About Me:

Hi, welcome to my page!

I am a PhD candidate in the Complex Biosystems department at UNL. Prior to joining this program, I earned my BS in Biology from Truman State University and explored another area of interest, earning my MA in Psychology at UNL

I have been part of the Systems and Synthetic Biology laboratory, since August, 2018. I work to develop synthetic biology tools for non-model bacteria with the goal to metabolically engineer industrially useful strains for bioproduction. Bioproduction involves taking a living organism, providing it with a nutrient source, and allowing the living system to create a chemical of interest. For example, one of my projects involves feeding corn waste to a bacterium to produce a molecule used to create bioplastics. Bioproduction has potential to replace non-sustainable methods, such as those that require petroleum. My PhD work focusses on using non-model organisms that already possess interesting native characteristics and optimizing them for bioproduction through synthetic tool design and metabolic engineering. The metabolic engineering strategies are predicted from genome-scale computational models constructed by myself and other members of my lab. The combination of computational modeling and experimental implementation allows for a design-build-test cycle that ultimately results in organisms tailored to bio-produce important chemicals.  

 

My current projects involve 
i) Development and analysis of a genome-scale metabolic model for the analysis of Paraburkholderia sacchari
ii) Metabolic engineering of Paraburkholderia sacchari for bioproduction of bioplastics (PHB and PHBV); and
iii) Metabolic engineering of Actinobacillus succinogenes for bioproduction of succinic acid.

Outside of work, I like to spend my time exploring in nature, reading in my hammock, attempting DIY projects, and spending time with family and friends.
