Eli LIlly Recruitment and Collaboration Visit

Brian Millen and Oksana Chkrebtii Discuss Research Over Cake

On September 29, 2016, Eli Lilly Statistician and Senior Research Advisor Brian Millen visited Ohio State University. He took time to get to know the students and faculty of the Statistics and Biostatistics graduate programs. Since Eli Lilly's headquarters is just a few hours down the road in Indianapolis, we look forward to developing collaborations and look forward to welcoming him back to Ohio State soon.

2016 Statistics and Biostatistics Graduate Student Poster Session

 Yihan Sui discusses her work with Lo-Bin Chang

Students and faculty alike enjoyed the 2016 annual Statistics and Biostatistics Graduate Student Poster Session, held in the Cunz Hall atrium on September 15. Two of the eight posters were presented by Biostatistics PhD students:

  • Ranran Dong on "Stepped Wedge Cluster Randomized Controlled Trials With Two Layers Of Clustering: Designs And Comparisons Of Power"
  • Yihan Sui on "Modeling Disease Incidence by Using Spatial Temporal Multivariate Poisson Model."

During the session, senior graduate students discussed their research work with graduate students and faculty across the Statistics and Biostatistics programs while enjoying some light refreshments. In addition to learning about the new biostatistical work, the event was a wonderful chance to catch up with friends and colleagues and meet new students at the start of the new academic year.

Congratulations Ranran and Yihan!

PhD Students present at the 2016 Joint Statistical Meetings

Brittney Bailey with Darius McDaniel, Michael Thomas, and Jemar Bather at JSM

In early August, many of the Biostatistics PhD students traveled to Chicago to attend sessions explaining cutting-edge biostatistical developments, explore employment opportunities and meet colleagues and friends at the Joint Statistical Meetings (JSM). Ohio State student Brittney Bailey was even featured on the JSM website front page!  The photo (linked above) shows her strengthening her network at the Student Mixer. Four Ohio State Biostatistics PhD students presented their work over the course of the five-day event:

  • Brittney Bailey, joint with A. Shoben: "Analyzing Binary Outcome Data from a Partially Clustered Design"
  • Mark Burch: "Law of Large Numbers for Generalized Network-Based SIR Models"
  • Ranran Dong, joint with A. Shoben: "Stepped Wedge Cluster Randomized Controlled Trials with Two Layers of Clustering: Designs and Comparisons of Power"

Congratulations to Brittney, who was awarded the Lester R. Curtin award, "established to help promising young health statisticians get the skills and training they need to make significant contributions in their area of study" (ASA website). Brittney traveled to the Conference on Statistical Practice in February to receive her award. She is the second Ohio State Biostatistics student to receive this award in the last three years. Again, congratulations Brittney!
