Junqin Bai

Junqin Bai, PhD, serves as a Research Assistant Professor in the Department of Otolaryngology - Head and Neck Surgery at Northwestern University's Feinberg School of Medicine, where she conducts translational research on chronic inflammatory sinus diseases with a focus on immunological mechanisms.

Education:

• PhD: University of Illinois at Chicago (2018)

Her research integrates molecular immunology and clinical otolaryngology to investigate cytokine networks (particularly thymic stromal lymphopoietin and IL-4 receptor pathways) and immune cell functions in chronic rhinosinusitis. She employs advanced methodologies including single-cell RNA sequencing to characterize cellular heterogeneity in nasal polyps, aiming to identify novel therapeutic targets for biologic treatments and surgical interventions.

Analysis of her 2025 publications reveals a cohesive research trajectory centered on translational immunology in upper airway inflammation, with recurring themes in biologic therapy mechanisms (e.g., tezepelumab), ectopic lymphoid tissue formation, neutrophil-mediated inflammation, and long-term surgical outcomes assessment in CRS patients.

Scientific Awards:

• No awards documented in provided institutional profile

Dr. Bai actively collaborates with Northwestern's multidisciplinary CRS research team including Dr. Atsushi Kato and Dr. Bruce K. Tan, contributing to NIH-funded studies on inflammatory pathways. While specific grant details are absent from the profile, her publication record in top-tier journals indicates substantial involvement in externally funded research projects. No formal advisees are listed in available records.

She operates within Northwestern's integrated CRS research ecosystem, collaborating closely with the Division of Allergy and Immunology and the Sinus Center to advance understanding of inflammatory mechanisms and treatment responses in chronic rhinosinusitis.
