About Me[edit]

I am a student at Humboldt State University in Arcata, CA. I am working towards a degree in Environmental Resources Engineering. I hope to use this degree to help others in a way that challenges and interests me.


Environmental Resources Engineering


-In the Engr215, Introduction to Design class, my team was responsible for the designing a composting toilet for the CCAT house, which we dubbed The CCATBox.

-For this project, my team made a Design Document that details our design problem, literature review, alternative designs, decision process, and design implementation.

-To keep track of time spent on the project, I created this Time Sheet.

-Our group also created this Gantt Chartto help us keep our project on task.

-Here is an example of an Auto CAD drawing that I made for engr215.

-Here is an example of a Memothat I wrote to submit a draft of the The Bottoms wildlife pond greywater plumbing web site I helped to create with a partner.
