  • *Psychiatric comorbidity *
    I am interested in examining the familial coaggregation of
    psychiatric comorbidity and the association between psychiatric disorders
    and somatic diseases using Swedish population-based registers and Swedish
    Twin Register.
    *Recovery after cancer surgery*
    I am interested in improving health related quality of life, symptom
    management, and survival after thoracic (esophageal and lung) cancer surgery
    using patient-reported outcome data and register-based data.
    *Methods used in my research*
    My research uses diverse study designs including family study, twin study,
    longitudinal study with repeated measures, randomized controlled trial, and
    qualitative study. I am familial with several advanced statistical methods
    such as multilevel data analysis (e.g., mixed effects model, fixed effects
    regression model, and latent growth curve model), survival analysis, factor
    analysis, structural equation modeling, familial co-aggregation analysis,
    twin analysis, etc. I am good at statistical software STATA, R, and Mplus,
    but also have experience in using SAS and SPSS.
