Experience


UC Berkeley Solar Vehicle Team (CalSol)

Feb 2009 - Present

When I first joined CalSol, on top of helping out with random things like cleaning solar cells, cleaning our workspace, and killing sneaky yet vicious black widows, I mostly worked on soldering/debugging battery monitoring modules and data acquisition development in LabVIEW for the Telemetry program.

From fall 2009 to fall 2010, I was the Telemetry and Analysis Subteam Lead in the Electrical Team. I worked on establishing wireless communication between the race car and the chase car and the data acquistion program in Python in addition to managing approximately ten fellow students. We have designed our very own PCB and our team has never missed a deadline. Starting spring 2011, I have become the Data Lead under Electrical Team to manage the following taskforces: Data Logger, Race Strategy, and Telemetry and Analysis. Although it's definitely been quite management-heavy, I do take a part in the Race Strategy sector and work with a grad student on developing a performance model for analyzing/strategizing purposes.

In addition to my role on the Electrical Team, I have also been the webmaster for CalSol since fall 2010. My main responsibilities include maintaining the public website, CalSol Media Wiki and the server. I have recently remodeled the Media Wiki that we have earlier installed in Fall 2008 and I plan to overhaul the public site over spring break 2011. Please check out the following screenshots for my work on the Wiki.

On a not-as-technical note, I am the Internal Relations of CalSol, and I am in charge of the overall happiness of this team. I bake cookies occasionally and bring them to various meetings, plan bondings, and make sure that people know about the existence of other human beings outside of their subteam. I have been working on a better transparency and communication within the hierarchy of the structure, and it is my goal for people to feel comfortable and happy around anyone they work with.

 
 

Volkswagen Electronics Research Laboratory

Jun 2011 - Sep 2011

During my 15-week internship at VWERL, I worked with Dr. Dirk Langer on the Driver Assistance Systems team. I designed, set up, and built a technology transfer wiki site from scratch using MySQL, javascript, PHP, HTML, CSS, and jQuery. I also helped with the autonomous parking project and wrote a Java program to collect satellite imagery from Google Earth.

Distributed Energy Resources

Feb 2010 - Sep 2010

In Distributed Energy Resources (DER) group, we study customer adoption patterns of microgrid technology through assessments and analysis with the Distributed Energy Resources Customer Adoption Model (DER-CAM). I helped with data collection and coding the data processing unit of DER-CAM. I also spent majority of my time there working on the website.

In addition to my participation in DER group, I also did some technology invesigation with the DC Power group and researched on existing DC standards for potential residential and commercial DC system development.
