Longitudinal Modeling of Craniofacial Growth Trajectories

PD/PI: Nahhas RW
Co-I: Sherwood RJ
Funding Agency: NIH NIDCR
Dates: 04/01/2011–01/31/2014

The goal of the proposed research project is to precisely characterize ontogenetic trajectories across the functional/developmental components of the craniofacial complex throughout childhood and into young adulthood. This project will result in a web-based application, useful for both clinicians and basic researchers, which will provide sex- and age-specific benchmarks for the normative range of craniofacial growth and development.


Genetic Architecture of the Human Dentognathic Complex

PD/PI: Sherwood RJ
Co-Is: Duren DL, Towne B
Funding Agency: NIH/NIDCR (R01DE018497)
Dates for Award: 05/18/2009–03/31/2014

The ultimate objective of this project is to elucidate fundamental aspects of the genetic architecture of the human dentognathic complex. Quantitative data from the dentition, mandible, and maxilla will be collected from the Jirel population of eastern Nepal. Heritability of each trait will be estimated, and genetic and environmental correlations matrices will be examined for all traits. Additionally this project will seek to identify chromosomal regions (quantitative trait loci; QTL) harboring genes that influence variation in dentognathic measures.


Opioid Use Trajectories and HIV Risk Among Young Adults in Ohio
PD/PI: Carlson RG, Falck RS
Co-Is: Daniulaityte R, Nahhas RW
Funding Agency: NIH/NIDA (R01DA023577)
Dates of Award: 04/01/2008–03/31/2013

The goal of this proposed study is to describe trajectories of non-prescribed pharmaceutical opioid use and identify the factors associated with the development of DSM-IV abuse or dependence on pharmaceutical opioids (and transition to heroin use) among people aged 18-23 years old.


Short-term Training for Minority Students Program
PD/PI: Chumlea WC
Mentor: Duren D
Funding Agency: NIH/NHLBI
06/01/2010–05/31/2015

The major goal of this project is to give short-term training in the cardiovascular sciences with emphasis on basic mechanisms of cellular and neural physiology, cardiovascular and endocrine control/epidemiology to minority undergraduates.


Post Baccalaureate Research Education (PREP)
PD/PI: Chumlea WC
Mentor: Duren D
Funding Agency: NIH/NIGMS
Dates: 03/01/2010–02/28/2014

Supports the research training and education of recent baccalaureate graduates from groups underrepresented in biomedical and behavioral research areas, who plan to pursue Ph.D. degrees. This research apprenticeship serves as an educational transition for recent baccalaureate graduates who will acquire essential academic credentials and research skills to make them more competitive for Ph.D. programs at highly selective institutions.
