Liam has worked on GSSC as Vice President of Campus Life and contributed to The Columbia Spectator as a cartoonist.

At Columbia, he is involved in men’s lightweight rowing and hopes to attend both divinity and law school, after which he hopes to re-enter public service as an attorney. In his spare time, Hunter enjoys NYC dining culture and is a loyal fan of the Metropolitan Opera.

Peer advisor Raysa Schumacher

Raysa Schumacher
Raysa was born in Colombia, but moved to Miami, Florida at six years old. She attended Florida International University right after high school, but decided that college was not the best decision at the time. She jumped into the workforce—working in the airline industry as a flight attendant and as an esthetician. Raysa decided to go back to college in spring 2019 to earn her Associate’s degree at Palm Beach State College. Upon graduation, she received admission to Columbia in 2020 to pursue her degree in Astrophysics. She hopes to continue on to graduate school to pursue a PhD. In her free time, Raysa enjoys reading, kayaking, crossfit, and spending time with her husband and dogs.
