The importance of microbiology in complex issues, such as the impact of the microbiome in human health or as alternative energy sources, is being appreciated more and more each day. This upper level laboratory course provides students with a robust technical skill set while also giving them an opportunity to participate in an authentic research project that may lead to novel discoveries. Students will generate research questions, formulate hypotheses, design experiments, analyze data, and present their research findings to the class. In each project, students will use the cutting edge approach of metagenomics to evaluate the microbial diversity of their environment via Next Generation Sequencing. Students will also examine the function of microbial species within their communities. Potential projects include the isolation of novel antibiotic producers and the antibiotic they produce, designing and optimizing microbial fuel cells that can be used to generate electricity, or isolating antibiotic resistant bacteria and attempting novel approaches to inhibit or prevent their growth.

This course is a lab/lecture/seminar hybrid that will meet once per week for three hours. Each session will consist of mini-lecture/lab, paper discussions/lab, or solely lab efforts. All reading assignments will be available on Canvas (no textbook fees). We will exam various aspects of photosynthesis, water relations and nutrient acquisition in the context of the evolutionary progression of higher plants. With each subject, we will consider, measure, and in some cases model whole-plant physiology while examining sub-cellular-level controls and ecosystem-to-global-level consequences. This course is designed to give molecular biologists through earth-system scientists the tools to measure and understand whole-plant physiological responses to molecular manipulation and environmental variability. All students will learn to appreciate the context of their work on both micro and macro scales.

Survey of the physical, chemical and biological properties of freshwater ecosystems, both riverine and lentic, natural and polluted.

Theories and mechanisms of evolution, with emphasis on the genetic basis of evolutionary change.

This course is designed for students in graduate level degree programs with an interest in developing a strong understanding of core concepts in genetics and omics technologies. It is assumed that students either have familiarity with undergraduate level biology topics, or can quickly catch up to keep pace with the course. We will focus on genetics, genomics, and bioinformatics topics ranging from transcriptomics to transgenic organisms to epigenetics. This fast-paced course will cover both foundational principles, as well as modern applications and developments, offering hands-on active learning opportunities where possible. Students will be expected to engage deeply with the material, and will have the opportunity to develop scientific skills in critical thinking, reading, and communication, culminating in a final group presentation at the end of the semester. Upon completion of the course, students should feel empowered to enroll in any advanced genetics/genomics-based biology course at Penn.

This class explores the evolutionary battles that play out between genes within and across genomes. Pathogens evolve their molecular arsenal to manipulate host cells and enhance their own replication. The host genome fights back with molecular defense mechanisms that evade or suppress the invading bacterial and viral pathogens. Such “molecular arms races” also play out between host genomes and genomic parasites called selfish genetic elements. These selfish elements, like transposons, spore killers, and meiotic drivers, similarly evolve to replicate in their host genomes and the host genome evolves to block proliferation and mitigate the collateral damage. Finally, conflicts over access to mates drives genetic innovations. We will learn about these molecular arms races using the primary literature. During our course meetings, we will discuss assigned articles and engage in small groups around multiple writing assignments. Presentation preparation and writing are two skills that we’ll develop over the semester.

This course will be a focused study of genomes, genomic techniques, and how these approaches are and will be used in diagnosing and treating human disease. Topics will include genome sequencing, analysis of sequences and microarrays, and new techniques including high-throughput sequencing and reverse genetic analysis with a focus on genome-wide mutant collections.

This course will survey the discipline of molecular genetics. Two broad areas will be considered 1) Molecular Biology: DNA replication, transcription, translation, regulation of gene expression in both prokaryotic and eukaryotic systems, and genomics and 2) Genetics: basic Mendelian & molecular genetics.
