Bacterial Genomics

Unlock the secrets of microbial genomes to understand the evolution of stress resistance.

About the Program

Participants in the Summer Science Program in Bacterial Genomics study the evolution of stress resistance in a non-pathogenic bacterium. By introducing ever increasing amounts of stressors, the population is forced to evolve or perish – and we can study that evolution by analyzing their DNA and how it changed from the ancestral strain. Through this process, participants gain hands-on experience with the microbiology, molecular biology, genetics, genomics, and bioinformatics that they’ll need to go from the output’s seemingly random ATGCs to annotated genomes and eventually to identify putative mutations that gave rise to that bacteria’s stressor resistance.

The Bacterial Genomics program provides participants with the skills to conduct lab experiments and research that can tackle complex, real-world life science problems from a microscopic to a macroscopic level. Participants will also be mentored by genomic scientists and have the chance to meet with guest lecturers and speakers who are excited to share years of genomic research.

Is the Summer Science Program in Bacterial Genomics Right for You?

Applications are open each winter to current high school juniors who have completed or are in the process of completing any level of high school biology and algebra II by June for credit and a grade. We do NOT require AP or advanced-level classes. Self-study does not qualify.

Applicants must be at least 15 years old but not yet 19 during program operation. Current freshmen, sophomores, and seniors are not eligible.

2025 Research Project: Antibiotic Resistance and Directed Evolution

When any living thing reproduces, its DNA is copied – a process subject to random copying errors. Those copying errors are called “mutations,”” and they can be detrimental, neutral, or beneficial – and interestingly, a beneficial mutation under certain conditions might be detrimental in another! For instance, mutations that frequently occur to combat certain antibiotics happen in the protein machinery of the cell. These cells can survive the antibiotic but might grow overall slower than the ancestral strain. While antibiotics are a common stressor studied in the lab (and rightly so, as antibiotic resistance in bacteria is serious public health concern across the globe) these stressors can include innumerable things such as UV radiation, heavy metals, oxidative stress, and even too much or too little salt.
 
In the “Cell Stress and Directed Evolution” research project, you will study and stimulate the growth of a non-pathogenic bacteria while exposing it to a specific stressor to apply evolutionary pressure and select for stress-resistance mutations. This process is called “directed evolution” and is a key technique used by researchers to study both evolution and genetics. The identified mutation will help us better understand stressor resistance and gain insight into combatting public health problems worldwide.

A Preview of the Experience

You will work with a team of three to maintain the constant growth of a non-pathogenic bacteria under ever-increasing stress (and therefore selective pressure) using a custom chemostat, a device used to cultivate microorganisms. The chemostat includes components for mixing and aeration of the growth media, optical growth rate monitoring, and feedback control of stressor delivery to the culture. Teams will then sequence their evolved strains, re-create the full genome, and map any mutations that arose as a result of the incomplete growth suppression.

Summer Science Program faculty will teach the underlying science and hands-on techniques that teams will use in their research, including:
