Hello and welcome to my blog! My name’s Alex and I’m a Data Scientist at Simulmedia where I work on forecasting, optimization, and building Machine Learning models.
Before this I was an Insight Fellow and did a PhD in math at Washington University in St. Louis. During my PhD I focused on problems in discrete geometry, combinatorics, and graph theory.
I started this blog as a way to document my journey into the nebulous world of “data science” and as a way to learn. Now that I work in the industry I hope to continue using this as a way to explore novel and exciting ways in which science and data influence our everyday lives. I am especially interested in using interactive visualizations to facilitate better understanding of complex datasets and of complex processes in math and machine learning.
I do most of the analysis you see in:
- Python (pandas, scikit-learn, numpy in jupyter notebooks)
- R (tidyr/dplyr/data.table %>% ggplot2/htmlwidgets %<>% caret %>% Rmarkdown/Shiny)
- SageMath (for pure math stuff)
- I’ve also been dabbling in D3.js for interactive visualizations
I also try to keep my blog posts as reproducible as possible. You check out my code on Github.
I have also been known to ride bikes, eat tacos, take photos, play music, and think about urbanism.
Thanks for stopping by!
