• Reproductive Physiology & Pathophysiology Group

Francesco DeMayo, Ph.D., is Chief of the Reproductive and Developmental Biology Laboratory, and leads the Pregnancy and Female Reproduction Group. He also holds a secondary appointment in the NIEHS Immunity, Inflammation, and Disease Laboratory.

The Pregnancy and Female Reproduction Group goal is to define the molecular mechanisms regulating normal reproductive tract and pulmonary function. The accomplishment of this will allow a better understanding how these tissues are impacted by the environment. We will be better able to determine how the endocrine disruptors impact the ability of the reproductive tract to initiate and maintain pregnancy. Also we will determine how these factors impact the development of reproductive diseases such as endometriosis and endometrial cancer. We will also be able to determine how environmental insults impact the progression and development of pulmonary diseases such as lung cancer.

Dr. Michael Fessler received his medical degree at Harvard Medical School in 1996, and followed this with internal medicine residency training at Massachusetts General Hospital and pulmonary/critical care medicine training at University of Colorado. While at University of Colorado as a physician scientist, Dr. Fessler developed expertise in research into the human immune system, focusing in particular on macrophages and neutrophils, white blood cells that protect the body from infection, but that can also cause damaging inflammation in the lungs and other organs. In 2006, Dr. Fessler moved to NIEHS to start his own laboratory, which conducts a wide range of basic (cell-based) and clinical (epidemiology, patient-based) studies that aim to identify mechanisms by which the immune system gets activated, and how we may intervene in its activation to treat or prevent lung diseases such as pneumonia, acute lung injury, and asthma.  As Acting Chief of the Immunity, Inflammation and Disease Laboratory at the NIEHS, he now oversees a department of research laboratories focused on the study of immune-mediated diseases.  In his own work, Dr. Fessler has identified variations in the DNA code that put patients at heightened risk of damaging inflammation, has identified a role for household dust bacteria in driving inflammation in healthy people, has discovered new ways by which high cholesterol causes inflammation, and has also identified new potential drugs for treating immune system overactivation.  His ongoing studies on immune cells collected at the NIEHS Clinical Research Unit, made possible by the generous participation of volunteer blood donors, ultimately aspire to advance our understanding and treatment of inflammatory diseases in humans.

Stavros Garantziotis, M.D. is passionate about finding cures for chronic lung disease like asthma, COPD and pulmonary fibrosis. He believes that if we can understand the mechanism of disease development for every individual patient, we can design intelligent and effective treatment with less side effects. Dr. Garantziotis obtained his medical degree at the Albert-Ludwigs-University in Germany. He trained in Internal Medicine at the Albert Einstein College of Medicine in New York and in Pulmonary and Critical Care Medicine at Duke University Medical Center, where he was a faculty member before joining NIEHS.

• Matrix Biology Group

The Fertility and Reproductive Health Group is led by Anne Marie Z. Jukic, Ph.D., who also works in the Reproductive and Developmental Biology Laboratory. Her work focuses on factors that affect or change reproductive function (e.g., ovulation and menstrual cycles), conception, implantation, placental development, and pregnancy outcomes. Given the financial and emotional burden of fertility problems and pregnancy loss, this research has broad and immediate public health relevance.

Frederick W. Miller, M.D., Ph.D. oversees researchers in his group as well as others in national and international consortia that evaluate and conduct a wide range of basic and clinical studies on adult and juvenile autoimmune diseases. His interests are broad and he wishes to understand what triggers these diseases and how to best assess, treat, cure and ultimately prevent them. He obtained his M.D. and Ph.D. from Case Western Reserve University, went on to medical residencies at Emory and Stanford, and then did rheumatology and immunology training at the NIH. His work in the field of autoimmune diseases spans over three decades and involves many aspects of the phenotypes, environmental risk factors, epidemiology, immunology, genetics, pathogenesis, evaluation and treatment of immune-mediated diseases. He has focused much of his work on autoimmune muscle diseases.

Joan P. Packenham, Ph.D., is founder of the NIEHS Women’s Health Awareness, Women’s Wellness Conference and Principal Investigator for the Women’s Environmental Health Across the Lifespan (WEHeAL) Program. She is a passionate and strong advocate for women’s health as it relates to discovering the root causes of environmental health disparities in underserved, understudied and underreported populations. Her goal is to empower women to promote wellness, improving their overall health and resiliency through disease prevention, control, and management. Her program aims to advance environmental public health and health equity by improving women’s access to health care as well as affecting environmental public health quality and policy.

Dr. Packenham graduated Magna Cum Laude with a B.S. from North Carolina Central University, and received a Ph.D. from the University of North Carolina at Chapel Hill, School of Medicine, Pathology Department. She completed her Post-Doctoral Fellowship at the National Institute of Environmental Health Sciences, Laboratory of Molecular Carcinogenesis. Dr. Packenham is currently the Director for the Office of Human Research Compliance, Clinical Research Branch.

Skand Shekhar, M.D., D.A.B.I.M., is a clinician investigator in endocrinology and reproduction with a special interest in studying the relationship between metabolism and reproductive disorders. As the deputy leader of the Reproductive Physiology and Pathophysiology group led by Janet E. Hall, M.D., M.S. at NIEHS, Shekhar cares for patients with metabolic and genetic disorders of reproductive function, including idiopathic hypogonadotropic hypogonadism (IHH), Kallmann syndrome, puberty disorders, menstrual disorders, and polycystic ovarian syndrome (PCOS). His research involves studying the interaction between lifestyle, sleep, diet, and the hypothalamic-pituitary gonadal axis in humans. With a keen interest in neuroendocrinology, he studies the interaction between stress (cortisol), thyroid, and reproductive axes. He is developing clinical trials to enhance our understanding of sleep, metabolism, and reproductive endocrinology interplays. Some of his published work in this field has studied rare neoplasms such as Cushing syndrome and Erdheim-Chester disease.
