Professor Erik M Bollt
I am the W. Jon Harrington Professor of Mathematics at Clarkson
Director of C3S2, the Clarkson Center for Complex Systems Science
General Description of My Interest. My core specialty field is the intersection between Applied Dynamical Systems and Data Analytics. Dynamical systems and especially complex and networked systems have lately been informed by data and experimental or remote observations. This brings us strongly to the intersection with what is now described as data analytics and big data methods, including machine learning, graph theory and spectral theory as well as for certain evolution operators, information theory, optimization and also inverse problems methods both variational and statistical inverse problem approaches. This includes image analysis, signals analysis, for a wide range of physical application problems. An especially interesting question has become central which is simply stated, "what causes what", and this leads to the topic of causation inference, and our own tactic called causation entropy.
My office is: CAMP 322.

When I first got to USNA
Here I am in 1973 at USNA. Above left is just after I joined the sailing team. Above right is me in front of Chauvenet Hall, right after I joined the faculty, not too long after I graduated from grad school, and just before my first Nobel prize.
Here I am in 1971. In this picture, I am conferring with current faculty member at USNA, and a former colleague of mine who gave me a horse ride long before we were on the same faculty together.
