Josh Goldberger received his B.S. in chemistry from The Ohio State University in 2001. He received his Ph.D. in chemistry from the University of California at Berkeley with Professor Peidong Yang in 2006, as an NSF graduate fellow. He then did his postdoctoral research with Professor Sam Stupp at Northwestern University as part of the Institute for BioNanotechnology in Medicine, as an NIH-NRSA postdoctoral fellow (2007-2010). He has received many awards, including an MRS Graduate Student Finalist Award in 2003, and an IUPAC Prize for Young Chemists in 2007. He joined the Ohio State Chemistry Department in August of 2010.
Dimensionally-Reduced Material "Allotropes" for Medicine and Energy
The major focus of our lab is to learn how to design new materials that synergistically unite and organize inorganic and organic components for applications in energy conversion and medicine. Similar to how carbon can be sculpted into low-dimensional allotropes such as fullerenes, nanotubes, and graphene, the major premise of our research program is that the framework connectivity of atoms for any crystalline solid can be constrained along specific axes to produce stable, single atom or polyhedron thick (<1 nm) dimensionally-reduced “allotropes” with transformative physical phenomena. Using a combination of synthesis, electronic, optical, and thermal measurements and theoretical simulations we are establish a predictive understanding on how the electronic and phonon structure of the parent materials can be altered in this reduced framework and tuned via a surface bound ligand. Bestowing these novel properties onto existing materials can be truly only possible on the molecular-scale, and is expected to lead to novel competitive optoelectronics, thermoelectrics, spintronics, and chemical/biochemical sensors materials. Are research is focused along the following thrusts;
1) Dimensionally-Reduced Metal Chalcogenides - Metal chalcogenides are some of the most well-studied classes of materials in the condensed matter research community due to the wealth of interesting physical phenomena and applications. We are rationally designing dimensionally reduced variants of these crystalline materials in order to create novel superconductors, photovoltaic materials, catalysts, and thermoelectric materials.
2) 2D Materials Beyond Graphene - Since the discovery of single-layer graphene’s unique electronic properties, there has been great interest in the synthesis, properties, and application of single layers of graphene and other inorganic two-dimensional layered sheets. We are synthesizing new single-atom thick layered materials that have potentially novel optical and electronic properties. These materials hold great potential as active materials for a host of applications including photovoltaics, spintronics, molecular electronics, and thermoelectrics.
3) Dynamic Self-assembling 0D/1D Materials for Medical Imaging We are learning how to exploit the superior properties of inorganic and peptide nanomaterials to improve upon the state-of-the-art medical diagnostic and therapeutics. For example, one of our long-term goals is to develop clinically translatable agents for detecting cancer using self-assembling peptide materials that contain different metals for imaging (MRI, PET, etc.). We are developing dynamic materials that respond to the chemistry of the tumor microvasculature to enhance the sensitivity of traditional diagnostic and therapeutic agents.
Josh has funding available and is looking for enthusiastic and motivated graduate students.
