Our laboratory investigates the transport of heat, electrical charge, and spin through solids, and the conversion of energy from heat to work. We focus on exploring experimentally new physical mechanisms that can lead to improvements in heat transport (thermal conductivity) and heat-to-work conversion (heat engines), with emphasis on solid-state systems with no moving parts. We work on thermoelectric materials, magnetic materials, and quantum materials.

Experimental investigation of electron, phonon and spin transport properties, semiconductor, semimetals, topological and magnetic materials and nanostructures. Contributions:
- The thermal chiral anomaly is a new way for electrons to carry heat. This process applies only to electrons in Weyl semimetals, in which electrons are massless but have a "chirality". In the presence of a temperature gradient, energy (heat) is created by electrons of one chirality, annihilated by electrons of opposite chirality, and this creates a heat transfer mechanism, grounded in quantum mechanics, that dominates all other mechanisms (2021). It offers the possibility of realizing all-solid-state heat switches.
- Goniopolar materials exhibit simultaneous n- and p-type behavior by the same charge carriers (2019). They enable the construction of transverse thermoelectric generators that don't need electrical contacts at their hot side, and mostly eliminate efficiency losses in contact resistances (2021).
- Phonons in diamagnets respond to magnetic fields (2015)
- The giant spin-Seebeck effect in InSb is as large as the largest thermopower values measured (2012).
- Resonant levels increase the thermoelectric figure of merit (2008).
- Large thermopowers in quantum wires due to size-quantization (2002-4)
Geometrical magnetoseebeck and magnetoresistance effects – the latter resulted in commercial position sensors used on crank and camshafts by GM (1990s).
