Programs and Projects
Fluid Suspensions & Emulsions

We are trying to help take colloidal rheology understanding beyond uniformly charged spheres to particles with more complex interactions, through … more

Frequency Comb Spectroscopy

We use frequency combs based on ultrafast mode-locked lasers to perform precision spectroscopy in the near- and mid-infrared domains, for rapid, … more

Microresonator Device Research

With micro-resonators (fabricated in house or by collaborators) we are developing microcombs, integrated reference cavities and low-noise laser … more

Calcium Optical Beam Clock

A simple, compact alternative to the highest performing optical standards, the Ca clock uses a thermal beam of neutral atoms with one or two … more

Optical Cavities for Laser Stabilization

Optical cavities are essential elements of optical atomic clocks, as they serve to pre-stabilize the clock laser. Our Group is currently … more

Modeling and Simulation of Nanofabrication (Archived)

Most manufacturing has historically been based on top-down fabrication and assembly. With rapid advances in nanotechnology, there is increasing … more

Software
NIST's Integrated colony enumerator (NICE)

Enumeration of bacterial colonies on an agar plate is simple in concept, but automated colony counting is difficult due to variations in colony … more
