TPSS Student Organic Farming Training (SOFT) is a diverse group of undergraduate and graduate students who share common interests in growing food sustainably and having fun. SOFT was initiated in 2007 and the SOFT Student Farm began in the spring of 2008 with a handful of students and faculty dedicated to creating a place for student exploration and leadership in agriculture. Since then, the farm has flourished, producing wonderful things to eat and a great community of lively students.



Every year, graduate students are elected for the TPSS Graduate Student Oganization (GSO). For the 2015 - 2016 school year, the TPSS GSO officers are:

  • Kauahi Perez - President
  • Tia Silvasy - Vice President
  • Greg Hoover ​- Secretary​
  • Aimee Uyehara - Treasurer​

The TPSS GSO strives to enrich the graduate student experience in our department by orchestrating social events and activities. The goal of these events is not only to provide camaraderie among students outside of the classroom and laboratory, but also to bring the entire department together, including faculty and staff, for informal events.

Annual Waffle Party

Before the start of the Fall semester, Dr. Ania Wieczorek, the TPSS Graduate Program Chairman, hosts a waffle breakfast for the TPSS graduate department to introduce incoming new graduate students and faculty members. It's a time to sit, eat and get to know new and old faces. And enjoy delicious waffles made by the graduate program chairman!
