Population genomics is the study of the structure, function, and variability of the entire genetic complement of organisms considered on a population scale. By examining how gene variants change in structure and frequency in populations over time, we can study the process of evolution and how it contributes to biodiversity and the formation of new species; this information can be used to increase the efficacy of conservation efforts. By studying gene variants underlying diseases at the scale of populations, we can better diagnose complex polygenic diseases like cancer. This course introduces the fundamentals of population genomics and provides an overview of the subfields of evolutionary genomics, conservation genomics, and medical genomics. This course is offered in summer terms only.

The development of all animals relies on the precise migration of cells to their correct locations within the developing body. Among these crucial cell types are germ cells, which ultimately give rise to sperm and oocytes. The migration of these cells is orchestrated by proteins that facilitate cell communication and provide guidance during their journey.In this course, we will delve into the role of mRNA localization in facilitating germ cell migration. Specifically, we will identify mRNAs that code for proteins essential for cell-to-cell communication and cell migration.Through a combination of theoretical learning and hands-on laboratory experiences, students will gain insight into the mechanisms underlying germ cell development. Experimental investigations will allow us to test hypotheses generated during class discussions. At the culmination of the course, students will present their experimental findings in the form of a poster, providing an opportunity to showcase their understanding and contributions to the field.

First Year Seminars
This First-Year Seminar is designed to introduce students to the fundamental physical and chemical origins of color and how we perceive them - from the vivid palette provided by the natural world to the brightly colored clothing we wear. Beginning with the basic principles of light and color, we will embark on an interdisciplinary investigation of color, including, but not limited to: color chemistry; color in biology; the physiology of the eye; how color affects human psychology; the history of color and light; and the use of color in art. Discover the physical and chemical explanations behind several noteworthy phenomena such as sunsets, color-blindness, rainbows, fireworks, chameleons and the Aurora Borealis.
This First-Year Seminar will explore the neuroscience of choice. In addition to exploring the neurobiology of choice, we will dabble with philosophical ideas of free will and determinism. We will also touch on questions related to culpability. For example, are people who break the law but suffer from brain damage responsible for their actions? Sound interesting? Well, why stop there? Let’s sit back, eat some popcorn and take a look at how popular culture depicts the neuroscience of choice in the movies. Yes, with your help, we can do it all – but will you choose to???
Most people think the strongest kind of evidence in a criminal case is a confident eyewitness. Most students think re-reading textbook materials or class notes is the best way to prepare for an exam. And all too many people think that measles vaccines cause autism. All three of these ideas are wrong. In this First-Year Seminar, we will explore what modern psychology has uncovered about how our intuitions concerning human nature deceive us, and lead to incorrect ideas such as the ones just mentioned. We will discuss a wide variety of topics including “the attention economy,” groupthink, and subliminal perception.
We often think of bacteria in the context of dangerous or annoying infections. However, bacteria themselves can be infected by even smaller and more abundant entities: viruses called bacteriophages. This First-Year Seminar will combine readings and discussion of the fundamental biology of phages and their role in controlling populations of bacteria, with lab work to discover new phages from the Johns Hopkins campus. Phages identified in this class will be added to the Science Education Alliance’s archive which is comprised of phages from over 100 academic institutions worldwide and is a resource for phage biologists and physicians directly involved in developing phages as a treatment for disease.
This First-Year Seminar will explore seminal ideas in macroevolutionary theory through both classic and cutting-edge studies. Topics will include the relationship between evolution and development, how fossils shape our understanding of biological systems, and the logical basis of evolutionary inference. Students will also gain an appreciation for the historical development of these ideas and their application in modern science and beyond. This course will explore these topics using foundational texts in biology, such as The Origin of Species and writings by the evolutionary biologist Stephen Jay Gould. It will feature guest lectures from curators from natural history museums across the country as well as offer students their own opportunity to go into the field to collect fossils here in Maryland.

