Activity of Pancreatic Beta-Cells

Pancreatic beta-cells are located in islets of Langerhans in the pancreas and are the only cells in the body that secrete insulin,
a hormone that is necessary for the uptake of glucose by other cells. Defects in beta-cell functioning lead to diabetes, which can result
in death if not treated. The release of insulin is controlled by many physiological variables, including the cell's electrical activity,
calcium, and nucleotide concentrations. I work in the development and analysis of mathematical models of beta-cell activity as well as
potential methods for islet syncrhonization.

The Neural Basis of Chemosensing

Humans and other animals sense their environment in a number of ways, including responding to molecules in the air or on the tongue. This
This sensory mechanism is referred to as chemosensing. I collaborate with two experimental labs and a number of fellow mathematicians to use
mathematical modeling and data analysis to understand how taste information is coded in the olfactory bulb and how odor information is coded
in the gustatory cortex of the brain.

Bursting Oscillations in Excitable Cells

In nerve cells, information is transmitted through electrical impulses. Electrical impulses also cause muscles to contract and endocrine cells
to secrete hormones. Quite often, impulses are generated as high-frequency bursts, followed by periods of quiescence. This is particularly true in
endocrine cells such as pancreatic beta-cells and pituitary cells. I am interested both in the dynamics of bursting (a mathematical topic) and in
the mechanisms by which different cells generate periodic bursts of impulses (a biological topic).

Biological Networks

Many biological systems can be described as networks of interacting parts. I study networks of neurons and hormone-secreting endocrine cells, as well
as gene transcription networks. This research uses techniques from network science, statistics, and data science. Application areas include the olfactory
system, the gustatory system, hypothalamic neurons, and the study of the disease sepsis.
