* Research Interests* – I am interested in problems in Real Analysis that provide insight into the highly unintuitive nature of the actually infinite. I worked on problems related to Cantor-type sets on the real line, finding Hausdorff dimensions and measures of such sets. I am also interested in understanding the changes in the wider historical and philosophical views of the infinite that eventually lead to the legitimization of the use of the actually infinite in mathematics.

* Teaching Interests – *I have implemented new technology in our introductory courses in Statistics and Linear Algebra. I was in charge of recreating our course in History of mathematics with a broader philosophical perspective to satisfy the World Views of Knowing Liberal learning requirement. I have guided several capstone projects in the areas of Number theory and Real analysis. I am teaching all my courses as discovery based, problem solving courses in the Hungarian tradition. Courses offered regularly include Calculus and courses in Real analysis including upper level seminars and Independent Research.

## Emeritus Faculty

**Mike Iannone**

Professor (1968-2012), Ed.D., Rutgers University

** Research Interests** – Most recently Dr. I, as he is known to his students, has devoted much of his work toward using technology in the classroom. A recipient of a Texas Instruments grant, he has worked with many of the top educators in the country on TI’s latest handheld computing device the TI-Nspire. He has incorporated the use of this technology into many of the classes he teaches here at the college. Additionally he has shared a number of the Nspire activities he has developed on TI’s educational website.

** Teaching Interests** – In his long tenure here at the college Dr I served as chair of the department for 14 years. He taught many of the offerings of the department and was the department’s first recipient of the math club’s Teacher of the Year award. For the past few years though, he has concentrated on teaching mathematics courses for elementary majors and statistics courses in which he utilizes technology as noted above.
