Biostatistician with 10+ yrs experience | Survival, Longitudinal & Spatio-temporal Analysis | R, SAS, SPSS, Stata, Mplus

Profile Summary

I am a biostatistician with a PhD in Biostatistics and over 10 years of experience in clinical, epidemiological, and public health research. I am currently an associate researcher at the University of British Columbia. My core methodological expertise spans survival analysis, longitudinal data analysis, spatial and spatio-temporal modeling, Bayesian inference, joint modeling of longitudinal and survival outcomes, structural equation modeling, and latent class/growth mixture modeling. I have authored or co-authored over 70 peer-reviewed publications. I serve as an editorial board member for several journals (including PLOS One, BMC Public Health, and Trials) and as a peer reviewer for 50+ manuscripts, and I'm a co-investigator on several CIHR-funded research projects. I am available for statistical analysis and study design, predictive modeling, manuscript and grant statistical support, and editorial/peer review consulting.
