Mohammod Ali

Biography

Dr. Mohammod Ali is a professor in the Department of Electrical Engineering at the University of South Carolina (USC). As of July 2019, he has been working as a Program Director at the National Science Foundation (NSF) under IPA (Intergovernmental Personnel Act) assignment in the Division of Electrical, Communications, and Cyber Systems for the Directorate of Engineering.

Prof. Ali received his B.Sc. in Electrical and Electronic Engineering from the Bangladesh University of Engineering and Technology, Dhaka in 1987. He received his M.A.Sc. and Ph.D. degrees in Electrical Engineering in 1994 and 1997, respectively from the University of Victoria, British Columbia, Canada.

Dr. Ali worked for Ericsson Inc. in Research Triangle Park, North Carolina from 1998-2001. He joined the University of South Carolina in August 2001. He spent a year on sabbatical in 2013-2014 at the Air Force Research Laboratory (AFRL) at the Wright Patterson Air Force Base (WPAFB), Ohio conducting research on conformal reconfigurable antennas. In the summers of 2010 and 2011 he was a Summer Faculty Fellow at the AFRL. Prof. Ali also held a visiting appointment at the Motorola Corporate EME Research Laboratory in Plantation, Florida in the summer of 2004.

He is the recipient of the 2003 National Science Foundation Faculty Career Award. Prof. Ali was the Technical program Co-Chair of the IEEE Antennas and Propagation Societys International Symposium in Charleston, SC in 2009. Prof. Ali was an Associate Editor for the journal IEEE Antennas and Wireless Propagation Letters from 2008-2013.

He has graduated 23 students (12 Ph.D.) and is the author/coauthor of over 190 publications and 8 granted US patents. His research has been funded by the Army Research Office (ARO), Air Force Research Laboratory (AFRL), Department of Energy (DOE), National Science Foundation (NSF), Office of Naval Research (ONR), the Boeing Company, and the Mobile Manufacturer’s Forum (MMF). His research interests include conformal antennas, meta-materials and metasurfaces, reconfigurable antennas, embedded smart antennas, wearable/implantable antennas, bio-electromagnetics, wireless power transfer, and wireless sensors for infrastructure health monitoring.

Research Interests

  • Conformal Antennas in Aerospace Applications – broadband, load bearing, reconfigurable antennas and phased arrays. 3D printing and additive manufacturing of antennas and RF structures.
  • Wireless power transfer and wireless sensing in infrastructure – wireless sensor design using RF/electromagnetic principles, such as interdigitated sensors for dielectrometry (cable insulation damage detection, moisture variation detection), and surface wave sensors for time frequency based reflectometry. Near and far field wireless power transfer for sensors in difficult to reach areas.
  • Antennas for Mobile Wireless Communications – Multiband or wideband antenna design for mobile wireless communications for handhelds, wearables, and base stations. Frequency and pattern reconfigurability, Multiple Input Multiple Output (MIMO), Specific Absorption Rate (SAR), platform integrated antennas.
  • Reconfigurable Antennas for mm-Wave – high performance phased array antennas for the handheld and wireless access points for 5G mm-Wave communications. Antenna design for Internet of Things (IoT).
  • Metamaterials and metasurfaces for Antennas and Signals – broadband metamaterials for conformal aircraft antennas, broadband absorption materials, cross-talk reduction in printed circuit boards. 

Education

  • Ph.D. Electrical Engineering, University of Victoria, BC, Canada, 1997
  • M.A.Sc. Electrical Engineering, University of Victoria, BC, Canada, 1994
  • B.Sc. Electrical and Electronic Engineering, Bangladesh University of Engineering and Technology (BUET), 1987
