Research Analytical

Analytical Research

Consistently ranked as one of the top analytical programs in the United States over the past four decades, the analytical division is recognized as a world leader in this scientific area.

Following the tradition set by the late Professor Charles N. Reilley, the division extends the frontier of measurement science through a focus on fundamental studies related to chemical analysis and the development of innovative instrumentation. All traditional areas of research are represented, including electrochemistry, mass spectrometry, microscopy, sensors, separations, single cell assays, micro- and nanoscale chemical measurement devices, and spectroscopy.

Research projects span a wide range of chemical analysis science, including microvolume separations and analysis, nanomaterials, proteomics, sensors, single cell/molecule analysis, and surface analysis; for examples of active research projects please see the list below.

The division has a strong alumni base with students working across academia, industry, and national labs enabling exciting career opportunities and networking for our graduate students.

Recent Research Results

Phosphorus Availability Regulates TORC1 Signaling via LST8 in Chlamydomonas

Here, we show that phosphorus (P) regulates TORC1 signaling in the model green alga Chlamydomonas (Chlamydomonas reinhardtii) via LST8, a conserved TORC1 subunit that interacts with the kinase domain of TOR.

Mapping Solvent Entrapment in Multiphase Systems by Electrogenerated Chemiluminescence

We describe the observation and quantification of immiscible solvent entrapment on a carbonaceous electrode surface using microscopy-coupled electrogenerated chemiluminescence (ECL).

Revealing Dynamic Rotation of Single Graphene Nanoplatelets on Electrified Microinterfaces

Here, we combine optical microscopy, single-entity electrochemistry, and numerical simulations to elucidate the dynamic motion of graphene nanoplatelets at a gold ultramicroelectrode (radius ∼5 μm).
