  • Biographie

    Dr. Jayendiran Raja is a dyna­mic resear­cher with expe­rience in various fields of mecha­ni­cal engi­nee­ring. He is spe­cia­li­zed in com­pu­ta­tio­nal mecha­nics applied to mate­rial (smart com­po­sites, bio­lo­gi­cal soft tis­sues and bio­ma­te­rial) cha­rac­te­ri­za­tion. He holds a PhD in Smart com­po­sites mate­rial cha­rac­te­ri­za­tion (Indian Institute of Technology Madras, India, 2014), a Master in Computer Aided Design (Anna University, India, 2007), and a Bachelor in Mechanical Engineering (University of Madras, India, 2001). He has wor­ked in three world‐​class research ins­ti­tu­tions, name­ly, the Indian Institute of Technology Madras (Chennai, India), the University of Lorraine‐​LEMTA‐​CNRS (Nancy, France), the Texas A & M University (Doha, Qatar). He has 7 years of tea­ching expe­rience in Engineering col­leges in India.

    The topics of his research are Computational fluid dyna­mics ana­ly­sis of ascen­ding tho­ra­cic aneu­rysm (cur­rent post­doc at Ecole Nationale Superieure des Mines de Saint-´Etienne), Fluid‐​Structure Interaction of Elastic Shells for Aerospace and Biomedical Applications (Postdoc at Texas A&M University at Qatar), Constitutive mode­ling and expe­ri­men­tal cha­rac­te­ri­za­tion of pie­zoe­lec­tric mate­rials for ener­gy har­ves­ting appli­ca­tions (Postdoc at University of Lorraine‐​LEMTA‐​CNRS, France). During his PhD at Indian Institute of Technology Madras, India, he wor­ked on Theoretical and Experimental Investigations on Non‐​linear Behaviour of 1–3 Piezocomposites for bio­me­di­cal appli­ca­tions. Through this intense research acti­vi­ty, he has achie­ved a high‐​level mul­ti­dis­ci­pli­na­ry exper­tise in mate­rial and geo­me­tri­cal model­ling of smart com­po­sites and bio­ma­te­rials (such as Dacron, Shape Memory Alloy). Since the ear­ly stages of his career, Dr. Jayendiran Raja has been wor­king in mul­ti­dis­ci­pli­na­ry envi­ron­ments in close contact with high­ly repu­ted senior scien­tists and sur­geons.

    His research has rea­ched levels of excel­lence in all the acti­vi­ties he has been invol­ved, as confir­med by his publi­ca­tions record. Indeed he contri­bu­ted to 21 publi­ca­tions in inter­na­tio­nal jour­nals and 10 confe­rence pro­cee­dings, cove­ring very dif­ferent topics. This reveals flexi­bi­li­ty, adap­ta­bi­li­ty to new research sub­jects as well as good com­mu­ni­ca­tion skills. His work has been publi­shed in high qua­li­ty jour­nal such as Composites Part B, International Journal of Solid and Structures, Journal of Applied Physics, European Journal of Mechanics A/​ solids, Journal of fluids and struc­tures, Journal of Mechanical Behaviour of Biomedical mate­rials, Smart Materials and Structures etc. Very often in his career he has coor­di­na­ted to the research work of stu­dents. In these occa­sions, he sho­wed ini­tia­tive, inde­pendent thin­king and lea­der­ship. He is the reci­pient of Best PhD the­sis award for the the­sis “Theoretical and Experimental Investigations on Non‐​linear Behaviour of 1–3 Piezocomposites” from Indian Institute of Technology Madras, India. He recei­ved best pos­ter award for the paper “Finite ele­ment mode­ling and expe­ri­men­tal stu­dy on elec­tro­me­cha­ni­cal res­ponse of 1–3 pie­zo­com­po­sites”, 2nd International Conference on Advance Functional Materials, India.

    He has been invol­ved in pro­jects fun­ded by the Centre National de la Recherche Scientifique (CNRS), France, Qatar National Research Fund (QNRF), Qatar and Department of Materials Research Laboratory (DMRL), India acqui­ring abi­li­ty to plan the research acti­vi­ty and to work with strict dead­lines. Dr. Jayendiran Raja has also contri­bu­ted to the deve­lop­ment of an expe­ri­men­tal lab (Smart Material Characterization Lab) at Indian Institute of Technology Madras.
