Numerosity Perception and Numerical Cognition

At the CoDeNeuro Lab, we are studying several aspects of numerosity perception and numerical cognition, ranging from basic perceptual abilities – like approximately estimate sets of items – to more complex mathematical skills, as well as the intertwining between perceptual and cognitive processes. Moreover, beside studies on adults, we are also performing experiments on young children, to study how the developing brain acquires numerical and mathematical skills.

iPads and Children's Attention Networks (iCAN)

This project, iPads and Children’s Attention Networks (iCAN), will examine the ways in which young children's attention can be affected by tablet play in comparison to regular toy play. We are seeking RAs to help recruit participants, run the experiment, and enter collected data. New RAs will be trained in recruitment processes, procedures for running participants, SPSS statistical software analyses, and electrophysiological data (i.e., EEG) collection and analyses.

Exploring the Diversity of Wood-warbler Singing

Birds of many species in the wood-warbler family use their songs in especially interesting ways. For example, their songs fall into two categories, and the two kinds of songs are used in different contexts, vary over time and space in different ways, and have different functions in communication. However, although many species in the family share this two-tiered singing system, species differ in the sizes of their song repertoires, how the difference between the two categories is encoded, how song form varies within a population, how songs change over time, and so on.

Insect antimicrobial peptides and novel ways to control flies

In 2011, Jules Hoffmann received the Nobel Prize in Physiology/Medicine for his research on antimicrobial peptides in the common fruit fly, Drosophila melanogaster. This was significant research because antimicrobial agents used in human medicine are often no longer effective. Microbes have developed resistance to many of our current antimicrobials. Hoffmann’s research was significant because now researchers had access to a variety of new antimicrobials never before used against human pathogens.

Hormone-Behavior Responses to Chronic Stress

Research in the Meyer lab focuses on the relationships between hormonal and behavioral responses to stress, especially chronic or long-term stress. Stressful events trigger the adrenal glands to secrete several hormones, including epinephrine (adrenaline) and cortisol, into the bloodstream. Over periods of weeks to months, circulating cortisol is incorporated into keratin-containing tissues like hair and fingernails, where the hormone can be measured as a biomarker of long-term adrenal secretory activity.

Emerald Ash Borer Technician

I am seeking a motivated student interested in conservation, ecology, or entomology to work with me on field and laboratory studies focused on controlling the invasive insect, the emerald ash borer. Since its discovery in Michigan in 2002, the emerald ash borer (EAB) has spread to 25 states in the US, killing millions of native ash trees. Management of EAB now focuses on biological control through the use of three introduced parasitoids that specialize in destroying EAB.

Designing genetic markers to identify Brachypodium species

Brachypodium distachyon is a premier model species for biologists working with grasses. However, B. distachyon is difficult to distinguish morphologically from two other species: B. staceii and the hybrid tetraploid, B. hybridum. This has made expanding the breadth of B. distachyon collections from the wild very difficult, hindering the development of resources for this species. Professors Caicedo (Biology), Hazen (Biology) and Tyler (BMB) have a large collection of Brachypodium spp.
