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.

The goal of this course is to gain an understanding of the chemical principles that govern biological systems. We will look at the structure and function of biomolecules (proteins, carbohydrates, nucleic acids, and lipids), with an emphasis on interactions between them, enzyme kinetics, and metabolic pathways. Key topics will include protein folding and function, enzyme mechanisms, bioenergetics, and the regulation of key metabolic cycles. In addition to lecture we will spend time examining case studies and selected articles from primary literature, and engaging in group discussions.

Prerequisites: one year of biology; a course in physics is highly recommended. This is an advanced course intended for majors providing an in depth survey of the cellular and molecular aspects of nerve cell function.

Transcriptome analysis, or the analysis of all expressed RNA sequences in a cell, has long been a major part of molecular biology and genetics. The modern technique of RNA-Seq has now been established as the approach for transcriptome studies and RNA-Seq analyses are ubiquitous in all areas of Biology. In this course we will cover the major technical and analytical aspects of RNA-Seq with an emphasis on the application by students to real datasets. We will cover both the original ‘Bulk RNA-Seq’ approach, where the total transcriptome of many cells are combined, and the more recent ‘single-cell RNA-Seq’ (scRNA-Seq) technology where transcriptomes of individual cells are analyzed separately. Students will learn to read and interpret journal articles that utilize RNA-Seq datasets, both bulk and single-cell, and to perform and present RNA-Seq data using publicly available datasets.

This laboratory course will explore fundamental techniques that are frequently utilized in modern molecular biology laboratories. A combination of experiments will provide broad exposure to several important techniques in molecular biology. Experiments include current approaches to site-directed mutagenesis, cloning by PCR, and mutation analysis. Students will pursue multiple experimental projects and will gain experience with scientific thinking and scientific communication. SPS and TC students may register for this course, but they must first obtain the written permission of the instructor, by filling out a paper Registration Adjustment Form (Add/Drop form).

Prerequisites: UN2005/UN2401 and UN2006/UN2402, or the equivalent at a different institution, and Contemporary Biology Laboratory (UN2501).

This course serves as a continuation of BIOL2500 R for Scientists. The course will meet weekly. Students will explore a range of methods and resources used by contemporary computational biologists. These include advanced statistical modeling approaches, manipulating genomic and spatial data, and working in R outside of the RStudio environment (including git, bash, Shiny and high-performance computing). Students will have opportunities to explore diverse biological and statistical R packages in the context of homework assignments, and will analyze a dataset of their own choosing for a semester project.

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.

Introduction to the use of molecular techniques to answer questions about subcellular biological phenomena. Techniques include isolation of genomic and plasmid DNAs, restriction enzyme analysis, DNA and protein electrophoresis, bacterial transformation, and plasmid subcloning.

This course explores the components, systems, and regulatory mechanisms involved in eukaryotic cellular function. Topics include: signal transduction, translational and protein quality control, organellar and cytoskeletal dynamics, and some coordinated responses such as proliferation and programmed cell death. Throughout the course we will see how general cell biology can be specialized to achieve specific cellular functions through regulation of the basic machinery. We will also explore the cellular and molecular bases for a variety of human pathologies, with an emphasis on cancer. In addition to lecture, we will spend some time discussing the material, including selected articles from the primary literature, and learning through group presentations.

Introduction to cell biological techniques used to investigate structural, molecular, and physiological aspects of eukaryotic cells and their organization into tissues. Techniques include light and electron microscopy, cell culture, isolation of cellular organelles, protein electrophoresis, and Western Blot analysis.

To maximize their survival animals must regulate their behavior in response to external environmental cues and their own internal state. A fundamental goal of neuroscience is to understand how neural circuits in the brain function to influence behavior. The aim of this course is to highlight the neural basis of neuropeptide regulation of innate behaviors that are critical for survival and discuss modern approaches to study the neuronal control of classically studied aspects of behavior. We will explore motor control (escape responses), sensory systems (vision, taste, and olfaction), and survival behaviors (feeding, drinking, mating, and aggression). Focus will be on recent and current research, the diversity of approaches for studying it, and how this knowledge can be applied to solve scientific questions. Students will read primary scientific literature and a significant portion of the course will be presentation and discussion-based.

Prerequisites: BIOL BC1500, BIOL BC1501, BIOL BC1502, BIOL BC1503 or the equivalent, and BIOL BC2100. Survey of the diversity, cellular organization, physiology, and genetics of the major microbial groups. Also includes aspects of applied microbiology and biotechnology, the function of microorganisms in the environment, and the role of microbes in human diseases.

This course will explore developing topics in mammalian reproductive biology. Using textbooks and 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:  BIOL BC1502 + BIOL BC1503, and either BIOL BC1500 + BIOL BC1501 or NSBV BC1001 or permission from the instructor.

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.

