BioFringer's research focuses on the development and application of numerical models and high-performance computational techniques to the study of fundamental processes that influence the dynamics of the coastal ocean, rivers, lakes, and estuaries.
Director of PBL Lab
BioDr. Renate Fruchter is the founding director of the Project Based Learning Laboratory (PBL Lab), lecturer in the Department of Civil and Environmental Engineering, and Senior Research Engineer thrust leader of “Collaboration Technologies” at the Center for Integrated Facilities Engineering (CIFE), at Stanford. She received her Civil Engineering Diploma from the Institute for Civil Engineering, Bucharest, Romania. She received her M.Sc. and Ph.D. from the Technion – Israel Institute of Technology. Her R&D focuses on collaboration technologies in support of cross-disciplinary, geographically distributed teamwork in education and corporate settings. Over the years her research team developed and deployed innovative collaboration technologies for virtual team building, synchronous and asynchronous knowledge capture, sharing and re-use, project memory, corporate memory, and mobile solutions for global teamwork and e-Learning. She is a designer of physical and virtual interactive learning and workspaces. She studies the relation between technology-people-place-process. These studies focus on the impact of technology on learning, engagement, knowledge work productivity, emergent work practices and processes, team dynamics, and assessment. She is the developer of the innovative "Architecture, Engineering, Construction (AEC) Global Teamwork" course launched in 1993 engaging university and industry partners worldwide. Her latest projects focus on: (1) big data analytics and visualization towards harmonizing occupant well-being and building sustainable performance; and (2) accelerating creativity and engagement in global teamwork through VR, AI, and parametric modeling.

BioThe processing of complex liquids (polymers, suspensions, emulsions, biological fluids) alters their microstructure through orientation and deformation of their constitutive elements. In the case of polymeric liquids, it is of interest to obtain in situ measurements of segmental orientation and optical methods have proven to be an excellent means of acquiring this information. Research in our laboratory has resulted in a number of techniques in optical rheometry such as high-speed polarimetry (birefringence and dichroism) and various microscopy methods (fluorescence, phase contrast, and atomic force microscopy).
The microstructure of polymeric and other complex materials also cause them to have interesting physical properties and respond to different flow conditions in unusual manners. In our laboratory, we are equipped with instruments that are able to characterize these materials such as shear rheometer, capillary break up extensional rheometer, and 2D extensional rheometer. Then, the response of these materials to different flow conditions can be visualized and analyzed in detail using high speed imaging devices at up to 2,000 frames per second.
There are numerous processes encountered in nature and industry where the deformation of fluid-fluid interfaces is of central importance. Examples from nature include deformation of the red blood cell in small capillaries, cell division and structure and composition of the tear film. Industrial applications include the processing of emulsions and foams, and the atomization of droplets in ink-jet printing. In our laboratory, fundamental research is in progress to understand the orientation and deformation of monolayers at the molecular level. These experiments employ state of the art optical methods such as polarization modulated dichroism, fluorescence microscopy, and Brewster angle microscopy to obtain in situ measurements of polymer films and small molecule amphiphile monolayers subject to flow. Langmuir troughs are used as the experimental platform so that the thermodynamic state of the monolayers can be systematically controlled. For the first time, well characterized, homogeneous surface flows have been developed, and real time measurements of molecular and microdomain orientation have been obtained. These microstructural experiments are complemented by measurements of the macroscopic, mechanical properties of the films.
