- Executed 10+ magnetron deposition experiments on spherical silicon mandrels and planar substrates using boron carbide (B4C) as the sputtering material for future ablator capsules for the National Ignition Facility- Design high vacuum chamber model and conducted simulations using SiMTRA and TRIM to simulate the transport of sputtered atoms from the target to the substrate through the argon gas phase for the magnetron deposition experiments - Analyzed surface morphology and roughness of films using optical microscopy and used profilometry to calculate the thickness and stress of films. Conduct nodule analysis of films using scanning electron microscope images and Python code for the understanding and improvement of nodule development at different experimental conditions

- Develop a polyvinylidene fluoride (PVDF) and barium titanate (BTO) paste by experimenting with PVDF concentrations, PVDF-to-BTO ratios, and temperatures, to print the piezoelectric component of a hybrid generator via direct ink writing- Synthesized hollow polymer microspheres of varying diameters through sol-gel polymerization for the fabrication of syntacticfoams. Calculated hardness and elastic modulus of syntactic foams made with different volume percentages of hollow spheres from nanoindentation data- Utilized stereolithography 3D printing to print disposable microfluidics chips with tunable designs to fabricate 20-100 µm sized microspheres- Publication: Gomez, S. G., Irigoyen, A., Gonzalez, S., Estala-Rodriguez, K., Shafirovich, E., Hassan, M. S., ... & Lin, Y. (2023). Fabrication andCharacterization of Hollow Poly

Summer Research Intern- Conducted nondestructive experimental testing on 200+ aluminum additively manufactured cylinders combining resonant ultrasound spectroscopy (RUS) and laser doppler vibrometry (LDV)- Coauthored conference paper, “Additively Manufactured Component Characterization by Machine Learning from Resonance Inspection Techniques,” and documented research results on presentation delivered at the 2023 IMAC conferenceUndergraduate Research Assistant/Research Collaborator - 3D printed different weight percentage alumina ceramic cubic samples and conducted ultrasonic testing experiments to identify differences in properties amongst the different samples- Performed cure depth analysis using 20wt% alumina slurry where the basic exposure, initial exposure, and light brightness were modified to determine the best printing parameters to print dog bone samples- Publication: Gonzalez, Stephanie & Horangic, Sierra & Lahmann, Joseph & Ulrich, Timothy & Shokouhi, Parisa.
