MATH 305 - MATHEMATICAL MODELING: PROBABILISTIC MODELS


This course is part of a NSF funded interdisciplinary initiative to increase the mathematical training of undergraduates in the biological sciences as well as the knowledge of biomathematics
of mathematics majors, by exposing both to biological applications of mathematics and to modeling.   In addition to strengthening the undergraduate mathematics curriculum for biology majors, the program will establish a year long research experience in mathematical biology for small groups (teams) of undergraduates.   See UBM program announcement.

Students who take this course will be given priority in the selection of students to participate in the undergraduate research projects in mathematical biology during the summer of 2008.

COURSE DESCRIPTION:
                  
The course will cover basic techniques of probabilistic modeling.  Models drawn from mathematical biology will be used as "case studies" to motivate and illustrate the mathematical methods as well as to introduce classical areas of mathematical biology such as population genetics and evolution. The class will present an introduction to probability theory and stochastic processes, with particular focus on Markov models. Other topics will include evolutionary game theory, neural networks and maximum likelihood estimation. The class will include a computer laboratory that will teach the basics of programming in the statistical software R and provide computational tools for simulating and fitting probabilistic models including simulating stochastic processes, maximum likelihood estimation and Monte Carlo simulation.
             

TEXTBOOKS:

Due to the variety of topics to be covered in this course, instead of a single textbook, we will use handouts compiled from relevant sources in different areas.
