To achieve this, I work with tools that use standards such as RDF and JSON-LD to store and transmit semantically rich data, use ontologies written in OWL to reason over data, and use descriptions in SHACL and ShEx to validate data and document data models. Where existing tools are unavailable or inadequate, I write software tools to fill this need. My current projects focus on genetic, disease and other biomedical data, but I look forward to working with other kinds of data in the future. I work primarily in Scala to build these tools.</p><p><ul class="uncompressed roleProducts"><li id="Semantics-web-technologist-the-Renaissance-Computing-Institute-(RENCI)-at-Chapel-Hill-North-Carolina-USA-Center-for-Cancer-Data-Harmonization-(CCDH)"><a class="section-link" href="#Semantics-web-technologist-the-Renaissance-Computing-Institute-(RENCI)-at-Chapel-Hill-North-Carolina-USA-Center-for-Cancer-Data-Harmonization-(CCDH)">§</a><strong>Project:</strong> <a href="/projects#Center-for-Cancer-Data-Harmonization-(CCDH)">Center for Cancer Data Harmonization (CCDH)</a> (<span title="October 21, 2019, 3 years, 6 months and 16 days ago">Oct 2019</span> <span class="no-title-dash" title="1 year, 1 month and 29 days">to</span> <span title="December 20, 2020, 2 years, 4 months and 17 days ago">Dec 2020</span>): <!-- -->I work on the CCDH Tools and Data Quality team at RENCI.

SciNames imports multiple taxonomic checklists into a single XML file, and then generates lists of changes between those checklists. Users can then use the GUI to annotate these changes, recording why each change had occurred and what sort of change it was. SciNames can then calculate some statistics on the changes.</li><li><a class="section-link" href="#PhD-in-Ecology-and-Evolutionary-Biology-Ecology-and-Evolutionary-Biology-(EBIO)-at-Boulder-Colorado-USA-PhD-dissertation-https:doi.org10.31237osf.ion2kh5">§</a><strong id="PhD-in-Ecology-and-Evolutionary-Biology-Ecology-and-Evolutionary-Biology-(EBIO)-at-Boulder-Colorado-USA-PhD-dissertation-https:doi.org10.31237osf.ion2kh5">Citation</strong>: <strong><em>Gaurav Vaidya</em></strong> <!-- -->(<!-- -->January 19, 2018<!-- -->)<!-- --> <a href="https://doi.org/10.31237/osf.io/n2kh5">Taxonomic Checklists as Biodiversity Data: How Series of Checklists can Provide Information on Synonymy, Circumscription Change and Taxonomic Discovery</a>.<!-- --> <em>Ph.D. Dissertation</em> <strong></strong>.</li><li><a class="section-link" href="#PhD-in-Ecology-and-Evolutionary-Biology-Ecology-and-Evolutionary-Biology-(EBIO)-at-Boulder-Colorado-USA-PhD-dissertation-https:doi.org10.1371journal.pone.0195736">§</a><strong id="PhD-in-Ecology-and-Evolutionary-Biology-Ecology-and-Evolutionary-Biology-(EBIO)-at-Boulder-Colorado-USA-PhD-dissertation-https:doi.org10.1371journal.pone.0195736">Citation</strong>: <strong><em>Gaurav Vaidya</em></strong>, <a href="https://avibase.bsc-eoc.org/about.jsp">Denis Lepage</a>, <a href="https://sites.google.com/site/robgur/">Robert Guralnick</a> <!-- -->(<!-- -->April 19, 2018<!-- -->)<!-- --> <a href="https://doi.org/10.1371/journal.pone.0195736">The tempo and mode of the taxonomic correction process: How taxonomists have corrected and recorrected North American bird species over the last 127 years</a>.<!-- --> <em>PLOS ONE</em> <strong>13</strong>(4)<!-- -->:e0195736<!-- -->.</li><li><a class="section-link" href="#PhD-in-Ecology-and-Evolutionary-Biology-Ecology-and-Evolutionary-Biology-(EBIO)-at-Boulder-Colorado-USA-PhD-dissertation-https:doi.org10.3897zookeys.420.7089">§</a><strong id="PhD-in-Ecology-and-Evolutionary-Biology-Ecology-and-Evolutionary-Biology-(EBIO)-at-Boulder-Colorado-USA-PhD-dissertation-https:doi.org10.3897zookeys.420.7089">Citation</strong>: <a href="https://avibase.bsc-eoc.org/about.jsp">Denis Lepage</a>, <strong><em>Gaurav Vaidya</em></strong>, <a href="https://sites.google.com/site/robgur/">Robert Guralnick</a> <!-- -->(<!-- -->June 25, 2014<!-- -->)<!-- --> <a href="https://doi.org/10.3897/zookeys.420.7089">Avibase â a database system for managing and organizing taxonomic concepts</a>.<!-- --> <em>ZooKeys</em> <strong>420</strong>:117â135<!-- -->.</li></ul><li id="PhD-in-Ecology-and-Evolutionary-Biology-Ecology-and-Evolutionary-Biology-(EBIO)-at-Boulder-Colorado-USA-Small-projects-during-my-PhD"><a class="section-link" href="#PhD-in-Ecology-and-Evolutionary-Biology-Ecology-and-Evolutionary-Biology-(EBIO)-at-Boulder-Colorado-USA-Small-projects-during-my-PhD">§</a><strong>Project:</strong> <a href="/projects#Small-projects-during-my-PhD">Small projects during my PhD</a> (<span title="January 1, 2011, 12 years, 4 months and 6 days ago">Jan 2011</span> <span class="no-title-dash" title="6 years, zero months and zero days">to</span> <span title="January 1, 2017, 6 years, 4 months and 6 days ago">Jan 2017</span>): <!-- -->Some small software projects I worked on during my PhD.</li><ul class="uncompressed"><li><strong>Software</strong>: <a id="PhD-in-Ecology-and-Evolutionary-Biology-Ecology-and-Evolutionary-Biology-(EBIO)-at-Boulder-Colorado-USA-Small-projects-during-my-PhD-BibURI" href="https://github.com/gaurav/biburi">BibURI</a> (<span title="October 1, 2013, 9 years, 7 months and 6 days ago">Oct 2013</span> <span class="no-title-dash" title="3 months and 26 days">to</span> <span title="January 27, 2014, 9 years, 3 months and 10 days ago">Jan 2014</span>)<!-- -->: <!-- -->A Ruby Gem to extract BibTeX information from a number of bibliographic resources, such as DOIs and COinS webpages.

Apart from the website itself, the service featured a simple API which can be used to submit documents for processing programmatically.</p><p>I was lead developer of OCR Terminal right from project inception. I have written all of OCR Terminal's underlying code, first as a Perl/CGI application, and later as a Perl/Catalyst application. I am particularly proud of designing the public API, which is used by our own desktop client, several in-house tools, and several clients of ours who use it for both bulk processing and as a backend for their own software.</p><p>I also manage OCR Terminal's main server administrator, responsible for maintaining all the servers and backend components.
