The Mathematical Sciences Department invites you to a Mathematics colloquium given by Dr. Susan Minkoff, Mathematical Sciences Department of The University of Texas at Dallas.

Trace gas sensors are based on optothermal detection and use a modulated laser source and a quartz tuning fork amplifier to detect small amounts of gases for disease diagnosis via breath analysis and monitoring of atmospheric pollutants and greenhouse gases. We introduce the first mathematical model of a resonant optothermoacoustic sensor. The model is solved via the finite element method and couples heat transfer and thermoelastic deformation to determine the strength of the generated signal.

Coffee will be served in FO 2.610F at 1:30 PM.
