Description:About the Seminar\n\nBacteria\, insects and fish that thrive at
  subfreezing temperatures produce proteins that bind to ice and manage its
  formation and growth. Ice binding proteins include antifreeze proteins an
 d ice-nucleating proteins. The latter are the most efficient ice nucleator
 s found in Nature. Many questions remain on how do these proteins recogniz
 e or nucleate ice\, what drives their selectivity and binding to ice\, and
  how does the size and aggregation of the proteins modulate their function
 . In this presentation\, I will discuss our recent work addressing these q
 uestions using molecular simulations and theory\, with particular focus on
  elucidating what intermolecular interactions and chemical motifs make the
 se proteins so efficient at their function\, to resolve the apparent parad
 ox that the same structures can promote and prevent ice formation\, and to
  draw general principles that can be used for the design of synthetic alte
 rnatives for control of ice formation and recrystallization.\n\nAbout the 
 Speaker\n\nValeria Molinero is the Jack and Peg Simons Endowed Professor o
 f Theoretical Chemistry and Director of the Henry Eying Center for Theoret
 ical Chemistry at The University of Utah\, where she studies the interplay
  between microscopic structure\, dynamics\, and phase transformations in m
 aterials. The modeling of water\, its anomalies and phase transitions\, ha
 ve been a focus of her research in the last years. Molinero’s contributi
 ons have been recognized with the Helmholtz Award\, Beckman Young Investig
 ator Award\, Myriad Award\, and Camille and Henry Dreyfus Teacher-Scholar 
 Award. 4:00 pm
