Takeda

Bio

As a statistician on Takeda’s Quantitative Sciences team in Boston, MA, I focus on statistical modeling and analysis of data from digital devices such as wearable accelerometers, ambulatory blood pressure monitors, respiratory monitors, and polysomnography. My recent projects involve digital assessments in hypersomnolence disorders and ALS.

Before joining Takeda, I was a postdoctoral researcher at the Onnela Lab at Harvard T.H. Chan School of Public Health. I received a PhD in Biostatistics from Johns Hopkins Bloomberg School of Public Health in 2021, and hold Bachelor’s and Master’s degrees in Mathematics from Wroclaw University of Science and Technology, Poland.

In my leisure moments, I find joy in connecting with people, running, and hiking. The peak of my running tenure was probably finishing a full marathon in 2017. Currently, I am working on summiting New Hampshire’s 48 peaks over 4,000 feet. Some summits photos can be found in my 🌄 gallery.
