Chris von Csefalvay has been active in the research and development of new technologies, ideas and solutions for perennial problems. Of these, a significant part is unfortunately subject to non-disclosure and governmental secrecy provisions for national security and miscellaneous other reasons. His principal areas of interest and investigation are:
- epidemiology: computational epidemiology, especially modeling disease-avoidant behaviour and general modeling, as well as signal identification from mining passive reporting pharmacovigilance systems (specific emphasis on VAERS)
- operations research: efficient spatial optimisation of critical public resources, mixed quadratic programming, pursuit/evasion
- mathematics: game theory, zero-knowlege proofs of CBRN decommissioning with a specific emphasis on neutron spectroscopy
- computer science: graph algorithms, sensor fusion computation, computer vision and deep learning, autonomous systems
He is currently writing a book on infectious disease modeling for Elsevier. The Computational Modeling of Infectious Disease is expected to be on the shelves in early 2023, along with a rich companion website including sample code and data sets. You can learn more about the book here.
