Current Officers (January 2015 - present)

Yvonne Chang – President

Advisor: Susan Tilton         E-mail: 

Hi! I’m a third year graduate student in the Toxicology PhD program. In the Tilton lab, my research consists of building a predictive model to assess carcinogenic risk of chemical mixtures with systems biology data generated from a 3D human respiratory model. I am passionate about educational equity, and TEAM Tox is a great place to build community and increase engagement with students. I earned my B.S. in Cell Biology from the University of California, Davis, and I am native to San Francisco. In my spare time I enjoy tacos and kayaking.

Prarthana Shankar - Vice President
Advisor: Robyn Tanguay          E-mail: 

I am a second year PhD student working in Dr. Robyn Tanguay’s research lab. I am interested in studying the downstream targets of aryl hydrocarbon receptor activation by polycyclic aromatic hydrocarbons (PAHs) and their role in toxicity. Outside of work, I love hiking, traveling, trying new food, hanging out with animals, and binge watching TV shows. I am from India and I really miss my family and the warm beach!

Martin Pearce - Treasurer and Secretary
Advisor: Siva Kolluri         E-mail

I am a fourth year Molecular and Cellular Biology PhD student working in Dr. Siva Kolluri's lab. My research focuses on the Bcl-2 family of proteins and their role in therapy resistant cancer. My research goal is to identify strategies to treat therapeutic resistant cancer. I joined TeamTox to become more involved in departmental activities and reach out to the community to communicate and share science knowledge. Outside of the lab, I enjoy playing soccer, hiking and mountain biking. 

Alix Robel - Academic Programs Committee Grad Representative
Advisor: Jennifer Field          E-mail:

I am a third year graduate student in Toxicology, working with Dr. Jennifer Field. I am currently working on per- and polyfluoroalkyl substances (PFASs) in aqueous film-forming foams, groundwater, and landfill leachates. My hobbies include cooking, yoga, and anything crafty. I joined TEAM Tox to get more involved in the activities of the department and engage with the community.

 Raymmah Garcia - Student Faculty Liason 
Advisor:           Email:

My name is Raymmah(rye-ma) Garcia & I'm a fourth year graduate student in the Chemistry department. My research focus is on hydrocarbon surfactants in Aqueous Film Forming Foams (AFFFs) and AFFF-contaminated groundwater. In my spare time I practice Jiu-jitsu otherwise known as 'The Gentle Art'.

Serhan Mermer - Co- Student Faculty Liason
Advisor: Jennifer Field          E-mail:

I am a fourth year graduate student in Horticulture Department and working with Dr. Jennifer Field in Environmental and Molecular Toxicology Department. My research focus includes residue of insecticide and their metabolites in fruits including grapes, blueberry, and cherry and wine. Besides being a graduate student, I like to play soccer, dancing salsa, cooking delicious food, hiking, biking, and camping.

Brianna Rivera - Social Fundraising Chair
Advisor: Susan Tilton          E-mail:

I’m a first year EMT graduate student. My research interests include linking human exposure to environmental contaminants with the development of disease, and using computational approaches to identify mechanisms of toxicity. I received my B.S. in Biology from the University of Pittsburgh in Pennsylvania. In my free time I enjoy hiking,biking, camping, traveling, and exploring Oregon.

Carolyn Poutasse - Outreach Chair
Advisor: Kim Anderson         E-mail:

I am a third year EMT graduate student in Dr. Kim Anderson’s laboratory. I received my B.Science in Chemistry from Haverford College, PA. My research uses silicone passive sampling devices to explore personal chemical exposures of career firefighters and hyperthyroid cats (separate projects, equally interesting). My hobbies include biking, swimming, singing in choir, and performing in community theater productions.

Daniel Elson - Outreach CoChair
Advisor: Siva Kolluri          E-mail: 

I am a second year graduate student performing research in Siva Kolluri's lab. I have a B.S. in Biology from Point Loma Nazarene University in San Diego. My research interests include cancer biology, nuclear receptor signaling, identification of novel drug targets, and developing therapeutics to overcome tumor resistance mechanisms.


Elaine Jennings - Outreach Committee Member
Advisor: Jennifer Field 

Studying environmental fate and transport of pollutants. Nature lover and outdoors enthusiast who enjoys swimming, hiking, and spending quality time with her cat.

Stephanie Krail - Outreach Committee Member

I am a first year graduate student in the EMT department. I’m working with Dr. Jeffrey Jenkins to research the impacts of pesticide exposure on aquatic receptors.
