Nanotech West Laboratory recently welcomed several new staff members to its team on the West Campus of The Ohio State University. Nanotech West Lab is the Institute for Materials Research’s (IMR) core materials research facility and the largest nanofabrication user facility in the state of Ohio.


Chandan Joishi presents research during the 2019 signing ceremony in Mumbai, India, that helped launch the IIT Bombay-Ohio State Frontier Center.

Dr. Chandan Joishi began working at Nanotech West Lab as a postdoctoral researcher in August 2021. He holds a joint appointment with the Department of Electrical & Computer Engineering. As a member of the Nanotech West Lab staff, Joishi will be supporting research and cleanroom operations, including nano and micro-patterning processes via e-beam and maskless aligner lithography. He has a background in fabrication, characterization, and analysis of semiconductor devices with hand-on-experience in β-Ga₂O₃, GaN, Ge, and Si technologies. Before coming to Ohio State, Joishi was a project research scientist at the Indian Institute of Technology Bombay, where he earned a doctoral degree in microelectronics in 2019. From 2016 to 2018, he worked on β-Ga₂O₃-based high power electronics at Ohio State with Siddharth Rajan, professor of Electrical & Computer Engineering and Materials Science & Engineering, as a visiting scholar through IMR’s Global Partnership Grant Program.


In July 2021, Chip Hirn joined the Nanotech West staff as an equipment technician. His primary responsibilities include providing facility support for the micro and nanofabrication, energy/battery, chemical vapor deposition, and infrared material and device characterization laboratories. Chip supports all lab equipment, especially vacuum systems, by monitoring and performing preventative maintenance as needed, troubleshoots, repairs, and tests semiconductor process equipment including deposition, plasma etch, lithography, and characterization equipment all in support of 24/7 lab operations.


Earlier this year, in January 2021, Kavya Dathathreya joined theNanotech West team as a research assistant. She supportsNanotech West’s research operations and has extensive experience in the design and fabrication of micro and nano-devices for biomedical and semiconductor applications. Her expertise includes layout design, photolithography, nanoimprint lithography, thin film deposition, DRIE, and SEM characterization. Dathathreya earned a master’s degree in 2016 in mechanical engineering from Louisiana State University after receiving a Bachelor of Science in the same field from the PES Institute of Technology, in Bangalore, India.


Additionally, two Senior Research Associate at Nanotech West recently stepped into new roles. David Hollingshead was named the new Manager of Research Operations at Nanotech West Lab. Aimee Price has been named Manager of Nanofabrication at Nanotech West Lab.
