Course overview: 

Once a small subfield of biology, computational biology has evolved into a massive field of its own, with computational methods fast becoming a vital toolkit leveraged by biologists across the discipline. As the size and complexity of biological datasets grows, computational methods allow scientists to make sense of these data, scaling quantitative methods to extract meaningful insights that help us better understand ourselves and the living world around us. In this course, we will learn the basics of computer programming in R, a powerful programming language with wide use in the biological sciences. Topics will include a basic introduction to R and the RStudio environment, data types and control structures, reading and writing files in R, data processing and visualization, manipulating common biological datasets; and statistical testing and modeling in R.

Prerequisites: 1 year of Introductory Biology, 1 year General Chemistry, and 1st semester Organic Chemistry.  Biochemistry is the study of the chemical processes within organisms that give rise to the immense complexity of life. This complexity emerges from a highly regulated and coordinated flow of chemical energy from one biomolecule to another. This course serves to familiarize students with the spectrum of biomolecules (carbohydrates, lipids, amino acids, nucleic acids, etc.) as well as the fundamental chemical processes (glycolysis, citric acid cycle, fatty acid metabolism, etc.) that allow life to happen. The course will end with a discussion of diseases that have biochemical etiologies. In particular, this course will employ active learning techniques and critical thinking problem-solving to engage students in answering the question: how is the complexity of life possible? NOTE: While only the 1st semester of Organic Chemistry is listed as a pre-requisite, it is highly recommended that you take all of Organic Chemistry beforehand.

Selected topics in molecular genetics and gene regulation, with a focus on examples from human evolution, physiology, and disease. The course will be organized into four modules with combined lecture and journal club-style discussion. Module topics include molecular regulation of transcription, epigenetic regulation of the genome, gene regulatory networks, and genome architecture and evolution. We will draw from examples in the current literature and explore current experimental approaches in molecular genetics of humans and model organisms. 

Laboratory course in which students conduct original research projects in molecular genetics. Students will participate in experimental design, conduct data analysis, and work with key techniques for studying gene structure, expression, and function including nucleic acid extraction and synthesis, cloning, bioinformatics analysis, PCR, and qPCR. Students will present their results orally and in writing. Enrollment in both semesters (BIOL BC3305 and BIOL BC3306) of this full-year course is required, and fulfills two upper-level lab courses for the Barnard Biology major. Must be taken in sequence, beginning in the fall. 

Prerequisites: BIOL BC1500, BIOL BC1501, BIOL BC1502, BIOL BC1503 or the equivalent, and BIOL BC2100.

This is an advanced seminar course focusing on primary literature studying viruses and their impact on public health. Selected topics will emphasize evolution, transmission, surveillance, and treatment. The intellectual framework will progress from the cellular and molecular levels to the organismal and ecological. Host-pathogen interactions between viruses and humans will be a particular focus. The course is organized around presentation and critique of both current research as well as landmark discoveries in the field. Discussions will also integrate the interplay of laboratory science with ethics and policy.

This lab course will explore the foundational methods of vertebrate embryology. Using both classical and modern experimental approaches, we will identify and manipulate developmental processes such as gastrulation, neurulation, and organogenesis. Students will investigate molecular regulation of patterning and the importance of tissue-tissue interactions during early development. Utilizing modern genetic tools and imaging techiniques, such as digital microscopy, students will have the opportunity to visualize embyrogenesis in real-time. 

Prerequisite: Two terms of introductory biology (BIOL BC1500,BC1502 or equivalent) AND one term of Genetics (BIOL BC2100 or equivalent) AND at least one upper level lab course at the cell and molecular level. OR permission from the instructor.

This course will explore developing topics in reproductive biology, with a focus on mammalian reproduction. Using primary literature sources we will explore the molecular and physiological nature of reproduction, including fertilization, assisted reproductive technologies, and physiological changes to the reproductive system during and after birth. These topics will be further discussed in the context of medicine and society, with a particular focus on healthcare disparities in local communities. 

Prerequisites: Pre- (or co-) requisite is a physiology lecture class (e.g. BIOL BC3360). Enrollment limited to 16. Provides a hands-on introduction to the different physiological systems in vertebrates and invertebrates. Emphasizes the operation of a variety of physiological monitoring devices and the collection and analysis of physiological data.

Vertebrates have been around for millions of years. In that time, they have evolved morphological attributes to live in the sea, on land, and in the air; hunt or scavenge food; escape from predation; and more. Yet despite the vast differences that have evolved, vertebrates (including humans) share many common traits. In this course, we will explore the evolution of the vertebrate body plan, focusing specifically on the evolution of form and function in many body systems. We will examine the evolution of homologous structures and identify how vertebrates have evolved a wide array of adaptations within the constraints of evolution. Though anatomy courses necessitate memorization of some key structures, we will focus more on the function of those structure, the broad principles of evolution, and the research techniques used in the related field of functional morphology rather than memorizing large lists of terms.

RNA has recently taken center stage with the discovery that RNA molecules sculpt the landscape and information contained within our genomes. Furthermore, some ancient RNA molecules combine the roles of both genotype and phenotype into a single molecule. These multi-tasking RNAs offering a possible solution to the paradox of which came first: DNA or proteins. This seminar explores the link between modern RNA, metabolism, and insights into a prebiotic RNA world that existed some 3.8 billion years ago. Topics include the origin of life, replication, and the origin of the genetic code; conventional, new, and bizarre forms of RNA processing; structure, function and evolution of key RNA molecules, including the ribosome, and RNA therapeutics including vaccines. The format will be weekly seminar discussions with presentations. Readings will be taken from the primary literature, emphasizing seminal and recent literature. Requirements will be student presentations, class participation, and a final paper.

The basic thesis of the course is that all viruses adopt a common strategy. The strategy is simple:

1. Viral genomes are contained in metastable particles.

2. Genomes encode gene products that promote an infectious cycle (mechanisms for genomes to enter cells, replicate, and exit in particles).

3. Infection patterns range from benign to lethal; infections can overcome or co-exist with host defenses.

Despite the apparent simplicity, the tactics evolved by particular virus families to survive and prosper are remarkable. This rich set of solutions to common problems in host/parasite interactions provides significant insight and powerful research tools. Virology has enabled a more detailed understanding of the structure and function of molecules, cells and organisms and has provided fundamental understanding of disease and virus evolution.

The course will emphasize the common reactions that must be completed by all viruses for successful reproduction within a host cell and survival and spread within a host population. The molecular basis of alternative reproductive cycles, the interactions of viruses with host organisms, and how these lead to disease are presented with examples drawn from a set of representative animal and human viruses, although selected bacterial viruses will be discussed.

The course covers a general introduction to the theory and experimental techniques of structural biology (protein expression and purification, protein crystallography, cryo-electron microscopy, nuclear magnetic resonance) and then how to use the structural information to understand biochemical and biological processes. The first part of the course will cover the general introduction to structural biology. The second part of the course will involve discussions and explorations of various structures, led by the instructor but with substantial participation from the students, to understand the molecular mechanisms of selected biochemical and biological processes. In the final part of the course, each student will select and lead discussions on a primary structural biology paper. The overall goal of the course is to increase the understanding of how protein structures are determined, what protein structures look like, and how to use the structures to understand biology.

Prerequisites: BIOL UN2005 and BIOL UN2006 or the equivalent. General genetics course focused on basic principles of transmission genetics and the application of genetic approaches to the study of biological function.
