Dr. Ma is currently a Professor with the Department of Electronic Engineering, CUHK. He was with the Department of Electrical Engineering and the Institute of Communications Engineering, National Tsing Hua University, Taiwan, as an Assistant Professor from Aug. 2005 to Aug. 2007. Prior to becoming a faculty, he held various research positions at McMaster University, Canada, CUHK, Hong Kong, and the University of Melbourne, Australia.

Dr. Ma is well recognized for his contributions to optimization in signal processing and communications, which led him to the escalation of the IEEE Fellow grade in 2017. Most recently, he also extended his research interest to the applications of optimization to areas such as remote sensing, data analytics and machine learning. His recent research activities can be categorized into two broad topics, namely, i) MIMO transceiver designs and interference management in wireless communications, and ii) structured matrix factorizations and their applications to hyperspectral remote sensing, blind source separation and machine learning.

Dr. Ma is active in the Signal Processing Society. He has rich experience in editorial service: Associate Editor, and then later, Senior Area Editor, of IEEE Transactions on Signal Processing (2007-2011 and 2016-2018, respectively); a Guest Editor of the IEEE Signal Processing Magazine Special Issue on "Convex Optimization for Signal Processing" in 2010; a Guest Editor of IEEE Journal on Selected Areas of Communications on the special issue of "Signal Processing Techniques for Wireless Physical Layer Security" in 2013; the Lead Guest Editor of the IEEE Signal Processing Magazine Special Issue on "Signal and Image Processing in Hyperspectral Remote Sensing" in 2014; an Associate Editor of IEEE Signal Processing Letters (2009-2012); and an Associate Editor of Signal Processing (2013-2018). He was a Technical Committee Member of the Signal Processing Theory and Methods (SPTM) Technical Committee, IEEE Signal Processing Society (2012-2017), and he is now a Technical Committee Member of Signal Processing for Communications and Networking (SPCOM) Technical Committee, IEEE Signal Processing Society (2015 - present). He served Technical Program Committees of numerous conferences. He was a Technical Program Co-Chair of SPAWC 2017 and a Special Session Co-Chair of SSP 2018.

Regarding awards and honors, Dr. Ma received a 2009 Exemplary Teaching Award given by the Faculty of Engineering, CUHK, the Research Excellence Award 2013-2014 by CUHK (only one awardee in each faculty), the 2015 IEEE Signal Processing Magazine Best Paper Award, and the 2016 IEEE Signal Processing Letters Best Paper Award. He is a co-receipent of a WHISPERS 2011 Best Paper Award. His students received ICASSP Best Student Paper Awards in 2011 and 2014, and one student was a finalist of the ICASSP 2017 Best Student Paper Contest. He has a paper that was named by Google Scholar as a Classic Paper; see here and here. He was escalated to the IEEE Fellow grade in 2017.
