Meet our 2020-2021 Executive Board!

Karin Kartawira


Major: Public Health Studies

Hometown: Cary, NC

Favorite Bible Verse: Romans 8:28

“I thought that Hopkins was a perfect place to plant a GMMA branch because a lot of students are interested in entering the field of healthcare. I trust that God can use me and grow me as we start this chapter, and I wanted to be in a position where I can learn to rely on Him more and not on my own abilities, especially in leading other people. I ultimately want to see our community grow and to be able to spread His light and truth throughout Baltimore!”


John Han

Co-Vice President (Internal Affairs)

Major: Electrical Engineering

Minor: Computer-Integrated Surgery

Hometown: Placentia, CA

Favorite Bible Verse: Romans 5:8

“Coming to Hopkins, I knew about the brokenness of Baltimore, but there was no easy access to serving the community, especially in a Christ-centered way. I knew that there were others like me, and discovered GMMA, a national organization that does just that: creates a Christian community of servant leaders. I personally am very excited to join GMMA in their mission to empower future healthcare individuals, while outreaching to those who do not know Christ in Baltimore.”

Hami Kang

Co-Vice President (External Affairs)

Major: Public Health Studies

Hometown: Hopewell Junction, NY

Favorite Bible Verse: Romans 8:28

“GMMA’s core goal of just spreading the message of Jesus’ healing and love is something that really resonated with me. It’s such a simple message. GMMA gives an opportunity to serve the community through health with the purpose of spreading God’s love and serving Him.”

Sarah Yao


Major: Public Health Studies

Minor: Computer Science

Hometown: College Station, TX

Favorite Bible Verse: Romans 8:38-39

“The mission of GMMA to go out and be the ones to spread the word, both on campus and worldwide, really spoke to me, especially in accordance with Romans 10:14-15, this verse, combined with the Great Commission, inspired me to join GMMA. Particularly since healthcare is such an impactful, time-consuming field, it’s important to stress and prioritize our faith and actions that proceed from that faith.”

Joshua Kim


Major: Computer Science

Minor: Applied Mathematics and Statistics

Hometown: Lewisville, TX

Favorite Bible Verse: Joshua 1:9

“I used to be interested in premed and through GMMA I can still make an impact. Although GMMA is about healthcare and medical missions, I hope that through this people at Hopkins can get to know God. I’m excited about missions but I hope we can help the community of Baltimore through GMMA. Even though we are starting a new chapter I am excited to help it grow in the next couple of years!”

Sejean Yang

Public Relations Chair

Major: Public Health Studies

Minor: Psychology

Hometown: Fairfax, VA

Favorite Bible Verse: 2 Corinthians 12:9

“I decided to join GMMA after our President introduced me to the organization. I loved what GMMA was about and how it combined ministry and healthcare. I thought it was a great way to meet people with similar interests and to reach out to underclassmen who may be in need of a community. In addition, I’m looking forward to getting more involved in the Baltimore community.”

Grace Lee

Missions Coordinator

Major: Psychology and Molecular and Cellular Biology

Hometown: Cherry Hill, NJ

Favorite Bible Verse: Matthew 5:4

“Though there are times where all I do is cry, doubt, and stumble, His grace has never failed to humble me and bring me back to Him. I love that His Word sanctifies me as it continues to become more real in my heart. These experiences with God are what drew me to GMMA. I want to live out the Gospel and join God in His work: grow in faith together with my brothers and sisters, find freedom in counting others more significant than myself, and share the hope that I find in Jesus and cling to every day with others.”

Wilson Liou

Missions Coordinator

Major: Biophysics and Computer Science

Hometown: Belle Mead, NJ

Favorite Bible Verse: Psalm 90:14

“While talking and listening to the leaders of the Hopkins GMMA chapter, I saw that they were highly motivated and committed to growing the missional mindset of Christians here on campus. I wanted to challenge myself to strive to pursue missions in my own local community and encourage my fellow classmates and campus mates to do likewise. I believe GMMA provides a great outlet for Hopkins students to grow in their heart for missions and better understand how serving in healthcare and medicine can be closely tied to serving in ministry.”

Qing Lu

Missions Coordinator

Major: Neuroscience

Minor: Computer Science

Hometown: Gainesville, FL

Favorite Bible Verse: 2 Corinthians 12:9

“It’s really easy to lose sight of why I want to be a doctor and get overwhelmed with the day-to-day tasks needed to ‘build my resume’. I wanted to join GMMA because I need a constant reminder that my desire to practice medicine and to know and serve God are not mutually exclusive. God calls us to serve Him in everything we do and that includes our future careers.”
