• Successfully observed Anderson localization of ultrasound in 3D dielectric mesoscopic random networks
• Conducted complex multiply-scattering ultrasonic experiments to quantitively analyze coherent and transversely confined signal in 4 “mesoglass” samples to investigate energy localization effects in dielectric materials
• Developed ultrasonic times-of-flight modelling GUI in MATLAB to integrate experimental & theoretical data
• Conducted computational modelling of vibrational modes in COMSOL and optimized spectral analysis procedures by incorporating windowing functions to enhance spectral resolution by 14%
• Incorporated sample-specific time convolution functions into signal processing of transmitted sound intensity profiles, significantly improving short-time accuracy of experimental fitting to theoretical predictions
• Performed numerical integration calculations using linear regression in the diffusion approximation and Self-consistent theory (SCT) to invalidate finite detector width effects on measured intensity in 6 transverse distances
• Automated C, Fortran, and Igor code, resulting in 5x faster processing and modelling of acoustic signal data
• Regularly collaborated with an international team, presented at local material science conferences and at the famous l'École de physique des Houches in France leading to development of SCT theory in dielectric materials- Successfully observed Anderson localization of ultrasound in 3D dielectric mesoscopic random networks - Conducted complex multiply-scattering ultrasonic experiments to quantitively analyze coherent and transversely confined signal in 4 “mesoglass” samples to investigate energy localization effects in dielectric materials - Developed ultrasonic times-of-flight modelling GUI in MATLAB to integrate experimental & theoretical data - Conducted computational modelling of vibrational modes in COMSOL and optimized spectral analysis procedures by incorporating windowing functions to enhance spectral resolution by 14% - Incorporated sample-specific time convolution functions into signal processing of transmitted sound intensity profiles, significantly improving short-time accuracy of experimental fitting to theoretical predictions - Performed numerical integration calculations using linear regression in the diffusion approximation and Self-consistent theory (SCT) to invalidate finite detector width effects on measured intensity in 6 transverse distances - Automated C, Fortran, and Igor code, resulting in 5x faster processing and modelling of acoustic signal data - Regularly collaborated with an international team, presented at local material science conferences and at the famous l'École de physique des Houches in France leading to development of SCT theory in dielectric materials

• Working alongside a team of researchers to conduct experiments using ultrasonic waves in disordered media and to perform rigorous signal data analysis.
• Spearheaded the fabrication project for the thinnest 3D dielectric sintered bead network yet (43% thinner)
• Measured transversely expanding ultrasonic signal transmitted through this novel sample at distances previously unattainable due to noise and discovered an anomalous mechanism in the form of discrepant signal contribution- Working alongside a team of researchers to conduct experiments using ultrasonic waves in disordered media and to perform rigorous signal data analysis. - Spearheaded the fabrication project for the thinnest 3D dielectric sintered bead network yet (43% thinner) - Measured transversely expanding ultrasonic signal transmitted through this novel sample at distances previously unattainable due to noise and discovered an anomalous mechanism in the form of discrepant signal contribution
