About

Hi there! My name is Justin and I am currently a masters student at Carnegie Mellon University (CMU) in the Electrical and Computer Engineering Program (ECE). My interests are focused in embedded systems, machine learning, and computer architecture. I am working on several proejcts relating to edge-ML: how we can apply computationally intensive algorithms on resource-constrained embedded and mobile platforms. I am really passionate about collaborating with others to build amazing things, so browse my projects and feel free to reach out!

Outside of software development and engineering, I love spending time outdoors, vibing to 80’s jazz fusion music on my AT turntable, and cooking all kinds of international dishes!

Experience

Lawrence Livermore National Lab

Lawrence Livermore National Lab
I originally interned at LLNL over the summer of 2017, and joined part-time during university to support the software side of the project longer-term. I am continuing to develop vision algorithms for scientific measurements, but I am also working on streamlining our team’s workflow by using the latest workflow automation tools like Dagster.

Projects

Evaluation of ASR in Musical Environments

Evaluation of ASR in Musical Environments
ASR is used heavily in eyes-busy or hands-busy situations and often time the user may be speaking over noise. My peers and I are particularly interested in how music effects ASR decoding. We use several music datasets of varied genre or broken-down instrumentation to allow us to perform in-depth anaysis of how different aspects of music influences speech recognizer’s performance. We then train a new model from what we have learned to see if we could improve the original model’s performance.

Education
