Faces of Research - Profile Article

Soft materials are materials whose properties are determined by internal structures with dimensions between atomic sizes and macroscopic scales. They are characterized by energies that are typically comparable to kT. As a result, they have low elastic moduli, often ~1-10 Pascals. Typical soft materials include liquid crystals, polymers, colloidal suspensions and emulsion drops. These materials, unlike conventional simple liquids, are locally heterogeneous and can have broken symmetries that affect their physical properties. Hence, although they often exhibit liquid-like behavior, soft materials also often exhibit properties of solids. Our laboratory studies the physics of soft materials with a focus on the connection between microscopic order and macroscopic properties. The underlying theme is to pursue basic understanding and address fundamental questions. However, we also address applied problems and pursue industrial collaborations since many of the materials we study can be viewed as model systems for those that are often used in applications. Current projects include (i) studying the phase and non-equilibrium behavior and properties of dense microgel suspensions, (ii) understanding the consequences of confinement and curvature over the equilibrium states of ordered materials, which in many cases require the existence of topological defects in their ground states, and (iii) electrohydrodynamics of toroidal droplets and jets.

Facundo was born in Buenos Aires, Argentina. He received his MSc in Chemistry from the College of Exact and Natural Sciences, Buenos Aires University in 1995 and his PhD in Analytical Chemistry from the same University, in 1999.  In August 2000, he joined the research group of Prof. Richard N. Zare in the Department of Chemistry at Stanford University.  His work focused on several aspects of Hadamard transform time-of-flight mass spectrometry with an emphasis on coupling this technique to capillary-format separation methods.  In 2002, he joined the group of Prof. Vicki Wysocki in the Department of Chemistry at the University of Arizona, to develop novel tandem mass spectrometers for gas-phase peptide ion studies. In 2004 he joined the School of Chemistry and Biochemistry at the Georgia Institute of Technology where he currently holds the position of Vasser-Woolley Endowed Professor in Bioanalytical Chemistry and Associate Chair for Research and Graduate Training. He is the author of over 185 peer-reviewed publications and numerous invited presentations at national and international conferences. He has received several awards, including the NSF CAREER award, the CETL/BP Teaching award, the Ron A. Hites best paper award from the American Society for Mass Spectrometry, and the Beynon award from Rapid Communications in Mass Spectrometry, among others. He serves on the editorial board of The Analyst and as an Associate editor for the Journal of the American Society for Mass Spectrometry. His current research interests include the field of metabolomics and the development of new ionization, imaging, machine learning and ion mobility spectrometry tools for probing composition and structure in complex molecular mixtures. In his (limited) free time, Facundo enjoys a number of activities that include camping with his family, rock climbing, paddling, archery, photography and ham radio. 

My work is on excitable media, complex systems, and pattern formation, using a combined approach of theory, experiments, and computer simulations.

Interested in: Complex Systems, Experimental physiology, Biophysics, High performance computing and GPU.

Fedorov's background is in thermal/fluid sciences, chemical reaction engineering as well as in applied mathematics. His laboratory works at the intersection between mechanical and chemical engineering and solid state physics and analytical chemistry with the focus on portable/ distributed power generation with synergetic CO₂ capture; thermal management of high power dissipation devices and electronics cooling; special surfaces and nanostructured interfaces for catalysis, heat and moisture management; and development of novel bioanalytical instrumentation and chemical sensors. Fedorov joined Georgia Tech in 2000 as an assistant professor after finishing his postdoctoral work at Purdue University.

Christoph Fahrni earned a master’s degree in chemistry from the Federal Institute of Technology (ETH, Switzerland) and a Ph.D. degree in chemistry from the University of Basel (Switzerland). After working as a postdoctoral fellow at Northwestern University (Evanston, IL), he joined the School of Chemistry and Biochemistry at the Georgia Institute of Technology in 1999.

Prof. Ethier was originally trained as a mechanical engineer, receiving his Ph.D. from MIT in 1986 working in the lab of Roger D. Kamm. He then joined the University of Toronto, where he was a Professor of Bioengineering, Mechanical Engineering and Ophthalmology, and latterly the Director of the Institute of Biomaterials and Biomedical Engineering. Prior to joining Georgia Tech/Emory, Professor Ethier was the Head of the Department of Bioengineering at Imperial College, London from 2007-12. 

His research is in the biomechanics of cells and whole organs. His specific research topics include glaucoma (biomechanics of aqueous humour drainage in the normal and glaucomatous eye, and the mechanical and cellular response of optic nerve tissues to intraocular pressure), study of hemodynamic basis of arterial disease.
