Joseph Evans
J. Alfred Smith, Sr. Professor of Theology in the Public Square Director, Center for Truth, Racial Healing & Restorative Justice
I am working on developing an antithesis rhetoric to create priestly and prophetic functions. This opens critical space in order to lament conditions caused by perpetual existential crisis and then demand that restorative action be taken on behalf of oppressed people groups. I enjoy sports, biking, and hiking and jazz masters like Louis Armstrong, Billie Holiday, Sade, Dizzy Gillespie and the second Miles Davis Quintet, (Ron Carter, Herbie Hancock, Wayne Shorter, and Tony Williams).

Samuel Joseph Kim
Instructor
My work focuses on how modern leaders of ministry can change, grow, and create according to the context of their missional call. I am constantly seeking to answer the question, "How can we love God and our neighbor well, given the current situation we are living in?" My dissertation synthesized a theologically grounded approach to Human-Centered Design Thinking that can be useful for the local church in helping to recognize entrenched mindsets and embark on a new paradigm that embraces curiosity, adaptability, and humility.

Sangyil Sam Park
Professor of Preaching and Director of the Doctor of Ministry Program
Having been born in a non-Christian family in Korea, I had never been part of any faith tradition until I was a youth. One summer in high school, I felt my heart warmed when I attended a weekday service at a small Methodist church and that changed the course of my life. After working for a few years after college, I went to the Methodist Theological Seminary in Seoul and came to the United States as a student in 1991. As an ordained servant of the Lord, I always identify myself as a preacher/pastor; I love preaching and enjoy being part of a church community. It has been a blessed 30-plus years for me to have been working with people of God in ethnically and culturally diverse congregations throughout the United States.

Eric Sias
Associate Professor of Biblical Studies and Director Latiné Programs
When he is not busy working with his beehives or lavender plants, Eric is in active conversation with the letters of Paul and ancient biblical purity laws. As the son of a Mexican immigrant and an American copper miner of Mexican descent, he has come to use his life-long experience of cultural liminality to find a deeper understanding of the boundaries of the sacred and profane in the book of Leviticus, and how early Christians interpreted these spheres of existence when considering the death of Jesus. His academic goal is to provide the tools of biblical scholarship to future leaders of the Latina/o church to help bridge the gap between the ancient laws and norms of the biblical world and modern society.
