Alina Nguyen (she/her)

4th year Ph.D. candidate in Integrative Biology

Hi, I’m Alina! I study how chemical treatments affect the brain and behavior of Xenopus laevis frogs. My parents came to America as refugees from Vietnam, and some time along the way they met in Minnesota and I was born 🙂 I grew up surrounded by the beautiful lakes in Minnesota and spent most of my childhood outdoors. I was curious about how and why the animals I encountered behave and that’s how my interest in science began. My goal, through education, is to promote inclusion and increase representation of minority groups in STEM.

Jackie Galvez (she/her)

2nd year Ph.D. candidate in Integrative Biology and Museum of Vertebrate Zoology

Hi friends! My name is Jackie and I’m a 2nd year student in the Integrative Biology department. I’m originally from the Los Angeles area and am the first in my family to pursue an advanced degree. I study dietary specialization and niche partitioning in Cameroon crater lake cichlids. Basically, I’m interested in what fish eat, how they eat it, and the connections between diet and evolution. In addition to research, I’m very passionate about K-12 science education. I’m involved in two programs here at Berkeley, Bay Area Scientists in Schools (BASIS) and Expanding Your Horizons (EYH), which provide grad student-led STEM lessons and workshops to K-8 students. Feel free to reach out to me about these programs! My non-science interests include bullet journaling, hiking, thrift shopping, and spending too much time (and money) at coffee shops. If you’re looking for someone to talk to about the enneagram or the latest episode of the Bachelorette, I’m your gal!

Meet the Graduate Student Coordinator of STEM*FYI

Ali Bhatti (he/him)

2nd year PhD student in Science and Math Education (SESAME)

Hello! I’m Ali. I was born in Pakistan and as a child, I immigrated to the United States with my family. We settled in Englewood, NJ and I consider myself a proud New Jerseysan. My identity is very much influenced by my cultural and religious upbringing as a Pakistani-Muslim growing up in the US post-9/11. I was always the “Muslim” kid in my classes and growing up in the tri-state area only accentuated that label. However, once I got to college, I began to see how my faith, culture, and science (particularly biology) were mutually reinforcing and connected. Now, as a grad student, I’m continuing to see those personal connections, which has led me to become interested in the science identity development of other students in STEM. Outside of being a grad student, I love sports, so you can catch me on the basketball court missing wide open 3’s or turning off the TV in frustration as my favorite teams (Nets, Mets, AC Milan) maintain their mediocrity.
