Lauren Poole (UCSB) was recognized for her presentation, titled “Quasi-static and dynamic mechanical behavior of co-continuous composites,” and Wyatt Witzen (UCSB) for his presentation “GND Mapping and Analysis in Shock Loaded Ta using 3D EBSD.” Congratulations!
The December 2021 issue of “Stewardship Science Today,” published by the NNSA’s Office of Research, Development, Test, and Evaluation (RDT&E), highlighted research by CREDDS member, George Pharr. The work, published in PNAS, reports a surprisingly low dislocation density underneath nanoindents in metals—a finding that challenges prevailing theories of nanoscale plasticity.
Two undergraduate summer researchers supported by CREDDS won outstanding presentation awards from the 2021 online REU (O-REU) program at Texas A&M University. Robert Kaman (Iowa State U., pictured below left) worked under the guidance of Brady Butler on a project titled “Quantification of Thermo-Hydrogen Refined Microstructural (THRM) features in Additively Manufactured Ti-6Al-4V.” Lauren Ward (Michigan State U., picture below right) worked with Michael Demkowicz on a project titled “Modeling the evolution of interpolating microstructures in nano-layered metal composites.”
On July 6, 2021, CREDDS and the Texas A&M University (TAMU) National Laboratories Office (NLO) co-sponsored a mixer for participants in NNSA-sponsored projects at TAMU. All CREDDS-sponsored undergraduate summer researchers at TAMU were also invited to participate. In addition to face-to-face networking, the meeting featured brief presentations by CREDDS director Michael Demkowicz, CENTAUR director Sherry Yennello, and Center for Nuclear Security Science and Policy Initiatives director Sunil Chirayath (pictured below).
CREDDS supported summer internships for 26 undergraduate students in 2021. Two of them carried out on-site internships at TAMU through the Undergraduate Summer Research Grant (USRG) program: Ryan Gordon (U. of Connecticut) and Vivian Spencer (Cornell U.). Twenty two took part in the online REU (O-REU) program at TAMU: Kassandra Avila (Texas Christian U.), Nina Castaneda (U. of Texas at Austin), Brittany DeNicholas (California Polytechnic State U.), Raphael Francisco (Georgia Tech.), Jaime Guerra (U. of Texas Rio Grande Valley), Reid Harrison (TAMU), Andres Hassun (U. of Texas at Austin), Robert Kaman (Iowa State U.), Karen Kline (U. of New Mexico), Ruben Lopez (U. of Houston, Clear Lake), Olivia McNally (U. of Arizona), Nathan Miller (Brigham Young U.), Justin Oca (U. of Texas at Austin), Isabel Parra (St. Mary’s U.), Aniket Patel (TAMU), Osvaldo Quintero (TAMU), Angel Randall (Texas A&M Prairie View), Ramon Sanchez (U. of Texas, Rio Grande Valley), Wendy Storms (TAMU), Andres Valdiviezo (U. of Texas at Austin), Lauren Ward (Michigan State U.), and Kalanie Wilson (Georgia Tech.). Two U. of Michigan students carried out on-site internships at U. of Michigan: Michael Stryk and Jeffrey Tschirhart.
During the 2020/2021 academic year, three CREDDS PhD students had extended internships at NNSA laboratories: Emmeline Sheu (TAMU) became the first out-of-state user to resume in-person work at the CINT facility at LANL (under the guidance of Kevin Baldwin), Ethan Sprague (U. of Michigan) carried out a remote internship under the guidance of LLNL staff members Gabe Guess and Ibo Matthews, and Marco Echeverria (U. of Connecticut) also had a remote internship at LLNL under the supervision of Alison Saunders.
CREDDS held its 2021 review meeting online on June 1-2, 2021. We are grateful to our external reviewers: Tod Caldwell (NNSA), Allen Dalton (NNSA), Michael Kreisler (NNSA), Darby Luscher (LANL), Sylvie Aubry (LLNL), Cristopher Seagle (SNL), and David Dombrowski (LANL).
CREDDS held its 2021 center scientific advisory committee (CSAC) meeting online on April 28, 2021. We are grateful to our CSAC members: Ellen Cerreta (Los Alamos National Lab), Mukul Kumar (Lawrence Livermore National Lab), Brad Boyce (Sandia National Lab), Don Brenner (North Carolina State U.), Lori Brady (Johns Hopkins U.), Pradeep Guduru (Brown U.), and Marisol Koslowski (Purdue U.).
Taylor Rosen, an undergraduate summer researcher supported by CREDDS, won an outstanding presentation award from the 2020 online REU (O-REU) program at Texas A&M University. Taylor worked under the mentorship of Prof. Justin Wilkerson on a project entitled “Effect of temperature dependent coefficient of thermal expansion on thermal stress weathering in small asteroids.” His presentation may be viewed here. Congratulations!
CREDDS supported 11 undergraduate students from around the US to take part in the online REU (O-REU, http://oreu.engr.tamu.edu) program held at Texas A&M University during the summer of 2020. The students are (starting at the top left in the image below): Christopher Wheatley (U. of Kentucky), Mack Cleveland (Texas A&M University), Natalie Goddard (Rice University), Emma Dickinson (U. of Pittsburgh), Ian Campbell (Georgia Tech), Zachary Adams (Georgia Tech), Joseph Caulkins (Carnegie Mellon University), Adira Balzac (MIT), and Bradley Robinson (Texas A&M University).
