Welcome!

Welcome to the echolab website at Virginia Tech. Our mission is to explore and develop methods to foster empathic interactions among individuals using computational systems. Our research is grounded in the empathy framework depicted below. It focuses on three key themes: computational tools for perspective sharing by empathizers, computers as an expressive medium for targets, and the facilitation of empathic communication for both groups. Additionally, we are committed to studying how to create safe environments where targets can be safely vulnerable.

To Prospective Students

Echolab is not recruiting any graduate students until otherwise noticed.

echolab is always looking for Ph.D. students who are interested in creating novel interactive systems. We are also looking for exceptional undergraduate students and master students to work with. Please apply to CS@VT.

If you are in Virginia Tech already and would like to do research in Echolab, please fill out the following survey and I will respond. https://forms.gle/gfsvheq8U6YNrGby7

We envision that echolab is…

  • A platform where members develop into independent researchers and achieve their career goals.
  • An opportunity for individuals to discover that giving—through teaching, helping, sharing, and collaborating—enhances their own growth and success.
  • A source of social capital that enables learning from each other.
  • A community where inclusion is prioritized, and members feel connected.
  • A group that contributes to society and the world by producing and disseminating new knowledge.
  • An environment where individuals can be more productive than in any other setting.
  • A socio-technical system designed to scale the above visions.
