Professional details
Keywords coping with multilevel/complex structures in outcomes with respect to clustering
multiple & composite discrete endpoints
modelling longitudinal bio markers measured with error and/or are missing
Areas of expertise -Development of prognostic models, validation and updating and promote the standardization of advanced and complex analytical procedures so that these can be implemented routinely.
-Modelling biochemical markers measured longitudinally with multiple “values” measured above or below the limit detectable by the assay.
-Understanding composite outcomes; identification of patterns / associations between multi-dimensional outcomes.
-Methods for accounting for the effect of surgeon on outcome; operations by the same surgeon are not independent and a series could include cases where the surgeon was learning an established technique or refining / developing a new procedure.
-Evaluating alternative methods for controlling for confounding in observational studies.
-Multi-level modelling of data with hierarchical structure such as those arising from data from multiple vessels / grafts from the same patient.
