The group went blueberry picking again this summer.
Sarah, Clayton, and Sampad all returned to Rice for the graduation and hooding ceremonies. Congratulations to these fine doctors.
Welcome to our newest group member, Mi Yan!
The Rice alumni magazine, Sallyport, profiled the ultracold plasmas experiment in its fall 2007 issue. Be sure to watch the video on the website!
All four of our recently graduated lab members landed on their feet in interesting and challenging jobs:
- Clayton is at NIST in Gaithersburg, MD on an NRC fellowship.
- Sarah has joined the faculty on a teaching fellowship here at Rice.
- Sampad is doing analysis for an exploratory oil firm in Houston.
- Priya is straddling the divide between R&D and sales for New Focus in San Jose, CA.
Clayton successfully defended his doctoral thesis. Congratulations!
A flurry of activity this week resulted in the successful doctoral defenses of Sampad and Sarah. Congratulations to them both! Pictures here.
Tom and the ultracold plasma crew are featured in Rice News.
Andrew is graduating. His senior thesis is titled "Photoassociative Spectroscopy of Strontium Along the 1S0-3P1 Transition using a Littman/Metcalf Laser". Congratulations!
