Stephen M. Durbin
Professor, Department of Physics

Professor Durbin's research interests have focused on unique applications of x-rays to fundamental questions of condensed matter physics, biological physics, and to the dynamical interaction of x-rays with matter.  Using some of the best x-ray beamlines in the world at the Advanced Photon Source (Argonne National Lab), recent investigations of heme proteins utilizing resonant nuclear absorption by the 57-Fe Mossbauer isotope have shown how the coupling between the protein backbone with the heme molecule can play a role in the biological functioning of these important macromolecules.  Other projects include the application of terahertz radiation to the detection of biological materials and for understanding the role of "biological water" in protein dynamics.  Future plans include the development of techniques for time-resolved x-ray detection with picosecond resolution, for probing the transition between electronic excitations and lattice displacements in ultrafast reactions.

Nicholas J. Giordano
Hubert James Distinguished Professor of Physics
Head, Department of Physics

The physics of nanostructures and mesoscopic systems
Dr. Giordano’s research group studies the properties of very small metallic systems, including such phenomena as the Kondo effect in one and two dimensions, the behavior of domain walls in very narrow ferromagnetic wires, and fluid flow in extremely small structures.  Students who have recently been involved in this work include Todd Jacobs, Baris Cetin, Jiangtao Cheng, and Jacob Millspaw.  More details along with some of our recent papers are given on our mesoscopic page.

Musical acoustics and the physics of the piano
Dr. Giordano’s group is studying why the piano sounds like a piano.  They are developing a physical model of the piano—this model will use Newton's laws to calculate the motion of all of the pieces of a piano along with the sound pressure which is produced.  This work also involves experimental studies of piano hammers, strings, and soundboards.  This work has been done by Andy Korty, James Winans, Stu Dietz, John Millis, James Roberts, and Laura Rueff.  More details of this work, including some of the group’s recent publications, are given at their piano www pages.

Computational neuroscience
Dr. Giordano’s group is starting several projects in the area of computational neuroscience.  This work has to do with the nervous system and how it does various sorts of "computations".  They are interested in the detailed physics, biophysics, and neuroscience of how signals are generated and propagate in the brain and in how the brain processes these signals.  These projects are described in more detail on the neuroscience page, where the groups’ publications in this area can be found.  This work has been done by Jasper Wang and Zhouhan Liang.

Computational physics
Dr. Giordano has a long standing interest in doing and teaching computational physics.  This work includes the musical acoustics described above, along with his book, Computational Physics.

Guitar acoustics
Dr. Giordano’s group has just begun some modeling studies of the guitar.  Some information on this work and some calculated guitar tones can be found here.

Eric Riggs
Associate Professor, Department of Earth and Atmospheric Sciences and Curriculum and Instruction
Co-Director of the Center for Research and Engagement in Science and Mathematics Education (CRESME) at Purdue University

Professor Riggs is a member of the Earth System Science Education research group at Purdue University. He is also the President of the National Association of Geoscience Teachers, the premier professional society for geoscience education research and teaching and publisher of the Journal of Geoscience Education.  Riggs and his graduate students study many related aspects of field-based teaching and learning in the geosciences, focusing on issues of geoscience knowledge construction, spatial cognition related to geoscience expertise, and cross-cultural education. Riggs is the co-founder of the Indigenous Earth Sciences Project, based at Purdue since 2006, which is a research and outreach effort working to make geoscience education accessible and useful to Native Americans across North America.  Riggs’ scientific research is in the area of rock deformation, structural geology, and mineral physics.

Chris Sahley
Professor, Department of Biological Sciences
Associate Dean for Undergraduate Education

Professor Sahley’s research interests have been centered on the elucidation of the cellular, molecular, and neural network mechanisms underlying learning and memory.  A secondary research area has been the neural mechanisms mediating recovery of function following neural trauma.  More recently, she has joined with Science Education faculty on proposals aimed at developing effective and innovative approaches to STEM education. Professor Sahley’s administrative duties include developing collaborative initiatives and creating new programs across colleges.  Professor Sahley works closely with Barb Clark, the Director of the Science Diversity Office, on all issues of diversity but with a special focus of the success of women students and faculty.

Bill Walker
Director, K-12 Outreach
Executive director, I-STEM Resource Network

Bill Walker is the Executive Director for the I-STEM (Indiana Science, Technology, Engineering, and Mathematics) Resource Network.  As Executive Director for the I-STEM Resource Network, Bill organizes and manages the creation of a statewide resource network for K-12 STEM education.  I-STEM activities have included addressing professional developments needs for teachers of mathematics and science; facilitating the development of a webpage that will be a leading information source to students, parents, teachers, administrators, and higher education personnel in K-12 STEM education, and initiating a statewide network with regional lead institutions of higher education to facilitate regional and statewide improvement in K-12 STEM education.  Bill is also the Director of Science K-12 Outreach at Purdue University, which creates professional development programs for teachers of science and mathematics.  Prior to working with I-STEM, Bill taught high school and middle school mathematics for eight years.

Gabriela Weaver
Associate Professor, Department of Chemistry
PI for Center for Authentic Science Practice in Education (CASPiE)

Gabriela Weaver’s research focuses on developing, implementing and assessing innovative instructional methods and materials for chemistry. The overall goals of her work are to use these to achieve greater retention of students in the sciences, to help them develop a better understanding of the material, and to motivate their interest in the subject. Specific activities in Weaver’s research include developing research-based or inquiry-based learning, developing instructional materials for active learning, developing or adapting instructional technologies to facilitate student learning, and implementing and assessing the educational impacts of these materials. She has worked with teachers in K-12 as well as with students and faculty at the college undergraduate level (including 2-year colleges).  With CASPiE, she has been engaged not only in the development of instructional materials, but also in research to examine the effects of this instruction on students’ scientific process skills, such as experimental design, and scientific communication skills. Research on faculty development is another component of the CASPiE research, using theories from communities of practice to understand the engagement of instructors as practitioners of science research within their classroom teaching.
