The Myth of Hierarchy in Bacterial Evolution

25 Mayo 2009 - 16:30
Lugar: 
Auditorio Dr. Guillermo Soberón del CCG
Expositor: 
Jeffrey Lawrence
Institución: 
Department of Biological Sciences. University of Pittsburgh. Pittsburgh, PA. USA.

El Dr. Jeffrey Lawrence trabaja en el departamento de Ciencias Biológicas de la Universidad de Pittsburgh, Pensilvania. Su investigación está dirigida a elucidar la evolución de genomas bacterianos, incluyendo su tamaño, composición, variabilidad y organización. Uno de sus objetivos es comprender como se diferencian
las especies, entendiendo los procesos evolutivos que causan las diferencias entre los genomas.

Sus líneas de investigación se enfocan en preguntas como: ¿Qué controla la tasa de transferencia horizontal?, ¿Cómo afecta la transferencia horizontal a la especiación?, ¿Cuáles son las restricciones sobre el tamaño de genoma en bacterias?, entre otras.
