Job description

Postdoctoral Position: Red Blood Cell Immunobiology

Location: Perelman School of Medicine at the University of Pennsylvania

Open Date: Jan 05, 2026

Deadline: Jan 05, 2026

Overview

The Mangalmurti Laboratory invites applications for a postdoctoral position examining red blood cells (RBCs) as previously unrecognized regulators of innate immunity. The laboratory focuses on how RBCs participate in nucleic acid sensing, immune homeostasis, and inflammatory disease, with a long‑term goal of translating fundamental red blood cell immune functions into clinically relevant applications. The lab made the seminal discovery that red blood cells express the nucleic acid‑sensing receptor TLR9 and actively sequester cell‑free DNA, redefining RBCs as active participants in innate immune regulation. Ongoing work integrates mechanistic in vitro systems, organ‑on‑a‑chip platforms, clinical specimens from critically ill patients, and erythroid‑specific PRR‑deficient mouse models to interrogate how RBC immune sensing shapes host responses during inflammation and infection. Two NIH‑funded postdoctoral projects are available. One focuses on extracellular RNA sensing by RBCs and its impact on systemic immune responses during sepsis. The second examines how RBC‑TLR9‑mediated DNA sensing and delivery contributes to host heterogeneity in sepsis and pneumonia.

Training Environment and Mentorship

Postdoctoral fellows receive close mentorship with an emphasis on developing scientific independence, rigorous experimental design, and career development. Trainees are encouraged and supported to pursue their own research directions, obtain independent funding, and engage in interdisciplinary collaborations spanning immunology, hematology, bioengineering, and clinical investigation. The laboratory is embedded within a strong research environment with access to outstanding core facilities and institutional career development resources.

Qualifications

Applicants must hold a Ph.D. or MD/Ph.D. in immunology, microbiology, or a related field and should be highly motivated and enthusiastic about contributing to the emerging field of red blood cell immunobiology and its potential disease applications. Individuals requiring visa sponsorship are welcome to apply.

Application Instructions

Applicants should submit the following materials:

• Cover letter describing research interests, relevant experience, and career goals
• Curriculum vitae (CV)
• Contact information for three references
