IRP’s Shannon Zenk Elected to the National Academy of Medicine

Nursing Research Leader Sheds Light on How Neighborhoods Influence Health

Dr. Shannon Zenk

When you think about public health, city planning might not be the first thing that comes to mind. Yet where we live — the quality of the buildings, the availability of places to walk and play safely, and the types of schools and stores in the neighborhood — can profoundly affect our health. This relationship has been emphasized by the COVID-19 pandemic, as close, stuffy living conditions, the need to take public transportation to essential jobs, and inequities in access to testing and vaccination sites all contributed to the larger reduction in life expectancy for Black and Latino Americans compared to Caucasians over the last two years.

Shannon N. Zenk, Ph.D., M.P.H., R.N., F.A.A.N., Director of the National Institute of Nursing Research (NINR), was elected to the National Academy of Medicine in 2021 for her research into how neighborhood characteristics affect the health of residents and contribute to the health disparities seen between communities with different racial and ethnic makeups and different levels of income.

IRP’s Carolina Barillas-Mury Elected to National Academy of Medicine

NIH Researcher Recognized for Important Insights Into Malaria Transmission

Dr. Carolina Barillas-Mury

In many parts of the world, the high-pitched buzz of a mosquito is a harbinger of more than an annoying itch — it’s a warning of possible malaria infection. Malaria, a disease spread by mosquitos that causes high fever and flu-like illness, is a serious risk for nearly half of the world’s population. According to the World Health Organization, there were 241 million cases of malaria and 627,000 deaths in 2020 alone. More than 95 percent of them occurred in Africa.

Efforts to combat malaria using measures like preventative treatments and environmental mitigation have helped to reduce infections and deaths over the past decade, but those improvements have recently plateaued, according to IRP Distinguished Investigator Carolina Barillas-Mury, M.D., Ph.D., section chief in the Laboratory of Malaria and Vector Research in the National Institute of Allergy and Infectious Diseases (NIAID).

IRP’s Heinz Feldmann Elected to National Academy of Medicine

Vaccine Research Facilitated Rapid Response to Ebola Outbreak

Dr. Heinz Feldmann

IRP Senior Investigator Heinz Feldmann, M.D., was elected to the National Academy of Medicine (NAM) last year for leading the development of the technology that resulted in the first Ebola vaccine approved by the US Food and Drug Administration (FDA) and used by the World Health Organization (WHO) to combat the deadly disease. Election to the NAM is considered one of the highest honors in the fields of health and medicine.

As chief of the Laboratory of Virology at the National Institute of Allergy and Infectious Diseases (NIAID), Dr. Feldmann’s work focuses on viruses like Ebola that cause hemorrhagic fever, a condition marked by fever, weakness, muscle pain, and sometimes bleeding. These highly contagious viruses require specialized laboratories and strict safety procedures to study.

IRP’s Cynthia Dunbar Elected to National Academy of Medicine

Studies of Blood Stem Cells Stimulate Pioneering Therapeutic Approaches

Dr. Cynthia Dunbar

The National Academy of Medicine (NAM), first established in 1970 by the National Academy of Sciences as the Institute of Medicine (IOM), is comprised of more than 2,000 elected members from around the world who provide scientific and policy guidance on important matters relating to human health. Election to the NAM is considered one of the highest honors in the fields of health and medicine and recognizes individuals who have not only made critical scientific discoveries but have also demonstrated a laudable commitment to public service.

IRP Distinguished Investigator Cynthia E. Dunbar, M.D., was elected to the NAM last year for her pioneering research into hematopoietic stem cells, the cells in bone marrow that develop into oxygen-carrying red blood cells, infection-fighting white blood cells, and clot-forming platelets. Her work has led to valuable insights into the production of those blood cells, called hematopoiesis, and its role in human health. Her discoveries have also resulted in new approaches to treat disease by improving stem cell functioning or manipulating stem cells with gene therapy.

IRP’s Peter Choyke Elected to National Academy of Medicine

New Imaging Approach Improves Care for Men at Risk of Prostate Cancer

Dr. Peter Choyke

The National Academy of Medicine (NAM), first established in 1970 by the National Academy of Sciences as the Institute of Medicine (IOM), is comprised of more than 2,000 elected members from around the world who provide scientific and policy guidance on important matters relating to human health. Election to the NAM is considered one of the highest honors in the fields of health and medicine and recognizes individuals who have not only made critical scientific discoveries but have also demonstrated a laudable commitment to public service.

