Research
Our laboratory specializes in conducting preclinical testing using experimental models of asthma and pulmonary arterial hypertension. Additionally, we engage in collaborative research to investigate the role of abnormal blood vessels and bone marrow stem cells in the development and progression of lung diseases. Our team focuses on providing skilled biotechnological services, such as 4-dimensional functional lung imaging, measurements of airway hyperresponsiveness, assessment of right ventricle hemodynamics, and high-dimensional spectral flow cytometric immunophenotyping of inflammatory and lung-resident cells.

Careers
Research News
Renowned lung disease researcher Dr. Kewal Asosingh has established the Cleveland Clinic Flow Cytometry program as a world class institution, setting internationally recognized standards.
Researchers studied how the vascular endothelium contributes to the onset of airway inflammation, a new discovery and break from research over the past 50 years that focuses on epithelium only.
Funding was awarded from the National Institutes of Health (NIH) to purchase a leading-edge preclinical scanner from 4Dx Limited, a Melbourne-based medical technology company.
