The popular press has called the twentieth century "The Century of the Gene." During this time, genetics came forward as a central discipline in biology, first with the rediscovery of the work of Gregor Mendel at the turn of the century, later with the elucidation of the structure of DNA by Jim Watson and Francis Crick, and more recently with the development of recombinant DNA technologies by Paul Berg and Herb Boyer. These scientific events revolutionized the way we thought about biological problems. Mendel's contributions led scientists to probe the genetic basis of inheritance while Watson and Crick helped to define the molecular nature of this inheritance. Berg and Boyer developed the tools that allowed scientists to manipulate these molecules of inheritance to more deeply understand their functions. Each of these events has had far-reaching consequences because of the explosion of scientific inquiry it both allowed and inspired.

Currently, scientists of the twenty-first century are poised at the brink of another genetic revolution, this time triggered by the genome projects of organisms from microbes to humans. With the availability of this data, it has become obvious that current computational tools alone are inadequate to fully mine this immense data set. Although the power of current genomic strategies is tremendous, they are not sufficient to determine gene function. Consequently, scientists are seeking to ascertain gene function using two main approaches. First, there is a great effort underway to create new technologies and computational tools to allow for large scale molecular analyses of complex systems. Secondly, these strategies are utilized alongside methods that take advantage of the powerful role of model organisms in helping to determine gene function, an important focus of the Genetics and Genomics department. This global perspective on the intricate networks that govern the machinery of life is causing a shift in the traditional paradigm of identifying the impact of individual genes on any given process. Instead, the revised concept that no gene acts in isolation is more easily explored with these new genomic and bioinformatics tools.

The aim of our Department in establishing a graduate coursework in Genetics and Genomics is to teach our students to apply the approaches of classical genetics and modern genomics to investigations of the heritable basis of numerous biological traits, the relationships among genes, the regulation of their expression, and the elaborate mechanisms involved in supporting complex biological processes. We want our students to be adept at utilizing traditional hypothesis-driven methods as well as discovery-oriented experimental design styles to explore these problems. The combination of these two tactics will allow our students to systematically and broadly make important contributions to many disciplines of biology. Moreover, it is our goal that our students will also be trained to function as active members of the scientific community who can clearly communicate ideas, critically evaluate biomedical research, and mentor others in scientific scholarship.

Towards this end, we are proud to announce the first graduate course offering from the Department of Genetics and Genomics. "Principles of Genetics and Genomics" will focus on the use of genetic methods in model organisms for understanding the heritable basis of numerous biological traits, the relationships among genes, the regulation of their expression, and the elaborate network of cellular machinery involved in supporting complex biological processes. This course will focus on the ability to use genetic systems to probe these problems, and therefore will heavily explore the experimental aspects of these investigations. In addition, we will discuss the impact of the genome sequences on the practice of modern science. In this regard, the course will be aimed towards first year PhD students in the biological sciences, but the course will be open to anyone wishing to study genetic approaches to biological research. In addition, we will use a case study approach to investigate the rich variety of scientific insights gained through genetic studies. Further details on this course and our other exciting courses for graduate and medical students can be found on the course website.

Furthermore, we have developed a Graduate Program in Genetics and Genomics designed to bring these same approaches to an entire coordinated curriculum. Our Graduate Program aims to bridge the disciplines of classic experimental biosciences with modern computational and genomic approaches. The program will consist of laboratory rotations, advanced coursework, and journal clubs in the first year. Subsequently, graduate students will focus on their thesis research, qualifying exams, and a teaching requirement. Additional information on our graduate program can be found on the graduate program website.
