It’s an Avocation not Vocation.

davebiopict-1In my early years, I was formally trained as a social scientist, mathematical sociologist, and statistician and applied this training both in academics and the commercial software industry for 45 years (for an overview see the diagram below, for the details see my resume).

During my work career, I picked up specialized knowledge in databases (SQL and NoSQL), natural language processing, AI machine learning and data mining, image processing, data visualization, infographics, and a very long laundry list of computer programming languages (60+ at last count). For the most part, the research I’ve done in the Digital Humanities, including the projects listed in the introductory post, has been for fun (not my official job) and has manifested itself in a series of tutorials I’ve presented over the last few years.

At the end of 2014 I officially retired.  So finally, I have the opportunity to devote substantially more time to these research endeavors.  Towards this end I’ve formed an LLC called Dataffiti that is devoted to this research, and I am using this website and blog as a way to (occasionally) put some of these ideas in print.
