His clinical practice also focuses on kidney stone prevention and minimally invasive and surgical treatments for kidney stones. He is an Assistant Editor of the Journal of Urology and an Editor of the Journal of Endourology Case Reports.

Brian attended Harvard College and the University of Michigan Medical School. He completed urology residency training at Massachusetts General Hospital and a fellowship in endourology and urinary stone disease at the University of California, San Francisco.

David S. Goldfarb, MD, FACP, FASN, FNKF, brings over thirty years of expertise in nephrology to Allena as a scientific advisor. David is currently a professor of Medicine and Physiology at NYU School of Medicine, Clinical Chief of Nephrology at NYU, Chief of Nephrology at the NY VAMC and co-director of the Kidney Stone Prevention Program at NYU Langone Medical center. David serves as the principal investigator of the cystinuria component of the Rare Kidney Stone Consortium, and as a member of the board of directors of the International Cystinuria Foundation, the medical advisory board of the National Kidney Foundation of Greater New York, and of the Oxalosis and Hyperoxaluria Foundation. David is the former President of the New York Society of Nephrology and of the ROCK Society (Research on Calculus Kinetics). He sits on the editorial boards of renowned journals including Kidney International, Urolithiasis, and Current Opinion in Nephrology and Hypertension, among others. In 2014 David received the “Stone Crusher of the Year” award in 2014 from the Oxalosis and Hyperoxaluria Foundation, and in 2016 he was named “Nephrologist of the Year” by the American Kidney Fund. On a personal note, he has had three calcium oxalate stones, an experience which gives him an acute understanding of the patients with whom he works everyday.

David graduated from Yale College and Yale School of Medicine. He completed his residency training in internal medicine and his nephrology training at NYU/New York VA.

Felix Knauf is a Professor of Nephrology at the Charité University Hospital Berlin, Germany, and an Assistant Professor Adjunct at Yale University. His research focuses on epithelial oxalate handling and the role of oxalate in chronic kidney disease. Felix studied medicine at the University Freiburg and Berlin.

Felix completed his doctoral thesis in the Department of Physiology and Internal Medicine at Yale University. He completed his medical training in Internal Medicine and Nephrology at Yale, and joined the faculty in 2011.

Craig B. Langman is the Isaac A. Abt, MD, Professor of Kidney Diseases, and Tenured Professor of Pediatrics at the Feinberg School of Medicine, Northwestern University, Head of Kidney Diseases at the Ann and Robert H. Lurie Children’s Hospital of Chicago, and director of the two Davita Children’s Dialysis Centers in Chicago. His funded research focuses on the basic and clinical expression of inherited or acquired disorders of calcium, phosphorus, vitamin D, and FGF23 metabolism, mechansims of cardiovascular diseases in children with obesity or chronic kidney disease, the proteomics of inherited stone disease, inherited genetic diseases (cystinosis, oxalosis, kidney stones, atypical HUS, hypophosphatasia), and the rehabilitation of patients around the world with chronic kidney disease.

Craig received his MD from Hahnemann University. He has published more than 275 articles, reviews and chapters in his discipline.

Orson W. Moe, MD, received his medical degree from the University of Toronto and is currently Professor of Internal Medicine and Physiology at the University of Texas Southwestern Medical Center. He is the Director of the Charles and Jane Pak Center of Mineral Metabolism and Clinical Research and Chief of the Nephrology Division at Southwestern. Orson is the holder of the Charles and Jane Pak Distinguished Chair in Mineral Metabolism Research and the Donald Seldin Professorship in Clinical Investigation. Orson conducts both basic science and patient-oriented research on renal physiology and metabolism as well as epithelial biology, striving to cross from the level of the whole patient to animal and cell culture models, and down to single molecules. He has edited Current Opinion in Nephrology and Hypertension, and the textbook, Seldin and Giebiesch’s The Kidney: Physiology and Pathophysiology. He also serves on the editorial board of the American Journal of Physiology, Journal of American Society of Nephrology, Clinical and Experimental Nephrology, and Journal of Nephrology. He is currently a member of the American Society of Clinical Research, American Association of Physicians, American Society of Nephrology, and American Physiologic Society.

Orson received his MD from the University of Toronto.

David Bruce Mount, MD brings a deep knowledge of nephrology and investigative research to the Allena team as scientific advisor. David is currently Assistant Professor of Medicine at Harvard Medical School and Associate Chief of the Renal Division at Brigham and Women’s Hospital. David has a longstanding interest in the molecular physiology of anion transporters, with significant publications in Nature Genetics, the Journal of Biological Chemistry, and other major journals. He currently has an NIH-funded research effort on the functional genomics of urate transport, working on the roles of insulin, IGF-1, angiotensin-II, and urate-associated genes in the regulation of GLUT9 and other urate transporters. Clinically, he has been repeatedly named a “Top Doc” in Nephrology by Boston Magazine, with expertise in glomerular disorders, fluid and electrolyte disorders, and acute kidney injury. He also has highly specific expertise in the treatment of gout in chronic kidney disease. He is a much sought-after clinical educator in Nephrology, with multiple chapters in UpToDate, Harrison’s Principles of Internal Medicine, and other major textbooks.

David is an MD graduate at the University of Toronto. He completed his Medical Residency at Toronto General Hospital, followed by a Renal Fellowship at Brigham and Women’s Hospital, where he trained in Steve Herbert’s laboratory.

Gregory Tasian is an Assistant Professor of Urology and Epidemiology and a Senior Scholar in the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania Perelman School of Medicine. Gregory is also an attending urologist and core faculty member of the Center for Pediatric Clinical Effectiveness at The Children’s Hospital of Philadelphia (CHOP). As Co-Director of the CHOP Kidney Stone Center, Gregory’s clinical practice focuses on the medical and surgical treatment of children with kidney stones. He has published and lectured extensively, and he is a nationally recognized expert on the determinants of nephrolithiasis in children and interventions to decrease the risk of stone recurrence among adolescents.

A graduate of Baylor College of Medicine, Oxford University, and the University of Pennsylvania, Gregory completed a Urology residency at the University of California, San Francisco and a pediatric urology fellowship at CHOP.
