\newcommand{\mytext}{Firstly, I find Computer Science deeply intriguing as it is the perfect crossover between my two passions of

piqued my interest during the COVID-19 pandemic. My research project from 2024 - 2025, GaitGuardian, started my journey

with signal processing, as I had worked on a project to predict Freezing of Gait (FoG) episodes in Parkinson's

Disease patients using a belt-mounted IMU sensor and machine learning algorithms. In addition to building

an end-to-end hardware embedding with a custom PCB, I also developed a strong understanding of signal processing

me to pursue other related signal processing tasks to boost the final product for Parkinson's patients.

Researching other Parkinsonian symptoms led me to explore tremor detection (uncontroleld shaking of the hands),
|

and I implemented a real-time tremor detection model that involved a bandpass butterworth filter to isolate tremor frequencies
|

between 4-6 Hz, followed by an FFT to extract frequency-domain features. These features were then fed into a lightweight
|

1D CNN, resulting in state-of-the-art 99\% accuracy while limiting false positives. I also looked into signal processing
|

within my FTC robotics team, realizing that IMU data could be used to improve odometry and localization. I implemented a
|

custom Kalman filter to fuse IMU data with wheel encoder reading, significantly reducing drift during autonomous navigation
|

and reducing error buildup over time. }
