Bruce D. Weintraub, MD

President
Chief Operating Officer and Chief Scientific Officer

Dr. Weintraub has more than 30 years experience in a biomedical research career that has focused on molecular, cellular, clinical and therapeutic aspects of glycoprotein hormones, related growth factors, thyroid hormone and their receptors. He is the author of over 300 scientific papers, reviews and book chapters. In addition has several issued and pending patents related to the cloning of the human TSH beta subunit, development of recombinant TSH, and development of superactive analogs of TSH, gonadotropins and related cystine knot growth factors. He is well known for his basic science work related to pituitary and recombinant TSH synthesis, glycosylation and action, affinity chromatography as well as clinical aspects of syndromes of inappropriate TSH secretion. In addition he was among the first to recognize and define the clinical and molecular aspects of thyroid hormone resistance, TSH- producing pituitary tumors and ectopic production of placental hormones and free subunits by various tumors. He is particularly recognized for his role as coinventor, codeveloper and a leading investigator in the international clinical trials of recombinant TSH, approved by the FDA in 1998 for the diagnosis of thyroid cancer, which has revolutionized the approach world -wide to that disease.

Dr. Weintraub obtained his BA from Princeton University magna cum laude where he was elected to Phi Beta Kappa and his MD from Harvard University cum laude where he was elected to Alpha Omega Alpha. His postdoctoral clinical and basic science training were at Harvard and the National Insitutes of Health and he later served as Assistant Professor at Harvard. In 1972 he became the first Director of the NIH Endocrinology Training Program and later Chief of its Molecular and Cellular Endocrinology Branch, positions he held until 1995. In both these positions he helped train a generation of leading international academic and clinical endocrinologists. From 1996- 2001 he was Professor of Medicine at the University of Maryland at Baltimore, Chief of the Laboratory of Molecular Endocrinology of the Institute of Human Virology of the University of Maryland Biotechnology Institute and Director of the Thyroid Cancer Program of the Greenebaum Cancer Center. He has received numerous international awards and lectureships, is a member of many scientific research organizations, served on several journal editorial boards as well as on several advisory committees to NIH and various universities. He has also served on the Council of the Endocrine Society and the American Thyroid Association as well as President of the Maryland Endocrine Society.

 

 

Mariusz W. Szkudlinski, MD, PhD
Vice President for Research and Development

Dr. Szkudlinski has more than twenty years of experience in biomedical research. He is an author or co-author of more than 70 scientific papers, reviews, book chapters, patents and patent applications. His work includes a landmark paper entitled "Engineering human glycoprotein hormone superactive analogs" that has been recognized as "the advent of super hormone drugs" and an important achievement in protein engineering (Analysis Research News, Nature Biotechnology 14, 1224, 1996; Molecular Biology and Biotechnology, 4th Edition, The Royal Society of Chemistry, London 2000). In addition to his design of the first superactive analogs of glycoprotein hormones and VEGF, Dr. Szkudlinski contributed to better understanding of changes in the bioactivity of glycoprotein hormones during evolution and the development of novel strategies in the design of therapeutically useful cystine-knot growth factor superactive analogs. His previous work also includes studies on prostaglandins, local renin-angiotensin system, production and characterization of recombinant TSH isoforms, development of various bioassays as well as elucidation of the role of carbohydrate chains in TSH activity, metabolic clearance and organ distribution. Dr. Szkudlinski and his colleagues have identified novel domains in TSH and gonadotropins important in hormone-receptor interaction, designed long-acting analogs based on site-specific pegylation, glycosylation or subunit linking,, and more recently provided new important insights into the mechanism of hormone dependent and independent receptor activation.

Dr. Szkudlinski obtained his M.D. and Ph.D. degrees from the University of Lodz in Poland. His postdoctoral training included the Institute of Hormone and Fertility Research in Hamburg (Germany) and the National Institutes of Health in Bethesda. Prior to co-founding Trophogen, Inc., Dr. Szkudlinski was an Assistant Professor and Chief of Protein Engineering Section in the Laboratory of Molecular Endocrinology in the University of Maryland. In that capacity, he was responsible for several structure-function and protein engineering projects within the Laboratory of Molecular Endocrinology and the Division of Basic Science of the Institute of Human Virology (UMBI). He has received numerous awards for excellence in research, presented his work at many national and international meetings, lectured at various universities, including Harvard Reproductive Science Center. He has trained numerous students and postdoctoral fellows. He serves as a reviewer in several leading journals and was invited to several national scientific panels. He is currently a member of the American Thyroid Association Research Committee and several other biomedical organizations including Endocrine Society and American Society for Biochemistry and Molecular Biology.

Valerie Fremont, PhD
Group Leader

Safety Officer


Dr. Fremont obtained her Ph.D. degree in Biochemistry/Neurosciences from the University of Provence in France where her work was awarded the "Thesis of the Year 1997 Prize." During her post-doctoral training at Temple University in Philadelphia she contributed to a better understanding of the structure-function relationships of scorpion toxins with ionic channels through electrostatic interactions. She then joined Dr. Weintraub and Dr. Szkudlinski at the Institute of Human Virology, University of Maryland, Baltimore and contributed to the elucidation of the mechanism of activation of the TSH receptor. In July 2001 she followed the two co-founders to Trophogen. Her work focuses on studying the structural and molecular aspects of ligand-receptor interactions to help design new mutants with different specificities and/or affinities towards the various subtypes of a receptor family.

 

 

Vladimir Wolf, PhD
Senior Research Scientist

Information Technology Officer

Dr. Wolf obtained his Ph.D. degree in Molecular biology from the University of Bern in Switzerland where his work was awarded by the travel grant to present at an AACR meeting in 1997. His doctoral thesis was focused on early events in apoptosis of mammary epithelia. The malfunction of which often leads to cancer development. The gene he helped to discover and analyze turned out to be an important inhibitor of Wnt signaling pathway. This pathway is important in early embryonic development as a tissue polarity and cell fate determining factor, as a survival factor and differentiation blocker in blood circulating stem cells, it is involved in angiogenesis and vascularisation, arthritis, etc. During his post-doctoral training at National Cancer Institute he contributed to a better understanding of the biochemistry of inhibition of Wnt/Frizzled receptor binding by secreted Frizzled Related Proteins. Subsequent to his postdoc training, Dr. Wolf continued working as a FTE research fellow in the same lab for additional 2 years. After he left NCI and shortly utilized his experiences in studying ligand/receptor interactions in research of dopamine/dopamine transporter interactions in the Laboratory of Neurochemistry at Georgetown University.

In October 2004, Dr. Wolf joined Trophogen.
