Studying the microscopic world of bacteria, professor José Onuchic determined that
bacteria colonies rely on principles of game theory to make complex calculations under
difficult conditions. Onuchic, the co-director of the Center for Theoretical Biological
Physics at the University of California, San Diego, will present “How Bacteria Decide
Their Fate in Adverse Times” as part of the 2010 Tenneco Distinguished Lecturer Series
at the University of Houston.
The free, public event takes place at 5:30 p.m., Monday, Nov. 1 in the Shamrock Room
at the Hilton University of Houston. The UH College of Liberal Arts and Social Sciences,
the department of history, the Texas Center for Superconductivity (TcSUH) and the
department of physics welcome Onuchic to the Tenneco Lecture Series.
“Dr. Onuchic will detail his research in exploring game theory on the smallest scale,”
said UH physics professor Margaret Cheung. “We’re honored to host him.”
Researchers rely on game theory to mathematically capture behavior in strategic situations
in which the final outcome is determined through the actions of several subjects.
The theory was developed to analyze competitions in which one subject benefits at
another's expense.
"We have shown how the bacteria do this complex calculation according to well-defined
principles,” Onuchic explained. “We learned a simple rule: Anyone who needs to make
a decision under pressure in life, especially if it is a possible death decision,
will take its time. She or he will review the trends of change, will render all possible
chances and risks, and only then react.”
A member of the National Academy of Sciences, Onuchic’s current research interests
center on theoretical and computational methods for molecular biophysics and chemical
reactions in condensed matter.
Previous research demonstrated that bacteria live in large colonies that may reach
up to 100 times the number of people on Earth. Onuchic’s latest research shows how,
under adverse conditions, the bacteria in a colony communicate via chemical messages
and perform a sophisticated decision-making process by using a specialized network
of genes and proteins. This complex network enables the bacteria to perform complex
calculations in order to assess the pros and cons of the different choices guided
by the new principles of game theory.
Inaugurated in 1986, the Tenneco Lecture Series provides an opportunity for Houston
professionals, community leaders and others to consider historical and social perspectives
directly related to the decisions they make. The series is made possible by grants
from Tenneco Inc. and the National Endowment for the Humanities.
