The Kavli Nanoscience Institute established the KNI Laboratory Resident Expert program in Fall 2019. Designed to leverage the deep knowledge of its exceptional lab members, the Resident Expert (RE) program recognizes top users in five critical areas of the KNI Laboratory: Lithography, Microscopy, Deposition, Etching, and Wet Chemistry.
Over a six-month period, Resident Experts work alongside technical staff to identify and create useful educational resources that will benefit current and future lab members of the KNI. These resources, e.g. process recipes and procedures, will be compiled into libraries of standardized materials to help minimize exhaustive duplicative efforts across the Lab. Moreover, REs are given a unique platform to contribute thoughtful ideas as to how the KNI Laboratory can evolve to better serve its community.
The first cohort of the Kavli Nanoscience Institute Laboratory Resident Experts is introduced below. We are very excited to work with, and learn from, each of these remarkable individuals!
Dvin Adalian is the current KNI Lab Resident Expert in Wet Chemistry. Dvin is a postdoctoral scholar working in the Scherer research group in the department of Applied Physics. He recently completed his Ph.D. under Professor Axel Scherer in developing novel microfabrication techniques for biomedical devices. He was a graduate student member of KNI Laboratory throughout his Ph.D. and has broad experience in the full range of micro- and nanofabrication instrumentation, from photolithography to thin film deposition and much more.
Jash Banker is the current KNI Lab Resident Expert in Lithography. Jash is a fifth-year graduate student in Professor Oskar Painter’s group in the department of Applied Physics. His research interests lie broadly in the area of hybrid quantum devices. He is working on combining superconducting circuits with opto-mechanical crystals to create a high efficiency quantum transducer. The goal is to create a device that would convert microwave signals from superconducting qubits into optical photons that could then be used to transmit quantum information over long distances.
Jash has been a lab member of the KNI over the past three years and has gained expertise in electron beam lithography. During the fabrication of his devices, he uses the EBPG to write small features and execute multiple beam writes that are aligned within ~50 nm of each other. As a result, he is interested in optimizing the fracturing of small curved features as well as optimizing alignment and minimizing drift on the EBPGs. As part of this program, he hopes to share any tips and tricks he’s learned with the KNI community.
Wen-Hui (Sophia) Cheng
Sophia Cheng is the current KNI Lab Resident Expert in Deposition. Sophia is pursuing her Ph.D. in Materials Science under the guidance of Professor Harry Atwater. Her research focuses on the mesoscale design of photoelectrochemical cells for solar fuels generation for the Joint Center of Artificial Photosynthesis (JCAP). Over the past four years of being a KNI lab member, Sophia has gained extensive experience with semiconductor nanofabrication and materials characterization and is highly capable of utilizing the lithography, deposition, etching, and various analyzing systems in the Lab.
Jake Rochman is the current KNI Lab Resident Expert in Etching. Jake is a fourth-year graduate student in the department of Electrical Engineering. Jake is a member of Professor Andrei Faraon’s research group, where he has been a KNI lab member for the past three years. Jake has experience fabricating nanophotonic structures and superconducting circuit components in the KNI Laboratory.
Changhao Xu is the current KNI Lab Resident Expert in Microscopy. Changhao is currently pursuing his Ph.D. in Professor Wei Gao’s research group in the department of Medical Engineering. He received his BS degree in Materials Science from Fudan University in 2018. He joined the KNI Laboratory in 2019 and has quickly gained considerable experience on TEM and various microscopy instrumentation. Changhao’s research interests include wearable sensors, flexible electronics and biomedical devices for human health.
