Jamie's Project Page

Who:  I am from Kaysville, Utah and I came to U of U for the amazing science opportunities, the scholarships provided, as well as the unique volunteering experiences and clubs. In my free time, when I am not studying, I enjoy running, drawing, and hiking.

My scientific interests:  Since I was a child I have loved stargazing and possessed an innate curiosity regarding the world around me. This led to lots of questioning regarding the origin and expansion of the universe and is where my love of physics and chemistry was born. Furthermore, I am very interested in applying both my love of chemistry and physics to the human body.

Academic goals:  I am a biochemistry and kinesiology double major with a minor in astronomy. After earning my undergraduate degree, I plan to attend medical school or potentially to pursue a PhD in physics.

Career goals:  I plan to become a doctor as well as to get involved with clinical research. I am very passionate about helping others and would like to be involved in humanitarian work, where I can help the most vulnerable populations.

Little is known regarding the early universe, specifically during the appearance of the first stars and the reionization era. 21cm cosmology is a technique that allows for the study of the formation of stars, as well as neutral hydrogen in the interstellar medium, due to the ability of a 21cm wavelengths to pass through dust clouds. This ultimately allows for the detection of hydrogen gas throughout the universe. The effects of changing parameters of the early conditions of the universe is represented by differences in the 21cm signal which is obtained through the use of ARES simulation on CHPC virtual environment. The parameters that were changed in this work include the star formation rate, the star efficiency rate, as well as the redshift when sources turn on, all of which influence the 21cm signal. A change in star formation and efficiency rate shifted both the frequency at the absorption trough minimum as well as the width of the absorption trough. When the redshift that sources turn on was changed it altered the entire curve of the 21cm signal.  The 21cm signal’s obtained from simulations containing various parameters can be compared to the EGDES signal to gain insight into the conditions early universe.
