Office: Cos 115
I graduated from STAC with my BS in Biology in 2013 and my MST in 2015. I began teaching Chemistry Labs at STAC as an adjunct before moving into my current position as Lab Coordinator and Biology Lab instructor. I am sometimes referred to as the "turtle lady" due to the many turtles and tortoises I have rescued over the years and my office is often a place where people come to visit theses turtles and other animals I have.

Meghan De Witt

Office: Costello 203
Dr. De Witt grew up in an army family, traveling all over the world, and thinks this is why New York (containing the entire world in one city) is the perfect place to settle down in. She attended Brigham Young University and then the University of Wisconsin at Madison studying pure mathematics, before quickly realizing that applying mathematics to the world is the fun part of life. She is the 3D printer/lego/toy guru on campus, with an office full of all of these for anyone's enjoyment when they want a break from school work.
