Research Experience

2017 March-present RStudio
internship under Jenny Bryan developing googledrive package

2016-2017 Vanderbilt University
NIH Big Data to Knowledge Training Fellow
Training included attending three courses in the computer science department (Algorithms, Topics in Big Data, & Program Design and Data Structures for Scientific Computing), as well as collaborating on methods development for large scale statistical inference and sensitivity to unmeasured confounding analyses.

2015-2016 Vanderbilt University
Research Assistant, Department of Biostatistics and VA Tennessee Valley
Perform statistical analyses and large-scale inference on a retrospective national cohort of 411,055 Veterans Health Administration patients. Experience with manipulating and analyzing large datasets, as well as integrating data from multiple sources, such as the National Death Index, Medicare, and Medicaid. Current focus is the association between diabetes medications and congestive heart failure.

2015 Summer Cleveland Clinic
Summer Graduate Fellow, Department of Quantitative Health Sciences
Worked under Nancy Obuchowski on multi-reader multi-case ROC analyses. Conducted a examining the effect of location bias in two large MRMC ROC studies, comparing three ROC scoring methods. Compared one method that only uses the maximum confidence score and does not take location bias into account (maxROC), and two methods that take location bias into account: the region of interest ROC (ROI-ROC) and the free-response ROC (FROC).

2013 Summer Graham Colditz Laboratory
Summer Intern
Created custom labor curves based on women in laborā€™s individual characteristics. Obtained model estimates and 95% confidence intervals for the custom labor curves using bootstrap resampling methods.

2012-2014 Gutmann Research Laboratory
Research Assistant, Washington University School of Medicine, Department of Neurology
Performed microarray analysis using programs such as R and Partek to determine unique transcripts. Worked with researchers to prioritize transcripts for validation.

2012-2014 Washington University School of Medicine
Statistical Data Analyst, Department of Surgery, Division of Public Health Sciences
Began as a research assistant and promoted to statistical data analyst position. Experience in planning and executing analytical projects. Lead survey data manager for Center for Outpatient Health Study focusing on health literacy. Performed statistical analyses including univariate, bivariate, multivariate, and mixed methods. Extensive SAS experience in analyzing large datasets including data step processing, data manipulation, macro creation, data mining, regression analyses, survival analyses, and two-time winner of SAS Student Ambassador award.
