The Process Engineering Innovation Lab at TRDDC is collaborating with Professor P. Somasundaran's group at Columbia University in the City of New York on novel nanoparticle systems for coatings, composites, and extraction/release of molecules. The focus of this collaborative project is on synthesis of polymer nanogels and their applications in the development of bioscaffolds for tissue engineering. The specific application that is being targeted in this project is engineering of auricular human cartilages using scaffolds made of biocompatible and biodegradable polymers and nanoparticles.

The overall goal of this research is to develop, and experiment with, static and dynamic program-analysis techniques to improve software quality and reduce the costs of quality-assurance activities. The research attempts to bring improvements in the regression testing activity. It is expected that the resulting techniques would significantly improve the quality of software at reduced cost in terms of both time and effort. The research project is developing techniques to support three important regression-testing tasks: Regression test selection: How to select a subset of test cases for any change in the application Test suite prioritization: How to order the execution of test cases that have been selected for a change, based on the likelihood that the tests will exhibit a different behavior Test suite augmentation: How to identify the parts of a program that may be affected by a change, how to assess whether the affected parts have been adequately tested, and how to generate test data to exercise those affected parts that are inadequately tested.

The Systems Research Lab at TRDDC is collaborating with Prof. John Mitchell and his group at Stanford University. Main focus of this collaboration has been on a theory of privacy and its application in information systems.

Our collaboration builds upon the notion of contextual integrity  framework for understanding privacy expectations and their implications. This framework was developed originally in the literature on law, public policy, and political philosophy. In our research projects, we have formalized some aspects of contextual integrity in a logical framework for expressing and reasoning about use and transmission of personal information. This has resulted in a method for comparing privacy concerns with business process objectives, and for designing business processes so that both goals can be achieved.

As a test of this privacy framework, and as a step toward incorporating it into hospital patient portals (web sites that let patients communicate with doctors and see lab test results), we have represented key portions of the US Health Insurance Portability and Accountability Act (HIPAA) in an executable form. Such a machine understandable codification of HIPAA opens up possibilities for similar codification other standard privacy regulations as well. It also means that computers can do compliance checking of business processes and produce a irrefutable proof of their privateness.
