This physics course covers the physical principles of major in vivo bio-imaging modalities.

This course will focus on magnetic resonance imaging, also known as an MRI. In the first part of the course, the dynamic of spins in a magnetic field is described, leading to the essential notions of magnetic resonance (MR), excitation and relaxation. We will also discuss the basic mechanisms of image reconstruction, MR spectroscopy and functional MRI.

You will learn how existing physical principles transcend into bio-imaging and establish an important link into life sciences, illustrating the contributions physics can make to life sciences. Practical examples will be shown to illustrate the respective imaging modality, its use, premise and limitations, and biological safety will be touched upon.

During this course, you will develop a good understanding of the mechanisms leading to tissue contrast of the bio-imaging modalities covered in this course, including the inner workings of the scanner and how they define the range of possible biomedical applications. You will be able to judge which imaging modality is adequate for specific life science needs and to understand the limits and promises of each modality.

This physics course covers the physical principles of major in vivo bio-imaging modalities and the different imaging techniques.

Marketing excellence is a prerequisite for success in any business, from startups to the world’s most established enterprises, yet the art and science of marketing is constantly evolving. Arm yourself with the essential principles and practices of marketing in the digital economy by making this course, taught by Internet consumer shopping expert and Wharton professor David Bell, an indispensable part of your knowledge base.

In this business and management course, you will gain an understanding of how the digital economy works and develop the critical insights necessary to succeed in e-commerce and digital and social media marketing.

The fixed and mobile Internet and related technologies exert a profound influence on how business and social institutions evolve, how they are challenged—and sometimes, even displaced. Companies that were non-existent a few short years ago, including Facebook, LinkedIn, and Uber, have dramatically changed how we interact, communicate and get from point A to B. Even Amazon and Google are relatively “young” by any measure. If you’re an entrepreneur, investor, manager, or student, you need thoughtful approaches to navigate and win in this new environment.

This course is organized around four broad themes and we will use relevant theory and analysis, as well as numerous practical examples to develop our key learning points.

The themes are:

• Behavioral foundations for understanding and navigating the new online-offline landscape
• New forms of interaction, including formation of networks and reputation building
• Tools and principles of digital marketing action including online advertising on fixed and mobile devices
• New media platforms and emergence of “organic” celebrities and communities

This course is beneficial to marketing professionals, analysts, entrepreneurs, small business owners, investors, and consumers This course evolved from the University of Pennsylvania’s Wharton School’s very first course on digital marketing and e-commerce.

This course is part of Wharton's Digital Marketing Professional Certificate. For more information, see here.

When you're sick, you may wonder, "Why me?" But the real question should be, "Why am I not sick all the time?" You might even ask, "Why does my body respond with a fever, and is it really a good idea to lower it?" This course explores immunology, how the body defends itself from constant assault by parasites and pathogens. This course will present the fundamentals of both innate and adaptive immunity, emphasizing functional interactions among cells and organs. We will cover signaling, pathogen recognition and the division of labor among myeloid, lymphoid and supporting cells. The subject matter will also supply health professionals and biomedical researchers with the basic vocabulary and concepts necessary to understand both clinical press releases and primary literature. The course materials also provide support to other immunology instructors by presenting difficult concepts in creative ways using analogies and models.
