Jo and her dog Runa

Jo (she/her) is a fifth year PhD candidate in Environmental Engineering. This is her fifth year in the GSA and her first year as the Chair after serving as the CTF director for two terms and one term as the Vice Chair. Her research focuses on identifying and understanding non-traditional sources of air pollution in urban areas. Before Yale, Jo received a degree in Environmental Engineering and Integrated Science from Northwestern University. Through her position in the GSA, Jo is excited to work with GSA representatives and GSAS to ensure that GSA is helping advocate and support graduate students in all divisions.  

Roxanne Morris, Vice Chair

Roxanne Morris  Roxanne (she/her) is a fifth year PhD candidate in the Microbiology Program. This is her fourth year as a representative and her first year as the Vice Chair. Her research uses single cell techniques to investigate how an environmental bacterium, Pseudomonas aeruginosa, successfully infects the lungs of people with cystic fibrosis. Through the GSA, Roxanne hopes to raise graduate student voices and advocate for improved graduate student education for all. Outside GSA and the lab, Roxanne enjoys walking in West Rock, going to museums, and eating out in NYC.

Christopher Lindsay, Secretary

Jo and her dog Runa Christopher (he/him) is a third year PhD candidate in the Department of Astronomy. Christopher’s research focuses on stellar astrophysics, how stars are born and evolve over billions of years. In particular, Christopher explores how long time series observations of stellar oscillation modes can be used to study interior processes and structure of stars.  Christopher received degrees in Astronomy and Environmental Studies from the University of Southern California. This year is Christopher’s second on the GSA and first year serving as a GSA Officer. 

Bugra Sahin, Treasurer

Bugra Buğra (he/him) is a third year PhD in Chemical and Environmental Engineering. This is his first year as both a representative and the treasurer. His research focuses on stimuli responsive nano composite materials for water treatment and desalination. Buğra completed a dual degree in Chemical Engineering and Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign before coming to Yale. He hopes to do work in the GSA to ensure better protections and easier transition to a new country for the international graduate student body, alongside helping to improve the graduate student life and experience in general as well.

Committee Chairs, 2022-2023

Katie Chang, Academics and Professional Development Committee Chair

Katie (she/her) is a 2nd year Ph.D. student in the Physics department. This is her second year on the GSA. She is working in Quantum computing theory, investigating topological quantum error correction code performance under biased noise. Prior to graduate school she completed her Bachelors of Science in Physics at the University in Virginia in 2021 with a specialty in computational medical physics and did a research project at Cornell on extracting quantum phase transitions from x-ray crystallography data. In her spare time, she likes to draw and learn stringed instruments. She is excited to serve as APD committee chair and work with her colleagues to enforce clear and high-quality advising guidelines, and bring a diverse set of academic and career development opportunities to the GSAS student body.

Shannon Rainsford, Conference Travel Fund Director/Committee Chair

Shannon Rainsfortd

Shannon (she/her) is a third year PhD student in Genetics co-mentored by Zachary Smith and Bluma Lesch. Her work focuses on the epigenetic influences of the male gamete on early embryogenesis. Prior to Yale, she graduated with a B.A. in Biochemistry and Molecular Biology, and an M.A. in Biotechnology from Boston University, and worked at a start-up in Cambridge, MA. This is her second year as a GSA representative and first year as CTF Director. She looks forward to working alongside the GSA and GSAS to supply funds for graduate students sharing their work with the world. 

Faith Taylor, Diversity, Equity, and Inclusion Committee Chair

Faith Taylor

Faith (she/her) is a second year PhD student in the School of the Environment. She is a DMV (D.C, Maryland & Virginia) native with a passion for understanding how marginalized communities in the United States are impacted by environmental racism and environmental injustices. She holds a B.S in marine science-biology from the University of Tampa and an M.S in marine, estuarine and environmental sciences with a concentration in environment and society from the University of Maryland- College Park. Faith is a proud member of Zeta Phi Beta Sorority, Incorporated. In her spare time Faith enjoys trying new vegan restaurants and gardening. She is excited to serve as the DEI committee chair and hopes to use her position to advance the efforts to make Yale grad students more diverse and better serve the diverse students that are already on campus. 

Victoria Rai, Facilities and Healthcare Committee Chair

Victoria (she/her) is a third year PhD student in Cellular & Molecular Physiology jointly mentored in the laboratories of Joseph E. Craft and Michael J. Caplan. She graduated with a B.S. in Biophysics and B.S. in Economics from the University of Michigan and worked in Chicago prior to coming to Yale. This is her first year in GSA and first year as the Facilities and Healthcare Chair, but brings experience from being a co-leader of the Graduate Student Disability Alliance at Yale and her involvement with the Crohn’s and Colitis Foundation to this position. Victoria hopes to continue to advocate for accessibility and healthcare needs of graduate students, bring existing projects to completion, and expand equity and inclusion projects in the graduate school. 


Jane Lee, Service Committee Chair

Jane Lee

Jane (she/her) is a second year student in the Computer Science department. Her general research interests are in machine learning theory, particularly in understanding and proving why various machine learning algorithms are effective. Prior, she studied mathematics, computer science, and statistics at University of Pennsylvania. She is passionate about equal access to education and opportunity, volunteering with educational non-profits including the SMART program and TEALS for the past 3 years. She hopes find ways to help improve the graduate student experience at Yale and the New Haven community at large during her tenure this year on the GSA.

Will Chadwick, Transit and Security Committee Chair

will chadwick

Will (he/him) is a third year PhD student in Cell Biology in the LusKing laboratory where he studies compartmentalization of the nucleus in fission yeast. This is his first year as a GSA representative and first year as chair of the Transit and Security committee. Before coming to Yale he received bachelor’s degrees in Cell and Molecular Biology and in Classics from San Francisco State University, and a master’s degree in Cell and Molecular Biology. He recognizes the importance that transportation and security have in ensuring a healthy and safe environment for graduate students and is dedicated to improving and sustaining Yale’s current systems.
