Research Topics
Dr. Nihal Altan-Bonnet heads the Laboratory of Host-Pathogen Dynamics at the National Institutes of Health in the USA. Her lab is comprised of a multidisciplinary team of cell biologists, virologists, environmental engineers, and computational biologists who apply their talents to understand how viruses transmit themselves effectively among hosts and establish successful infections. Dr. Altan-Bonnet and her team have made groundbreaking discoveries that include:
- Discovering that PI4P lipids panvirally critical for infection by RNA viruses (Hsu et al., Cell 2010)
- Discovering a novel highly virulent viral infectious unit where viruses are transmitted en bloc inside extracellular vesicles (Chen et al., Cell 2015; Santiana et al., Cell Host and Microbe 2018).
- Discovering SARS-CoV2 and other coronaviruses use the unusual lysosomal exocytotic pathway to exit cells, disrupt antigen presentation and evade immune defenses (Ghosh et al., Cell 2020).
- Discovering that enteric viruses such as norovirus, rotavirus and astrovirus also replicate in salivary glands and transmit through saliva (Ghosh et al., Nature 2022)
Biography
Dr. Nihal Altan-Bonnet received her B.A. in biology and chemistry from Hunter College, New York in 1992 and her Ph.D. in cell biology from The Rockefeller University in 1998. She then conducted postdoctoral research with Dr. Jennifer Lippincott-Schwartz at the National Institute of Child Health and Development at the NIH from 1999 to 2005 before receiving a faculty position in the department of biological sciences at Rutgers University. In 2013, Dr. Altan-Bonnet returned to the NIH as an Earl Stadtman Investigator, becoming head of the Laboratory of Host-Pathogen Dynamics at the NHLBI and was promoted to tenured Senior investigator in 2017. Dr. Altan-Bonnet has been recognized several times for her outstanding research, receiving the Presidential Early Career Award in Science and Engineering (PECASE) in 2012, being named the John J. Holland lecturer at the American Society of Virology in 2017, and receiving the Norman Salzman Mentor Award in Virology in 2018. Dr. Altan-Bonnet was also named a Kavli Fellow and Scialog Fellow from 2013-2016. She is an Associate editor at the Molecular Biology of the Cell and is a member of the American Societies for Virology, Microbiology, and Cell Biology.
