Latest Information

Big Data Analytics

This is my short introduction to Practical Genetic Algorithms, part of the Caltech-JPL Summer School on Big Data Analytics.

Caltech Senior Spotlight

Senior Spotlight on Judy Mou, who worked on the Hazard Weather Station Android software

Sonification

A proposal from 2009 that incorporates sonification of scientific data, entitled "Audiovisual cueing of significant events in large multivariate science and security datasets".

Pervasive Computing for Disaster Response

This is an NSF-funded project, in collaboration with UC Irvine and IIT Gandhinagar, India. See the project website here.

The objective of this project is to develop key components of community-based pervasive systems which will allow citizens to respond to disasters.

The Community Seismic Network is a related project.

Sandra Fang, a Caltech SURF student in 2012, built a "Home Hazard Weather Station" - check out her blog here. This is a photo of the completed prototype, which contains sensors for dangerous gasses such as CO and LPG, acceleration, barometric pressure, humidity, sound, light, and radiation (using a Geiger counter).

Cellphone Medicine Project Notes

SURFers Develop Cell-Phone Medical Devices

(SURFers Theresa Juarez (left) and EunJee Lee have contributed to the cell phone medicine project.)

Work with Prof. K. Mani Chandy on various aspects of using cellphones as sensing devices, and in particular as first response medical tools. Here's a proposal we submitted to the Gates Foundation.

This is our idea for a 10c Medical Checkup.

Here is a presentation by Victor Chu and Aleksander Palatnik, two SURF students who worked with us on this project over the Summer 2009.
