• Developed analytical mesh model optimizing energetic of floating thin film by conjugate gradientdescent algorithm. Reduced simulation running time by over 40%. Applied interface surfacetriangulation and meshing packages through python and C to implement different soft matter experiments in collaboration with experimental researchers to evaluate the important physical parameters and non-dimensionalize their values from experiments to be implemented in the simulation model to investigate the underlying energetic principle.• Implemented data fitting techniques using SciPy for exponential basis functions. Applied Multivariate Linear Regression to predict exponents for multiple physical parameters that are varied in the simulation model to determine their influence in varying the energy of the system.• Developed model experiments studying geometric frustrations on thin films under stress working at the intersection of experimental and computational projects.• Collected data from experiments to perform data analysis using OriginPro Lab software and developed an empirical model for our system.• 3D modelling of novel structures and preliminary data cleaning and extraction of the point cloud data from the model. Image analysis to extract relevant data for surface topography. Estimation of Gaussian and Mean curvatures by local quadratic surface fitting to a point cloud data obtained from the 3D model.

• Improved student understanding of Physics by answering questions individually during lab and class, and held weekly office hours to answer further queries regarding homework assignments, quizzes, and exams with above 90% positive feedback.• Mentored newer teaching assistants by providing instructions for how best to assist students in and out of lecture. Prepared and set up the lab as the lab instructor for the summer semester (2017) assisted by a teaching assistant.
