A) Pulmonary Surfactant Function and Dysfunction
We established an important surfactant inhibition mechanism and explained it at the molecular level. Moreover, the follow up work led to the discovery of a potential treatment.

B) The Interaction of Nanosized Airosols with the Lung
We discovered that the distribution of the electrical surface potential of pulmonary surfactant at the air-lung interface is highly structured and influences strongly how nanosized particles are retained in the lung (together with my collaborator Dr. Leonenko).

C) Single Cell Force Spectroscopy
My lab uses single cell force spectroscopy to reveal whether, and how, particles of specific properties interact with the cells of the alveolar wall. This method was largely expanded by my collaborator Dr. Shi’s lab, in an application to immunology (published in Immunity and discussed in Science in the Editors’ choice section, and was cited in Nature, Nature Review Immunology and Faculty 1000 only four months after print).
