A leading CRISPR-Cas9 researcher, the 14th librarian of Congress and the senior vice president at the U.S. Chamber of Commerce are among the speakers featured in The Berkeley Forum’s spring lineup, announced Sunday.

Berkeley Forum President Daniel Ahrens said this semester’s lineup will include more representation of fields such as biotechnology and information sciences, allowing students to engage with speakers on a wide range of issues.  

“I think we really did a good job of exploring issues that we maybe haven’t explored before and bringing really amazing speakers who are at the forefront of their field — fields Berkeley students might not typically hear from,” Ahrens said.

The Berkeley Forum undergoes an extensive planning process to host speaking engagements, reaching out to potential speakers via phone and email a semester in advance. Since its founding in 2012, the forum has hosted notable figures such as UC Berkeley professor Robert Reich, U.S. Secretary of Homeland Security Jeh Johnson and founder of Noah’s Bagels Noah Alper.

Berkeley forum events, as they grow in popularity, are attended by many students, although some engagements in the past have featured speakers raising controversy. Events featuring figures such as Johnson and UC Berkeley Chancellor Nicholas Dirks drew student protesters in 2015.

According to Ahrens, the 2016 presidential election played a moderate role in furthering the forum’s mission to feature speakers on campus who encourage students to see opposing perspectives on an issue.

“Obviously, with a contentious election, the Berkeley Forum is a nonpartisan organization and we’re always interested in how we can create dialogue on opposing sides of an issue,” Ahrens said. “So (the election) reinvigorated our mission to push for dialogue on both sides that disagree.”

Of the figures listed in this semester’s lineup, Ahrens said he is most looking forward to hosting 14th Librarian of Congress Carla Haden and Twitch.tv founder Justin Kan.

“I’m just excited to have the opportunity to break ground on a lot of these issues and bring them to the student body — and (that) these speakers have the opportunity to engage with students and students have the opportunity to engage with them,” Ahrens said.
