Molecular Spectroscopic Imaging Research
We develop and apply molecular spectroscopic imaging technologies to enable discovery-driven research towards marker-based precise diagnosis and/or treatment of human diseases. With integrated expertise in engineering, physics, chemistry, biology, medicine and entrepreneurship, our research team is devoted to: development of imaging tools, discovery of new biology, and delivery to clinic.

Label-free Spectroscopic Imaging
Professor Cheng and his research team has been constantly at the most forefront of the rising field of molecular spectroscopic imaging in technology, science, and clinical translation. Current projects include:
(1) Multiplex stimulated Raman microscopy: spectral acquisition at microsecond scale
(2) Mid-infrared photothermal microscopy: Breaking the diffraction limit by sensing the thermal effect
(3) Vibration-based photoacoustic tomography: listening to chemical bond vibration
(4) Transient absorption microscopy: spectroscopic imaging in the time domain
(5) Volumetric chemical microscopy: label-free, slide-free chemical histology
