research overview

  • I modeled a multi-level distribution of three dimensional arrays using a Bayesian approach assuming a separable covariance structure that is the sum of a set of Kronecker products. The goal was to find patterns in the covariance of the survey participants’ responses across quality measures and years to enhance public reporting and quality monitoring.

Teaching

courses taught

  • APPM 1350 - Calculus 1 for Engineers
    Primary Instructor - Fall 2020 / Spring 2022
    Topics in analytical geometry and calculus including limits, rates of change of functions, derivatives and integrals of algebraic and transcendental functions, applications of differentiations and integration. Students who have already earned college credit for calculus 1 are eligible to enroll in this course if they want to solidify their knowledge base in calculus 1. For more information about the math placement referred to in the "Enrollment Requirements", contact your academic advisor. Degree credit not granted for this course and APPM 1345 or ECON 1088 or MATH 1081 or MATH 1300 or MATH 1310 or MATH 1330.
  • APPM 2360 - Introduction to Differential Equations with Linear Algebra
    Primary Instructor - Fall 2023 / Spring 2024
    Introduces ordinary differential equations, systems of linear equations, matrices, determinants, vector spaces, linear transformations, and systems of linear differential equations. Credit not granted for this course and both MATH 2130 and MATH 3430.
  • APPM 3570 - Applied Probability
    Primary Instructor - Spring 2021 / Fall 2021 / Fall 2022 / Spring 2023
    Studies axioms, counting formulas, conditional probability, independence, random variables, continuous and discrete distribution, expectation, joint distributions, moment generating functions, law of large numbers and the central limit theorem. Degree credit not granted for this course and ECEN 3810 or MATH 4510. Same as STAT 3100.
  • MATH 4520 - Introduction to Mathematical Statistics
    Primary Instructor - Fall 2021 / Fall 2022 / Fall 2023
    Examines point and confidence interval estimation. Principles of maximum likelihood, sufficiency, and completeness: tests of simple and composite hypotheses, linear models, and multiple regression analysis if time permits. Analyzes various distribution-free methods. Same as MATH 5520 and STAT 4520 and STAT 5520.
  • STAT 3100 - Applied Probability
