What is fault injection, and why are we talking of it here around? The answer lies at the end. As usual. You shouldn't just look at the "trailer".
Some info on fault injection can be found here:

- About Xception, as published on IEEE:
An important step in the development of dependable systems is the validation of their fault tolerance properties. Fault injection has been widely used for this purpose, however with the rapid increase in processor complexity, traditional techniques are also increasingly more difficult to apply. This paper presents a new software-implemented fault injection and monitoring environment, called Xception, which is targeted at modern and complex processors. Xception uses the advanced debugging and performance monitoring features existing in most modern processors to inject quite realistic faults by software, and to monitor the activation of the faults and their impact on the target system behavior in detail. Faults are injected with minimum interference with the target application. The target application is not modified, no software traps are inserted, and it is not necessary to execute the target application in special trace mode (the application is executed at full speed). Xception provides a comprehensive set of fault triggers, including spatial and temporal fault triggers, and triggers related to the manipulation of data in memory. Faults injected by Xception can affect any process running on the target system (including the kernel), and it is possible to inject faults in applications for which the source code is not available. Experimental, results are presented to demonstrate the accuracy and potential of Xception in the evaluation of the dependability properties of the complex computer systems available nowadays

The main reason I'm bringing this to your attention is just to remind you that you should always be with "eyes wide opened" regarding niches. 18 years ago this was a niche market (and it probably still is). It paved the way to a multi-million dollar company that you might be aware of. Will you be able to find yours? How are you planning to make a difference?
(*) One of these persons was a CEO of that company (João Carreira). The other one is the Principal of one of the oldest universities in the world (725 years on): João Gabriel. Henrique Madeira has had several important roles in that same university (as well as Gonçalo Quadros which was a teacher there). I was privileged to watch and participate in the journey from the inside and from the very start and I can say that I pretty much happy with it, so this is the story so far.
