This will be an ongoing web page in the area of undergraduate Real Analysis. I am a professor of mathematics at Saint Vincent College and chairman of the Mathematics Department. My main interest lies in the area of Real Analysis where I have published the following papers in The American Mathematical Monthly, Mathematics Magazine, and in The Real Analysis Exchange.
