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.
