Autonomous surgical robots can significantly reduce human error in oral surgical procedures but experience difficulty accounting for tissue displacement intraoperatively. To address this issue, we developed a model that can accurately predict tissue displacement due to surgical interactions. We used the MATLAB Toolbox Gibbon to create 3D tetrahedral meshes of our porcine tongue model from imported CT scans. Next, we performed a finite element model (FEM) analysis to simulate the setup and interactions throughout the autonomous surgery. We validated our model using Hausdorff distance and Dice Coefficient statistical analysis techniques to compare the physical and simulated deformed models. Show less

Investigated membrane fouling within electrodialysis systems at the University of Mississippi’s Department of Chemical Engineering. Set-up and preformed electrodialysis experimentation on solutions containing specific foulants at different concentrations. Compared solution conductivity over time and calculated current efficiency for each solution. Employed QCM-D to determine rate and total amount of fouling to better understand why the foulants didn’t appear to significantly affect the efficiency of the ED system. Possibly due to only a certain amount of the foulants being able to adhere to the surface. Presented findings in UM Poster Conference. Show less
