In addition to Frances Arnold, Maria Zuber will co-chair the President’s Council of Advisors on Science and Technology.

This will be her fourth time serving in a White House administration.

"I look forward to continuing to advocate for science and a nonpartisan manner in this new role," said Zuber, who is Massachusetts Institute of Technology’s vice president for research and E. A. Griswold professor of geophysics. "I am thrilled with the challenge and the opportunity to work together with the scientific leadership of this administration to restore trust in science and pursue breakthroughs that benefit all people."

Zuber said that the work is critical "as the pandemic continues to rage."

Beyond the pandemic, she highlighted other areas of focus for the team, including the "transition to a zero-carbon energy system, our need to create good-paying jobs of the future and other aspects of our existential fight against climate change."

Zuber grew up in Carbon County, Pennsylvania, which she described as once being coal country. Both of her grandparents mined and died of black lung, she said, while noting that communities like hers still haven't recovered long after mining jobs have left.

"I could not be more excited for the efforts of this administration to deploy science to help breathe new life into these places, into so many communities large and small that are hurting today," she said. "Bold scientific leadership will be a critical component of building back better, guarding our health and safety, helping spark new, clean industries, and keeping America competitive in the race for those well-paying jobs of the future."

Zuber was the first woman to lead a NASA spacecraft mission and the first woman to lead a science department at MIT.

In 2004, former President George W. Bush appointed her to the Presidential Commission on the Implementation of United States Space Exploration Policy. In 2013, former President Barack Obama appointed her to the National Science Board, and President Trump reappointed her in 2018.

During remarks on Saturday, Biden introduced Francis Arnold as co-chair of the President's Council of Advisors on Science and Technology and part of the first all-women team to lead the council. Arnold is the first woman in American history to receive a Nobel Prize in Chemistry and is currently the Linus Pauling professor of chemical engineering, bioengineering, and biochemistry and director of the Rosen Bioengineering Center at the California Institute of Technology. Arnold has been inducted into the National Inventors Hall of Fame.

Known for her contributions to renewable energy, Arnold co-founded three biotechnology companies in sustainable chemistry and agriculture.

"My belief has grown that our highest responsibility in each generation is to preserve our fragile planet, prepare our economy and our workforce for the future and pass on a better world," Arnold said in her remarks Saturday.

"When we put science back to work for the benefit of all people, revitalizing our economy, fueling our climate response, broadening our perspective as we rebuild around greater equity and opportunity, we are making a society that is worth passing on to our children and our grandchildren. It is an act of love. I am honored by the opportunity to help nurture this effort," Arnold said.

As deputy director for science and society for the Office of Science and Technology Policy, Alondra Nelson said she wants to promote scientific research that is "honest and inclusive."

"As a Black woman researcher, I am keenly aware of those who are missing from these rooms," Nelson said Saturday during a press briefing introducing key members of the Biden administration's science team. "I believe we have a responsibility to work together to make sure that our science and technology reflects us and when it does, that it reflects all of us. That it reflects who we are together."

Nelson, president of the Social Science Research Council and a Princeton University professor, is known for her research at the intersection of science, politics and social inequality.

"There has never been a more important moment for scientific development -- to get scientific development right or to situate that development in our values of equality, accountability, justice, and trustworthiness," Nelson said.

Eric Lander is Biden's nominee for presidential science adviser, a position Biden announced Saturday he is elevating to a Cabinet-level position for the first time in U.S. history.

Lander served as the co-chair of the President’s Council of Advisors on Science and Technology (PCAST) during the Obama-Biden administration. He currently serves as president and the founding director of the Broad Institute of MIT and Harvard. Landon is also one of the principal leaders of the Human Genome Project.

"It's not hyperbole to suggest that Dr. Lander's work has changed the course of human history. His role in helping us map the genome, pull back the curtain on human disease, allowing scientists ever since and for generations to come to explore the molecular basis for some of the most devastating illnesses affecting our world," Biden said.

In his remarks Saturday, Lander said, "The President-Elect knows that science and technology will be crucial in meeting this moment," adding that "America's greatest asset, I think, is our unrivaled diversity. After all, scientific progress is about seeing something that no one’s ever seen before. Because they bring a different lens, different experiences, different questions, different passions. No one can top America in that regard. But we have to ensure that everyone not only has a seat at the table, but a place at the lab bench."

While House Democrats take action to remove Trump from office after he encouraged supporters to march on Capitol Hill last week.

Trump on Monday plans to award the Presidential Medal of Freedom -- the nation's highest civilian honor -- to GOP Rep. Jim Jordan of Ohio, his longtime defender, in a closed event, something not the event not mentioned on his schedule, a White House official said. Later in the week, he's expected to bestow the same honor on New England Patriots head coach Bill Belichick.

Sources told ABC News over the weekend the White House is building out a week of programming to highlight Trump’s record over the dwindling days of his administration, despite amplified calls for Trump to resign or risk facing a second impeachment. Appearing to dismiss those calls, Trump has a trip planned for Tuesday to Texas to showcase the border wall he's pushed hard for, and is expected to host events in the next week to highlight what sources say are the administration's achievements in areas including foreign affairs, business and pandemic response.

The president was angry for much of this past weekend -- mostly about Twitter permanently suspending his account on Friday, according to sources who have spoken directly to Trump. Sources said the president is expected to depart Washington before Biden takes the oath of office on Jan. 20.

While Biden said last week it’s a "good thing" Trump isn’t attending his inauguration, he hasn’t said whether he supports impeaching Trump, deflecting that decision to Congress instead. Biden's said he wants the incoming Congress to focus on his Cabinet nominations and pandemic relief from the onset, but an impeachment trial in the Senate risks preempting the rest of its business.

On Monday, Biden is slated to meet with transition and economic advisors and will publicly receive the second dose of the COVID-19 vaccine from Wilmington, Delaware, in the afternoon.
