I have been engaged in the development of mathematical models describing the inception and propagation of pathogens, behaviors, and influence over time – towards understanding the role these flows play in emerging structures of logic, regulation, and immune function exhibited by “social networks” and other macro-level social collectivities.  Between 1996-2004, I was a research scientist at the U.S. Naval Research Laboratory, where I developed large distributed geodata systems.   I am presently Professor of Mathematics and Computer Science at John Jay College.  My work is transdisciplinary, ranging formal to the subjective, emic to etic, deconstructive to engineering.  Certain other information can be found on my website.
