A Mechanism and Pro-migratory Function for Non-canonical TGF-beta Signaling through Smad1 and Smad5
(2008-12-10)During the course of breast cancer progression, normally dormant tumor-promoting effects of transforming growth factor-beta (TGF-beta) including migration, invasion, and metastasis are unmasked. Although this switch or ... -
Cities and Labor Market Dynamics
(2012)People live and work in local markets spatially distinct from one another, yet space is absent from most economic models of the national labor market. Workers choose the markets in which they will participate, but there ... -
Distinct Functions and Regulation of Nonmuscle Myosin II Isoforms a and B in Cell Motility
(2008-04-23)The ability of cells to migrate is of fundamental importance to a diverse array of biological processes, both physiological and pathological, such as development, the immune response and cancer cell metastasis, to name a ... -
Do Migrants Degrade Coastal Environments? Migration, Natural Resource Extraction and Poverty in North Sulawesi, Indonesia.
(Hum Ecol Interdiscip J, 2005-06)Recent literature on migration and the environment has identified key mediating variables such as how migrants extract resources from the environment for their livelihoods, the rate and efficiency of extraction, and the ... -
Enhancing Dendritic Cell Migration to Drive Antitumor Responses
(2017)The histologic subtypes of malignant glial neoplasms range from anaplastic astrocytoma to the most deadly World Health Organization (WHO) Grade IV glioblastoma (GBM), the most common primary brain tumor in adults. Over ... -

Job Search and Migration in a System of Cities
(Economic Research Initiatives at Duke (ERID), 2016-12-07)We build an equilibrium job search model, where workers engage in both off- and on-the-job search over a set of cities, to quantify the impact of spatial matching frictions and mobility costs on the job search process. Migration ... -
Location Choice and the Value of Spatially Delineated Amenities
(2008-04-25)In the first chapter of this dissertation, I outline a hedonic equilibrium model that explicitly controls for moving costs and forward-looking behavior. Hedonic equilibrium models allow researchers to recover willingness ... -
Migration and development in Ethiopia: Exploring the mechanisms behind an emerging mobility transition

(2013)Objectives:The objective of this study is to determine the malaria risk among children and adolescents from early married families in the Peruvian Amazon. We will explore the hypotheses that younger maternal age of marriage, ... -
Population Genetics of Species Associated with Deep-sea Hydrothermal Vents in the Western Pacific
(2012)Genetic diversity, population structure, and connectivity influence interactions among communities and populations. At hydrothermal vents in the western pacific, population structure in vent-associated species could occur ... -
Role of the Type III TGF-beta Receptor Cytoplasmic Domain in Breast Cancer Progression
(2009)Breast cancer remains among the most common cancers of the developed world. Despite advances in treatment modalities, deaths due to breast cancer are the second leading cause of cancer death among women. The transforming ... -
The Gaze of “Chaos”: Temporal-Spatial Migration and Power Dynamics in a Globalizing Post-Socialist China
