Research Interests

• Organic
• Luminescence
• Bioimaging

The Lippert laboratory designs and synthesizes smart organic molecules that switch their luminescent properties in response to a range of stimuli. The molecules are used to image biological chemistry in living cells using fluorescence microscopy and in living animals using small molecule chemiluminescent imaging. Results in these model organisms can be compared to measurements made in human breath samples using luminescent assays. These photoswitching molecules are also used in a new type of volumetric 3D display developed in our laboratory.
