Dr. Stacy Gates-Rector
International Centre for Diffraction Data
Newtown Square, PA
Dr. Gates-Rector is a Senior Scientific Editor & the Project Leader over New Projects at the International Centre for Diffraction Data (ICDD). She manages and maintains data collection for the “Organics” project that is published in the PDF-4/Organics product. Additionally, she reviews and standardizes experimental data and crystallographic information for publication in all of the PDF products. Prior to joining ICDD team, she investigated transparent conducting oxides for use in photovoltaic devices. Her scientific education and training is in chemistry (with focus on inorganic chemistry and crystallography).

As a member of ICDD staff, she carries out daily tasks that are focused on improving the quality and the data content of the Powder Diffraction File (PDF). Additionally, Stacy has been working on a project geared toward incorporating non-standard targeted materials into the database. Upon taking on this task, she worked with the polymer subcommittee group to redefine the “POL” sub-file, and make it a more efficient analysis tool. As of PDF-4/Organics Release 2016, approximately 1570 polymer entries have been included in the PDF under the “POL” sub-file classification.   

Aside from her professional role in science, Dr. Rector enjoys teaching and being active in her community. She actively participates in ICDD education programs and has been active in science-based, community outreach since 2004. She was a essential part of establishing an NSF funded outreach program: S.C.O.P.E. (Scientists Changing Our Pre-college Education) where scanning electron microscopy (SEM & SEM-EDS) is used remotely at secondary and high schools to teach students about advanced analytical instrumentation.

Dr. Soorya N. Kabekkodu (Suri)
International Centre for Diffraction Data
Newtown Square, PA

Suri received his MS in Chemistry from the Mangalore University in India in 1992. Suri’s thesis, “Structural Phase Transition in Inorganic Systems: Insights from X-ray Diffraction Studies”, earned him his PhD in chemical crystallography from the Indian Institute of Science, a premier research institute in India, in 1999.

Suri joined the ICDD in June of 1999 as a Post Doctoral Research Fellow and accepted the position of Editor of Calculated Patterns in 2000. In 2003, he chaired the task group to develop a method to assign quality marks to calculated patterns. He developed and implemented the algorithm to evaluate the quality of calculated patterns based on the task group outcome.  Suri has calculated and critically-reviewed (using his data evaluation suite) more than 900,000 diffraction patterns.

Suri is currently the Editor-in-Chief of the Powder Diffraction File (PDF) where he remains heavily involved in the significant crystallographic review of crystal structures and X-ray diffraction patterns prior to their publication. Over the years, he has developed various algorithms to evaluate and classify crystal structures, optimizing the editorial process. Automating the subfile assignment has enhanced the search/match capability using the Powder Diffraction File. Suri has spearheaded several projects leading to many of the enhancements to the PDF, including the addition of atomic coordinates, quality mark assignment, extensive cross-referencing, structure prototyping and classification. The quality improvements to the PDF have a direct impact on phase identification processes.

Newtown Square, PA

Charles received his B.S. from Manhattan College, NY and his M.S. from Villanova University, PA. He currently works as a Senior Software Engineer in the Science Department at the ICDD. Charles is registered as a Professional Engineer in the state of Pennsylvania. Back in the days when the database was an ASCII text file, he coded numerical methods that laid the groundwork for our current Search Match product, Sieve++. Charles has seen the evolution of ICDD’s software from the time when it was a single product, fitting onto a single CD, through its transition to a 5 GB relational database, supporting five different products, in five foreign languages. He now prepares the installations for these products, a task which requires close teamwork within the many facets of the Science Department, as well as careful testing and documentation. This insight into the details of production and assembly allows him to sympathetically assist analysts experiencing technical difficulties.
