CSS Biography

Chandra Sekhar Seelamantula (Senior Member, IEEE) received the Bachelor of Engineering degree with Prof. K. K. Nair Gold Medal and Best Thesis Award in Electronics and Communication Engineering from Osmania University College of Engineering, Hyderabad, India, in 1999 and the Ph.D. degree, with IBM India Research Lab Fellowship, from the Department of Electrical Communication Engineering, Indian Institute of Science (IISc), Bangalore, India, in 2005. During April 2005–March 2006, he worked as a Technology Consultant for ESQUBE Communication Solutions Private Limited, Bangalore, India, where he developed proprietary audio coding solutions. During April 2006–July 2009, he was a Postdoctoral Fellow with Biomedical Imaging Group, École Polytechnique Fédérale de Lausanne, Lausanne, Switzerland, where he specialized in optical-coherence tomography, holography, splines, sparse signal processing, and sampling theories. In July 2009, he joined the Department of Electrical Engineering, IISc, where he is currently a Professor and directs research with Spectrum Lab. His lab works on cutting-edge topics in speech processing, image processing, compressed sensing, inverse problems in computational imaging, and machine learning. He served as an Adjunct Faculty with the Centre for Neuroscience, IISc. He was Vice-Chair (2013–2017) and Chair (2017–2021) of IEEE Signal Processing Society Bangalore Chapter, an Associate Editor for the IEEE SIGNAL PROCESSING LETTERS (2013–2017), an Associate Editor for the SPIE Journal of Electronic Imaging (2014–2018), a Senior Area Editor of the IEEE SIGNAL PROCESSING LETTERS (2017–2021), and an Associate Editor for the IEEE TRANSACTIONS ON IMAGE PROCESSING (2018-2022), an Area Chair for the IEEE International Conference on Acoustics, Speech, and Signal Processing 2020, and an elected member of IEEE Technical Committee on Computational Imaging (2020-2023). He served as the Session Chair and Special Session Organizer at several editions of premier international and national conferences -- notably, ICASSP (International Conference on Acoustics, Speech, and Signal Processing), ICIP (IEEE International Conference on Image Processing), ISBI (International Symposium on Biomedical Imaging), SampTA (Sampling Theory and Applications), DSP Conference (Digital Signal Processing conference), SPCOM (Signal Processing and Communications), and NCC (National Conference on Communications). He received the Outstanding Editorial Board Member award in the year 2022 for his service as Associate Editor of IEEE Transactions on Image Processing. He served on the Organizing Committee (Tutorials, Publicity, and Local Organization) of Interspeech 2018, IEEE International Symposium on Biomedical Imaging 2020, served as the General Chair of International Conference on Signal Processing and Communications 2020. He was the recipient of Prof. Priti Shankar Teaching Award from IISc, Digital Health Prize at National Bio-Entrepreneurship Competition (NBEC) 2018, the Grand Challenges Exploration – India (Round 5) Research Award funded by Bill and Melinda Gates Foundation and Biotechnology Industrial Research Assistance Council in 2020, and four Qualcomm Innovation Fellowship awards (joint recipient with Ph.D. students) during 2019-2022.