In the age of Molecular Biology, DNA sequencing allows the identification of genes. Biochemical assays allow the measurement of gene expression. Reverse transcriptase and PCR are used to determine the RNA made by activated genes. These tools allow the study of disease organisms on the molecular level with emphasis on particular genes, known as virulence genes, which enable the disease organisms to attack the human body. This First-Year Seminar will introduce students to the disease tuberculosis, to human innate and adaptive immune systems and to the molecular biology of Mycobacterium tuberculosis, an intracellular pathogen which infects humans and manipulates the human immune response to escape detection and elimination. We will even grow cultures of Mycobacterium smegmatum, M. tb’s harmless relative. In addition, millions worldwide have tuberculosis, and this disease is a case study in the measures that are being used to control the spread of an epidemic disease. Students will learn through by readings from books such as The White Plague by Rene’ and Jean Dubos, The Microbe Hunters by Paul de Kruif, The Aetiology of Tuberculosis by Robert Koch and Fever by John Fuller, videos, class interactions and discussions, and after the introductory portion of the course, by presentations of research papers about M. tuberculosis pathogenesis and treatment. Finally, we will explore recent genomic research that has yielded specific Mtb peptides that give evidence of being the basis of first effective vaccine for tuberculosis.
Animals have evolved a vast array of sensory systems that support a rich repertoire of natural behaviors. Some animals live in dark environments and use tactile, chemical, electrical and auditory sensors that allow them to operate in the absence of light. Other animals rely heavily on vision and take advantage of colors that humans cannot see. In this First-Year Seminar, we will explore extraordinary adaptations of sensory systems in animals that live on land and under water. Our focus will be on sensory systems that guide navigation and foraging behaviors in species as diverse as star-nosed moles, weakly electric fish, honeybees, and echolocating bats. As we delve into understanding the extraordinary sensory systems of selected species, we will also consider how these animals have inspired literary and visual artists. We aim to introduce students to a rich interdisciplinary experience that opens their eyes to new areas of inquiry as they take advantage of local resources, such as the National Aquarium, Baltimore Zoo, Wyman Park, Peabody School of Art, and Baltimore Museum of Art.
How we become unique is one of the deepest questions that we can ask. The answers, where they exist, inform how we think about morality, public policy, faith, health care, education, and the law. Although investigating the origins of individuality is not just an endeavor for biologists, many of this topic’s most important aspects involve fundamental questions about the development, genetics, and plasticity of the nervous system. The good news is that recent scientific findings are illuminating this question in ways that are exciting and sometimes counterintuitive. The better news is that it doesn’t just boil down to the same tiresome nature-versus-nurture debate that has been impeding progress and boring people for years. Genes are built to be modified by experience. That experience is not just the obvious stuff, like how your parents raised you, but more complicated and fascinating things like the diseases you’ve had (or those that your mother had while she was carrying you in utero), the foods you’ve eaten, the bacteria that reside in your body, the weather during your early development, and the long reach of culture and technology.So, let’s dig into the science together. Our sources will be not only books and articles but also visits by guest scientists and artists as well as engagement with films and stories that explore human individuality. It can be controversial stuff. Questions about the origins of human individuality challenge our concepts of nation, gender, and race. They are inherently political and incite strong passions. Given this fraught backdrop, we’ll do our best to play it straight and synthesize the current scientific consensus (where it exists), examine the controversies, and point out where the sidewalk of our understanding simply ends.
This First-Year Seminar explores the scientific-technological, philosophical, social, and ethical dimensions of using animals for scientific research from the early nineteenth century to present. Why did scientists use animals and how did they choose “the right animal for the job”? How did philosophers define a “model organism”? What were the political economies formed within research communities sharing research animals? How did financial and material infrastructure take shape for large-scale, long-term maintenance of genetically standardized mice or zebrafish? How did the interpretations of animals reflect the social imaginaries of researchers and our society? And how did animals “speak” back? These are questions we are going to examine through reading scholarly publications, watching documentaries, visiting laboratories, and doing mini research projects together.
"This First-Year Seminar is an introduction to the field of biological anthropology, which is broadly a mixture of social studies and biological studies that focus on human evolution and human biosocial variation. We will explore evolutionary theory and mechanisms of inheritance, the diversity of living primates, the fossil record, human evolution, and modern human biological variation. We will begin the semester by learning the basic principles of evolution and natural selection as proposed by Charles Darwin. We will then move on to consider the primate condition across species and through time. This involves examining the taxonomy of extant monkeys and apes as well as the fossil and archaeological record of our hominin ancestors that begins some 7 million years ago. This will involve excursions to local zoos and museums, as well as visits to labs right here at Hopkins. Following a survey of human biocultural evolution, we will consider how this history has influenced contemporary human biological variation.

Every day decisions often require us to weigh the costs and benefits of engaging in a particular course of action in order to obtain some expected outcome. Unfortunately, we often lack the information necessary to obtain our desired goal with complete certainty. Economists have long been interested in understanding human decision-making under these circumstances. In parallel, neuroscientists have made great strides at describing the underlying neural basis of simple decision-making. However, despite much progress in both fields, our understanding of how the brain makes decisions is incomplete. In order to strengthen and further research in both fields, the interdisciplinary field of Neuroeconomics arose. This course will survey the field of Neuroeconomics focusing on theoretical concepts developed by economists and the role these theories are playing in guiding current experimental neuroscience.
