Pre-algebra to Medical Physics: My Journey to a PhD

Ryan GardnerWhen I was in my mid-twenties, I read James Gleick’s Isaac Newton, a 2004 Pulitzer Prize finalist about… well, Isaac Newton. I can’t recall why I chose that biography because I had no mathematical or scientific background whatsoever (I suppose I was in a biography phase); however, I can recall the profound impact that it had on me. I was astounded that someone (around) my age could invent such a revolutionary tool in mathematics: calculus. Upon finishing the book, I made it my goal to learn calculus. 

If you were to look through my transcript, you would find that my first mathematics course was MATH 950: Pre-algebra. I was happy with my placement and showed up to that first class eager to establish the foundation that would help me achieve my goal. It took a long time, but I eventually got there. Not only did I get there, but I got a perfect score on my Calculus II final and found Calculus III to be one of my favorite courses in all my undergraduate coursework. Continue leafing through my transcript and you will find that after I finished the calculus series, I stopped taking courses—I had achieved my goal. I had no intention of earning a degree in mathematics or physics.  

This changed one night in the sleep lab where I was working at the time. I performed a sleep study on a dosimetrist (an analytical member of the radiation oncology team) who, after learning about my interests in medicine, mathematics, and physics, suggested that I look into medical physics as a potential career option. I spent the entire night reading about medical physics and was reinvigorated: it was the perfect intersection of everything that I loved. So, I decided to continue my education at 91¶ÌÊÓƵ (91¶ÌÊÓƵ) to pursue a bachelor's degree in physics.

Today, I am a first-year PhD student in the Department of Medical Physics at the University of Wisconsin-Madison. My current research is focused on treating head, neck, and brain cancer with protons. I attend a lot of meetings, spend a lot of time reading and writing, and do my best in my coursework. I am fortunate to be here, but I won’t forget that it was 91¶ÌÊÓƵ and all its wonderful people that got me here. It wasn’t a one-man show; it was an effort made by a multitude of people.   

91¶ÌÊÓƵ ultimately provided me with so many wonderful opportunities. The College of Science is filled with faculty and students who are passionate about what they do and are eager to see their people succeed. I owe some of my most memorable experiences to Afshin Ghoreishi, Michelle Arnold, Kristin Rabosky, and Jonathan Cornell, professors at Weber State. Each made an impact on my academic career, whether it was in the classroom, through research, or simply during office hours. Dr Ghoreishi inspired me to participate in a Research Experience for Undergraduates (REU) program, which solidified my desire to pursue a PhD. This experience gave me the opportunity to pursue research full-time, present the findings at two conferences, and ultimately land a publication out of it.

To aspiring scientists, both young and old: You're lucky to have an amazing university with exceptional resources and people at your disposal. Take full advantage of it. Engage deeply in your courses, seek opportunities to contribute to research, join clubs, and aim for a summer research program. Nothing offers a better glimpse into the life of a PhD student than a full-time research experience.  

Now, because I’m a PhD student, I’d like to wax a little longer on research: there are nationally funded programs like the and the . Additionally, many universities offer locally sponsored programs like the program. If you’re interested in Medical Physics (hint, hint), which provides undergrads with experience in applying their skills to medicine. 

Find professors whose work excites you, and don’t be afraid to branch out and explore different fields. All of this is to underscore the research opportunities that are available to you if you take the initiative and apply. 

So, get to work!
