Group Alumni

Leo Sifringer was a master's student from the Swiss Federal Institute of Technology in Zurich (ETHZ),  majoring in Micro- and Nanosystems.  He conducted his Master's research project in the Tao Lab between March 2019 and February 2020 as a visiting scholar.  During his time here, Leo developed a custom SEM stage and used it to demonstrate machining with atomic depth resolution.  Leo is now a PhD student back at ETH Zurich in the group of  Janos Vörös. 

Kai Trepka was an undergraduate at Harvard College studying chemistry and physics, working on magnetic probe development for 3D vectorial characterization of materials and fields.  During his time in the group, Kai built a custom CVD system and used it to develop a thinfilm oxide material with the record magnetization and properties.   He also studied magnetic nanoparticles and developed methods to more efficiently handle them.  When not in lab, he could be found volunteering, dancing, playing percussion, and enjoying the outdoors.   He is now a MD-PHD student in the Medical Scientist Training Program at the University of California, San Francisco.

Calder Miller is an undergraduate concentrating in Physics, with particular interests in instrumentation and experimental science.  During his two-year stay in the Tao lab from 2016-2018, Cal built a variable-temperature ultra-high vacuum scanning microsope.  Cal used his custom instrument to study non-contact friction over suspended single-layer graphene.  An avid fast learner and engineer, he has recently joined the laboratory of John Doyle to develop new skills in experimental optics and atomic physics.   Cal is now a PhD student at the University of Colorado Boulder.

Dr. Ying Pan joined us in 2016 from ETH Zurich and pioneered our group's effort in the wafer-scale photolithography of scanning nanowire force sensors.   She has recently moved to MIT to apply her expertise in nanofabrication to photonics and energy science-related topics.
