Timothy Strobel's research is centered around the synthesis and characterization of novel materials for energy and advanced applications. New materials are synthesized using unique pressure-temperature conditions and through innovative processing pathways. Of particular interest are extended structures rich in carbon, silicon and germanium, as well as hydrogen-rich molecular systems. He received his B.S. (2004) and Ph.D. (2008) in Chemical Engineering from the Colorado School of Mines. In 2008 he joined the Geophysical Laboratory of the Carnegie Institution of Washington as a Carnegie Postdoctoral Fellow and was appointed Staff Scientist in 2011.

Materials
Washington, DC— A team including several Geophysical Laboratory scientists has developed a form of ultrastrong, lightweight carbon that is also elastic and electrically conductive. A material with such a unique combination of properties could serve a wide variety of applications from aerospace engineering to military armor. Carbon is an element of seemingly infinite possibilities. This is because the configuration of its electrons allows for numerous self-bonding combinations that give rise to a range of materials with varying properties. For example, transparent, superhard diamonds, and opaque graphite, which is used for both pencils and industrial lubricant, are comprised solely of carbon.
Materials
Washington, DC—It would be difficult to overestimate the importance of silicon when it comes to computing, solar energy, and other technological applications. (Not to mention the fact that it makes up an awful lot of the Earth’s crust.) Yet there is still so much to learn about how to harness the capabilities of element number 14.
Materials
Washington, DC—Germanium may not be a household name like silicon, its group-mate on the periodic table, but it has great potential for use in next-generation electronics and energy technology. Of particular interest are forms of germanium that can be synthesized in the lab under extreme pressure conditions. However, one of the most-promising forms of germanium for practical applications, called ST12, has only been created in tiny sample sizes—too small to definitively confirm its properties.
High Pressure
Washington, DC— Did you know that there are at least 17 crystalline forms of ice, many of them formed under extreme pressures, such as those found in the interiors of frozen planets? New work from a team led by Carnegie’s Timothy Strobel has identified the structure of a new type of ice crystal that resembles the mineral quartz and is stuffed with over five weight percent of energy-rich hydrogen molecules, which is a long-standing Department of Energy goal for hydrogen storage.  
Materials
Washington, DC, 18 March 2016—Geophysical Laboratory team Tim Strobel, Venkat Bhadram, and alum DuckYoung Kim, has discovered a new transition metal, titanium pernitride, TiN2, which is ultraincompressible (bulk modulus ~360-385GPa) and could be a potential superhard material.
Department
The Geophysical Laboratory's Tim Strobel talks in the November issue of New Scientist about hacking silicon's structure to make it more efficient for use in computer chips and solar panels.
Materials
Washington, DC—Silicon is the second most-abundant element in the earth's crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices—carbon is to biology as silicon is to technology.
High Pressure
A research team from the Geophysical Laboratory, including Oleksandr Kurakevych, Timothy Strobel, Duck Young Kim and George Cody, has reported the synthesis of an ionic semiconductor, Mg2C, under high-pressure, high-temperature conditions, which is fully recoverable to ambient conditions.
High Pressure
Washington, DC, 21 December 2012 — Researchers from the Geophysical Laboratory have observed a new compound form of sodium and silicon - a "covalent metal," with unusual structural and electrical properties.
High Pressure
Washington, DC, 28 March 2012- A Carnegie scientists' observations have led the way to stabilizing tungsten hydrides under high pressure.
