## Faculty Research

Dr. Akinsete’s research interests are in stochastic processes, applied probability, and distribution functions. He is currently interested in generating statistical distributions and their applications to real-life data. His other areas of research focuses on queuing networks, and the statistical analyses of sports data.

Dr. Al-Aqtash’s research focuses on generating new families of T-X{Y} distributions by combining two existing distributions using a suitable link transformation, studying their mathematical properties and application to different real life phenomena. Other research interests include pattern recognition, data mining, time series, and regression modelling.

in developing and analyzing experimental designs to elicit survey data when the question(s) are particularly sensitive and, possibly, responses to such questions might not be truthful. His other areas of research focuses are applied probability and regression modelling.

Dr. Karna’s research interests are in Boundary Value Problems for Ordinary Differential Equations and Dynamical Equations. Currently, he is involved in finding positive solution(s) for multipoint boundary value problems using different fixed point theorems, comparing smallest eigenvalues for mulitipoint boundary value problems, and characterizing the first extremal point. He is also working on these problems on Time Scales (A Time Scale is a closed subset of the reals).

Dr. Lawrence’s research interests include calculus and analysis on time scales. This field generalizes discrete mathematics and continuous mathematics into a single system. Dr. Lawrence also heads the Marshall University Differential Analyzer Lab. This lab builds differential analyzers, which are analog machines for solving differential equations, and uses them to study differential equations and time scales calculus.

Dr. Mummert’s research interests are in Epidemiological and Ecological Modeling (Mathematical Biology) and Dynamical Systems. Currently, she is involved in studying the inverse problem of recovering the time-dependent transmission rate of an epidemiological model given incidence data in stochastic differential equations, the prairie ecoregion, questions around fresh drinking water in Iowa and WV, and using dynamical systems tools to understand mathematical biology models.

Dr. Mummert’s research is in mathematical logic, particularly in reverse mathematics, an area of logic seeks to determine which axioms are necessary to prove well-known theorems of mathematics. His reverse mathematics research has focused on principles from topology, choice principles, and countable combinatorics. He has also published papers in pure topology, and has mentored student research in logic, real analysis, and latin squares.

Dr. Sarra is an active researcher in numerical analysis. His research is with high-order methods for the numerical solution of partial differential equations (PDEs). The methods include radial basis function methods (RBFs) and pseudospectral methods. He is also involved with post-processing methods that reduce or eliminate the Gibbs phenomenon.
