Róisín graduated from Northeastern in May 2019 with a B.S in Bioengineering and a focus on Cell & Tissue Engineering. While at Northeastern, she completed three six-month co-ops working as a full-time Research Assistant at various biotechnology companies.

Her first co-op was at DOTS Technology Corp. where she assisted in R&D for the science behind a novel diagnostic platform for food allergens. Róisín’s second co-op was at Sanofi Pasteur as a member of the Viral Vectors & Delivery Group and FluNXT, an internal start-up to create a broadly-protective influenza vaccine. Her third and final co-op was at Jounce Therapeutics, working on an early discovery program for a novel T-cell focused cancer immunotherapy.

In the Shalek Lab, Róisín has been working with Marc & Travis on using Seq-Well to give further insight into M. tuberculosis infection. While here, she hopes to learn more about immunology, genomics and single-cell analysis!

Outside of science, Róisín has been working with Engineers Without Borders for the past five years. At Northeastern, she worked on and led the Uganda Program, whose goal was to construct a water distribution system for the community of Bbanda, Uganda. Róisín also helped to start a new water distribution project in Nakyenyi, Uganda. Now, she works with the Boston Professionals Chapter on similar projects in Mkutani and Chamhawi, Tanzania. Other interests include traveling, Hulu binging (Nextflix is old news), reading and spending time with her friends/family.
