Valenzuela Lab

In the Valenzuela lab of Evolutionary and Ecological Genomics, we are interested in studying how ecology affects the structure, function, and evolution of the genome and its role in the development and evolution of complex phenotypes. This helps us understand the evolution of biological diversity and how it responds to environmental change. We have two main research foci:

SEX DETERMINATION
Why do organisms vary so remarkably in the ways they produce males and females? Our work focuses on comparative evolutionary and ecological genomics related to the evolution of developmental pathways, particularly those that underlie the development of the sexual phenotype.

PHYLOGENOMICS
What are the causes and consequences of chromosome evolution? We are studying (a) the evolution of sex chromosomes and the genes they contain, plus (b) the genome rearrangements responsible for changes in diploid number across turtles and their association with transitions in sex determination.

Lu Lab

My lab’s research integrates ground/satellite observations into process-based ecosystem modeling framework to examine how land ecosystem processes and functions responded and will respond to human activities (e.g., anthropogenic climate change, air pollution, land use and management, etc.) and natural disturbance. Our research topics include coupled biogeochemical and hydrological cycles, ecosystem productivity and carbon sequestration capacity, water and nutrient use efficiency, land-atmosphere exchange of greenhouse gases (CO2, CH4 and N2O), and land-to-aquatic mass exchange at multiple scales ranging from watershed, regional, continental to global. Our work involves mathematic modeling, large-scale data development, data-model integration, geospatial and statistical analysis. Overall, it can serve as a powerful tool for hindcasting and forecasting the provision of ecosystem goods and service, and identifying better management practices and mitigation options for a sustainable earth.
