Research Interests

Primary focus of research has been the development and application of statistical methods for problems in the areas of clinical trials, occupational and environmental epidemiology and the evaluation of radiological imaging systems. Collaborative efforts in clinical trials have most often been in the areas of colo-rectal cancer and in the treatment of otitis media in children. Methodological research has included development of methods to estimate survival or system reliability. Research in occupational and environmental health has included estimation of cancer risk for various occupational groups including coal miners, steelworkers and aluminum reduction plant workers. Research in the area of radiological imaging systems has included development of methods to improve the design and analysis of radiological imaging systems. This has entailed application and development of methodology in ROC curve analysis. (Health Sciences Faculty Research Interests Project)

Current Research Studies

NIH
ROC Analysis of Imaging Systems Evaluations
Many of the investigations that are now carried out during imaging systems’ evaluations and comparisons include interpretation (reading) studies of normal and abnormal cases that are evaluated using ROC analyses. The purpose of this competing continuation proposal is to develop methodology to apply a well-known statistic to this problem and verify the proposed approach using both simulation and a large set of experimental data.

NIH
Efficacy of Short-Course Antimicrobial Therapy in Young Children with Acute Otitis Media and Impact on Antimicrobial Resistance
AOM remains the most frequently occurring infection for which antimicrobial agents are prescribed for children in the U.S.  Concerns about the development of antimicrobial resistance on the part of pathogens that cause AOM have led to recommendations to withhold antibiotics unless symptoms persist or worsen. Indeed, we are currently studying whether this non-pharmacologic approach is clincally feasible in an NIAID-sponsored randomized, double-masked, trial for which data collection will be completed in early 2009.

NIH
Corticosteroids for Children with Febrile Urinary Tract Infections
Urinary tract infection (UTI) is the most common serious bacterial infection in young children. In approximately 15% of cases, UTI leads to permanent renal scarring. In this study, we will examine two strategies to reduce the incidence of renal scarring in children with UTI.
