Overview
Senior Investigator
Research Areas (IRP Lab Groups)
The Cutaneous Microbiome and Inflammation Section uses genomics to study the skin microbes in healthy individuals and patients with skin diseases and to expand our understanding of host-microbe interactions.
Our group studies the diversity and complexity of bacterial, fungal, and viral communities in healthy skin and in eczema from patients with atopic dermatitis and with primary immunodeficiencies. We integrate advanced genomic sequencing methods to investigate clinical samples and cultured isolates to more deeply understand these human microbial communities. Our work has demonstrated how the skin microbiome is patterned based on the location on the body surface (Grice et al., Science. 2009; Findley et al., Nature. 2013; Oh et al., Nature. 2014; Oh, Byrd et al., Cell. 2016), and can be distinguished in certain skin diseases and with specific immunodeficiencies (Kong et al., Genome Research. 2012; Byrd et al., Science Translational Medicine. 2017; Oh et al., Genome Research. 2013; Tirosh et al., Nature Medicine . 2018)
These studies have highlighted how the host shapes, and in turn may be shaped by, the skin microbiome. Our current efforts continue to explore these host-microbial interactions.
Research Focus
Our highly collaborative group studies the complexity of the microbial communities residing in and on the human body. We are focused on:

- Investigating the alterations in the human skin microbiome related to skin diseases, primary immunodeficiencies, and therapeutic interventions.
- Utilizing advances in microbiome and transcriptome sequencing to explore host-skin microbe interactions.
The translational team approach has been successful in integrating clinical medicine, genomics, microbiology, and immunology to study the role of staphylococci in atopic dermatitis as well as microbes in patients with immunodeficiencies. Our mission is to understand how microbes interact with the human host to elicit or ameliorate disease.
Ongoing Studies
The following studies are currently active. Further details are available following the links to the respective pages on the clinicaltrials.gov web site.
Studies of Dermatologic Diseases-Biospecimen Acquisition Protocol
ClinicalTrials.gov Identifier: NCT02471352 [12-AR-0144]
Skin diseases represent one of the most common medical problems in the United States, affecting 1 in 3 people at any given time. This study aims to procure biologic samples for exploratory cellular, molecular, genetic and genomic biological studies from subjects with dermatologic conditions, subjects at risk for developing dermatologic conditions and healthy volunteers in the support of NIH biomedical studies.
Effects of Antimicrobial Treatments on the Microbiome in Healthy Volunteers and Patients with Atopic Dermatitis
ClinicalTrials.gov Identifier: NCT01631617 [12-AR-0159]
The use of antibiotics has revolutionized medicine, yet the impact of antimicrobials on the human microbiome is incompletely understood. This study aims to characterize microbiome alterations in healthy adult volunteers and patients with atopic dermatitis after antimicrobial treatments.
The Acquisition of Blood and Skin Samples From Normal Volunteers to Support Research Activities on Dermatologic Diseases
ClinicalTrials.gov Identifier: NCT00001505 [96-AR-0097]
This study aims to collect blood, skin, or mucosal samples from healthy volunteers or patients with selected skin or systemic diseases as needed to support the research activities of our branch and other laboratories and branches.
