### Research Assistant @ Carnegie Mellon University
Jan 2019 – Jan 2021 | Greater Pittsburgh Area
Autonomous UAVs for Inspecting Agricultural Water Canals    
Advisor: Kenji Shimada, Founder of Computational Engineering & Robotics Lab, Theodore Ahrens Professor in Engineering

	Using OpenCV library and python-based algorithm, processed images captured by UAVs so that crack elements can be identified, grouped and connected. Current tasks involve implementing Machine Learning techniques to process canal images.   
	Optimized the filter algorithm and corresponding threshold parameters, which yielded an average of 85% correspondence between processed images with ground truth.
	Designed and developed algorithm that grouped adjacent cracks into clusters and connected aligning crack elements to further improve processing accuracies.

### Full Stack Engineer Intern @ Gupta Permold Corporation
Jan 2020 – Jan 2020 | Pittsburgh, Pennsylvania, United States
	Developed E-commerce Website for DiamondLife Gear Co., including new shopping cart, checkout, shipping features written in mainly PHP, HTML and Javascript
	Implemented scripts that manipulates the backend MariaDB database such as caching customer information, retrieving product information and storing shopping cart items
	Made bulk items web orderable by placing price breaks on the product purchased with SQL, PHP and Cookies. Completed algorithm that enabled free shipping based on product specs and quantities

### Project Engineer @ 梦孚(上海)教育科技有限公司
Jan 2019 – Jan 2019
Mengfu Education and Technology Co.
	Developed and designed technological solutions to resolve social/environmental issues. Projects include Autonomous Suitcase, Bio-mechanical Hand, Intelligent Trash Can, Electronic Guard and Autonomous Tennis Collector
	Used Autocad and Fusion 360 to design the mechanical structure and manufacture using laser cutter and various machining tools. Used Arduino, OpenMV and various sensors to implement control and program motion of the projects.

### Research Team Lead @ University of Southern California
Jan 2018 – Jan 2019 | Greater Los Angeles Area
Mathematica Controls Tool
Advisor: Inna Abaramova, Professor at Department of Mechanical Engineering

	Developed a Control System Design Tool powered by Mathematica Packages and Functions, which enables users to not only customize their own control systems from scratch but also to interact with multiple plots to achieve their desired system models 
	As head of the Mathematica Group, I developed Mathematica Packages featuring plotting data, transforming data structures and configuring control systems. Weekly meetings are held by me to maintain constant communication with Graphical User Interface group so that maximum compatibility between subgroups can be achieved, namely, results are updated when user click is captured.
	Improved computing power and usability on existing alternative – Matlab Single-Input-Single-Output tool (SISO Tool). My Mathematica Controls Tool have 20% more computing capability than Matlab SISO tool and have a more refined UI design providing better user experience.

### Research Assistant @ University of Southern California
Jan 2018 – Jan 2018 | Greater Los Angeles Area
Swiss Roll Combustor
Advisor: Paul Ronney, Professor at Department of Aerospace and Mechanical Engineering

	Experimented on the spiral heat exchangers featuring self-sustained and heat-recirculated combustion in either ultra-lean or ultra-rich conditions that are beyond normal flammability limits.
	Designed and Manufactured multiple components structures of Swiss Roll Combustors, including intake/exhaust, metal foils and thermal fins. Moreover, I renovated current version of the experimental setup to include a quick release mechanism, a safer wiring option and a jack platform which securely held Swiss Roll Combustor in place.
	Updated the experiment interface programmed using LabView to include multiple temperature channels integrated in the new design. Worked closely with CFD subgroup to analyze theoretical fluid model with experimental results in order to optimize Swiss Roll design.
	Solved the critical problem of insufficient heat transfer between channel wall by adding fin-shaped structure and the modification increased the heat transfer rate by 21%, which allows leaner fuel mixture to be combusted and larger portion of heat flow to be recirculated.

### Teaching Assistant @ USC Viterbi School of Engineering
