Abstract.

When hitherto separate areas of science intersect, research opportunities tend to pop up.  So it is with the fields of Document Engineering and Cybersecurity.  We present a summary of recent and ongoing work in our lab, including dealing with malicious PDF files, construction of useful data sets, the use of tensor decomposition, and ongoing work in clustering, symbolic computation, and AI-generated code.  We will point out certain themes in our work, as well as certain outstanding problems.
