Dr. Christian Kisielowski was Principle Investigator and Staff Scientist at the Molecular Foundry, Lawrence Berkeley National Laboratory, CA. He was awarded his PhD in natural sciences (physics, mathematics, chemistry) and his Habilitation in experimental physics at the University of Cologne / Germany in 1985 and 1990, respectively, for performing spectroscopic studies of defects in semiconductors. Thereafter, he joint AT&T Bell Laboratories (1991 – 1994) where he invented new quantitative tools for image analyses in High Resolution Electron Microscopy. Since 1997, Dr. Kisielowski serves as Staff Scientist at the NCEM where he developed and applied atomic resolution electron microscopy, sample preparation, and computational tools. He was the first to demonstrate sub-Ångstrom resolution in 1999 by mid-voltage phase contrast microscopy and reached record resolution below 0.5 Å, which touches the physical limits of obtainable resolution and was established in 2009 within the TEAM Project (Transmission Electron Aberration-corrected Microscopy).

Recognizing that beam-sample interactions and time resolution are most challenging aspects of atomic resolution electron microscopy, he developed a low dose rate technique, which enables time-resolved investigations of functionality on a single atom level in three dimensions and environmental meaningful conditions (elevated p, T). Instrumentation providing spatiotemporal resolution of 1 Å and 1 ps is within reach. Such capabilities touch quantum mechanical limits and are of significant interest in the context heterogeneous systems for sustainable energy research that commonly contain soft and hard matter components including single-digit nanoparticles, two-dimensional materials, interfaces, surfaces or point and extended defects. Dr. Kisielowski has published over 200 peer reviewed articles including multiple publications in respected journals such as Science, Nature Materials, Nano Letters, Angewandte Chemie, Phys. Rev. Lett., and others. His h-index is 60 and he retired from the LBNL in 2022 to consult at different institutions.
