Charles K. Etner Early Career Assistant Professor · Computer Science and Engineering · Pennsylvania State University (2022.8 --)
Postdoc Researcher · SysML Team · Meta AI Research (2021.8 -- 2022.8)
I am a tenure-track assistant professor in the
Computer Science and Engineering Department at
Pennsylvania State University. Prior to joining PSU, I did a one-year postdoc at
Meta AI Research's
SysML Team. I did my Ph.D. at
Carnegie Mellon University, under the advisement of Professor
Brandon Lucia.
My research interest lies in
systems for privacy-preserving machine learning in the broadest sense. I am interested in studying the privacy implications of modern ML systems and developing algorithm/system/hardware solutions for privacy-preserving ML training and inference. In the past, I've also worked on systems for ML, ML and sustainability, and batteryless energy-harvesting devices.
If you are interested in working with me, please send me an email with:
(1) your interested research area (with respect to my research interest), (2) at least one of my publication you read and want to build upon, and (3) your relevant background experiences (e.g., courses, projects, publication experiences). If these are not provided explicitly, I will not respond to your email.
I am also an amateur webtoonist. Check out
my work if you know Korean. Otherwise, do not bother.
My pronouns are: he/his/him.
