Probing the propensity of soil bacteria for couch-potatohood

The DeAngelis lab is looking for two students to help with a project looking at what makes soil bacteria decide to behave like slobs rather than lean mean growing machines. Students will measure optical density and carbon dioxide concentrations, in addition to preparing growth media. Students should be reliable and conscientious workers, show attention to detail even when faced with repetitive tasks, able to follow instructions, have neat handwriting, and work at a reasonable pace.

Discover genes driving cell migration in the frog-killing chytrid fungus

The chytrid fungus Batrachochytrium dendrobatidis (Bd) causes an infection that is devastating amphibian populations world-wide. We have recently discovered that this fungus can migrate (crawl) like an amoeba during a few hours of its lifecycle, potentially during amphibian infection. To learn more about crawling by chytrid fungi, our recent paper can be found here: http://jcb.rupress.org/content/216/6/1673

Using cutting edge microscopy to study high-speed cell migration

Cells within your own body crawl over surfaces and through three-dimensional environments. Some cells crawl slowly, while others crawl very quickly. Conventional microscopy is good for imaging slow-moving cells on flat surfaces but cannot keep up with white blood cells like neutrophils that migrate a thousand times faster through 3D environments. To understand how high-speed cells interact with and crawl through complex environments, we use cutting edge lattice light sheet microscopy that has the necessary speed and resolution to image fast-moving cells and complex environments.

Using zebrafish to understand the developmental origins of disease

The Timme-Laragy lab uses the zebrafish and cell culture to understand how embryonic exposure to pollutants affects embryonic development and later-life health outcomes. We have ongoing projects examining the effects of phthalates, perfluorinated compounds, and PCBs on pancreas and liver development, and are investigating toxicant effects on later-life metabolic diseases. We anchor these morphometric and metabolic outcomes with experiments probing the antioxidant defense system and the Nrf2 signaling pathway.

Characterizing cell wall mutants in the model grass B. distachyon

Grasses represent some of the most agriculturally and economically important plant species around the world. Cereals are a cornerstone of food security, and several high biomass grasses are candidate biofuel crops. Understanding the genetic factors that regulate growth dynamics in grasses is key to bettering our ability to improve and implement these important crops species. In the Hazen lab, we study the transcriptional regulation of secondary cell wall biosynthesis in the model grass Brachypodium distachyon.

Lab Librarian

Our laboratory uses DNA sequences and morphological characters to investigate the diversity, evolution and ecology of armored scale insects (class Insecta: order Hemiptera: family Diaspididae), especially in tropical rainforests. We discover many undescribed species from around the world. The lab librarian is responsible for managing the lab's diverse array of interconnected information resources.

Armored scale insect systematics

Our laboratory uses DNA sequences and morphological characters to investigate the diversity, evolution and ecology of armored scale insects (class Insecta: order Hemiptera: family Diaspididae), especially in tropical rainforests. Paid lab assistantships are available for students to prepare DNA and microscope slide mounts from individual armored scale insect specimens. For advanced students, independent research projects are also possible.

Adventures in root growth

I am looking for a motivated undergraduate to help us with our experiments on the growth of plant roots. For the moment, tasks will be physiologically based, measuring elongation rate, root diameter, and some other parameters. Some methods will use basic light microscopy. Molecular experiments are likely, in the future. Some work managing plant growth and seed harvet to maintain our lines will also be involved. As the student gains experience in the lab, they will get to take on their own project. Previous lab work is not necessary.
