ACS President, Mary K. Carroll, has Ties to UMass Chemistry

headshot of Mary K. Carroll

The 2024 ACS President, Mary K. Carroll, was a postdoc in UMass Amherst Chemistry Prof. Julian Tyson's research group!! During her time in Julian’s group she developed low-cost spectroscopic instrumentation, suitable for undergraduate teaching experiments, to implement time-based measurements in flow injection analysis. In particular, she devised a way to measure the time interval (Δt) between the two peaks formed on the leading and trailing edges of a large volume of analyte solution injected into a single stream of colorimetric reagent under flow conditions for which Δt is directly proportional to the logarithm of the concentration (spectroscopy’s answer to the Nernst equation). She is lead author on three publications, including one in J. Chem. Educ., describing her work (,,
