I am a first year graduate student in the Brown/MBL program, working under the direction of Dr. Stephen Porder and Dr. Christopher Neill. I am interested in carbon and nitrogen cycling related to land use and climate change. This summer I went to Puerto Rico and worked on a project looking at net nitrogen mineralization on a topographic gradient on two different types of soil. For my dissertation I plan to work on the PIRE project in Sub-Saharan Africa. Mainly, what are the environmental consequences of the Green Revolution in Africa and how can we best manage the land to provide sufficient calories to those who need them while preserving the environment? I spent the last two years working in Dr. Whendee Silver’s lab at UC Berkeley where I participated primarily in projects looking at carbon sequestration in rangelands, greenhouse gas dynamics in response to a hurricane simulation, and redox dynamics in tropical forests. As an undergraduate I worked as a research assistant in plant ecology and entomology.

I study the ecology of microbial communities and how the diversity of microbes varies over geographic distance. My research has two main themes: 1) Using DNA sequencing and fingerprinting methods, I track the allelic variation of sulfate reducing enzymes within and between east coast salt marshes. 2) I study the biofilm structures of hydrothermal vent bacteria and their methods of communication and dispersal.

My current research focuses on how fish power suction feeding, the dominant feeding mode among the over 25,000 species of ray-finned fish. Suction feeding relies on explosive expansion of the mouth cavity to accelerate water and prey into the mouth. The power required for this expansion may be produced largely by axial body muscles. To measure axial muscle strain and skeletal kinematics during suction feeding, I am using XROMM (X-ray Reconstruction of Moving Morphology) of feeding in Largemouth Bass. These data will allow me to investigate how this diverse group of vertebrates uses skeletal kinematics and muscular power to expand the mouth during suction feeding.

I am interested in the biomechanics and evolution of flight in dinosaurs, with particular emphasis on Archaeopteryx. Methods of investigation include 3D x-ray imaging of fossil and extant archosaurs, XROMM, and computer animation. Other research projects include reconstructing the feather color of Archaeopteryx and a GIS-based early warning system for predicting epidemics of vector-borne diseases such as dengue and West Nile virus.

Jorn's work involves the functional morphology of the wing membrane of bats, which contains both passive structural elements as well as active muscular elements. He is interested in modeling the behavior of these elements on the mechanical properties of the wing membrane in an effort to better understand how they shape the wing in flight.

(Thesis title: "Salt Marsh Mosquito Ditches on Fire Island, NY: Sedimentation Rate, Nekton Community and Implications for Restoration")

I am interested in how salt marshes will respond to global climate change. My dissertation research is focused on growth and phenology in Spartina alterniflora in marshes along a the east coast from Massachusetts to South Carolina.

I am interested in the developmental trade-offs associated with animal form and function. Young vertebrates enter the world at many different levels of morphological maturity (e.g., humans vs. horses) and display an array of developmental strategies taking them into adulthood. I would like to understand how developmental strategy influences locomotor performance of both juvenile and adult forms. In the past I've primarily worked on developing birds (mallard ducks and chukar partridge), but am now branching out to the ectothermic world, which arguably exhibits the most interesting morphological and life-history variation.

My interests include plant systematics, desert floras, and the effects of rapid environmental change on ecosystems. After working on the systematics of desert Phacelia species for my master's thesis, I am looking forward to studying the ways that phylogenetic information can help predict plant responses to climate change. I will be investigating using plant functional traits and biogeochemistry to bridge the gap between phylogenetics and studies of global climate change.

I study adaptations to unpredictable environments that are continually changing, thereby causing the fitness of a trait to vary through time. I address this problem with a combination of analytical and computational modeling as well as experimental evolution in fast evolving microbial organisms. Current projects of mine include applying the theory of selection in varying environments to problems in infectious disease evolution and experimentally evolving laboratory populations of yeast in an unpredictable environment.

In both developmental biology and evolutionary theory scientists aim to understand how life changes through time. I am interested in understanding the dynamic between evolution and development. How is development shaped by evolution and vice versa? How tightly linked are specific developmental processes with phenotypic outcomes? How do developmental and evolutionary transitions occur? To this end, I am focusing on a group of organisms called cnidarians (jellyfish, corals, siphonophores, Hydra). This group represents an excellent opportunity to address these questions due to its incredible developmental and phenotypic diversity. I use molecular and embryological techniques to explore developmental dynamics and evolution within this fascinating lineage.

Emily Hollenbeck

Start: Fall 2012

Many species have been observed moving up in elevation as well as latitude in response to warmer climates. I am interested in altitudinal range shifts occurring under current and future climate change. Steep mountains provide a spatially rapid gradient of environmental conditions and community assemblages, which could potentially mean much shorter (and easier) shifts in order for species to reach an ideal climate. However, climate change in many locations is more complex than a simple rise in temperature, and both biotic and abiotic mismatches may impact species’ fitness in a new location. I hope to explore the fitness consequences of range shifts from various angles, including population genetics, local adaptation, and physiological ecology.

I am generally interested in the biomechanics and evolutionary history of terrestrial locomotion in vertebrates. I concentrate particularly on theropod dinosaur and avian locomotion. Currently I am working on a project involving kinematics and kinetics of guineafowl locomotion as well as a series of projects investigating joint construction and diversity within birds and theropods. My previous work was in morphometrics and multivariate methods for correlating locomotor habits and foot morphology.

I am interested in the forces that shape natural microbial communities and how these in turn impact ecosystem function. My current research focuses on the marine microbial communities of the Western Antarctic Peninsula, a region that undergoes extreme light-driven seasonal transitions. I plan to examine how these transitions, especially spring sea-ice melt and phytoplankton blooms, drive changes in bacterial diversity and activity.

My research will focus on nutrient limitation and productivity in two areas of Brazil with very different land use histories: the Atlantic Forest and the Amazon. The former has a much longer history including multiple periods of use and abandonment, while the latter has experienced rapid, widespread change in the last several decades. I am particularly interested in the biogeochemical cycles of secondary forests and how these cycles have been influenced by the duration and intensity of past land use.

For my Master’s thesis, I examined the effects of urbanization on carbon storage in soils and vegetation near Apalachicola Florida using a combination of field sampling, GIS, and remote sensing. Other recent projects have explored how changes in forest cover in the southeast US alter stream water quality and hydrology.

I am interested in the effects of domestication on locomotion and its implications for morphological changes, performance and the structural organization of muscle. Artificial selection has lead to faster growth in order to decrease time to market and large increases in muscle mass in some species. I am using the turkey to examine these relationships by comparing wild, heritage and broad breasted white breeds.
