Emily Heyler is currently a rising junior at ‘Iolani School in Honolulu, Hawaii. Since being introduced to the world of Model United Nations a couple of years ago, Emily was immediately drawn to the competitive debates, rigorous research, and realistic diplomacy. From gaining confidence in her fear of public speaking and gaining critical thinking skills, to creating a global perspective of the world issues and fostering a passion for the world of diplomacy. Emily is honored to be a part of the delegate affairs team for YISMUN. Outside of Model United Nations, Emily can be found acting in her school’s theater program, binge watching netflix, and debating her friends on global issues.
