Zachary Clayton

I was born and raised near Los Angeles, California.  For undergraduate I attended Arizona State University and graduated with a B.S. in biochemistry. I have been a member of the MOD Lab since 2022 and began pursing a PhD in 2021.  My research interests are the geochemical and microbial processes in volcanic systems. Outside of lab I have a passion for cooking, golf, and sports in general. 

Eliana Benites

Eliana Benites is a volunteer for the School of Earth and Space Exploration. Currently, her work focuses on research that combines science and engineering together. With an undergraduate degree in Earth and Space Exploration (Astrobiology and Biogeosciences), she’s passionate about pursuing higher education to further understand the ways in which life thrives in extreme environments. Outside of research, she loves traveling abroad, reading, hiking across Arizona, creating music, and painting her imagination. 

Christian Swonger

Hi my name is Christian! I am a senior at Arizona State University majoring in Molecular Biosciences and Biotechnology. My academic interests revolve around microbes, biotechnology, and space exploration. Outside of academia I enjoy experimenting with coffee, bouldering, traveling, and reading comics. As a final year student with Barrett I am currently working on my Barrett Thesis under the supervision of Dr.Trembath-Reichert. We hope to better understand a special group of proteins called intrinsically disordered proteins (IDPs) and the implications they could have in astobiology and biotechnology.

Ronie Moore

My name is Ronie Moore and I am an undergraduate student majoring in Biological Sciences (conservation and ecology).

Veronica Mierzejewski

I am a PhD student at the School of Earth and Space Exploration studying astrobiology. My passion lies in finding the possible hidden physics that explain life while also understanding life's origins, functions, evolution and limits. My project involves characterizing the proteome of a microbial community that have been buried 2 kilometers beneath the subsurface for millions of years. The goal is to find evidence of their adaptation to this unique environment, and if no such adaptation exists, reveal that they can serve as a living time capsule for organisms 20 million years ago. In my free time, I love playing tennis, hiking, camping, running, visiting the Pacific Northwest, and cooking food with my friends.

Desmond Hanan

Desmond is a Master of Science (M.S.) student in geological sciences whose research focuses on microbial interactions with minerals and soils in arid environments. His interest in the interactions between biology and geology stems from his interest in astrobiology and research into how life could possibly survive in harsh and unusual environments like the surface of Mars. His is often tied to aspects of astrobiology and the search for extant life beyond earth. His first project is focused on figuring out how microbes can extract water from soils and minerals during long dry seasons and droughts when rainfall and other sources of moisture are rare. He is also working on projects analyzing how plant litter decomposes in desert microclimates. Outside of science, Desmond really enjoys volleyball, swimming and hiking. He often goes hiking around Tempe and Flagstaff, though his favorite place to hike is the organ mountains in New Mexico. Besides physical activities he also really enjoys singing, making music, and playing board games.
