Summary

I'm an expert researcher in data analysis for Zooniverse citizen science projects, building general purpose data analysis tools, and helping to make astronomy more accessible to people with vision impairments.

Biography

I'm a Citizen Science and Outreach Fellow for the Institute of Cosmology and Gravitation and act as the Technical Lead of the Tactile Universe project.  I joined the ICG in 2014 after completing my PhD at Drexel University in Philadelphia.

Research interests

My current research interst fall into several catagores:

  • Zooniverse data analysis: As a developer for the Zooniverse I am building a general purpose data aggregation tool box to help research turn clicks into science
  • Tactile Universe: I am the technical lead for the Tactile Universe project which creating 3D printable tactile models of galaxies to help teach students with vision impairments about astronomy.
  • Global Earth Model: As part of the GEM team I am designing and building the coding infrastructure that will be used to create a digital twin of the earth
  • Statistics: I am interested in learning about advanced statistical techniques and learning how to apply them large data set
