Fractals and Chaos Simplified 
Fractals and Chaos Simplified for the Life
Sciences
 by Larry S. Liebovitch
 Oxford University Press, New York NY, 1998
 ISBN 0195120248
 This book explains the properties of fractals and chaos and illustrates
them with examples from biology and medicine. The aim is to provide
a basic understanding to people who are unfamiliar and/or afraid
of mathematics. However, enough mathematical detail is provided
so that biomedical scientists can learn how to use these new
methods in their own research. The material is presented one
concept at at time on facing pages, with text on the left page and
graphics on the right page. The graphics pages can be copied onto
transparencies to use to teach this material.

Fractal Analysis in the Social Sciences
 by Clifford T. Brown and Larry S. Liebovitch
 SAGE Publications, Thousand Oaks, CA, 91320
 ISBN: 9781412971652
 This primer uses straightforward language to give the reader stepbystep
instructions for identifying and analyzing fractal patterns and
the social process that create them. By making fractals
accessible to the social science students, this book has a
significant impact on the understanding of human behavior.
 Detailed examples help readers learn and understand the analytical methods
presented.
 Clear and logical explanations of fractals and their analysis enable the
instructor to easily teach and the student to easily learn the
material.

Current
Research 
Current Research Interests
The
analysis of complex systems that have many interacting parts.

PEOPLE: Models of Conflict
We are applying concepts from the dynamics of physical
systems to model the interactions between two or more people and
then, as part of a
team of social
scientists, using social psychology laboratory experiments to test the
predictions of those models. Liebovitch et al., 2008,
Physica
A387:63606378

GENES: Differentiation of Blood
Stem Cells
We are using mathematical
models of the interaction of genes (such as GATA1 and PU.1) to
predict how changes in the levels of signaling proteins and gene
expression lead to different cell fates from progenitor blood stem cells. These
predictions will be tested by experiments to be done at the Institute
for Stem Cell Research at the Helmholtz Center Munich, Germany.

DRUGS: Turning Deleterious Drug
Interactions Into Useful Multidrug Therapies
Drugs designed for a specific target are always found to have
multiple effects. We are exploring how to use computational methods
to predict which combinations of drugs, whose effects interfere with
each other, in just the right way, to produce more targeted results
with fewer side effects. Liebovitch et al., 2007,
Nonlinear
Biomedical Physics, 1:11..

EPIDEMICS: Spread of Infectious
Diseases
We are modeling the spatial and
temporal transmission of infectious agents through geographically
distributed "patches" of people. These models give insight
into how diseases spread in response to natural and human created
events. Rho et al., 2008,
Phys. Letts.
A372:50175025.

ECONOMICS: Econophysics
We are analyzing the prices of commodities from ancient
Babylon and medieval England to determine if ancient economies
functioned as supply and demand systems, like modern economies. The
challenge here is how to analyze time series data when there are
gaps of 70% to 95% in the data.
Europhysics Letters
90:18004.

ARCHEOLOGY: Movements of People
and the Spatial Distribution of their Artifacts
We are using new methods, based on fractals, to analyze and
understand the migration patterns of people and the spatial
distribution of their artifacts at archeological sites. Brown et al.,
2005, J. Archaeological
Method and Theory 12:3778.

Most things are made up of many pieces that interact strongly with
each other.
Yet much of science has tried to study
things by tearing them apart and studying only their tiny separate,
noninteracting pieces.
Here we will learn how the
science of "complexity" is able to help us see, analyze,
and understand complex entities in physics, chemistry, biology, and psychology.
Note: This course may serve as an
elective for psychology graduate students if it has been approved by
a student's advisor and committee; but it cannot be substituted for
a core course; it may only serve as an elective.
