Monica Olvera de la Cruz (2010)

Monica Olvera de la Cruz is a soft-matter theorist, the Lawyer Taylor Professor of Materials Science and Engineering and Professor of Chemistry at Northwestern University.

Biography

Olvera de la Cruz obtained her B.A. in Physics from the UNAM, Mexico, in 1981, and her Ph.D. in Physics from Cambridge University, UK, in 1985. Olvera de la Cruz is a member of the U.S. National Academy of Sciences[1] and a fellow of the American Academy of Arts and Sciences as well as the American Physical Society.

She directed the Northwestern Materials Research Center[2] from 2006–2013, which she grew in research, funding level[3][4] and education, and expanded it to impact society beyond science and engineering by facilitating development of visionary outreach programs such as The Center for Scientific Studies in the Arts (NU-ACCESS). She is the Director of the Center for Computation and Theory of Soft Materials (CCTSM) at Northwestern University.

Research

Olvera de la Cruz has developed novel methods to analyze complex systems, and in particular molecular electrolytes. She explained the limitations associated with separating long DNA chains via gel electrophoresis dynamics,[5][6][7] which was of great importance to the Human Genome Project.

Monica Olvera de la Cruz discovered that counterions induce the precipitation of strongly charged polyelectrolytes by including electrostatic correlations in the analysis.[8][9][10][11] Her work provided a completely revised model of electrostatic effects in complex electrolytes[12] and in dielectrically heterogeneous media.[13]

She has described the emergence of shape and patterns in membranes and in multicomponent complex mixtures. She and her students and postdocs discovered that electrostatics leads to spontaneous symmetry breaking in ionic membranes such as viral capsids[14] (for which they were awarded the 2007 Cozarelli Prize),[15] and in fibers.[16][17]

They also demonstrated the spontaneous emergence of various regular and irregular polyhedral geometries in closed membranes with non-homogeneous elastic properties such as bacterial microcompartments, including carboxysomes,[18] via a mechanism that explains observed shapes in crystalline shells formed by more than one component such as archaea and organelle wall envelopes as well as in ionic vesicles.[19]

Awards and significant honors

Policy and public service

Olvera de la Cruz currently serves on the US Department of Energy's Basic Energy Sciences Advisory Committee, and the United States National Research Council. She has participated in many other committees including the National Research Council Board of Physics and Astronomy (2010-2015), Committee on Societal Benefits from Condensed Matter and Materials Research, Research at the Intersection of Physical and Life Sciences (RIPLS), the Solid State Science Committee and the Committee on Key Challenge Areas for Convergence and Health; from 2010-12 she chaired the Condensed Matter and Materials Research Committee. From 2005 to 2009 she was in the Mathematical and Physical Sciences Directorate Advisory Committee of the National Science Foundation, and chaired the Division of Materials Research Advisory Committee.

Personal life

Olvera de la Cruz and her husband Michael J. Bedzyk have a daughter, Ana Jimena Pavlovitch-Bedzyk.
