About Me

I am a PhD candidate in Biostatistics at Schulich School of Medicine & Dentistry, University of Western Ontario (UWO), under the supervision of Dr. Osvaldo Espin-Garcia and Dr. Yun-Hee Choi. I completed an MSc in Biostatistics at Western and an Honours Bachelor of Science degree at the University of Toronto with majors in Mathematics and Statistics. My research interests combine methodology development and applications, especially two-phase sampling for next generation sequencing data, missing data in family-based studies, statistical genomics, clustered data, and applied health data science. I enjoy collaborating with multidisciplinary scientists to deliver effective and statistically grounded solutions. I find pleasure in solving biostatistical challenges and have a long-term objective to secure an academic role, collaborating with diverse professors and industries.

Some Lecture Notes

STA450: Statistical Methods for Emerging Infectious Disease Management Free

Typesetting final review notes for STA450 instructured by Prof. Patrick Brown. This course has some common knowledge with STA442 so you may find it's useful for STA442 as well. Almost covered all materials of STA450 that is possibly going to be tested on final exam, but I am not TA nor instructor so don't blame me if something is not covered.
