The MICDE PhD Student Seminar Series showcases the research of students in the Ph.D. in Scientific Computing. These events are open to the public, but we request that all who plan to attend register in advance.

Temporal relationship between acute noise exposure and heart rate variability change

Excessive noise in daily activities and during sleep is disturbing and causes annoyance and stress over time. Noise, among numerous environmental pollutants, also independently contributes to the risk of cardiovascular diseases potentially through stress responses. Heart rate variability (HRV) change, which reflects the neurohormonal and automatic neural responses to stress, has been evaluted as an outcome to air pollution (PM 2.5, ozone), smoking, and other exposures. This analysis explored feasibility of using time series analysis to examine the noise and HRV association in a large longitudinal cohort. Alternative modeling approaches were also explored to accommodate the complex structure of this time series data.

Xin Zhang, EHS and Scientific Computing

Xin Zhang is a 3rd year PhD candidate in the Department of Environmental Health Sciences at the University of Michigan. Her research focuses on evaluating the effects of environmental noise exposure on auditory and cardiovascular health outcomes using integrated data from personal devices with wearable sensors.
