I am a Social Psychology Ph.D. student. Before attending university, I served nine years active duty in the U.S. Air Force. As my military contract ended, I became curious about scientific research and saw it as my next place of service. During undergrad at UC Colorado Springs, I learned people often become less afraid of death after taking psychedelics and I began to wonder “how" and "why?” I now conduct research at the intersection of Experimental Existential Psychology and the Psychedelic Sciences where I have developed a theoretical model that answers the how and why.
In addition to my interests with research and teaching in Psychology, I am also earning my Graduate Certificate in Science Communication. Following in the footsteps of Carl Sagan, I want to contribute to a scientifically literate society.
The intersection of experimental existential psychology and the psychedelic sciences.
Using theory and empirical validation to develop a model that explains how and why psychedelics – with a supportive therapeutic context and proper integration – have so much therapeutic value.
