Research Summary

Most of Gregg Dinse's research focuses on developing improved statistical methods for analyzing data from animal carcinogenicity experiments, multi-chemical toxicity studies, and population-based cancer registries. Several of his recent projects include:

 

  • Comparing temporal and demographic patterns of non-Hodgkin's lymphoma incidence in Pennsylvania with national results from the United States.
  • Summarizing log-linear time trends in cancer incidence and mortality rates in the United States for cancers not related to tobacco, screening, or treatment.
  • Assessing sex and race differences via age-period-cohort analyses of cancers not related to tobacco, screening, or HIV in the United States.
  • Adapting an additive hazards regression model to analyze survival data with some censoring indicators missing at random.
  • Comparing tumor incidence rates in female Harlan Sprague-Dawley rats with those in female Fischer 344/N rats based on NTP historical control data.
  • Employing kernel smoothing techniques to estimate hazard functions when some cause-of-death indicators are missing at random.
  • Adjusting for covariates in a linear regression analysis of survival data when some censoring indicators are missing.
  • Using a rabbit model to study the feasibility of a silver ion delivery device for treating osteomyelitis.
  • Developing statistical methods for comparing tumor incidence rates in current and historical control groups from rodent carcinogenicity bioassays.
  • Fitting a 4-parameter logistic model (or Hill model) to binary dose-response data via an EM algorithm.
  • Characterizing relative potency for chemicals with non-similar dose-response curves.
  • Evaluating the effects of birth weight and early weight gain on pubertal maturation.
  • Using a power model to estimate relative potency.
