How to join the NYLI

Antonio Alexander

Antonio Alexander


Bloomfield, Connecticut

Hey there, I'm Tony, short for Antonio Alexander, a 20-year-old from the vibrant city of Hartford, Connecticut. Currently, I'm pursuing General Studies at Manchester Community College, exploring different fields that spark my interest. Besides being a college student, I am also a photographer and an aspiring creative. I took my passion for photography to the next level by establishing my very own photography company. Capturing moments and preserving memories in a unique way brings me immense joy. But my journey is not just about personal growth; it's about making a positive impact on the lives of others. That's why I'm deeply involved with various non-profit organizations that focus on providing opportunities to children who are passionate about photography, videography, and other creative pursuits. Empowering these young minds and helping them discover their talents is incredibly fulfilling. Ever since I was little, I've been an active participant in HFA (Hartford Fine Arts), and their activities have shaped my artistic spirit. Now, I want to give back to the community that nurtured my passions by becoming a pillar of support and a role model for other children. Together, let's inspire and create a brighter future for the community we hold dear.

Eliza VanZweden

Eliza VanZweden


Schoolcraft, Michigan

My name is Eliza VanZweden, and I am a 23-year-old woman living with a rare bleeding disorder called Glanzmann’s Thrombasthenia in which my platelets don’t work. I recently graduated with a Master’s in Biomedical Engineering, and I currently work as a process engineer in manufacturing cell therapies to treat cancer. In my free time, I enjoy crocheting, hiking with my dog Rocky, and attending sessions hosted by my local chapter, the Hemophilia Foundation of Michigan. A fun fact about me is that I am a certified Cheesemonger and I also used to raise alpacas on my family’s farm. I am looking forward to learning more about Advocacy, Education and Research through NYLI and volunteering with my local chapter!

Vinh Tran

Vinh Tran


Monroe Township, New Jersey

Hello! I'm Vinh Tran, a Molecular Biology and Biochemistry major at Rutgers Honors College. Alongside my studies, I work as a Phlebotomist, drawing upon my passion for understanding the intricacies of the human body. Living with Hemophilia A, has inspired me to delve deeper into the field of hematology and I hope one day to work as a Hematologist. Currently, I conduct research at the Anthony Lab, investigating asparaginase, a drug to treat acute lymphoblastic leukemia, aiming to contribute to advancements in cancer treatment. When I'm not immersed in the lab or hitting the books, you can find me on the mats as part of the Rutgers Brazilian Jiu Jitsu Club.
