Josiah Hester is an Assistant Professor of Computer Engineering at Northwestern University. Josiah joined Northwestern in 2017 after completing his Ph.D. in Computer Science at Clemson University. His work has received a Best Paper Award and Best Paper Nomination from ACM SenSys, the top conference on wireless sensors networks, and two Best Poster Awards. He was also named the Outstanding Ph.D. Student in Computer Science for 2016 by the School of Computing at Clemson University. He has served as a reviewer for many top venues, including ACM Transactions on Sensor Networks, ACM Transactions on Embedded Computing Systems, PACM IMWUT / UbiComp, IEEE Transactions on Mobile Computing. A Native Hawaiian, he is interested in increasing participation in STEM disciplines for Native and original peoples of the USA, especially at the graduate level.
We hold the vision that the untethered computing devices—wearables, implantables, energy harvesting sensors—hold significant promise for revolutionizing global scale applications across healthcare, environmental stewardship, infrastructure management, and space exploration.
Our research is concerned with the underlying computer systems principles, human factors, and behavioral issues that arise by bringing this vision to reality. We explore and develop radically new hardware designs, software techniques, tools, and programming abstractions so that developers can easily design, debug, and deploy intricate energy aware applications that work in spite of frequent power failures, constrained resources, and unpredictable conditions.
Research Approach: We build fully integrated, end-to-end computer systems to demonstrate the efficacy of the underlying scientific advancement we are concerned with. We run physical experiments to validate our hypothesis on hard benchmarks. We run user studies in the wild to test our sensing technologies, gathering quantitative and qualitative results that inform future work and guard against failures.
Our lab is always looking for highly motivated, extremely curious students, with interesting and diverse backgrounds. After reading some of our papers, and looking at some of our projects, where do you see yourself?
If you are any of these people, we might be interested in working with you as a graduate, or undergraduate student.
Before you contact us, It is highly recommended you read this advice , and this advice. Make sure to apply to Northwestern Engineering, and we can talk about working together. If you are already at Northwestern as an undergraduate or graduate student, email Prof Hester to schedule a time to talk in his office.
Prof Hester (a Native Hawaiian) is especially interested in engaging Native and Indigenous students and researchers in Computer Science and Engineering. Please reach out.
Our vision is that computational jewelry, in a form like a bracelet or pendant, will provide the properties essential for successful body-area mHealth networks.
