Our wonderful instructors for the 2017 ACA Summer Course!

Christine Beavers–  Advanced Light Source, Berkeley Lab & COMPRES, UC Santa Cruz

Christine Beavers

Christine received both her B.S. in Chemistry and her Ph.D in Analytical Chemistry at the University of California, Davis, with the latter supervised by Professor Marilyn Olmstead.  During her Ph.D, Christine was informed that her weakly diffracting samples would benefit from high-intensity synchrotron X-rays, and since first seeing this light, she has had no desire to tear herself away from the synchrotron.  Her experiences on Beamlines 11.3.1 and, more recently, 12.2.2 at the Advanced Light Source have given her familiarity with the potential evils lurking in single crystal and powder diffraction (twinning, disorder, poor diffraction) as well as methods for damaging perfectly good crystals for fun and insight (high pressure, high/low temperature, photocrystallography, environmental gas cells, among others). She has acquired a great deal of knowledge concerning synchrotron radiation, X-ray beamline design and operation, as well as crystallographic data analysis and refinement.  When she is not coaxing high energy X-rays out of Beamline 12.2.2 for extreme conditions experiments, Christine enjoys riding her horses and running.

Lee Daniels – Rigaku Oxford Diffraction

Lee Daniels is a sales manager for Rigaku Oxford Diffraction. Prior to his tenure at Rigaku, Lee was the director of crystallography at Texas A&M University’s Laboratory for Molecular Structure and Bonding, following his position as staff crystallographer at Iowa State University. Lee has a BS in chemistry from Abilene Christian University and a PhD in inorganic chemistry from Texas A&M, under the direction of the late Prof. F. Albert Cotton. He is active in the American Crystallographic Association and the American Chemical Society, and served for several years as a co-editor for Acta Crystallographica. Lee enjoys cycling, racquetball and antique autos when he is not tackling a tough crystallographic problem.

Alexander Filatov – University of Chicago

Alexander Filatov

Dr. Filatov studied organic and medicinal chemistry at Lomonosov Moscow State University (Russia) working on the synthesis of a new family of substituted azoles. After receiving his MS degree (2002), he moved to upstate New York to study bowl-shaped polyaromatic hydrocarbons, their crystal packing and metal binding reactions. He received his PhD in Inorganic/Organometallic chemistry from the University at Albany, State University of New York in 2009. He was also concurrently employed as a staff crystallographer at the department of chemistry since 2008. In 2014, he was invited to lead the X-ray Research Facilities at the University of Chicago where he currently manages single crystal and powder X-ray diffraction instruments as well as an X-ray/UV photoelectron spectrometer that can be used for surface sensitive studies.

Alexander is also involved in a variety of collaborative projects with national laboratories. He helps researchers to utilize less commonly available advanced techniques such as resonant X-ray diffraction, X-ray absorption experiments (EXAFS/XANES) and small angle X-ray scattering experiments (SAXS) at the Argonne Nat’l Lab (Advanced Photon Source) and single crystal and powder neutron diffraction at the Oak Ridge Nat’l Lab (Spallation Neutron Source). He has contributed to many peer-reviewed publications, among them in highly ranked journals such as SCIENCE, Nature Chemistry highlights, JACS Spotlights, Angewandte Chemistry VIPs and others.

Alexander enjoys ACA meetings, talks and poster sessions, also volunteering his time in different committees and as a poster judge. In 2017, he serves as a chair of Service Crystallography group (Service SIG).

Danielle Gray – University of Illinois Urbana-Champaign

Dr. Danielle Gray studied at Augustana College where she received her B.A. in Chemistry, and later went on to Northwestern University where she received her Ph.D. in Inorganic Chemistry (2008) with James A. Ibers.  After graduate school she spent two years as a postdoctoral fellow at Northwestern University with Mercouri G. Kanatzidis where she studied intermetallic materials that had complex twinned and incommensurately modulated crystal structures.   Presently, Dr. Gray is the Director of the 3M Materials Chemistry Lab and G.L. Clark X-ray Facility at the University of Illinois Urbana-Champaign where she has managed the lab for the last six years.  Although this will be her first opportunity to instruct at the ACA Summer Course in Crystallography, she is actively involved in the ACA.  In 2014 she was a member of the International Year of Crystallography Committee for the ACA and is currently nominated for election to the Continuing Education Committee.

Robert (Bob) Von Dreele – Argonne National Laboratory

Robert Von Dreele

Robert (Bob) Von Dreele is a Senior Physicist at Argonne National Laboratory and works at the Advanced Photon Source.  He is the main developer (with Allen Larson) of the General Structure Analysis System (GSAS) and (with Brian Toby) of the open source python GSAS-II package. His scientific interests over the years has been Rietveld refinement and all of its possible applications including the initial analysis of neutron time-of-flight powder data, crystal structures at high pressure, texture analysis, crystallite size and microstrain analysis, protein structure refinement from powder data, and more recently incommensurate structures and stacking fault simulations all of which have treatments within the GSAS-II package.

He has a BS degree in Chemical Engineering from Cornell University (1966) and a PhD in Chemistry also from Cornell (1971) with a specialization in inorganic chemistry and an interest in crystallography. He immediately joined the faculty in the Chemistry Department at Arizona State University teaching mostly introductory chemistry to freshmen and pursuing research in crystallography. In 1972-3, while on leave, he was a National Science Foundation postdoctoral fellow at the Inorganic Chemistry Laboratory at Oxford University where he began his pursuit of powder diffraction crystallography, an endeavor he continues to this day. He attained the rank of Full Professor in 1981.

In 1986 he decided to pursue his main interests in neutron scattering and joined Los Alamos National Laboratory, New Mexico, as a Scientific Staff member at the LANSCE spallation neutron source where he was the Instrument Scientist responsible for two of the neutron powder diffractometers. During this time he was a Fulbright Fellow at the ISIS neutron scattering facility, Rutherford-Appleton Laboratory in Chilton, England (1986), received a Los Alamos National Laboratory Distinguished Performance Award (1998) for his work in protein powder diffraction, presented the 5th Joseph Morgan Lecture at Texas Christian University in 2000, and was made a Fellow of the Mineralogical Society of America in 2001.

In 2003 he joined Argonne National Laboratory as a Senior Physicist with a joint appointment between the Intense Pulsed Neutron Source and the Advanced Photon Source Argonne. In early 2008 the former facility was closed down and he is now full time at the APS. In 2007 he was elected Vice-President of the American Crystallographic Association and served as President in 2009. He received the Barrett Award in 2009 and the Hanawalt Award in 2013 for his work in protein powder diffraction.
