Research Staff

John Thomas

John is on the research staff in the department of Aeronautics and Astronautics at MIT. In 2013 he received his Ph.D. from MIT, and he holds bachelor’s and master’s degrees in computer engineering.

John’s work involves creating structured processes for analyzing complex software and embedded systems, especially systems that may behave in unanticipated, unsafe, or otherwise undesirable ways through complex interactions with each other and their environment. By using control theory and systems theory in an STPA framework, more efficient and effective design and analysis processes can be defined to prevent flaws that lead to unsafe or unexpected behaviors when integrated with other systems. More recently he has been applying these techniques to automated systems that are heavily dependent on human interactions and may not only experience human error but may inadvertently induce human error through mode confusion, clumsy automation, and other mechanisms that can be difficult to anticipate.

John’s work also includes defining a formal structure underlying an STPA-based process that can be used to help ensure potentially hazardous or undesirable behaviors are systematically identified. He has also developed algorithms to automatically generate formal executable and model-based requirements for software components as well as methods to detect flaws in a set of existing requirements. The same process can be applied to both safety and functional goals of the system, thereby permitting the automated detection of conflicts between safety and other requirements during early system development.

Soshi Kawakami

soshi_pic
Soshi works as a high-speed rail (HSR) engineer for the Central Japan Railway Company. He has been working recently on SC-MAGLEV (Super-Conducting MAGnetic LEVitation). He has bachelor’s and master’s degrees in mechanical engineering from Kyoto University. His research interests involve enhancing the system safety of HSR transportation. He is now focusing on the ongoing HSR project in the northeast corridor (NEC) from a perspective of safety management as well as technological innovation. He makes a point that, in the planning process, safety should be brought up as a core value of the project because it is deeply related to the institutional framework, the regulations, and the dynamics of the industry — the pace and complexity of innovating technologies and business structures — as past rail accidents in UK and China or recent Boeing 787′s safety problems exemplify. He plans to apply STAMP to risk analysis of the HSR project management in the NEC.

Francisco Luis de Lemos

 Project: Evaluating the Safety of Digital Instrumentation and Control Systems in Nuclear Power Plants
The use of digital instrumentation and controls introduces new challenges to the assurance and licensing of nuclear power plants. The goal of this research is to demonstrate the applicability, feasibility, and relative efficacy of using a new systems approach and hazard analysis technique (STPA) to help meet these challenges. A systems approach has the potential to augment the existing review and certification regime not only to provide a means to assess hazards associated with the introduction of digital technology in nuclear power plants, but also tools to evaluate the extent to which these hazards are adequately mitigated by the encompassing system architecture and to generate recommendations for safety-driven improvement when they are needed.
The research will determine if the current evaluation framework can be made more efficient and more effective by the addition of these new tools and identify which aspects of the current framework might benefit. It will also demonstrate how the new tools can fit within the existing NRC regulatory framework for validating retrofit of old plants and certification of new designs that include safety-related digital systems. While STPA has been used on other complex systems, it has not yet been applied to reactor control systems. The research will demonstrate whether the use of STPA could be an effective method (at the “guidance” level) to meet the requirements set by NRC regulation.
