Peer Mentors

A set of four junior and senior MB&B majors serve as peer mentors for students who are considering or entering the MB&B major.  Peer mentors can give fellow students a sense of the experience of majoring in MB&B and practical advice on navigating the requirements and electives in our program. Peer mentors offer advice on which classes to take, experiences to consider and anything pertaining to the major. They can provide advice on how to take advantage of the many academic resources available to you, such as peer tutors, college tutors, teaching fellows, faculty office hours, etc.  Peer mentors also host informal community-building get-togethers in the department for prospective and current majors.  If you have not yet declared an MB&B major and want to be invited to these events, please email

Please note that peer mentors supplement the MB&B faculty academic advisors.  You should meet one of the faculty advisors to discuss details of the MB&B degree requirements, to get your schedule or other official forms signed, and to get faculty-level advice on things like setting up an independent research experience, planning a scientific career, etc.

Peer mentors for 2021-2022 are:

Raquel Sequeira,, Class of 2022, Timothy Dwight College

Raquel is interested in energetics at all levels, from physics to ecology, and especially how energy is transferred and transformed across those levels. She has done research in epigenetics and now works on modeling electron transport. Raquel is also a student of philosophy and literature, with a focus on Shakespeare scholarship and performance. She hopes to unite her passions for science and humanities in her work.

Mehana Daftary, Class of 2022, Benjamin Franklin College

Mehana is interested in biochemistry and disease mechanisms, and how our learning can inform rational drug development. She works at the Crews lab assisting in the development of PROTACS, which are chimeric complexes designed to specifically ubiquitinate and degrade target proteins. She is passionate about public health and epidemiology and hopes to continue to explore these interests during the rest of her time at Yale. Outside of academic interests, Mehana is the Yale Campus Girl Scout Secretary, serves as a coordinator for the Yale Community Kitchen, and is an officer in the Glee Club.

Daniel Guerra,, Class of 2022, Trumbull College

Daniel has been invested in learning about the crossover of the physical sciences and engaging in humanities at Yale. He has done research on the mechanisms of diabetes and recently worked in the lab of former MB&B professor Dr. Patrick Sung, focusing on tumor suppressors BRCA1 and BRCA2 and DNA repair processes. Outside of science, Daniel serves on YCC, as the Creative Director for Y Fashion House, and Publicity Director/Choreographer for Yale Danceworks.

Solomon  (Sol), Class of 2023, Pierson College

Sol is interested in exploring the biochemistry of the natural world and applying it to human health. This has led him to study the immune response to different types of cancer cell death at the Rothlin-Ghosh lab and marine natural product drug leads at the Scripps Institute of Oceanography. Outside of MB&B, Sol serves as the student coach of the Yale Men’s Club Water Polo Team, is a FOOT leader, and is a member of the Helix Incubator and the Yale Bridge Club.

Alice Zhang,, Class of 2023, Timothy Dwight College

As an MB&B and Anthropology major, Alice is particularly interested in biochemical explanations for disease, but also how cultural and social factors can impact how people view health and their access to healthcare. She conducts research in the Paulsen Lab, focusing on a particular mutation of the TRPA1 pain receptor (the “wasabi receptor”) and characterizing mutant channel activity, trafficking, and other relevant properties. Outside of class, Alice likes to go birding, visit natural history museums, dabble in arts and crafts, and read.
