Ken Livi – President

Materials Characterization and Processing Facility, Johns Hopkins University

Kenneth Livi is an associate research scientist in the Department of Materials Science and Engineering and director of operations for the Materials Characterization and Processing Facility. His research focuses on the characterization of inorganic and organic materials, biomaterials, earth materials, and surfaces of nanomaterials through electron microscopy.

He received a BS and MS from State University of New York at Stony Brook in 1980 and 1983, and a PhD at the Johns Hopkins University in 1995.

Tagide deCarvalho – President Elect

Keith R. Porter Imaging Facility, University of Maryland, Baltimore County

Tagide deCarvalho is the director of the Keith. R. Porter Imaging Facility (KPIF) at UMBC where she oversees and performs optical and electron microscopy for on-campus faculty as well as external academic and industrial clients. She received a PhD in Behavior, Ecology, Evolution and Systematics from University of Maryland, College Park in 2009. Her postdoctoral work at the Carnegie Institution for Science, Department of Embryology involved extensive confocal microscopy, which set the stage for her career as a microscopist. She works with a wide variety of life and material science samples and has a special interest in imaging viral particles.

Emma Bullock – Treasurer

Earth and Planets Laboratory, Carnegie Institution for Science

Emma Bullock is a Microbeam Specialist at the Earth and Planets Laboratory at the Carnegie Institution for Science. She operates Carnegie’s JEOL 8530 field emission electron microprobe, equipped with the xCLent cathodoluminescence detector, five WDS spectrometers, two EDS detectors, a cold trap for high precision carbon analysis and Probe for EPMA software. She also runs the Zeiss Auriga Scanning Electron Microscope (SEM) at Carnegie. She has authored and coauthored many papers in the fields of geology, planetary science and material science, and has expertise in imaging and quantitative analysis. Prior to joining Carnegie, she was a geochemist at the Smithsonian Institution.

Thomas Lam – Secretary

Smithsonian Museum Conservation Institute

Thomas Lam has a Ph.D. in Ceramics from Alfred University, NY. After earning his Ph.D., he completed postdoc at the National Institute of Standards and Technology. He is a physical scientist at the Museum Conservation Institute (MCI), where he applies his knowledge of material science and characterization skills (including scanning electron microscopy electron dispersive spectroscopy (SEM-EDS), cathodoluminescence (CL), X-ray fluorescence (XRF), and microfade testing) as part of the MCI technical studies team. The electron microscope Thomas performs research and technical studies with atMCI is a Hitachi S3700-N variable pressure SEM equipped with Bruker XFlash 6│60 EDS detector, Bruker XTrace (35 micron micro-XRF with a mapping substage), and Gatan ChromCL2 for CL.

Andrea Blake Brothers – Outreach Officer

American University/Hall of Science

Light (PLM), electron (TEM & SEM), and dual beam (FIB/SEM) microscopy instrumentation to include sample preparation, imaging, and spectral analysis techniques for biological, pharmaceutical, and materials science (including semiconductor) applications.

Andrea Blake Brothers joined American University in January 2019 as Instrument Coordinator in the Chemistry Department. She has worked in both academia and industry for 40 years, utilizing various microscopy and microanalysis techniques in experimental design to help solve problems. Research experience includes positions with The University of South Carolina, School of Medicine; Georgetown and George Washington Universities; Biovail Pharmaceuticals; the Howard Hughes Medical Institute, Janelia Farm Research Campus, Micron Technology, and Tescan.

Ru-Ching Hsia – Council

Department of Embryology, Carnegie Institution for Science

I was a Professor in the Department of Neural and Pain Sciences at the University of Maryland Baltimore until 2021. I am now working in the Department of Embryology, Carnegie Institution for Science.  I perform biomedical-related research using transmission and scanning electron microscopy techniques.  I also teach courses and host workshops to promote microscopy and imaging-related sciences.   I believe communication and sharing our knowledge is an integral part of research.  When I am not working in the EM lab, you will find me in rubber boots working in my garden, tending to my goats and chickens.
