Biography

I finished my Bachelors degree in Biology with a minor in Chemistry in May 2019 from VCU. Following my graduation I worked for the Federal Government dealing with quality assurance in fuels for the Department of Defense. This position required an understanding of organic chemistry and microbiology since these are major contributing factors in the determination of fuel quality.

While in school I volunteered for two semesters as a Preceptor for Biology 151 and 152 (General Biology for science majors). 1-2 times a week I would hold an hour long lesson that covered challenging concepts such as the Kreps Cycle or Photosynthesis.

During my last semester of school I also undertook graduate level coursework in molecular genetics and volunteered at the Massey Cancer Center as a histological technician where I was eventually employed the following summer.
