October 27 - {redcapAPI} R package (Teams presentation)

On Friday, October 27, at 1:30 p.m. Central Time, application developer Savannah Obregon will speak about the {redcapAPI} R package in a free presentation on Microsoft Teams. She is a member of the Vanderbilt Biostatistics team that developed a data processing layer within the package to help support clinical trials. REDCap is a secure web platform simplifying database and survey creation, while R facilitates reproducible research through its scripting capabilities, R Markdown integration for reports and package management. Originally designed for exporting the raw API data from REDCap, redcapAPI now includes robust data handling, ensuring reliable retrieval of analysis-ready data. It optimizes the transformation of raw REDCap data with cryptographic storage of API keys and streamlined API calls, making it a powerful tool.

Obregon graduated from Lipscomb University with a bachelor's degree in information technology management, with a minor in business and concentration on web development. She was a speaker at R/Medicine 2023, and she presented a poster on {redcapAPI} during the department's 20th anniversary celebration. She has made crucial contributions to the data coordination of ACTIV-6 since joining our department.

For access to this presentation, contact Ryan Moore, organizer of the department's Statistical Computing Series.

Celebrating our current postdocs

In observance of National Postdoc Appreciation Week, we thank our two current postdoctoral research fellows for their contributions to our department.headshots Jia Li and Leila Azinfar

Jia Li (left) previously studied at Xiamen University and Shanghai Technology University as well as the German Heart Centre in Munich before joining our department four years ago. Her projects have included working on a single-cell multi-resolution marker-based annotation method (scMRMA), a single-cell and spatial transcriptomic clustering method (aKNNO), and single-cell analysis of Crohn's disease. Her accomplishments include a first-authored paper on scMRMA in Nucleic Acids Research.

Leila Azinfar (right) joined our department in April with a PhD in bioengineering from Missouri and master's degrees from Shaheed Behest University of Medical Sciences (biomedical engineering) and Amirkabir University of Technology (radiological systems engineering). At Vanderbilt, she works with Amir Asiaee, primarily on the causal effect estimation of regulatory molecules. Her publications include a first-authored paper on high-resolution imaging in the Journal of Biophotonics 

 

 

 

Vanderbilt Biostatistics to host ASA traveling short course

On October 20, we will host the short course “From R Markdown to Quarto” with the Middle Tennessee chapter of the American Statistical Association (ASA). This one-day course is designed for those who want to take their R Markdown skills and expertise and apply them in Quarto, the next generation of R Markdown. Quarto is an open-source scientific and technical publishing system that offers multilingual programming language support to create dynamic and static documents, books, presentations, blogs, and other online resources. The course will be taught by Mine Çetinkaya-Rundel, professor of the practice of statistical science at Duke University. It will be held in Light Hall from 9:30 a.m. to 5:00 p.m. See the course webpage for details and registration.

Members of the Middle Tennessee chapter of the ASA receive discounted registration. The cost is $70 for student members; $90 for student non-members; $140 for non-student members; and $180 for non-student non-members. Visit the ASA Chapters page to join or renew your membership.

Assistant professor and director of graduate recruitment Simon Vandekar is the president of the ASA's Middle Tennessee chapter. Other chapter officers from our department include assistant professor Amber Hackstadt, associate professor Robert Johnson, and associate professor Rameela Raman.
