Minseok Choi finished his Ph.D. at Korea Advanced Institute of Science and Technology under the guidance of Prof. Jaekyun Moon. He has been with Prof. Joon Kim (who is himself a WiDeS alumnus) as a post-doctoral research associate since he graduated. Dr. Choi is an expert on video caching-based distribution schemes, in particular femto-caching, and will strengthen the cluster of researchers at WiDeS working on this topic.

It was 10 years ago, January 2009, that the Wireless Devices and Systems (WiDeS) group was founded by Prof. Andy Molisch when he joined USC. Since then, the group has been on a remarkably successful trajectory. A few key statistics: more than 100 journal papers published in IEEE journals (plus many conference papers), multiple patents filed; results from the group successfully submitted to international standards; 10 PhD students graduated; and numerous prestigious awards collected by WiDeS members. The group has also established itself as an international meeting place: 10 PostDocs and visiting professors, and 10 visiting PhD students have been hosted. Looking forward to successful next 10 years!

As every year, WiDeS was represented at Globecom, traditionally the largest of the conferences in the communications area. This year, four papers were presented, covering the range from mm-wave channel measurements to machine learning to reduced-complexity MIMO receivers: "28 GHz Foliage Propagation Channel Measurements" (with the recently graduated Umit Bas as lead author), "Measurement Based Directional Modeling of Dynamic Human Body Shadowing at 28 GHz" (Thomas Choi lead author), "Multi-antenna FSR Receivers: Low Complexity, Non-coherent, Massive Antenna Receivers" (recently graduated Vishnu Ratnam as lead), and "Inferring Remote Channel State Information: Cramér-Rao Lower Bound and Deep Learning Implementation", a collaboration with Tsinghua University, with former visiting student (and now Tsinghua PostDoc) Zhiyuan Jiang as lead author.

WiDeS is among the pioneers applying machine learning to propagation channels. Recent contributions include predictions of dual-band channels, estimating channel states at remote base stations, and clustering. In August, WiDeS head Molisch gave an invited talk at the ITU workshop on Machine Learning; conference presentations at Milcom and Globecom are coming up.
