Principal Investigator


Holger Müller

hm [at)

Awarded his first patent at the age of 14, Holger continues his inventive spirit as a physicist applying matter-wave interferometry to fundamental and exotic physics. 



Richard Parker

rhparker [at)

I did graduate work at the University of Chicago/Argonne National Laboratory, completing the first electric dipole moment (EDM) measurements of 225Ra. I currently work on another precision measurement project group at Berkeley, measuring the fine structure constant. My interests include history, hiking, and travel.

Xuejian Wu

xuejianw [at)

I am a postdoc in Prof. Müller's group and I am currently working on a transportable, multi-axis atom interferometer. I received my PhD from Tsinghua University in January 2015.


Osip Schwartz

I am working on phase contrast electron microscopy, a project combining laser-controlled matter interference and electron microscopy for imaging of biological macromolecules. In my PhD in the Weizmann Institute of Science, Israel, I worked on quantum imaging and super-resolution optical microscopy.


Sara Campbell

sarac [at)

I did my PhD in Jun Ye's group at JILA, where I tore down the world's most accurate clock and hung out in the electronics shop with the guy who puts the "H" in "PDH."  I am very excited to be working on the phase contrast electron microscopy project, where such laser locks will improve contrast, opening the door to new biomolecules that were previously too small or too flexible for single particle cryo-EM.  Outside of lab, I enjoy climbing, mountaineering, and backcountry skiing, and being new to the area, I'm looking for more partners, so please shoot me an email!

Matt Jaffe

mjaffe [at)

I did my undergrad at Penn State, where my addictions to physics and ultimate frisbee took control over the rest of my life. Outside of the lab, I play for the San Jose Spiders and Oakland Guerrilla. I work on the cavity interferometer.

Eric Copenhaver

eric.copenhaver [at)

I am motivated to apply the rich toolkit of Atomic, Molecular, and Optical physics to a breadth of problems in metrology, technology, and fundamental physics. While I love olympic lifting and my wife, my primary life aspiration is to make it big with Holger as the lead singer and guitarist in a band called the Phrygicists.

Weicheng Zhong

zhongw [at)

I received my Bachelor's degree in physics from the University of Science and Technology of China in 2014. I am working on the atomic fountain project. Outside of lab, I am a big fan of Manga and dumplings.



Victoria Xu

vxu [at)

After studying physics at UC Santa Barbara, I moved back up to the bay for graduate school at Berkeley. I'm excited about studying gravity, fundamental physics, and generally, searching for new physics with complex, fun, table top experiments. I am especially excited everyday to work with our cavity interferometer experiment! Outside of lab, I try to enjoy all the sunshine I can get before heading back. 

Jeremy Axelrod

jaxelrod [at)

I received my B.S. in Engineering Physics at UC Berkeley before continuing at Berkeley as a Physics graduate student. I like atomic, molecular, and optical physics because it is broadly applicable to the development of both practical techniques and fundamental science. I work on the phase contrast electron microscopy project. Outside of lab I enjoy aviation, hiking, skiing, photography, and the hallway.

Zachary Pagel

I received my B.S. from Tufts University where I studied engineering science, physics and math. I love being outside whenever possible, listening to music, cooking, and working on really cool experiments. I'm currently helping to build our next-generation atom interferometer to measure the fine-structure constant.


Andrea Herman

amherman [at)

I did my undergrad at MIT, where I studied physics and literature. Here at Berkeley I’m excited to work on the phase contrast electron microscopy project and to consume many lab snacks in the process. When not in lab I can be found furthering my love affairs with poetry, yoga, hiking and vegetables.




Carter Turnbaugh

carterturn [at)

I am an undergraduate student studying physics and applied mathematics. I am enjoying working on the laser phase contrast electron microscopy project. Outside of the lab, I enjoy programming and playing with my cat (who also enjoys lasers).


Yuanhang Yang

yyhshdu [at)

As an exchange undergraduate student from China , I majored in theoretical physics at my home university (Xi’an Jiaotong University). Here at Berkeley I enjoy working with mini G group and help to model the gravity field. Outside lab I am in favor of animation and Japanese (just smattering :p).


Yanyan Zhu

yyzh [at)

I am an exchange undergraduate student from University of Chinese Academy of sciences, majored in physics and minored in astronomy. In Berkeley, I am helping with gravity measurement and learning its control system. Outside of the lab, I enjoy origami and playing badminton.

Eric Planz

ericplanz [at)

I received my B.S. in physics at the Technical University of Darmstadt, Germany, before continuing at Darmstadt as a Master’s degree student. Here at Berkeley, I am working on an upgraded laser amplifier system for the phase contrast electron microscopy project. Besides my studies, I enjoy playing piano and playing trumpet in a German marching band.
