Johanna Nelson Weker graduated in 2005 with a B.S. in mathematics and physics from Muhlenberg College, Allentown, PA. In 2010, she received a Ph.D. in physics from Stony Brook University, NY, where she studied coherent diffractive imaging (CDI) with X-rays, a microscopy technique that eliminates the need for X-rays lenses, which are both inefficient and difficult to fabricate. Much of her graduate research was performed at the Advanced Lightsource in Berkeley, CA. In 2010, she accepted a postdoctoral position at Stanford University working at the Stanford Synchrotron Lightsource at SLAC National Laboratory. With the move across the country, she transitioned to using X-rays to study energy storage materials such as Li-ion batteries under operating conditions. In 2013, she became an associate staff scientist in the Materials Science Division at SLAC, and in 2015, she became a staff scientist within the same division. In addition to a vibrant research group, she helps run the transmission X-ray microscopy on beamline 6-2 at SSRL.
Geoff McConohy is a Ph.D. candidate working under William Chueh at Stanford University. He studies the interfaces of solid electrolytes for application to high-energy-density batteries. He holds a B.S. in engineering physics from the University of Wisconsin-Madison and completed two internships at Sandia National Laboratories, Livermore, CA.
