I am a PhD candidate in electrical engineering at
Princeton University, working in the research group of Prof. Claire Gmachl on quantum cascade lasers.
I am also a Senior Engineer at Primis Technologies LLC, a start-up developing mid-infrared systems technology.

NJN recently filmed a report on our k-space laser. Here's the youtube clip.

News of the k-space paper spread fast around the interent today. It got written up in an article titled "Princeton Researchers Discover New Type of Laser," and I'll be the first to admit the title could be a bit of a stretch,
but the press is still cool. It even made the front page of digg and the top of the digg science page;
don't ask me though what Keira Knightley has to do with anything.

Hometown for the Holidays is a concert hosted by Area 93.3 in Denver that features local Denver bands.
These are pretty decent yet-to-be-discovered bands.
Here's a compiled myspace playlist of the bands.

I'll be presenting the II-VI work
at the MIOMD conference in Freiburg, Germany. Here's the abstract.
02 April 2008
The II-VI work ran on optics.org too. Check out the article here.
01 April 2008
Our II-VI work got picked up by Compound Semiconductor. Here's the website, but there's a free registration to view the page. You can read the article here.

We submitted a couple abstracts to ICPS in Rio. They're posted
on the publications page.

I started a new section on quantum cascade laser physics. I plan to put several write-ups in this section; some of the material might end up in my thesis. Right now, I'm starting with one: a derivation of the QCL figure of merit.
