Hi, I'm Margaret!
I am a PhD Candidate in Biostatistics at the University of Michigan. My research focuses on Accelerometry Data, particularly developing new methods to analyze Physical Activity and Sleep Data in free-living populations.
An East Coast transplant, I have lived in Ann Arbor now since 2015 - and love it (Go Blue!) Outside of working, I enjoy hiking, bookstores, coffee shops, and visiting my family.

Research and Experience
Graduate Method Research
University of Michigan, 2016- present
My dissertation research focuses on method development for analyzing Accelerometer Data, both in terms of Physical Activity and Sleep. I joined the Peter Song Lab as well as the ELEMENT (Early Life Exposures in Mexico to ENvironmental Toxicants) group for this dissertation research. I have shared my work at ENAR and JSM poster presentations in 2019 and 2018.
Graduate Applied Research
University of Michigan, 2016 - present
From 2016 to present I have worked with the Early Life Exposures in Mexico to ENvironmental Toxicants (ELEMENT) group, which is a cohort birth study in Mexico City spanning two decades and three generations. With this group I work on wide-range of data, including:
-
Metabolomics Data
-
Accelerometer Data
-
Toxicant Exposure Data
-
Cognitive Neuro Data
Graduate Teaching Experience
University of Michigan, 2015
In 2016 I was a Graduate Student Instructor (GSI) for the undergraduate Statistics course (Stat 250) taught within the University of Michigan.
Financial Analyst
GE Healthcare, 2012-2015
Prior to returning to graduate school, I worked as a Financial Analyst with GE Healthcare.
-
I began as part of the Financial Management Program (FMP), which is a two-year rotational leadership program with concentrations in Controllership, Financial Planning & Analysis, Corporate Strategy and Operational Efficiency; the program combines 4 intensive job assignments with demanding coursework in finance and accounting.
-
Upon completing the FMP program, I accepted a position as a Global Supply Chain FP&A Analyst
