Autorenportrait

Valarmathi Sigamani got her PhD for her findings on numerical analysis of singular prturbation problems for third order ordinary differential equations. She had been working in Bishop Heber College, Tiruchirappalli for about 34 years and was the Head of the Department of Mathematics for fourteen years and retired as the Vice-Principal of the College.  She is an active researcher in the field of numerical analysis for singular perturbation problems for the past 23 years. She has guided eight students for their PhD and published many papers in reputed international journals. She has been refereeing for few SCI journals and doing joint research works with the great scientist Prof.John J.H. Miller, Professor, Institute for Numerical Computation and Analysis (INCA) Dublin, Ireland, for the past 16 years. She has edited books and participated in many BAIL (Boundary And Interior Layers) Conferences held once in two years at different places round the globe. She loves teaching.John J.H. Miller was graduated with a double moderatorship in Mathematics and Natural Sciences from Trinity College, Dublin having first studied modern languages and literature. Obtained a Ph.D. in numerical analysis at the Massachusetts Institute of Technology under the supervision of Professor Gilbert Strang. Now he is a Professor at Institute for Numerical Computation and Analysis (INCA) A96 N8K1.Dublin, Ireland. Prof. John Miller is a pioneer in the area of constructing robust computational techniques to solve singular perturbation problems arising from the study of Navier-Stokes Equations. He worked on the Fitted Operator Methods and Fitted Mesh Methods for certain classes of singular perturbation problems and the analysis of the convergence of these methods which are among the most cited and used works in the literature. Research Gate says that Prof. John Miller's score in Research Gate is higher than 92.5% of all Research Gate members scores.Shivaranjani Nagarajan is an Assistant Professor in the Department of Mathematics at the National Institute of Technology, Tiruchirappalli, Tamil Nadu. She did her doctoral studies on constructing numerical methods for singularly perturbed delay differential equations under the guidance of Dr. Valarmathi Sigamani. She secured the First rank in Bharathidasan University, Tamil Nadu in her Masters Programme. During her Doctoral studies, she received the prestigeous Inspire Fellowship from the Department of Science & Technology, Government of India. This fellowship is meant for the first rank holders to do their PhD if their research proposals also seem to be good. She has publications in reputed International journals. Her research interests include differential equations arising in mathematical biology and currently she is working on systems of singularly perturbed differential equations characterised by two singular perturbation parameters.   Parthiban Saminathan is an Assistant Professor of Mathematics at Bishop Heber College, Tiruchirappalli, Tamil Nadu. He completed his doctoral studies in numerical analysis of systems of parabolic delay differential equations under the guidance of Dr.V. Franklin, Assistant Professor, Department of Mathematics, Bishop Heber College. He is skilled in Data Science and handling data with R.  He is very much interested in developing codes animating simple mathematical concepts.
