Thursday, June 30, 2016

The Materials Department at UCSB would like to congratulate our 2015-2016 Ph.D. graduates and welcome them into the Materials Alumni family. Twenty-seven students had their degrees conferred in Fall 2015-Summer 2016. We had a chance to learn about the new journeys that some of our graduates have begun. Take a look and see the exciting places they have headed to!


Lars Bjå​lie, Ph.D. '16Understanding and Engineering Two-Dimensional Electron Gases in Complex Oxides, advised by Prof. Chris Van de Walle

Lars Bjålie returned to his home country Norway after completing his PhD, and started working at BearingPoint as a consultant within data and analytics.

Matthew Gebbie, Ph.D. '16, Tuning Electrostatic Interactions in Confined Soft Matter, advised by Prof. Jacob Israelachvili

Matt is collaborating with Professors Nick Melosh and ZX Shen at Stanford University as one of two 2016-2018 GLAM Postdoctoral Fellows. During his postdoctoral studies, Matt aims to develop optically-active diamond nanomaterials that will enable the molecular-scale observation of electric fields and electromagnetic fluctuations in active soft matter and living systems. Matt subsequently plans to pursue a faculty appointment at a research university.


Brian Hoskins, Ph.D. '16Processing and Characterization of Titanium Dioxide Based Resistive Switches, co-advised by Prof. Dmitri Struckov and Prof. Susanne Stemmer

After graduating UCSB with his Ph.D., Brian was awarded a National Research Council Postdoctoral Fellowship to work at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. At NIST, Brian works with research scientists in academia, government, and industry on the development and characterization of neuromorphic circuits using nanotechnology. The goal of this research is to develop ultra-low energy integrated circuits which can perform deep learning and other unconventional forms of computing orders of magnitudes more efficiently than with conventional CPUs and GPUs. Many of the skills Brian developed at UCSB have been critical for his work at NIST, especially in the areas of electrical measurement, nanofabrication, and materials characterization.

Nate Kirchhofer, Ph.D. '16Enhancing Bioelectrochemical Conversion: Molecular Modifications for Amplified Transmembrane Electron Transfer, advised by Prof. Guillermo Bazan

Nate is currently working at the Asylum Research as an Applications Scientist. At AR, his expertise is in physical electrochemistry and is involved in applying that knowledge of SPM in a few different ways as an Applications Scientist: (1) Ongoing instrument and technique development, meaning new ways of obtaining nanoscale physical electrochemical information about materials and solution-solid interfaces; (2) Interacting with customers directly to help them achieve their desired research outcomes and advance nanotechnology and materials research - especially as these pertain to electrochemistry and related fields; (3) Generating interesting and scientifically-relevant images for the purpose of promoting SPM generally and educating others about the benefits and possibilities of SPM. During grad school, Nate also completed the GPMP certificate in management practice (via TMP) and often found himself applying that core business knowledge in all of the roles listed above. He believes it was really a rewarding position because he got to wear a lot of different hats and constantly collaborate with brilliant people on cutting edge research
