Research

research overview

  • Dr. Onyejekwe's research involves using multivariate regression models to estimate glacier changes as a means of explaining mountain glacier recession due to increased global temperatures. His model also predicts the location of glacier terminus over time, based on observed climate factors. Further, Dr Onyejekwe's research implemented a novel approach for noise reduction in signals corrupted with both gaussian and correlated noise via multi-scale kernel regression in conjunction with matched filtering. He then selected the bandwidth that yielded the highest Signal to Noise Ratio in order to estimate the unknown underlying signal. Dr. Onyejekwe also helped Burgio Enterprises Ltd; an Industry-Healthcare-Government-International research agency contribute to the company's first research finding on Degenerative Disc Disease in the Active Military Special Forces using a computerized data processing system to conduct a quadruple blind-study.

Teaching

courses taught

  • MATH 1012 - Quantitative Reasoning and Mathematical Skills
    Primary Instructor - Fall 2018
    Promotes mathematical literacy among liberal arts students. Teaches basic mathematics, logic, and problem-solving skills in the context of higher level mathematics, science, technology, and/or society. This is not a traditional math class, but is designed to stimulate interest in and appreciation of mathematics and quantitative reasoning as valuable tools for comprehending the world in which we live. Degree credit not granted for this course and MATH 1112.
  • MATH 2510 - Introduction to Statistics
    Primary Instructor - Fall 2018 / Spring 2019
    Elementary statistical measures. Introduces statistical distributions, statistical inference, hypothesis testing and linear regression. Department enforced prerequisite: two years of high school algebra.
  • MATH 3430 - Ordinary Differential Equations
    Primary Instructor - Spring 2019
    Involves an elementary systematic introduction to first-order scalar differential equations, nth order linear differential equations, and n-dimensional linear systems of first-order differential equations. Additional topics are chosen from equations with regular singular points, Laplace transforms, phase plane techniques, basic existence and uniqueness and numerical solutions. Formerly MATH 4430.
