Extn: 396


Dr.S.Sophia working as an Assistant Professor, in the Department of Mathematics  has done her doctorate in the field of Stochastic Processes.

She  received the Bachelors degree in Mathematics from Auxillium College, Vellore and M.Sc. (Mathematics) from St. Joseph’s College, Trichy. She worked as a part time lecturer in ICL College, Mumbai for two years. Later she pursued her Ph.D. from Anna University, Chennai.

Her area of specialization is Stochastic processes and its applications, in particular Queueing theory. Her current interests relate to catastrophe models in queueing systems. Her main research activity is in Tandem Fluid Queue models with input controlled by Exponential Timer. She has 5 papers published in various international journals and conferences. For a short period she worked in Stella Maris College, Chennai. She joined SSNCE in July 2010 as an Assistant Professor.
