ABOUT ALEXANDRIA JOHNSON

Screenshot 2023-06-28 at 5.22.25 PM.png

My name is Alexandria Johnson and I’m an undergraduate student at the University of South Florida majoring in Applied Mathematics. I am proficient in MATLAB and Excel and I have research experience in mathematical modeling for prostate cancer. I have good leadership skills and experience and I love to get involved in my local community. My goal is to earn a PhD and implement research in mathematical biology. I am passionate about groups of people who face health disparities and that is where I want to center my research.

Aspiring Mathematical Biologist

Goals

My goals are to become proficient in more computer languages, earn a PhD in Mathematical Biology, and conduct research in Mathematical Biology with a focus in health disparities.

ACCOMPLISHMENTS

  •  In February of 2023 I was awarded with a first place prize for an undergraduate poster in data science, convergence science, and mathematics

  • In January of 2020 I was awarded with a certificate of apprecition from the American Legion Post 46 at the 25th Annual Martin Luther King Jr. Celebration. The award was for my outstanding service and assistance which contributed to the advancement of the community programs and activities dedicated to God and Country.

  • In December of 2019 I recieved My Associate of Arts Degree from St. Petersburg College.

Moffitt Center Mathematical Oncology Department | Tampa, FL 

  • Mentored by Dr. Renee Brady and Dr. Heiko Enderling.

  • Worked with Dr. Brady on modeling prostate cancer.

  • Learned how mathematics is used to predict how a patient will respond to intermittent androgen deprivation therapy.

  • Worked in MATLAB on a model that was a little different from Dr. Brady’s original model.

  • Determined the predictive power of that model and compared it to the predictive power of Dr. Brady’s original model.

  • Used patient data to determine their exponential growth and decay of PSA when they are off and on treatment.

RESEARCH ASSISTANT

 

 

I was first a research trainee in 2019 at the Moffitt Center in the Integrative Mathematical Oncology Department. I worked on a project related to Intermittent Androgen Deprivation Therapy for Prostate Cancer. Here I began to learn how to utilize mathematical models to predict and describe patient response dynamics and how the power to predict responses to various treatment techniques such as treatment cycling chemotherapy, immunotherapy, and radiotherapy may result in improvements that minimize complications and extend survival.​

 

 

 

 

 

 

I have since continued working at Moffitt since 2021 investigating if PSA dynamics differ between black and white prostate cancer patients. I enjoy participating weekly journal clubs and collaborations where I receive constructive feedback for fellow lab members.I hope to continue to work in a collaborative environment like this through grad school and wherever my professional career takes me. Another unique opportunity I've had is hearing from patient advocates who  represented patients’ individual needs and feelings. This has provided a reminder to not get too caught up in just the math and remember that I am doing this to help real people.

CONFERENCES

One of my favorite parts of research is the opportunity to attend conferences. Making new connections and learning about the new and exciting research is an invaluable experience. Ensuring that I'm able to translate my research to all kinds of people is important to me and conferences have given me the opportunity to do this by bringing people with diverse backgrounds and experiences together.
