Research
Current projects
I am currently working with Deborah Estrin on:
Urban Sensing (Participatory Sensing) focuses on developing technological advances for using embedded and mobile sensing in order to enhance civic life and invigorate public space. Particularly, it embraces the concept of participatory sensor networks where cell phones enable public and professional users to gather, analyze, and share local knowledge. The application model follows the idea of having campaigns for such purposes as urban planning, public health, cultural identity, and natural resource management.
Past projects
I've been involved with these other projects at UCLA:
- Rewind is a scalable system of everyday mobile phones and supporting web services that we developed to explore how client- and server-side image processing can be used to both lower bandwidth needs and streamline user navigation. While the system is designed to accommodate a range of image processing algorithms, in this first prototype we rely on simple filtering techniques to evaluate our system concept. Simple image processing on the phone can address the narrow-band and intermittent upload channels that characterize cellular infrastructure, while more sophisticated processing techniques can be implemented on the server to further reduce the number of images displayed to users.
I earned my Master's at Carnegie Mellon University under Priya Narasimhan and Rajeev Gandhi, where I worked on Castor, a secure code-update protocol for resource-constrained embedded sensing systems based on symmetric crypto-system.
