Thalsa Mekaouche
Fellowship & Events Director
Thalsa-Thiziri Mekaouche is a first year in Branford College and a prospective Global Affairs major. Daughter of Algerian parents, she has always lived in Marseille, France. She is fond of cooking and is always up for anything outdoors! Her favorite author is Albert Camus, a French writer born in Algeria. Like him, her life has been inextricably linked to the Mediterranean. She loves its history, its landscapes, and the sun, which has nurtured both its fertile soil and countless communities over thousands of years. With PDLI, she hopes to understand how conflicts impact people and how we can imagine new ways to, collectively, reach peace.

He is passionate about American foreign policy and national security, and has experience working in the United States Senate, House of Representatives, and multiple think tanks in the field. Cameron is particularly interested in understanding the implications of U.S.-China competition in the Middle East, and is excited to be part of the leadership team of such an impactful fellowship. Outside of the classroom, you can find Cameron on the court as the captain of Yale Club Tennis and in the studio recording his own radio show.
