About me

I am a Chemical Engineering PhD student at Washington University in St. Louis. My thesis is focused on metabolic regulation for efficient biofuel production from non-food crops. The goal is to connect genes and gene expression with fermentation outcomes. When relaxing, I enjoy playing and watching sports including football, volleyball and golf.

Projects

Flux Balance Analysis Web Tool

Flux Balance Analyisis can be used to determine all possible flux configurations given a metabolic reaction network. This tool allows users to perform this analysis in their browser, circuventing the previous need to install python or MATLAB on their computer.

R. opacus Genome Scale Model

Helped lead the building a reaction network the emcompasses the reactions catalyzed by all the genes annotated in the genome of R. opacus PD630. Models like this can be used to better understand how genetic and environmetal changes can lead to beneficial bioprocess outcomes.

R. opacus 13C-MFA

An rigourous analysis of the metabolism of a biofuel producing bacteria. 13C-metabolic flux analysis uses labeled carbon substrates, mass spectometry, and specialized software to calculate intracellular reaction rates.

Clostridium Machine Learning

Clostridium is a bacteria that is able to convert syngas (carbon monoxide, carbon dioxide, and hydrogen gas) into the biofuels ethanol and butanol. The goal of this project is to evaluate the viability to different machine learning algorithms to predict fermentation production rates from time point concentration measurements.

Blackjack Probability Simulator

This website allows the user to simulate the casino game blackjack. It plays blackjack with perfect stategy, keeps track of the running count, and plots the experimentally determined expected value for each count value.

Game of Life

A custom implementation of Conway's game of life. This 'game' is an example of cellular automata, and demostrates how complex systems can emerge from simple rules. I think it is an metaphor for how the universe works.

Cellular Automata

A custom implementation of Steven Wolfram's cellular automata. Rule 30, and cellular automata in general, potentially are the key to understanding how simple rules produce complex structures and behaviour in nature.

Mandelbrot Set Visualizer

A visualizer for the Mandelbrot set that allows up to 10^10 times zoom, and user selected colors.
