This summer, Xuanxuan Yu will complete his third degree in biostatistics, but there was a time as an undergraduate
when he didn’t have a clear understanding of the field. In his bachelor’s program
at Nanjing Medical School in the Jiangsu Province where he grew up, Yu fell in love
with the subject.
“I gradually learned that statistical methods play an important role not only in public
health but also in human health and other socioeconomic fields,” he says. “This encouraged
me to pursue knowledge in the interdisciplinary realms of statistical methods to get
close to the genuine understanding of world’s mechanisms.”
As the hotspot is moving from statistical methods for data of small samples to large
samples, I chose to focus on the field of statistical genetics and genomics. Moreover,
discoveries in genetics and genomics lay a crucial foundation for advancing treatments
to improve human health in the future.

After completing a master’s degree at the same institution, Yu chose the Arnold School’s
Department of Epidemiology and Biostatistics for his doctoral degree – both for its reputation and the research interests he shared
with his mentor, Feifei Xiao. During his program, Yu gained research experience on
various projects, developing expertise in the development and application of statistical
methods for analyzing multi-omics data, such as methylation data, gene expression
data, and sequencing data.
“As the hotspot is moving from statistical methods for data of small samples to large
samples, I chose to focus on the field of statistical genetics and genomics,” Yu says.
“Moreover, discoveries in genetics and genomics lay a crucial foundation for advancing
treatments to improve human health in the future.”
As his advisor and mentor, Xiao not only helped Yu navigate his doctoral program,
she also helped him keep his perspective. One takeaway for Yu was the importance of
reviewing existing methodologies and then building on them with innovative approaches
that overcome limitations yet capitalize on their strengths. Another lesson involved
how to balance attention to minute details while maintaining a focus on the big picture.
After graduating in August, Yu will continue his training with a postdoctoral associate
position in the Department of Surgery at the Sepsis and Critical Illness Research
Center. He envisions a long career dedicated to the development of statistical methods
that improve public health and other areas that impact quality of life.
