Minje Kim, Ph.D.

Bio: Minje Kim is an assistant professor in the Dept. of Intelligent Systems Engineering at Indiana University, where he leads his research group, Signals and AI Group in Engineering (SAIGE). He is also an Amazon Visiting Academic, consulting for Amazon Lab126. At IU, he is affiliated with various programs and labs such as Data ScienceCognitive ScienceDept. of Statistics, Center for Machine Learning, and Crisis Technologies Innovation Lab. He earned his Ph.D. in the Dept. of Computer Science at the University of Illinois at Urbana-Champaign. Before joining UIUC, He worked as a researcher at ETRI, a national lab in Korea, from 2006 to 2011. Before then, he received his Master’s and Bachelor’s degrees in the Department of Computer Science and Engineering at POSTECH (Summa Cum Laude) and in the Division of Information and Computer Engineering at Ajou University (with honor) in 2006 and 2004, respectively. During his career as a researcher, he has focused on developing machine learning models for audio signal processing applications. He is a recipient of various awards including NSF Career Award (2021), IU Trustees Teaching Award (2021), IEEE SPS Best Paper Award (2020), Google and Starkey’s grants for outstanding student papers in ICASSP 2013 and 2014, respectively, and Richard T. Cheng Endowed Fellowship from UIUC in 2011. He is an IEEE Senior Member and also a member of the IEEE Audio and Acoustic Signal Processing Technical Committee (2018-2023). He is serving as an Associate Editor for EURASIP Journal of Audio, Speech, and Music Processing, and as a Consulting Associate Editor for IEEE Open Journal of Signal Processing. He is also a reviewer, program committee member, or area chair for the major machine learning and signal processing venues, such as NeurIPS, ICML, AAAI, IJCAI, ICLR, ICASSP, Interspeech, ISMIR, IEEE T-ASLP, IEEE SPL, etc. He is on more than 50 patents as an inventor. 

Ph.D. Candidates

Sunwoo Kim

Bio: I am a PhD student studying in ISE. Before IU, I lived in Singapore and then studied Physics at UIUC. Currently, my research interests are in end-to-end systems, latent feature representations, and attention mechanisms. On my free time, I like to watch TV (too much), read books (epics), play board games, and go out to eat. I love meeting people and doing things, have nice conversations so please don’t hesitate to ask. 🙂

Aswin Sivaraman

Bio: I am a PhD student at Indiana University (IU) hailing from the Chicago suburbs. I received my BS in Electrical Engineering at the University of Illinois at Urbana-Champaign (UIUC). My research focuses on machine learning applications to music and speech processing applications, addressing tasks like noise reduction, dereverberation, style transfer, and diarization. Using deep learning approaches, I incorporate prior knowledge about digital audio and digital signal processing in order to compress neural networks or to boost model efficiency.

Darius Petermann

Bio: I am a PhD student as part of the ISE department. I am first and foremost passionate about the branch of machine learning applied to traditional audio signal processing problems. Pursuing my undergraduate and graduate studies in the field of Music Technology has led me to focus my research on audio signals. The bulk of my work has been on audio source separation, content analysis, and information retrieval. I am interested in investigating the design and research of new autonomous machine audition models, including but not limited to speech enhancement and audio source separation ones. With my background in audio engineering and auditory perception, I aspire to bring meaningful contributions to the understanding of sound, from machine listening related problems to their application toward novel audio processing tools. On my free time, I enjoy bowling as well as spending time with my dog.
