An academic correspondent of the Casualty Actuarial Society. he teaches many of the upperlevel math classes at Northwestern.
Courses Calculus II
Calculus II (4 credits) A study of transcendental functions, techniques of integration, improper integration, sequences, series, polar coordinates and conic sections. Prerequisite: C or better in MAT112 or permission of instructor.  Advanced Statistical Methods
Advanced Statistical Methods (3 credits, alternate years, consult department) Further topics in probability and statistics selected from: multiple regression, ANOVA, nonlinear regression, covariance, collinearity, time series and autocorrelation. Prerequisite: C or better in MAT116 or 117 or permission of instructor.  Differential Equations
Differential Equations (3 credits) A study of the elementary theory, methods of solution, and applications of differential equations, which may include topics such as first order ordinary differential equations, linear equations with constant coefficients, series solutions, variation of parameters, Laplace Transforms, linear systems, partial differential equations, and Fourier Series. Prerequisite: C or better in MAT211 or permission of department chair.  Probability and Statistics I
Probability and Statistics I (3 credits, alternate years, consult department) A postcalculus course in probability and statistics, which develops the theory of discrete and continuous distributions, expected value, random variables and inferential statistics. Prerequisites: C or better in MAT116 or 117, 180, 211 or permission of instructor.  Probability and Statistics II
Probability and Statistics II (3 credits, alternate years, consult department) A continuation of Probability and Statistics I. Emphasis will be placed on functions of random variables and sampling distributions. Prerequisite: MAT316.  Actuarial Exam Review
Actuarial Exam Review (1 credit) This course is a comprehensive review of all materials for SOA/CAS exams. The course is tailored to the specific exam the student is planning on taking. Prerequisite: permission of chair of department.
