Work Experience:
Yaqiao (Y. Q.) Wu is currently a Research Associate Professor in the Materials Science & Engineering Department (MSE) at Boise State University (BSU), and he is the instrument lead for the TEM (Tecnai TF30-FEG STwin) and atom probe (LEAP 4000X HR) in the Materials and Characterization Suite (MaCS) at Center for Advanced Energy Studies (CAES) in Idaho Falls, ID.

Dr. Wu received his Ph. D. in Materials Science and Engineering from the Institute of Metal Research, Chinese Academy of Sciences, China, in 2000. By utilizing the high-resolution transmission electron microscopy (HRTEM) technique, his Ph. D. research on the structural evolution of single-crystal silicon upon indentation revealed micro-plastic fracture behavior along the propagation direction of the Si crack tip and revealed the amorphization of silicon under the indentation on an atomic scale. He was a joint-training Ph.D. student member of the atom probe group at the National Institute for Materials Sciences (NIMS) at Tsukuba, Japan from 1998 to 1999, where he studied the microalloying effect in _-Fe/Nd2Fe14B-based exchange-spring nanocomposite magnets by using a combinational TEM and atom probe tomography (APT) techniques. He received the Special Award of the President Scholarship from the Chinese Academy of Sciences in 1999 for this research. From 2000 to 2002, Dr. Wu continued his studies on exchange-spring nanocomposite magnets at NIMS as a Science and Technology Agency (STA) Fellow. Between 2002 – 2011 he held several positions at Ames Laboratory, where he was mainly engaged in designing nanocrystalline magnetic alloys and performing chemical and structural analysis at the atomic level. By again utilizing TEM and APT techniques, his research revealed the behaviors and effects of various microalloying elements in rare-earth (RE) and non-RE based magnetic alloy systems for future alloy design and applications. As a postdoctoral research associate, his research on the local order in the icosahedral Cd84Yb16 quasicrystalline phase was awarded the “Outstanding Poster Award” at the 2003 MRS Fall meeting in Boston. In 2006, Dr. Wu became a permanent staff member (Assistant Scientist) in Ames Laboratory. He joined Boise State in his current position in August 2011.

Dr. Wu’s research interests are in materials design, synthesis, property analysis, nanoscale structural and chemical characterization. He specializes in establishing connections between structure, chemistry and behavior via transmission electron microscopy and atom probe tomography techniques. He has over 60 publications in journals such as Acta Materialia, Scripta Materialia, Applied Physics Letters, Physics Review B, Journal of Applied Physics, Journal of Materials Research, Philosophical Magazine Letters, etc., and over 40 conference presentations.
