HIGHLIGHTS of ACHIEVEMENTS and INTERESTS

Research (with references to articles further down)
I. American period (1981-1993) ( Drexel University (Pennsylvania), Census Bureau, Washington, DC, University of North Carolina at Chapel Hill, Clemson Universty (South Carolina), Loyola University (New Orleans)). Research in mathematical demography, (c1-c6), demo-economic modeling (e1-e2), matrix analysis (b1-b2), mathematical epidemiology (HIV/AIDS) (d1-d2).

II. French period (1993-present) (University of Pau). Move to France to work with a medical entomologist on the modeling of sleeping sickness (a10, b3-b7, b9). More work on HIV/AIDS modeling (d9, b8), matrix analysis (a9, a11), and classical analysis (a13).

This research has resulted in over 40 publications in international journals of mathematics, biomathematics, biology, epidemiology, demography, and economics/history (see list below).

III. Current/Recent activities and research
i. Organization of an international conference on The Role and Impact of Mathematics in Medicine held in Paris on 10-12, June 2010.
ii. Member of the French government program ARDIGRIP on “Avian influenza modeling”.

Editorial activities
 I am the Founding Editor in 1988 (and editor until 2002) of Mathematical Population Studies, an international journal of mathematical demography published by Taylor and Francis.

Teaching
Since 1981 I have taught in four American and French universities a broad range of applied math courses (calculus, applied statistics, modeling, operations research, matrix analysis).
I have practically not touched a piece of chalk in the last 10 years of my teaching. I use a video projector to project live, interactive lectures prepared with MathCad, a mathematical software designed for engineers but very well suited to teaching.
The problem with too much convenient technology is that students become passive in the learning process. This happens for example if one provides complete lecture notes, either as hard copies or on the Internet. In 2004 I therefore started experimenting with a concept that combines the benefits of new technologies with those that come in the process of writing down notes in long hand. I provide students in advance with lecture notes "full of holes" to be filled by hand during the lecture. This avoids the time-consuming task of writing down routine material. Having to write by hand focuses the mind and helps concentrate on the important stuff. Student feedback suggests that they like this compromise.
This approach is experimental and I would like to hear from anyone with any thoughts on the best ways to use new instructional technologies in the delivery of lectures. Click here to access more info and sample MathCad files. (MathCad needed on your computer).

CONSULTING
During Fall 1988 I worked with the New York State Department of Health (in Albany) on the modeling of the future course of AIDS in the state. I spent a day in Albany (September 20) during which I made a presentation for the state health authorities on my projections of AIDS in the state. I wrote a user-friendly computer software (HIVAIDS90) to forecast the number of AIDS cases. This model is described in M. Artzrouni (1990).
