Unlike traditional fluid phase separations which have a definitive equilibrium, membrane based processes are inherently out of equilibrium. For this reason, most researchers intuition is formulated on the idea that membrane based separations are controlled by the relative diffusivities of the species being separated. In this presentation we challenge this idea, by showing that the membrane based separations of liquid mixtures using glassy polymer membranes is dominated by the thermodynamic effect of the relative solubilities of liquid species in the polymer membrane.</span></p>\n<p style="margin: 0cm 0cm 8pt;"><span><strong>Biography:</strong></span></p>\n<ul>\n    <li style="margin: 0cm 0cm 8pt;">PhD from Walter Chapmans Group at&nbsp; Rice University (2014)</li>\n</ul>\n<p style="margin: 0cm 0cm 8pt 80px;">Statistical mechanics of interfacial and hydrogen bonding fluids</p>\n<ul>\n    <li style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0cm;">ExxonMobil Research and Engineering - Thermodynamics Group (2014-2019)</li>\n</ul>\n<p style="margin: 0cm 0cm 0cm 80px;">Develop custom thermodynamic models for new processes</p>\n<p style="margin: 0cm 0cm 0cm 80px;">Manufacturing support</p>\n<p style="margin: 0cm 0cm 0cm 80px;">Equation of state development and implementation</p>\n<p style="margin: 0cm 0cm 0cm 80px;">Gas adsorption theory and process conceptualization</p>\n<ul>\n    <li style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0cm;">ExxonMobil Corporate Strategic Research (2019 &ndash; 2022)</li>\n</ul>\n<p style="margin: 0cm 0cm 0cm 80px;">New theory development to predict the separation of complex mixtures with polymer membranes</p>\n<p style="margin: 0cm 0cm 0cm 80px;">Direct air capture process conceptualization</p>\n<p style="margin: 0cm 0cm 0cm 80px;">Gas adsorption fundamentals</p>\n<ul>\n    <li style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0cm;">ExxonMobil Technology and Engineering Company (2022 &ndash; Present)</li>\n</ul>\n<p style="margin: 0cm 0cm 0cm 80px;">Modelling lead in carbon capture new leads program</p>
