  • Dr. Hepel research studies focus on novel nanoscience phenomena in electron transport in atomically-thin nanowires, catalysis on nanaparticles and nanoporous materials, chemical quantum interference, interactions of submonolayer films with biomolecules, and applications of new discoveries in emerging nanotechnologies


  • Her interest in incorporating interdisciplinary and nanoscience projects in undergraduate courses brings an exciting opportunity for students to learn skills and understanding of nanoscience for future careers in chemistry, biosensors, piezoimmunosensors for the detection of biomolecules, toxicants, and heavy metals, as well as in materials science, molecular electronics, and energy technologies, such as the fuel cells, solar photovoltaics, hydrogen energy, lithium batteries, electrochromic devices, etc.


  • The cutting-edge research introduces students to the state-of-the-art modern instrumentation, including Atomic Force Microscope, Scanning Tunneling Microscope, Quartz Crystal Nanogravimetric and Immittance Spectroscopic instruments, Ultra-Fast Electrochemical Potentiostats, Quantum Nanobridge Impedance Spectroscopy, and others.
