CCNY Rich Summer Intern - Adrian Cabreja

Sept. 10, 2021

Adrian Cabreja is a masters student in Mathematics at CCNY. He is also a recipient of a Dr. Barnett and Jean Hollander Rich 2021 Summer Internship, working with Prof. Sean Cleary.

Hear more about it from Adrian himself!

My name is Adrian Cabreja and I interned for Professor Sean Cleary this past summer. The duration of my work consisted of studying important groups in geometric group theory, i.e., Thompson’s group, Houghton’s group, and automaton groups. Additionally, I studied the notion of measure in the context of group theory.

The opportunity to concentrate solely on mathematics during the summer allowed me to develop my mathematical intuition, my ability to understand complicated mathematical literature, and my ability to write multiplexed proofs. I am very fortunate to have been given the opportunity, for it also solidified my research interests.

I thank Professor Cleary for his wisdom and guidance and my partner Clarisselle for her unwavering support.
