine. Prior to his final year as chief resident at UVA, Dr. Ho spent three years doing molecular pharmacologic research on methods to enhance the efficacy of cancer therapy as a Clinical and Research Fellow in the Surgical Neurology Branch, National Institute of Neurological Disorders and Stroke, NIH. His research includes several studies of Lixte’s lead clinical compound, the protein phosphatase 2A inhibitor LB-100, including the demonstration that LB-100 potentiates the effectiveness of the immune checkpoint blocker, PD-1, in several preclinical models, results that were recently published in Nature Communications.


John S. Kovach, M.D. founded Lixte and has been its sole administrative officer. Dr. Kovach has directed leading National Cancer Institute–designated Comprehensive Cancer Centers at Mayo Clinic, Rochester, Minnesota and City of Hope National Medical Center, Los Angeles, California. He has extensive experience in medical oncology, anti-cancer drug pharmacology, and in applied medical research, particularly, the early evaluation of new anti-cancer drugs and the development and management of multi-disciplinary highly productive cancer research teams. Dr. Kovach, in consultation with Lixte’s advisors and board, is responsible for the selection and prioritization of the scientific directions and goals of Lixte.


Philip F. Palmedo, PhD is a physicist, entrepreneur, and corporate manager. He founded and served as Chairman of the International Resources Group (IRG), an international consultancy in energy, natural resources and economic development. IRG was bought by L3 Communications in 2008. Dr. Palmedo designed and was the first President of the Long Island Research Institute formed by Brookhaven National Laboratory, Cold Spring Harbor Laboratory, and Stony Brook University to facilitate the commercialization of technologies. In 1988 Dr. Palmedo joined in the formation of Kepler Financial Management, Ltd., a quantitative financial research and trading company. He was President and Managing Director until 1991 when Renaissance Technologies Corporation acquired the company.

Dr. Palmedo served on the boards of Asset Management Advisors, the Teton Trust Company, EHR Investments and C-Quest Capital. He also served on the Board of Trustees of Williams College and of the Stony Brook (University) Foundation where he chaired the Foundation’s Investment Committee.
