Undergraduate Research



Fall 2012-Present: Drops
  • Since Fall 2012, I have been working on the characterization of the lateral retention force on liquid drops sliding on surfaces.

  • So far, ten undergraduate students have participated in this project: Jason Dark, Fabian Garza, Alek Hutson, Huy Luong, Thomas Michael, Jared Richards, Anthony Simental, Jonathan Taylor, Ben Vizena, and Taylor Whitehead.

  • So far, we have published one paper,

    R. de la Madrid, T. Whitehead, and G. Irwin, Am. J. Phs. 83 (2015) 531-538; arXiv:1505.04104

  • Taylor Whitehead is one of only three Lamar undergraduate students who have co-authored an article that appears in a peer-reviewed journal.

  • Fall 2011- Summer 2012: NASA and wave machine
  • In Summer 2012, I supervised a group of eight undergraduate students who flew in NASA's ``Reduced Gravity Student Flight Opportunities Program.''

  • We were one of the only 14 projects selected for the 2012 campaign.

  • Eight undergraduate students participated in the project: Nicholas Allen, Aleiya Samad, Jacob Wright, Jessica Plaia, Kirk Goza, Zachery Jones, Alejandro Gonzalez, and Aaron Weatherford.

  • In this experiment, the students measured the effect of gravity on the dispersion of a torsional wave machine for 0-g and for 1.8-g.

  • Eventually, we published a paper on this subject with an undergraduate student (Alejandro Gonzalez):

    R. de la Madrid, A. Gonzalez, and G. Irwin, Am. J. Phs. 82 (2014) 1134-1141; arXiv:1409.0426

  • Alejandro Gonzalez was the second ever Lamar undergraduate physics student to co-author an article published in a peer-reviewed journal.

  • Fall 2011- Spring 2014: Railgun

  • We built a small prototype with a range of about one meter. However, due to safety concerns, we didn't build the full-scale model.

  • Eight undergraduate students participated in this project: Jacob Wright, Jessica Plaia, Kirk Goza, Zachery Jones, Alejandro Gonzalez, Aaron Weatherford, Paul Rizk, and Anthony Simental.
