Purpose

The purpose of this not-for-profit site is to share public health concepts and methods in the following areas: (1) epidemiology and control of infectious diseases; (2) emergency preparedness and response; (3) epidemiologic methods and computing; (4) community and population health; (5) leadership and management; (6) systems science and health, and (7) some personal hobbies.  These topics are based on my experience, expertise, and interests.  In all these areas I am an enthusiastic student with much to discover and learn.
