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.

Thesis supervision

Chris von Csefalvay currently supervises thesis students for the Faculty of Mathematics, Budapest University of Technology and Economics. Rising third-years aspiring to a career in data science should get in touch via the contact panel as early as possible. There are typically two thesis slots per semester, and preference goes to students on the Data Science track.
