Data Analysis Software


Contributor to the open source PmagPy software project and the associated documentation `cookbook‘ (http://earthref.org/PmagPy/cookbook/). Developed the ipmag.py module for the project that enables open and reproducible paleomagnetic data analysis and plotting within the Jupyter notebook environment.
