Below is a list of my peer-reviewed articles and preprints, with links to DOIs of all open access materials and to files of the few closed access works. These files and a "standalone" list showing the DOIs and links in full (also archived with DOI 10.5281/zenodo.4730019) are at https://github.com/rsookias-research/publications.
If you have any trouble accessing anything, or need further data or information, do not hesitate to contact me.
