Postdoctoral Associates: The role of Mast cells in the Vascular Pathology of Shock and Ischemia/Reperfusion Injury.

Two postdoctoral positions are available jointly in the Department of Anesthesiology and Department of Pathology at Duke University Medical Center. Projects are funded for up to 4 years by recently approved grants from the NIH and the American Heart Association and will examine the role of mast cells at the vascular/tissue interface. Specifically, they will determine:

  1. Vascular pathology during the transition of sepsis to septic shock. This project aims to determine the triggering events for development of shock in sepsis using various mouse models and assays of vascular permeability, microvascular perfusion (photoacoustic imaging) and shock (pressure sensing telemetry implants).

  3. Vascular permeability, neutrophil recruitment and neuronal injury after cardiac arrest. This project examines how mast cells shape neuronal outcomes in a mouse model of cardiac arrest using functional neuro-testing and tissue assays of inflammation and vascular injury.

We apply a wide spectrum of techniques used in Molecular-, Cellular Biology, and Immunology, advanced in vivo approaches in mice and strains of genetically modified mice, and have access to biobanked clinical samples for confirmatory analysis. Both projects are highly multidisciplinary and involve close collaborations with researchers from Bioengineering, Infectious Diseases and Neuroradiology at Duke, and from the Department of Biochemistry and Biophysics at UNC (20min from Duke).

Interested candidates should provide cover letter, CV and contact information of 2 references. Please send applications to Dr. Jörn Karhausen, Department of Anesthesiology (jorn.karhausen(at)duke.edu) or Dr. Soman Abraham, Departments of Pathology, Immunology, and Molecular Genetics and Microbiology (soman.abraham(at)duke.edu).

We are searching for motivated and outstanding MSc/PhD/MD/PostDoc research students to take on challenging projects in the field of Allergy, Cancer, Corona virus and Antibody-mediated therapy

Lab work includes immunological, molecular biology and microbiology methods, as well as in vivo mouse models of disease and work on human cells.

 

Projects:

  • Mechanisms underlying the pathophysiology of skin and airway allergic disease (Atopic dermatitis and asthma)
  • Resolution processes of allergic inflammation
  • Activating and inhibitory receptors on mast cells and eosinophils
  • The role of inhibitory receptors on solid tumors (from melanoma to colon cancer)
  • The interaction of mast cells and eosinophils with bacteria and fungi
  • Corona virus: are mast cells and eosinophils involved in host protective or offensive mechanisms?
