Lance R. Collins
Professor Lance R. Collins is the Joseph Silbert Dean of Engineering at Cornell University. Prior to that he served as the S. C. Thomas Sze Director of the Sibley School of Mechanical & Aerospace Engineering from 2005-2010, and he was Director of Graduate Studies for Aerospace Engineering 2003-2005. Collins joined Cornell in 2002, following 11 years as Assistant Professor, Associate Professor and Professor of Chemical Engineering at Pennsylvania State University. From 1999 until his departure, he also held a joint appointment in the Mechanical & Nuclear Engineering Department at Penn State, and in 1998 he was a visiting scientist at the Laboratoire de Combustion et Systémes Réactifs (a National Center for Scientific Research laboratory in Orleans, France) and at Los Alamos National Laboratory.
Professor Collins' research combines simulation and theory to investigate a broad range of turbulent flow processes, including: (i) turbulent coagulation of aerosol particles (with applications to cloud processes and global climate modeling; (ii) experimental and numerical investigation of Lagrangian statistics in turbulent flows; (iii) mixing and chemical reaction in turbulent flames; (iv) turbulent breakup of microstructures (e.g., drops, polymers and red blood cells); (v) drag reduction due to polymer additives. A unifying theme is the importance of small-scale (micro-turbulence) transport to these phenomena. A second focus is on developing a new class of turbulence models that are capable of describing micro-turbulence processes.
