Most animals on Earth obtain their energy from green plants, and, thus, it is not surprising that interactions between plants and animals have played a prominent role in our current understanding of how ecological processes such as predation, parasitism, and mutualism shape evolutionary patterns in plants and animals. The main topics that we will discuss in this seminar include pollination, fruit and seed dispersal, deception, herbivory, and phytocarnivory, considering both ecological and evolutionary perspectives.

Plastic changes to synapses are thought to underlie many higher order functions of the brain in both the developing and adult nervous system. Knowledge of the underlying molecular mechanisms of synaptic plasticity is critical to understanding the complex functions of the brain to which these changes contribute. This seminar course will primarily focus on the most well-studied example of synaptic plasticity, synaptic modifications in a region of the brain called the hippocampus. These changes are thought to underlie our ability to learn and remember.

(Offered as PHYS 400, BIOL 400, BCBP 400, and CHEM 400) How do the physical laws that dominate our lives change at the small length and energy scales of individual molecules? What design principles break down at the sub-cellular level and what new chemistry and physics becomes important? We will answer these questions by looking at bio-molecules, cellular substructures, and control mechanisms that work effectively in the microscopic world. How can we understand both the static and dynamic shape of proteins using the laws of thermodynamics and kinetics?

A study of the architecture and interactions of genetic systems. Advances in genomics are providing insights into a variety of important issues, from the structural limits of DNA-based inheritance to the discovery of novel infectious and genetic diseases. We will address how heritable information is organized in different groups of organisms. We will also cover a major challenge of this emerging field—the application of vast amounts of genetic data to understanding genomic integrity and regulation.

(Offered as CHEM 330 and BIOL 330) What are the molecular underpinnings of processes central to life? We will explore the chemical and structural properties of biological molecules and learn the logic used by the cell to build complex structures from a few basic raw materials. Some of these complex structures have evolved to catalyze chemical reactions with an enormous degree of selectivity and specificity, and we seek to discover these enzymatic strategies.
