My name is Thomas Bushart and I have a Ph.D. in Cell and Molecular Biology from The University of Texas at Austin.
I am currently a lecturer but am looking to change careers into the field of computer programming. I am looking for employment opportunities as an entry-level/junior software developer or software tester position. Please review my resume, portfolio, and LinkedIn and contact me if you would like to discuss a position. Please email me if you have feedback or suggestions for the site.

The phrase "this end up" is generally used in the context of shipping. It lets package carriers know which way to stack boxes to minimize potential damage to the contents. My use of the phrase isn't about shipping or packaging though! "This End Up" has layers of meaning to me:
  • Gravity: My Ph.D. work was on a model plant, the fern Ceratopteris richardii, whose single-celled spores could both sense and respond to gravity. The roots of most plants can grow downward in the absense of any other orientation feedback (like light or water), but that response involves interactions between many different cells and cell types. The "C-Fern" spores can do it all - with a measurable response - in a single cell only about 100 micrometers across.
  • Understanding: Knowing which way is up is important for plants and animals. We put our feet down and our heads up to move around. Losing track of "up" can be very confusing to people, and even deadly in sitations such as diving or flying. Knowing which way is up can help us get around in the world. So "Up" is also metaphor for understanding. I hope to be able to implement multiple "virtual manipulatives" to help others understand abstract concepts.
  • Perspective: "Up" is actually a relative term. Get far enough away from the surface of the earth, and it loses concrete meaning, there's only towards or away. My perspective is different than yours and so my understanding of the world is different. Both understanding and and perspectives change with time, which is why the site logo rotates.
The Fractions manipulative is my implementation of a request from Brian Stockus, the Curriculum Coordinator of Elementary Mathematics of Round Rock ISD. Brian wanted a tool that teachers could use with their students to explore fractions. Using it, students can observe how parts relate to a whole and how fractions of various denominators and numerators compare to each other.
The first manipulative (fractions) has been well received and is expected to see in-classroom use this year. A second manipulative is currently in the planning stages.
