This article is part of a Huffington Post series , on the occasion of the site's 10th anniversary, looking at some of the people and issues that will shape the world in the next decade.

Annie Clark and Andrea Pino have been busy, to say the least. The two women burst onto the national scene two years ago when they filed federal complaints against the University of North Carolina at Chapel Hill for allegedly mishandling sexual assault cases and failing to provide support for survivors. The complaints, in and of themselves, were not unusual -- students have been protesting campus sexual assault policies for decades . By speaking publicly about the sexual assaults at UNC, however, Clark and Pino had a much larger goal: to change how all colleges handle cases of on-campus rape.

"We knew it was about more than UNC, and we knew it wouldn't die," Clark, 25, said in a recent interview, echoing what she told The Huffington Post in 2012: "You hear about Amherst, then it dies down. You hear about Yale, and it dies down. We're tired of it just popping up and everyone saying it's really horrible, then nothing happens."

Since 2013, Clark and Pino, who is 23, have become thorns in the side of college administrators everywhere. From their apartment in Los Angeles, they formed the group End Rape On Campus, part of a growing network of sexual assault survivors and student activists. Together, they have worked with students across the country to file complaints with the Education Department's Office for Civil Rights under the gender equity law Title IX.

Their efforts, along with those of other activists, have placed the issue of campus sexual assault squarely on the national agenda. In 2014, the White House launched a task force on college sexual assault, which President Barack Obama said was partly in response to Clark and Pino's work. Currently, 109 colleges and universities are under Title IX investigations for sexual assault, a figure that doubled in just one year. Today, students are coming forward to talk about sexual assault -- and seek justice -- in greater numbers, and with greater determination, than ever before. And social media has allowed survivors to form a community and keep the issue in the spotlight.

"Its a lot harder for this conversation to go away now," Pino said one night in April after wrapping up phone calls with sexual assault survivors at three separate universities. Although many survivors still feel "alone and silenced and blamed," she said, "it's so much easier to find people who have been through what youve been through and who are fighting back and finding strength."

This spring, the pair toured the country relentlessly in support of "The Hunting Ground ," a documentary about campus rape that features them prominently. It's hardly a victory lap, however.

"We've been back to Chapel Hill quite a few times since all of this has happened," Clark said. "It's very emotional, just because of everything that's happened here. We meet with student survivors, and know this issue is still happening. It's hard to see, but it's also hopeful that things are getting better. ... It's a process that hasn't been completely fixed."

While Clark and Pino have encouraged survivors to speak publicly about how their universities mistreated them, Alexandra Brodsky, 25, has focused on getting colleges to do right before they step out of bounds. Together with Dana Bolger, 24, an Amherst College graduate, Brodsky formed the group Know Your IX, which aims to educate students about their rights, teach them how to build campus activism and lobby federal officials on Title IX policy.

The two did not originally plan to start an organization, said Brodsky, who met Bolger through a mutual friend after filing a Title IX complaint against Yale University three years ago. But after a while, Bolger said, "it felt like there was no other choice."

"A common story we kept hearing was, 'Well, it's really great I know about Title IX now, but it would've been better if I had known about it when I needed it,'" Brodsky said.

Brodsky is now a Yale law student. When the Education Department finished its investigation of Yale in 2012, a week after she earned her bachelor's degree, Brodsky felt like federal officials had let the Ivy League school off easy . The government didn't find the school in violation of the law, and Yale was able to spin the results of the investigation as a sign they were on the right track. So in summer 2013, as Clark and Pino helped students file new complaints with the government, Brodsky and Bolger worked on a campaign called ED Act Now, pushing the Education Department to get tougher on schools.
