If you want to know where I work you can check out this webcast. TEAM I at NCEM will be one of the facilities showcased. The microscope is being fixed and in pieces right now, but it should be cool to see.
+Huolin Xin, our collaborators and I published a paper in this issue of Microscopy and Microanalysis. We used the Cc corrector of the TEAM I to do 3D confocal sectioning. This could be a "killer app" for the Cc corrector. It certainly makes 3D imaging much easier compared to traditional tomography.

I was asked to share some of my research at an event called Eight Big Ideas hosted by LBNL as part of Science at the Theater in Berkeley, CA. I was one of 8 scientists given 8 minutes to break down one idea for a general audience. The event was great and I really enjoyed the opportunity to speak at an event like this. My speech "Imaging Atoms in 3D" starts at about the 19:30 mark, but the other speeches are very interesting, too!
I obtained my Bachelors of Science from the School of Applied and Engineering Physics at Cornell University in 2003 after also completing internships with the NNIN and Sandia National Laboratories. I remained in Ithaca, NY at Cornell University to pursued my doctorate (PhD) in applied physics working with Dr. David Muller. My main research activities involve scanning/transmission electron microscopy (S/TEM) with a focus on three-dimensional electron tomography. Electron tomography is a technique to reconstruct 3D structures from a series of 2D images (similar to a medical CAT scan) thus allowing quantitative investigation of buried features, such as wire barrier layer thicknesses and material voids. I developed the incoherent bright field (IBF) STEM imaging technique to reconstruct ultra-thick cross-sections of nano-scale semiconductor devices. Another goal of my research is a microscopic understanding of the bulk and interfacial properties of copper wire barrier materials for improvements in barrier thickness and adhesion. This interface has proven a major source of failure in integrated circuits affecting the yield and lifetime of modern computer chips. Electron energy loss spectroscopy (EELS) allows spatially resolved measurements of a material's local chemistry and electronic structure with atomic accuracy.
I graduated from Cornell University with my PhD in applied physics in June 2009. I am continuing my electron microscopy research at Lawrence Berkeley National Laboratory with the National Center for Electron Microscopy. I am currently a collaborative postdoc at NCEM and am responsible for starting a user-based tomography program. I am currently working with the TEAM 1.0 triple corrected (Image, probe, chromatic) microscope outfitted with the TEAM tilt-rotate stage.
I have brought my dog to Happy Hounds numerous times and the service always impresses. They have play groups for every size of dog, and the staff is very attentive. My dog loves other dogs and plays all day long. She always comes home happy and completely worn out from all the activity. This is a great doggy daycare. Highly recommended!
