Dr. A. Sairam Kaliraj earned his doctorate degree from the Indian Institute of Technology Madras in 2014. His Ph.D thesis entitled “Geometric properties and characterizations of univalent harmonic mappings” was written under the supervision of Professor S. Ponnusamy, IIT Madras. He continued his research work as a Visiting Scientist (June 2014 – Oct. 2015) in the Indian Statistical Institute Chennai Centre. The National Board for Higher Mathematics, Department of Atomic Energy, awarded him the NBHM Postdoctoral Fellowship in 2015. With this fellowship, he carried out his postdoctoral research work at ISI Chennai Centre (Nov.2015 – Oct. 2017). Presently, he is an Assistant Professor in the Department of Mathematics at IIT Ropar.
