ABOUT ME

Dr Leong completed her PhD in statistics and applied probability in 2014 at University of California, Santa Barbara where her studies focused on survival analysis. Survival analysis is generally defined as a set of methods for analyzing data where the outcome variable is the time until the occurrence of an event of interest, such as death, occurrence of a disease, marriage, divorce, etc. She is currently doing work on middle-censoring, a very general censoring scheme where the actual value of an observation in the data becomes unobservable if it falls inside a random interval (L,R). Her recent paper discussed discrete lifetime data where covariates are present under middle-censoring. Her other research interests include work on biostatistics and applied statistics. She is also a graduate from the University of Manchester and holds a MSc in Statistics in 2007. She received her bachelor’s degree in mathematics from Universiti Brunei Darussalam in 2005.
