Murray develops mid-infrared photonic sources and detectors and combines mid-IR spectroscopy with mass-spectrometry imaging to provide complementary optical and biochemical maps of tissue for biomedical sensing.

Zare's group develops laser and mass-spectrometric methods -- including single-cell mass spectrometry and mass spectrometry imaging of neuropeptides -- to chemically profile individual cells and tissue sections with high molecular specificity, alongside long-standing work in microdroplet and chiral-selective chemistry.
