Mark Liu Lab
- Research in the Mark Liu Lab explores several areas of pulmonary and respiratory medicine. Our studies primarily deal with allergic inflammation, chronic obstructive pulmonary disease (COPD) and asthma, specifically immunologic responses to asthma. We have worked to develop a microfluidic device with integrated ratiometric oxygen sensors to enable long-term control and monitoring of both chronic and cyclical hypoxia. In addition, we conduct research on topics such as the use of magnetic resonance angiography in evaluating intracranial vascular lesions and tumors as well as treatment of osteoporosis by deep sea water through bone regeneration.
Research Summary
Dr. Liu studies the mechanisms of inflammation in the lung with an emphasis on the response to allergen exposures and the role of macrophages, dendritic cells, and T cells in allergic inflammation in human studies. He conducts multicenter clinical trials sponsored by pharmaceutical companies or the NIH to develop new treatments for severe asthma.
