As a professor at BYU, Peacock has had many opportunities to present lectures and to address the BYU community. In 1996 she was invited to speak at one of the university's weekly devotionals. Her address was entitled, The Searching Mind.
In spring 2010 she led a study abroad throughout Europe. The group had the opportunity to climb up the restorer's scaffolding and see the Pantocrator face-to-face at the byzantine mosaics at Daphne, Greece.
In winter 2011 her proposal to write an article for the NKJ (a Netherlands Yearbook for History of Art)was accepted. The NKJ is the top journal in the art history field. Few American scholars and even fewer feminists are published in the prominent journal.
Peacock and Professor Heather B. Jensen were curators of the 2013 BYU Museum of Art exhibit, "Rembrandt's Amsterdam." That same year, Peacock presented on "Women Artists and the Attraction of the Labadist Religion" at the Mental Health, Spirituality, and Religion in the Middle Ages and Early Modern Times conference. She was also named Honors Professor of the Year for 2013.
In 2015, Peacock received the Douglas K. Christensen Teaching and Learning Faculty Fellowship from BYU.
