Gijo Augustin
Gijo Augustin received a B.Sc. in electronics from Mahathma Gandhi University, India in 2000; a M.Sc. in industrial electronics from Bharathidasan University, India in 2002; and a Ph.D. in microwave engineering from Cochin University of Science and Technology (CUSAT), India in 2009. He was a guest lecturer in electronics from 2003-2004 with the College of Applied Science, India. In 2004, he joined the Center for Research in Electromagnetics and Antennas (CUSAT) as a research scholar. He received research training from the Royal Military College of Canada as a research assistant in 2008. He was with the Department of Electrical Communication Engineering, Indian Institute of Science, from 2009 to 2011, as a research associate; he was involved in the development of ultrawideband antennas for microwave imaging systems. Since 2011, he has been a postdoctoral researcher with the National Institute of Scientific Research (INRS), Montreal, Canada. He has been actively involved in the analysis, design, fabrication, and testing of ultrawideband antennas, circular polarized ring array antennas, dual polarized multiple-input-multiple-output (MIMO) antennas, and metamaterial-based high gain antennas for advanced wireless communication systems. He has designed and developed a number of electronically reconfigurable ultrawideband antennas for next generation cognitive radio systems. He also serves INRS as an antenna laboratory supervisor and provides training for new international interns, masters, and Ph.D. students. He is also a committee member for doctoral exams of PhD students at INRS. Dr. Augustin has authored and coauthored more than 50 research papers in peer-reviewed journals and in national/international conference proceedings. Dr. Augustin has received various awards and recognitions, including senior research fellowship from the Council of Scientific and Industrial Research (CSIR), Government of India (2007); the Young Scientist Award from the International Union of Radio Science (URSI), during the general assembly held at Chicago, IL, USA (2008); research associateship, Indian Institute of Science, India (2009); DS Kothari postdoctoral fellowship, University Grants Commission (UGC), government of India (2010); Fast Track Scheme for Young Scientists, Department of Science and Technology(DST), government of India (2011); and FQRNT postdoctoral fellowship from government of Canada (2011). He is a member of IEEE and serves as a reviewer of the IEEE Transactions on Antennas and Propagation and IEEE Antennas and Wireless Propagation Letters.
