Linda Levin
Linda, Levin


Research Assistant Professor 558-0050
As a biostatistician, my focus has been the study of methodologies for analyzing longitudinal discrete and continuous data, and investigation of the effect ofmeasurement error and misclassification on estimates of association between environmental exposure and respiratory health.

Specifically, an area of interest in longitudinal analysis is the assessment of pulmonary function change over time. As chief statistician in a large
industry-wide study of the effect of an occupational exposure, I have computerized spirometric trend reports which are being used to measure
pulmonary function change for large numbers of workers. I have co-authored many publications in which longitudinal data analysis was used, including
Generalized Estimating Equations and mixture modeling approaches.

Extensive experience in exposure modeling has led to research on quantifying measurement error and determining its effect under various statistical models on estimating health effects.

Currently I am teaching a graduate level course called Categorical Data Analysis. These methods are used to analyze binary (yes/no) outcomes such as disease presence/absence, as well as categorical data.

Our research is focused on developing and applying computational approaches for data mining, analysis and knowledge extraction from biomedical data. In particular, we are active in the fields of structural bioinformatics, computational genomics and systems biology. For example, we have recently developed a number of novel methods for analysis and predictions of protein interactions, including those for membrane proteins, and for model quality assessment. We are also pursuing development of improved methods that combine docking simulations, chemical similarity and toxicogenomics in order to predict activity of environmental factors and other small molecules. We are applying these methods in the context of collaborative projects with colleagues in DEH and other departments of the UC College of Medicine and beyond, with some recent examples illustrated by collaborative papers listed below. Based on recent methodological advancements, we are also developing bioinformatics tools, e.g., for functional and structural annotation of proteins and their complexes. Several of these tools, including SABLE, SPPIDER, and POLYVIEW-3D, are available to the community as web servers and are being widely used by researchers from many countries.
