Hello !
*3-D graphics & animations made by Andrew
I am a scientist with academic research experience and a strong
computer background with a passion for C++, Python and JavaScript.
I have an expertise in Monte Carlo simulations
and have applied thermodynamics as well as
artificial intelligence to study three-dimensional (3-D) solids.
During my PhD, I focused on crystallization theory using
different methodologies.
Dynamic simulations to explore morphology and propagation of features with time
Kinetic Monte Carlo (kMC) simulations have been implemented in the second and third dimension with novel on-lattice theory to shed light on crystallization phenomena.In the kMC simulation I made below, regular crates with less neighboring crates are removed faster, while the "NITRO" crates, when selected, remove 50% of their adjacent neighbors in their 3-D environment:

Tensors for complex topologies
Crystals are typically simulated as blocks (above) or ``coarse grains''. In the case of protein crystals, the crystals may be simulated with a single grain type, which may be a periodic slice of a protein unit ( a collection of molecules ). Tensors were used to simulate crystal structures with a complex arrangement of grains of different types. A common case of these crystals are metal-organic frameworks (MOFs):(tensor: Python; graphics; JavaScript)

Experience
2015 - 2017
XeroxAssociate Engineer
I was a toner chemist and engineer working in Xerox's toner technology and new business sectors. I worked in the lab, pilot scale, and workshop settings where my work went beyond the chemistry of toners alone. I used statistical analysis and my scientific skills to develop toner with features desired by the company and/or Xerox's clients. I obtained my Six Sigma Green Belt certification from Xerox.
2013 - 2015
University of Florida Dept. of Chemical EngineeringResearch Assistant
I entered Dr. Carlos Rinaldi's lab at the University of Florida Department of Chemical Engineering while I was a M.S. student in Chemical Engineering, where my thesis work made me a co-inventor of a patent for a nerve-regenerating hydrogel, an author of a journal article, and most possibly helped me become an expert in colloids while at Xerox.
2009 - 2012
University of Miami Dept. of ChemistryUndergraduate Research Assistant
I started my research career as a Chemistry undergraduate at the University of Miami, where I was initially mentored by Dr. Jamie Walls on the computational modeling of NMR pulse sequences for the first year, and then conducted experimental research in Dr. Roger Leblanc's lab on green syntheses of gold nanoparticles for 2 years.
