Lab Director Biography

Josiah Hester holds the Allchin Chair and is Associate Professor of Interactive Computing and Computer Science at Georgia Tech. Josiah was previously at Northwestern as an Assistant Professor. He works in intermittent computing and battery-free embedded computing systems. He applies his work to health wearables, interactive devices, and large-scale sensing for sustainability and conservation, supported by multiple grants from the NSF, NIH, and DARPA. He was named a Sloan Fellow in Computer Science and won his NSF CAREER in 2022. He was named one of Popular Science’s Brilliant Ten, won the American Indian Science and Engineering Society Most Promising Scientist/Engineer Award, and the 3M Non-tenured Faculty Award in 2021. His work has received six Best Paper type Awards and seven Best Presentation type Awards, and featured in the Wall Street Journal, Scientific American, BBC, Popular Science, Communications of the ACM, and the Guinness Book of World Records, among many others.

Research Overview

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?

• Do you have serious hardware hacking skills? Are you a software guru?
• Maybe you are interested in handling the massive amounts of lossy data these systems gather in an elegant way?
• Perchance you think that all of this falls apart unless we study the human factors, and the sociological impact of trillions of always on devices interacting with us?
• Or maybe you just really like to build things and see those things have an impact.

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 Georgia Tech’s College of Computing, and we can talk about working together. If you are already at Georgia Tech 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.
