Bio Sketches

Adriana Salerno (Bates College)

Adriana Salerno is originally from Caracas, Venezuela, where she received her undergraduate degree in mathematics from the Universidad Simon Bolivar in 2001. She then went on to earn her PhD at the University of Texas. While completing her doctorate in mathematics, Salerno was also selected as the AMS-AAAS Mass Media Fellow in the summer of 2007; as such, she wrote articles for the Voice of America. Salerno’s main research area is Number Theory, in particular the intersections of number theory with geometry, physics, and cryptography. She is also very interested in the communication and teaching of mathematics to create a more inclusive and equitable STEM workforce. She is an alumi of the Linton-Poodry SACNAS Summer Leadership Institute, and the SACNAS-HHMI Advanced Leadership Institute, and is committed to increasing the representation of minorities and women in the mathematical sciences. She is a proud member of AWM, SACNAS, MAA, and AMS. Salerno was visiting mathematician at the Mathematical Association of America’s headquarters in Washington, D.C., from September to November 2016.

EDI Statement

I believe that everyone is a math person, that learning mathematics should be equal parts joyful and challenging, that to learn mathematics one must do mathematics, that no one should have to leave their identity at the door, that mathematics is not neutral, and that we are all better at mathematics if we work together.

EDI Statement

Equity, diversity, and inclusion (EDI) have been issues of deep concern to me for decades. As I awakened to the impact of systemic inequities on the field of mathematical sciences, I have made a concerted effort to ensure that EDI is woven into the fabric of my professional practice and that of the institutions where I serve. In my current role, I have endeavored to implement a culture of inclusivity and to eliminate bias and discrimination at every level of the institution from the Building Manager to the Chair of the Board of Trustees. EDI are complex issues requiring multi-faceted solutions which I hope to explore as a member of the EDI Board of BIRS.

EDI Statement

I am committed to making mathematics and STEM more inclusive. As a gay man, I recognize the challenges faced by underrepresented members of the mathematical sciences community, especially those who are BIPOC or LGBTQ+. Positioning equity, diversity, and inclusion into the DNA of academic institutions such as BIRS is an essential step forward.

EDI Statement

It's a dangerous myth that mathematics functions as a meritocracy. More often it's the case that those of us who have been blessed with a high degree of professional success reinforce structures that are designed to help those students who are most like ourselves advance through the academic pipeline.

I was very lucky to have discovered my love for mathematics early and to have mostly felt at home among my mathematically-inclined peers, but not everyone feels like they belong in the math department common room. It’s a problem if an instructor uses language that suggests that certain arguments are trivial or that this is something that everyone knew from the cradle. These tropes are very alienating to people who, for one reason or other, did not learn about modular arithmetic in kindergarten. We have to figure out ways to be allies and mentors for aspiring mathematicians who are not having the same experiences that we did.
