Cody Harrison Fleming

My name is Cody Harrison Fleming, and I am a PhD candidate in the Department of Aeronautics and Astronautics at the Massachusetts Institute of Technology. I am working under the guidance of Professor Nancy Leveson. Before returning to get my doctorate, I worked for several years in the aerospace industry where I helped develop large satellite systems.


I am interested in modeling risk during concept development of complex, socio-technical systems. An important question about developing new systems, or modifying existing ones, is how new technologies affects system safety. In particular, we are interested in assessing risk in automation- and software-intensive systems that also involve human control, most importantly when the design is immature.


A secondary (but related) interest lies in modern feedback control, dynamics, and modeling.

These days we adopt innovations in large numbers, and put them to extensive use, faster than we can even hope to know their consequences…which tragically removes our ability to control the course of events.
