Master's Capstone Project
Python, Ultrasound, 3D Reconstruction, Dimensional Analysis
Jun 2021 - Sept 2022
- Recipient of National Science Foundation grant appointment for capstone project
- Master’s Capstone Project: Created and integrated custom Python solutions to analyze treatment volume using 3D scans from ultrasound data
- Implemented functionality from third-party computer vision framework from scratch when unable to get time to meet with them to answer questions.
- Correlation between estimates and ground truth measurements ~0.95.
- Currently under review for IROS 2023 so I can't provide a link (for now), sorry!

Vision Dataset Augmentation with Stable Diffusion
Python, Diffusion Models, Object Detection
Nov 2022 - Dec 2022
- Used Stable Diffusion to fortify an object-detection dataset with synthetic image variations.
- Achieved ~30% confidence increase for worst-performing images in baseline model
- Achieved ~10% confidence increase for already-well-performing images in baseline model
- The possibilities for this technique are endless, so exciting!

Reverse Image Search (Keypoint matching)
Dec 2022 - Jan 2023
- Wrote program to search arbitrary directories for instances of some query image
- Results cached for fast future access
- Multithreaded

Computer Vision Soft Robot Deformation Measurement

Jan 2020 - Sept 2020
- Implemented pulse width modulation (PWM) and analog-to-digital converter (ADC) module functionality in TI C2000 microprocessor for cannon fire rate control
• Responsible for learning how to initialize those modules and understanding interactions between them
• Synchronized ADC measurements with PWM pulses to ensure valid readings of motor current
- Initialized and implemented I2C module -- TI C2000 microprocessor
• Communication with external EEPROM chip

• Wrote and validated user guide
• Work done in Python and MATLAB

- Gave presentation summarizing work and results to site upper management team
SLAM Pathfinding Bot
Mapping and autonomous path finding robot
November 2019 - December 2019
- ROS, Turtlebot, Astra Pro camera, ArUco tags
- Room mapping with SLAM
- Autonomous navigation around room after mapping
- summoning to predetermined locations (and arbitrary ones with the use of one library we didn't have time to implement...)
Custom Object-Detection Network: Sprinklernet
Senior Capstone Project, object detection neural net, ROS
Fall 2019
-Trained a custom object-detection model with YOLOv3 on Darknet with no previous machine learning coursework or experience (aside from watching a lot of YouTube videos about it)
- Senior Capstone project with Toro
- Smart lawn infrastructure trimmer (trim grass around/over sprinklers, valve box covers, etc, but don't damage them)
- Implemented trained model on Nvidia Xavier running ROS Melodic.
Target Practice Robot
November 2018 - December 2018
- Repurposed large-format inkjet printer slide as linear translation stage for launching platform.
- Robot moves to a random or user-defined position, calculates correct angle, aims, and launches ball into target.
- Arduino Uno for controller
- Reacts happy/sad to making/missing a shot, respectively.
- 3-ball hopper behind target. Launcher autonomously reloads itself after every shot. If no shots are missed, robot operates in loop until stopped: move, shoot, react, reload.
- Budget: $50
R.A.L.F The Line-Following Robot
May 2019 - June 2019
- Mbed controller
- state machine
- complicated tracks
(line breaks, crosses, obstacles to avoid, etc)
- 3d-printed chasis and wheels
- collect ping pong balls on the track with no moving parts
