Dr. Ahmad was born and brought up in Bhadrak, Odisha. He did his B.Sc. from Bhadrak College and received his M.Sc. in Mathematics from Utkal University. Further, he received his M.Phil. from Ravenshaw University. He was awarded the Ph.D. degree in Mathematics from IIT Guwahati in 2008 with the help of GATE and SRF from CSIR. His thesis was concerned with “Pseudosepectra of Matrix pencils and their Applications in Perturbation Analysis of Eigenvalues and Eigendecompositions”. After his thesis submission, he joined SERC, IISc. Bangalore as a Research Associate on 2nd January 2008. One year after his research at IISc, he received an NBHM Post Doctoral fellowship funded by DAE and German Post Doctoral Fellowship BAT IIa. So he accepted German Fellowship and visited to the Institut für Mathematik, Universität Berlin, Germany in 2nd February 2009 as a Post Doctoral Fellow and then in Dec. 2009, he returned to IIT Indore and acted as Assistant Professor at the Discipline of Mathematics and in 2016, he became Associate professor at IIT Indore. He has served as faculty coordinator during 2010-2012 and served as Head of the Department during 2016-2018. His research interest lies inside Numerical Linear Algebra, Quaternion Linear Algebra, Matrix polynomial and Multiparameter eigenvalue problems, and various Inverse Eigenvalue Problems. He is actively working on different projects funded by the DST Govt of India. He has also visited various International Institutes on various programs under different Schemes of SERB. He has been actively involved in organising International conferences, conducting various workshops under GIAN and QIP.
