Miguel José Yacamán (born 1946 in Córdoba, Veracruz) is a Mexican physicist who has made contributions to the fields of materials science, nanotechnology, and physics. His research has focused on the correlation of structure and properties in nanomaterials and he has developed electron microscopy methods to study nanoparticles and 2-D materials. The present focuses of his work are to develop the nanoscale equivalent of high entropy alloys and new catalysts to produce cleaner fuels. He earned his Ph.D. in Physics in 1972 from the National Autonomous University of Mexico and did his postdoctoral materials science studies at the University of Oxford. He was also a Postdoctoral Fellow at the NASA Ames Research Center in Mountain View, California from 1978-1979. Yacamán became the director of the Institute of Physics from 1983-1991. He was the Reese Endowed Professor in Engineering at the University of Texas at Austin from 2001-2008. In 2008, he joined The University of Texas at San Antonio (UTSA) to chair the Department of Physics and Astronomy in the College of Sciences until 2018. As of 2019, he is a professor of physics at Northern Arizona University. Research Yacamán has done research on the structure and properties of nanoparticles including metals, semiconductors, and magnetic materials. He has worked on synthesis and characterization of new materials (mainly nanoparticles), surfaces and interfaces, defects in solids, electron diffraction and imaging theory, quasicrystals, archaeological materials, catalysis, and physics and chemistry of asphaltenes. Yacamán is the author of 9 books and over 550 technical papers with over 32,000 total citations. His work in nanoparticles opened a new era in electron microscopy of finite size. He has acted as associate editor of journals such as Acta and Scripta Metallurgica, Catalysis Letters, Journal of Nanostructured Materials, Microscopy Research, and Techniques and Materials Chemistry. In June 2005, in collaboration with Jose Luis Elechiguerra (Fulbright Fellow), he published a groundbreaking paper on the inhibitory properties of silver nanoparticles against HIV-1. (Journal of Nanobiotechnology) Honors and distinctions Yacamán has held the Guggenheim Fellowship, and was awarded numerous prizes such as the National Prize of Sciences of Mexico and the Prize of the National Academy of Mexico in Exact Sciences. He is a member of the Mexican National Research System (level III), and in May 2003 he was appointed National Researcher of Excellence by CONACyT. Yacamán has also made many contributions to Mexican science as Science Director of CONACyT (National Council
