Aju Jugessur hails from the tropical island of Mauritius. He received a Ph.D. degree in Optoelectronics, Electronic engineering, with a focus on Nanofabrication, from the University of Glasgow, followed by a postdoctoral fellowship at McGill University. His expertise is in the area of photonic devices, nanolithography, nanofabrication, with extensive experience in the design, development and management of state-of-the-art nanoscale material characterization and cleanroom facilities for research, education and training. He was a Senior Research Scientist in the Department of Electrical and Computer Engineering at the University of Toronto, where he spearheaded the establishment and development of a state-of-the-art Nanolithography Facility. He has introduced several courses on micro- and nanofabrication and developed the first online real-time labs course in this area. He founded and directed the University of Iowa Microfabrication Facility from 2012 to2018. He led the design, construction, and set-up of the COSINC material characterization and cleanroom facilities at CU Boulder. He is a Senior Member of IEEE.

Facility Manager, COSINC-CHR

   borsa@colorado.edu

Tomoko Borsa was born in Tokyo, Japan and completed a BS and MS at Waseda University, where she was exposed to the field of scanning electron microscopy for the first time. She then earned a Ph.D. in Materials Science with an emphasis on Chemistry of Materials from Colorado School of Mines. She also received an MS in Electrical Engineering (Photonics and Nanostructures) from University of Colorado Boulder. She also has extensive experience in the area of micro/nanofabrication including electron beam lithography and related process development.

Facility Manager 

   Adrian.Gestos@colorado.edu

Adrian joined CU Boulder in September 2020. Prior to CU Boulder, Adrian worked with the water electrolysis start-up AquaHydrex, managing a team to scale up electrode production as well as conducting fundamental studies into catalyst and membrane performance. Adrian obtained a PhD in Materials Science from the University of Wollongong (UOW) in Australia, focusing on the properties of polymer nanofibers investigated with atomic force microscopy. As a facility manager, Adrian assists COSINC operations, mainly on the material characterization suites, including equipment maintenance, user training and PPMS. He also provides support on the MIMIC instruments on main campus.

Cleanroom Facility Manager 

   Dylan.Bartusiak@colorado.edu

Dylan has been a member of the CU community since August 2019 where he was a part of the New Energy Devices laboratory in ECEE. He is a proud Colorado native who is happy to be able to work on a campus like the University of Colorado which has been a part of Colorado history since the late 1800s. With an education from the School of Mines in Physics and Materials Science, he served as a lab manager and process engineer designing and fabricating metal-insulator-metal diodes for several years. Having spent a large portion of his time working in cleanrooms in Santa Barbara, California, and at CU Boulder, he has found a new home in the COSINC fabrication facility where he manages the cleanroom operations, including equipment maintenance and user training.

Research Associate

   Nicholas.Weadock@colorado.edu

Nick Weadock (he/him) joined CU Boulder in April 2021 after completing a postdoctoral appointment at the SLAC National Accelerator Laboratory. He received his Ph.D. in Materials Science at the California Institute of Technology (Caltech) where he studied thermodynamics and kinetics of phase transitions in metal hydrides. He has expertise in hydrogen storage and X-ray and neutron characterization of quantum and energy materials. Nick provides support and training on the COSINC’s suite of X-ray characterization tools and develop experimental platforms for in-situ characterization of materials and devices.
