Thank you for stopping by. Here you may find a little bit about me like publications, presentations, etc. I am a Senior Data Scientist at Biogen and a mathematician by training. I am a former intern at RStudio, where I worked with Max Kuhn developing the applicable modeling R package ッ. I enjoy the pure flavor of researching mixed with the applied nature of developing applications.



Selected Work Experience

Senior Data Scientist ⋯ 2019 Research and Development, Biogen Inc., Cambridge, MA (Current)
Lead analytical programming activities pertaining to biomarker data, clinical data, genomic data and other types of data analysis outside the typical analysis required for a clinical study report. Produce statistical specifications including but not limited to analysis datasets, simulations, statistical modeling, integration of biomarker analyses with interpretation, and contribution to abstracts and papers. Develop/maintain analytical clinical tools involving the R shiny package and/or other statistical methods in support of enrollment into clinical trials of neurological diseases.

Some of the statistical tools developed and/or contributed:
    Interactive statistical tool to further the SPARK clinical research study that investigates the effectiveness of BIIB054, a potential drug to treat Parkinson's disease.
  • tidyCDISC
    Application to facilitate the creation of custom tables and figures from ADaM datasets (GitHub link: tidyCDISC).
  • Risk Assessment
    Interactive web application that provides a front end for a collection of metrics for R packages via the riskmetric package. It includes visualizations and comparison metrics. The app is aimed to help in the validation of R packages in the context of regulated industries (GitHub link: Risk Assessment).

RStudio Internship ⋯ Summer 2019 RStudio, Boston, MA
Project: Develop a modeling package (applicable) in R to demonstrate different methods to measure how much a new data point is an extrapolation from the original data. This project builds on applicability domain methods from computational chemistry to create functions that can be included in a dplyr pipeline to perform statistical checks on data in production; Mentor: Max Kuhn (RStudio Summer Interns).

Application Software Developer Analyst ⋯ 2017-2019 University of Florida, CTSI, FL
Work as part of a research support unit specializing in the science of information, in particular, supporting research at all stages with services such as data cleaning, collection, and analysis using R; software (modules) extensions for REDCap using PHP/Python/Javascript; software deployment and maintenance for WebCAMP; local software testing using Vagrant/Docker; Linux servers maintenance (CTSIT homepage).

Researcher ⋯ 2015 & 2013 University of Hawai'i at Hilo, HI
Conducted research in factorization theory as an undergraduate student and returned to the program two years later to guide/instruct a team of undergraduate students throughout the research process. Presented the findings of these two summers at the Joint Mathematics Meetings of January 2014 and 2016.
