Intro

My name is Hung and this is my portfolio.

When I was a kid, I watched lots of cartoons/animations, which I believe 99% kids love doing. One day, I watched Ratatouille (a legendary animation by Pixar) and a quote of that animation became my motto:

"Not everyone can become a great artist, but a great artist can come from anywhere."

I started dreaming about the impossible. A country kid dreamed of enrolling for a prestigious high school in the biggest city of the country. A kid from low-class family dreamed of studying abroad to see the world. An international student dreamed of pursuing career in research.

Along this on-going journey, I found numerous ways to enrich my curiosity and to contribute to my community. Hence, I build this portfolio to share my accomplishments so far. I hope my path will cross yours.

Research

This section is still updated. Stay tuned!

Monitoring Oxygen of the Northwest Atlantic

Oxygen is an essential element. Some evidence about the oxygen decline in the Northwest Atlantic (NWA) have been shown in very scattered small local scales. My project aimed to assess the temporal and spatial trend of oxygen in NWA, by using World Ocean Database. World Ocean Database is a valuable source of data but requires a lot of pre-processing and manipulation before our analyses.

Monitoring Harmful Algal Blooms in Lake Okeechobee

Lake Okeechobee (Florida) has been receiving a great nutrient load from agriculture activities. These nutrient loads accelerate the growth the cyanobacteria that ending up depleting the lake's oxygen (hypoxia) and releasing toxins. In this project, we trained photometric data from Sentinel-3 to recognize the blooms in Lake Okeechobee. Although satellite data have great spatial and temporal coverages, the accuracy of the bloom estimation is still concerning. However, the result from satellite data can still be served as a preliminary result, informing the locations that are prone to algal blooms. These locations should be prioritized in the future research.

Traffic Simulation

This is a project from my simulation class. In this class, we used simulation to mimic complex systems and experiment how our intervention would change the system. Traffic system is one example of such system. Interaction among cars determin their speeds, and the overal traffic pattern. By designing this simulation, we found the optimal traffic density to minimize the traffic congestion. We also added as many features as we could: lanes, traffic lights, lane switch, road damanges, etc... In the future works, we would like to improve this simulation to help autonomous car determining its speed to minimize the possibility of traffic congestion.

Network Simulation

This is a another project from my simulation class. Network systems always trigger my immagination. If we want to focus on the interaction among the agents, then network system is the best framework. Network system can be used to represent the following systems: ecological foodweb, molecular interactions, social interactions, etc... Below, we demonstrated a social network where the opinions of a society can either split or reach consensus. This work is inspired by election campaigns.
