Biological Sciences

Exploration of the major discoveries and ideas that have revolutionized the way we view organisms and understand life. This is an introductory survey course that explores basic concepts of molecular and cellular biology, genetics and evolution. Students will focus on biological concepts, biotechnology and bioethics, which inundate contemporary society.

This course uses a seminar discussion format to examine the relationship between science and society from numerous perspectives, with examples from many fields of science, mostly biology and medicine, including the Covid-19 pandemic. We welcome undergraduates from all classes who are concentrating in any field: the natural and social sciences, humanities, or the arts. There are no prerequisites, other than an interest in how the scientific enterprise works and interacts with other components of our society.  

The course addresses a wide array of topics, such as: why do people choose a scientific career? why do governments and other funders support scientific work? how does science fail? why is there widespread skepticism about science? how is it represented in the arts? how are results disseminated, evaluated, and legally protected? Assignments-- mainly short articles (from newspapers and journals) and book chapters, but also a few films and novels --will be provided for each class, and every student will undertake a term project of their own choosing, with oral and written presentations, after consultations with the instructor.

Course suitable for fulfillment of premedical requirements. Detailed introduction to biological phenomena above the cellular level; development, anatomy, and physiology of plants and animals; physiological, population, behavioral, and community ecology; evolutionary theory; analysis of micro-evolutionary events; and systematics.

This class focuses on how we gather reliable scientific evidence about human biology and public health. The aim is to help students better interpret and evaluate the scientific evidence that they will encounter throughout their lifetime, in primary papers but also as presented in news, advertisement, and politics. To these ends, students will be introduced to basic definitions and concepts in statistics and epidemiology, including point estimates and measures of uncertainty, p-values, error rates, association and causation, different study designs, and selection bias. Readings will draw from a textbook as well as the primary literature. The second half of the course will turn to dissecting the representation and misrepresentation of scientific evidence presented in different venues. It will draw primarily from the textbook “Calling Bullshit” and include discussions of timely examples from the news.

Prerequisites: 1st semester 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. 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 1 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. 

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.

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.

Students will read and discuss classical as well as contemporary research papers on the molecular and cellular mechanisms of membrane excitability, synaptic transmission and sensory transduction, and the pathogenic mechanisms and therapeutics of certain neurological diseases related to these processes. Focus will be on intellectual creativity, conceptual breakthroughs, and technical advances. A key goal of the course is to help students become a critical reader and thinker. Graduate students in all disciplines are welcome. Advanced undergraduate students can enroll with instructor’s permission.

For PhD students in the Biological Sciences Program, this is a tier 3 course.

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.

We will aim for practical understanding of the fundamentals of Python programming, image visualization & rendering tools and common image processing tasks, including image segmentation, measurements of features and registration.

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.

In this course, we will use mixed reality to explore the basic 3D aspects of biochemistry of living systems and how this knowledge can be harnessed to create new medicines. Students may register for this course alongside of GU4501 or independent of GU4501. Professor Stockwell will meet each week with a group of 4 students to discuss protein structures using Oculus Quest Pro Mixed Reality headsets in the XR app Nanome. Students will rotate through in person meetings but can join all weekly sessions using a virtual live stream. We will examine 3D spatial concepts relevant to biochemistry, where you will be able to examine molecular structures in an immersive format in real time with other students and with the instructor.

Prerequisites: two semesters of a rigorous, molecularly-oriented introductory biology course (such as UNC2005 and UN2006), or the instructor's permission. This course will cover the basic concepts underlying the mechanisms of innate and adaptive immunity, as well as key experimental methods currently used in the field. To keep it real, the course will include clinical correlates in such areas as infectious diseases, autoimmune diseases, cancer, and transplantation. Taking this course won't turn you into an immunologist, but it may make you want to become one, as was the case for several students last year. After taking the course, you should be able to read the literature intelligently in this rapidly advancing field.

The course brings together population genetics theory, empirical studies and genetic models of disease to provide an integrated perspective on the evolutionary forces that shape human variation and in particular disease risk. Our goals are to provide you with a basic toolbox with which to approach human variation data and in parallel, to expose you to cutting-edge research and to the forefront of knowledge in human population genetics. To this end, the course includes in-depth discussions of classic papers in these fields coupled with recent findings employing new technologies and approaches.

To organize the material, we rely heavily on population genetic models. We start with consideration of single sites, covering neutral models, forward and backwards in time; models of selection; mutation-selection balance and the nearly neutral theory. We then turn to linkage and linkage disequilibrium; population structure; linked selection and tests for positive selection. Finally, we provide a brief introduction to quantitative genetics and complex trait mapping from a population genetics perspective.

The format consists in alternating lectures and discussions of primary research papers. On most weeks, there will also be a section, led by the TA (which are compulsory, unless otherwise noted). Grades will be based on class participation (20%), five homework assignments (50%) and a final class presentation (30%). Students can work together on reading the papers for class discussion and presentation, but must work on their homework assignments alone.

Reading will consist of approximately one textbook chapter and two primary research papers per week. Papers will be provided as pdfs on the class website. Textbook reading for the course will be drawn primarily from “Population Genetics, A Concise Guide” by John Gillespie 2nd edition; the specific chapters will be provided as pdfs. Additional books that provide background for a number of topics in the class are: “Human Evolutionary Genetics” (2nd edition) by Jobling, Hurles, and Tyler-Smith, “Coalescent Theory” by Wakeley [harder] and “Elements of Evolutionary Genetics” by Charlesworth and Charlesworth [harder].

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. SCE 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). The form can be downloaded at the URL below, but must be signed by the instructor and returned to the office of the registrar. http://registrar.columbia.edu/sites/default/files/content/reg-adjustment.pdf
