Rhesa discovered her scientific interest many years ago in a high school chemistry class. Her inspirational teacher, Mr. Best—the stereotypical science geek with large bug-eye glasses—taught Rhesa many scientific lessons, but perhaps the greatest was that science is not just for nerdy boys (as her flawed logic thought), it is for anyone.
Currently, a Ph.D. student in the Department of Chemistry and Biochemistry at Utah State University, Rhesa can be found at the laboratory bench doing research focused on understanding and harnessing the amazing abilities of microorganisms. Specifically, she studies the microbial transformation of nitrogen (N2) to ammonia (NH3). This process is a critical part of nature as the majority organisms cannot utilize N2 directly, but need it in a form like NH3 for growth and reproduction. The few microbes that facilitate this conversion provide valuable insight into one of the most biologically challenging reactions and may serve as a catalyst for developing systems for sustainable ammonia production on Mars.
In additional to research, Rhesa also serves as a science reporter for Utah Public Radio and plans to pursue a career in science education and/or communication. Her excitement for not only doing science, but communicating it just might stem from growing up doing musical theater, which she loves. She also enjoys experiencing other cultures, and hot-potting is always on her list of things to do (and yes, it’s partly to see the beautiful microbial mats)!

David Merkley is an undergraduate student at Utah State University in his Junior year. He is studying computational mathematics and pre-med. David is from Centerville, Utah and has 3 brothers. When he is not studying for school, you can find David either wakeboarding or skiing the slopes.
David has always wanted to help out other people, which is one reason that led to him towards becoming a physician. David has always said that he wanted to feel like he was helping to make a difference in the world. Another reason is that the human body fascinated him. Wondering how medications interacted with the cells, enzymes, and other elements of the body was something that was always a question for him. He wanted to understand more about the human body and how all of the different parts worked in unison.
One way that you could describe David would be, welcoming and hilarious. He is genuinely concerned with others surrounding him and wishes the best for them. He can always make someone smile, even when they're having a rough day. Individuals seem to feel at ease around him.

Tom is a Visiting Scholar from the Netherlands completing the research for his master thesis in the Peidong Yang Group. His work is focused on the microbial synthesis of ammonia from dinitrogen gas. Ammonia is essential for a successful manned mission to Mars. However, it is not feasible to achieve the current production method, the Haber-Bosch process, on Mars due to limited resources. Therefore, the search for an alternative way to produce ammonia is paramount to the success of this mission. The reduction of dinitrogen gas with a solar-driven potential and bacteria as catalysts is a very promising way of achieving this.
