Ronald Benner
My research focuses on the carbon, nitrogen, and phosphorous cycles in aquatic environments. Experimental approaches are used to characterize biogeochemical processes and the roles of microorganisms as key players in the transformations of C, N and P, and geochemical approaches are used to integrate processes over space and time.
Carol Boggs
Evolutionary & physiological ecology, conservation biology.
Beth Krizek
We are interested in defining the molecular mechanisms by which a small number of pluripotent floral stem cells develop into a mature Arabidopsis flower.
Sofia Lizarraga
The Lizarraga laboratory primary focus is to understand the basic molecular and cellular mechanisms that contribute to neuronal circuit formation during normal brain development and in disease associated conditions. Using human stem cell models, we investigate common biological mechanisms underlying the pathobiology associated with disorders of neuronal connectivity.
Fabienne Poulain
My lab aims to understand the cellular and molecular mechanisms for axon pathfinding and selective degeneration leading to the formation and maintenance of functional brain circuits. We use zebrafish as a model system and a unique combination of genetic, embryological and live imaging approaches to observe and manipulate axons directly in the embryo in vivo.
Ryan Rykaczewski
Biological Oceanography, Fisheries Oceanography, Ocean Biogeochemistry, Pelagic Ecology, Global Change
Daniel Speiser
The Speiser Lab studies the structure, function, and evolution of complex traits in invertebrate animals. We are particularly interested in the function and evolution of dispersed sensory systems in marine molluscs, particularly the multi-eyed visual systems found in certain bivalves (such as scallops) and in certain species of chiton. We are also studying the neurobiology that underlies these distributed sensory networks. As a hypothesis-driven research group, we are open to pursuing a wide range of questions in visual ecology, marine biology, and evolutionary physiology.