Antimicrobial resistant bacterial infections were estimated to account for 1.27 million deaths worldwide in 2019. The goal of the seminar is to provide an in-depth analysis of this ongoing threat. Discussions will include the molecular mechanisms, epidemiology of transmission and the consequences of antimicrobial resistant infections. It will also cover current efforts to reduce the spread and emergence of these difficult to treat pathogens, both in the community and the healthcare setting.

This course is an advanced seminar that will review current knowledge about the computation carried out by microcircuits present in the mammalian CNS. This year the seminar will focus on dendritic integration and in the function of dendritic spines. The class will run as a seminar discussion, where it is assumed that every student will have studied the reading material ahead of time and will be knowledgeable enough to explain it. Students should expect a minimum of 9 hours of work / week (classroom + work at home combined).

Prerequisites: genetics or molecular biology. The course covers techniques currently used to explore and manipulate gene function and their applications in medicine and the environment. Part I covers key laboratory manipulations, including DNA cloning, gene characterization, association of genes with disease, and methods for studying gene regulation and activities of gene products. Part II also covers commercial applications, and includes animal cell culture, production of recombinant proteins, novel diagnostics, high throughput screening, and environmental biosensors.

Systems biology approaches are rapidly transforming the technological and conceptual foundations of research across diverse areas of biomedicine. In this course we will discuss the fundamental developments in systems biology with a focus on two important dimensions: (1) the unique conceptual frameworks that have emerged to study systems-level phenomena and (2) how these approaches are revealing fundamentally new principles that govern the organization and behavior of cellular systems. Although there will be much discussion of technologies and computational approaches, the course will emphasize the conceptual contributions of the field and the big questions that lie ahead. Lectures and discussions of primary literature will enable students to scrutinize research in the field and to internalize systems biology thinking in their own research. To make this a concrete endeavor, the students will develop mini-NIH-style grant proposals that aims to study a fundamental problem/question using systems biology approaches. The students will then convene an in-class NIH-style review panel that will assess the strengths and weaknesses of these proposals. In addition, the students will have the opportunity to defend their proposals in a live presentation to the class. The course is open to graduate students in Biological Sciences. Advanced undergraduates in biological sciences, and other graduate students with background in biology from other disciplines, including physics, chemistry, computer science, and engineering may also attend after consulting with the instructor.

This course provides a rigorous introduction to the theory underlying widely used biophysical methods, which will be illustrated by practical applications to contemporary biomedical research problems. The course has two equally important goals. The first goal is to explain the fundamental approaches used by physical chemists to understand  the behavior of molecules and to develop related analytical tools. The second goal is to prepare students to apply these methods themselves to their own molecular biology research projects. The course will be divided into seven modules: (i) solution thermodynamics with an emphasis on application to analysis of protein structure, folding, and binding interactions; (ii) hydrodynamic methods; (iii) statistical analysis of experimental data; (iv) molecular dynamics calculations; (v) optical spectroscopy with an emphasis on fluorescence; (vi) nuclear magnetic resonance spectroscopy; and (vii) light-scattering and diffraction methods including an overview of cryogenic electron microscopy reconstruction methods. In each module, the underlying physical theories and models will be presented and used to derive the mathematical equations applied to the analysis of experimental data.  Weekly recitations will emphasize the analysis of real experimental data and understanding the applications of biophysical experimentation in published research papers.  The problem sets emphasize use of PyMOL for analysis of macromolecular structures and use of standard curve-fitting software for analysis of protein binding data; detailed tutorials on the related methods are provided in the recitation sections.  The first three modules will be covered in Biophysical Chemistry I during the fall term, while the final three  will be covered in Biophysical Chemistry II during the spring term, and treatment of molecular dynamics calculations will be divided between the two terms.

In this course, we will explore the basic biochemistry of living systems and how this knowledge can be harnessed to create new medicines. We will learn how living systems convert environmental resources into energy through metabolism, and how they use this energy and these materials to build the molecules required for the diverse functions of life. We will discuss the applications of this biochemical knowledge to mechanisms of disease and to drug discovery. We will look at examples of drug discovery related to neurodegeneration, cancer, and the SARS-CoV-2 COVID19 pandemic. This course satisfies the requirement of most medical schools for introductory biochemistry, and is suitable for advanced undergraduates, and beginning graduate students. This course is equivalent to and replaces the prior course named UN3501, and is equivalent to the course offered in the summer.

Prerequisites: one year of biology; a course in physics is highly recommended. This is an advanced course intended for majors providing an in depth survey of the cellular and molecular aspects of nerve cell function. Topics include: the cell biology and biochemistry of neurons, ionic and molecular basis of electrical signals, synaptic transmission and its modulation, function of sensory receptors. Although not required, it is intended to be followed by Neurobiology II (see below).

Prerequisites: at least 4 college-level biology or biotechnology courses. This course will introduce students to the interrelated fields of patent law, regulatory law, and contract law that are vital to the biotech and biopharmaceutical sectors. The course will present core concepts in a way that permits students to use them throughout their corporate, academic, and government careers.
