Hi, I'm Ben Frey. I'm a PhD student in Applied Physics at Stanford University. I work in the Ultrasound Imaging and Instrumentation lab led by Professor Jeremy Dahl. We work on adaptive ultrasound imaging techniques.
UltraFlex is a framework for iterative model-based ultrasonic flexible-array shape calibration.
[Project Page at benfrey.com/ultraflex]Research for IUS 2025 focuses on advanced aberration correction algorithms for ultrasound imaging. The project aims to compensate for tissue-induced phase distortions via differentiable beamforming for sound speed estimation.
[Project Page at benfrey.com/ius2025]Presented at the Ultrasonics, Ferroelectrics, and Frequency Control Joint Symposium (UFFC-JS) 2024, this project introduces Spatial Gain Compensation (SGC), a novel method for ultrasound image normalization via distributed attenuation estimation with differentiable beamforming and automatic differentiation.
[Project Page at benfrey.com/ius2024]The response of an FBG sensor to arbitrary external stimuli represents a multiphysics problem without a known analytical solution despite the growing use of FBGs in classical and quantum sensing and metrology. Here, we study this problem by first presenting a solid mechanics model for the thermal and elastic states of a stratified material. Finally, we employ the computed surface stress and temperature distributions along the grating to analytically calculate the Bragg shift. [Published in Physical Review E]
Deep Learning (DL) can be applied to lung ultrasound (LUS) images, aiding physicians in the diagnostic process. Our research investigates multiple signal processing stages for DL application to identify B-line features in LUS images from COVID-19 patients. Results are promising to proceed with future COVID-19 B-line feature detection using ultrasound B-mode images as the input to deep learning models. [Published in Proc. of SPIE Vol 12033]
In March of 2020, I started a data visualization company with the goal of creating engaging and elegant interactive data visualizations. I competed with this business concept in the Fowler Business Concept Challenge at The University of St. Thomas and was selected as a semifinalist.
Over two billion people globally rely on open-fire cooking as their primary source of food preparation, presenting health concerns from toxic smoke inhalation. CleanAir, a company that aims to provide sanitary air quality in remote locations through the deployment of carbon credit financed solar cookstoves, finished runner-up in the FGSIC final awards ceremony.
As part of a startup business plan, my DECA partner and I created waveVR with the goal of bringing social virtual reality to everyone. By making inexpensive 3D printed headsets accessible to more people, we envisioned a world where everyone has access to an immersive and interactive platform, lowering barriers to education access.
