Stefan Tullius, MD, PhD

  • Chief, Division of Transplant Surgery, Brigham and Women’s Hospital
  • Director, Transplant Surgery Research Laboratory, Brigham and Women’s Hospital
  • Professor of Surgery, Harvard Medical School

Training/Education: Dr. Tullius received his MD from the Johann-Wolfgang Goethe University in Frankfurt/Main, Germany, a PhD from the Charité in Berlin, Germany, and a (honorary) Master of Arts from Harvard University. While in medical school, he did a surgical rotation at Harvard Medical School, which brought him in contact with Dr. Nicholas Tilney, former Francis D. Moore Professor in Surgery, emeritus, and, at the time, Director of the Surgical Research Laboratory/HMS, and Chief of Renal Transplantation at Brigham and Women’s Hospital. After finishing his internship in Germany, he returned to BWH/HMS, where he was a research fellow in the Surgical Research Laboratory, pursuing his interest in transplant immunology. During that time, he contributed with internationally-recognized experimental data serving as the basis of the concept that organ quality and injury determine chronic allograft nephropathy and outcome after transplantation. He returned to Germany to complete his residency in general surgery, followed by a fellowship in visceral surgery, while at the same time, completed his PhD.

Research Interests: Dr. Tullius’ clinical interests focus on kidney/pancreas transplantation, the treatment of older transplant patients, individualized immunosuppression, and an optimized utilization of organs for transplantation including those from older donors. Dr. Tullius has also contributed with pioneering work in face, hand and uterus transplantation. His research laboratory has focused on the understanding of immunosenescence and organ age, obesity and alloimmunity, and the effects of organ quality on transplant outcome. His research on donor and recipient age has helped to pave the way for numerous clinical studies striving to reduce the consequences of organ damage either as donor, peri-operative, or short-term recipient treatment.

Neppl, Ronald L.

Ronald L. Neppl, PhD

  • Assistant Professor of Orthopedic Surgery, Brigham and Women’s Hospital, Harvard Medical School

Training/Education: Dr. Neppl received his B.S. and M.S. in Biomedical Engineering from Marquette University. He then worked in industry for a few years before returning to academia. He received his Ph.D. from the University of Virginia in Biophysics, where under the mentorship of Drs. Andrew and Avril Somlyo, he studied signal transduction in vascular smooth muscle. For his postdoctoral research, he then joined the laboratory of Dr. Da-Zhi Wang at Boston Children’s Hospital where he focused on studying the roles of microRNAs and novel proteins that modulate the activity of the RNA Induced Silencing Complex in cardiac and skeletal muscle. He then moved to the laboratory of Dr. Kenneth Walsh and focused on long non-coding RNAs that modulate skeletal muscle growth processes before joining the faculty in the Department of Orthopedic Surgery at Brigham and Women’s Hospital.

Research Interests: Our laboratory is focused on the molecular regulation of skeletal muscle homeostasis in health and disease. Our overarching goal is to understand how non-coding RNAs control the essential processes of myogenesis and hypertrophic growth, and how perturbations in these processes may lead to a disease state resulting in muscle atrophy. Using traditional biochemical and molecular biology techniques, in vivo and in vitro model systems, ChIP-seq, as well as next generation RNA sequencing, we seek to understand the molecular and biological roles these non-coding RNAs play in regulating the age-dependent changes in gene expression underlying the progressive loss of muscle mass and strength associated with advancing age.

Singh, Ranjan

Rajan Singh, PhD

  • Associate Professor of Medicine, Department of Obstetrics and Gynecology at David Geffen School of Medicine at UCLA and Division of Endocrinology and Metabolism at Charles R. Drew University of Medicine
  • Research Scientist, Brigham and Women’s Hospital

Training /Education: Dr. Singh received his M.S in Biochemistry from Kolkata University and PhD in Molecular Biology from Jadavpur University. He joined UCLA School of Medicine for his post-doctoral training in specific areas of hormonal regulation of cell metabolism and signal transduction pathways related to cell fate determination.

Research Interests: Dr. Singh has long standing interest and research experience in specific areas of androgen biology and aging research. For last 16 years of his independent career, Dr. Singh has been interested in delineating the molecular mechanism of androgen action on muscle and fat mass. His initial research work led to the identification of follistatin (Fst) as a novel target of androgen action via activation of Wnt/β-catenin signaling pathway, and subsequent identification of anabolic pathways that are differentially responsive to testosterone action in muscle and prostate tissues. His laboratory also identified a novel role of follistatin in regulating brown adipose metabolism and currently focused on investigating the cellular targets of follistatin responsible for the regulation of lipid and energy homeostasis, and determine the molecular mechanisms that participate in the pro-browning and anti-atherogenic properties of follistatin.