IRP senior investigator Peter Choyke, M.D., was elected to the NAM last year for his pioneering advances in imaging technologies for prostate cancer, which have improved diagnosis and treatment. Dr. Choyke, who directs the Molecular Imaging Branch at the National Cancer Institute (NCI), harnessed artificial intelligence to superimpose images from magnetic resonance imaging (MRI) scans onto images taken in real time using ultrasound, thereby enhancing doctors’ ability to non-invasively examine prostate tumors. This allows doctors to be more precise with their biopsies, thereby lowering discomfort and the risk of nerve damage when they take samples of the tumor. Better yet, if the images show no signs of cancer, patients can skip the invasive biopsy procedure entirely and just continue regular monitoring and checkups.

IRP’s Julie Segre Elected to the National Academy of Medicine

NIH Researcher Recognized for Investigation into the Skin Microbiome

Dr. Julie Segre

The National Academy of Medicine (NAM), first established in 1970 by the National Academy of Sciences as the Institute of Medicine (IOM), is comprised of more than 2,000 elected members from around the world who provide scientific and policy guidance on important matters relating to human health. Election to the NAM is considered one of the highest honors in the fields of health and medicine that recognizes individuals who have not only made critical scientific discoveries but have also demonstrated a laudable commitment to public service.

IRP senior investigator Julie Segre, Ph.D., was one of four IRP researchers elected to the NAM in 2019. Dr. Segre leads the Translational and Functional Genomics Branch at the National Human Genome Research Institute (NHGRI), where she studies the way in which the skin forms a barrier between the body and the environment. In particular, her research uses genetic sequencing to understand the bacterial and fungal microbes that live on human skin.

IRP’s Andre Nussenzweig Elected to National Academy of Medicine

NIH Researcher Recognized for Investigation into Genomic Stability

Dr. Andre Nussenzweig

The National Academy of Medicine (NAM), first established in 1970 by the National Academy of Sciences as the Institute of Medicine (IOM), is comprised of more than 2,000 elected members from around the world who provide scientific and policy guidance on important matters relating to human health. Election to the NAM is considered one of the highest honors in the fields of health and medicine and recognizes individuals who have not only made critical scientific discoveries but have also demonstrated a laudable commitment to public service.

IRP senior investigator Andre Nussenzweig, Ph.D., was one of four IRP researchers recently elected to the NAM. Dr. Nussenzweig leads the Laboratory of Genome Integrity at the National Cancer Institute (NCI), where he studies how cells repair a form of DNA damage called a double strand break (DSB). This type of insult, which severs both strands of the double-stranded DNA molecule, is one of the most dangerous. If not repaired properly, DSBs can kill cells or cause DNA to rearrange in ways that are associated with cancer. Moreover, while DSBs can be caused by chemotherapy drugs and radiation, they can also happen by random chance during the course of normal cellular processes. Intriguingly, not all parts of the DNA molecule are equally susceptible to this form of damage.

IRP’s Luigi Notarangelo Elected to National Academy of Medicine

NIH Researcher Recognized for Insights into Genetic Immune System Diseases

Dr. Luigi Notarangelo

The National Academy of Medicine (NAM), first established in 1970 by the National Academy of Sciences as the Institute of Medicine (IOM), is comprised of more than 2,000 elected members from around the world who provide scientific and policy guidance on important matters relating to human health. Election to the NAM is considered one of the highest honors in the fields of health and medicine and recognizes individuals who have not only made critical scientific discoveries but have also demonstrated a laudable commitment to public service.

IRP senior investigator Luigi Notarangelo, M.D., was one of four IRP researchers recently elected to the NAM. As the head of the Immune Deficiency Genetics Section and the Laboratory of Clinical Immunology and Microbiology at the National Institute of Allergy and Infectious Diseases (NIAID), Dr. Notarangelo investigates the cellular and molecular roots of genetic conditions called primary immune deficiencies that compromise the immune system. These illnesses leave patients — many of whom are children — highly vulnerable to infections and can also lead to autoimmune problems caused when the immune system attacks the body’s own tissues. Some of Dr. Notarangelo’s patients have known genetic mutations, while for others the source of their disease remains a mystery.
