New Faculty

Deerfield Academy is proud to announce our newest faculty joining us for the 2020-2021 school year. From an acclaimed artist and educator whose work can be seen at MoMA, to experts on Afrofuturist writings and the oeuvre of Stephen King, an abstract algebraist, and Japanese cinema—these individuals will inspire students in their myriad studies.

Angel Abreu ’92 is thrilled to return to Deerfield as the Wallace Wilson Fellow. Angel is an artist, writer, and educator who studied philosophy, art history, and comparative literature at the University of Pennsylvania and New York University. Angel’s work resides in over 120 permanent museum collections around the world, including the Museum of Modern Art (MoMA), the Philadelphia Museum of Art, and Tate Modern. While still a student at Deerfield, and in collaboration with the art collective Tim Rollins and K.O.S., Angel became the youngest individual to have a work acquired by and be listed on the artists’ roster of MoMA. The collective has reinvented itself and become Studio K.O.S. under Angel’s leadership. In 2019, Studio K.O.S. had its first commercial exhibition since Rollins’ passing at Lehmann Maupin Gallery in NYC. They have continued to conduct socially engaged workshops with youth and educators around the country. Angel and Studio K.O.S. are the 2020 honorees of Art Resources Transfer (A.R.T.). In addition to his work with Studio K.O.S., Angel continues his own painting practice based on literature, music, and social practice in his Hoboken, NJ studio. Angel is on faculty in both the BFA Fine Arts and MFA Art Practice departments of the School of Visual Arts in New York City. He also serves on the Education Committee of The Bronx Museum of the Arts.

Shastri Akella earned a PhD in Comparative Literature at the University of Massachusetts Amherst, where he previously earned a MFA in Creative Writing. In 2016, he received the student-nominated Distinguished Teaching Award, which is conferred to only two of the nearly 900 teaching assistants working on the Amherst campus. His teaching expertise includes climate fiction, creative writing, horror, Anglophone literature, and migration studies. His fiction and essays have been published in Guernica, Electric Literature, World Literature Today, The Rumpus, The Common, PANK, and Danse Macabre. His academic writing includes essays in Childhren and Childhood in the Works of Stephen King, the Journal of Supernatural Studies, and Making Strangers: Outsiders, Aliens, and Foreigners. He previously worked as a manager at the India, Dublin, and San Francisco offices of Google. He was part of a street theater troupe in India, and at the university he led a group of students in the study of shows at the Fringe theater festival. 

Yoel Castillo Botello holds a PhD/MS in Spanish Literature and Cultural Studies from Georgetown University. Previous teaching appointments include Grinnell College, Wabash College, the Pontifical Xavierian University in Bogotá, and Georgetown University, where he also served as the Assistant Director for the School of Foreign Service Spanish Program. Yoel’s research interests in performance, book studies, and the digital humanities have been a great source of inspiration for his teaching practice. He believes that students tend to learn better in environments where they can make use of their unique interests, nurture their talents, and fully express themselves. Besides his primary passion of teaching Spanish language and literature, Yoel enjoys the performing arts and, in previous years, has been a member of a classical Spanish theater troupe and danced with flamenco ensembles in Spain, Colombia, and the United States. He is a native of Eastern Cuba. 

Jordan is excited to join Deerfield’s faculty after having lived in the Freshman Village on campus with his wife Heather for the past three years. He grew up in North Carolina and graduated from North Carolina State with a BS in Parks, Recreation, and Tourism Management with a concentration in Program Management. Throughout his career, Jordan has designed, developed, and managed a variety of student programs, including traditional camps, adventure recreation, and educational travel programs. Most recently he has served as the Caribbean Director for Broadreach’s live-aboard sailing and scuba trips, and helped to develop Explorica’s outside sales initiative for New England teachers looking to travel abroad with their students. Jordan is a volunteer firefighter for Deerfield, enjoys hanging out with his dog Hatch, riding motorcycles, and traveling. 

After growing up in NC, Aidan attended Carleton College in Northfield, MN. While there, he studied computer science and Japanese. He was involved in the Carleton athletics program, captaining the men’s volleyball club, assisting with the women’s varsity volleyball team, and working as an assistant athletic trainer.

After graduation, he worked as a systems and business analyst at TransEnterix, a medical robotics company. While so employed, he also coached boys and girls volleyball at North Carolina Volleyball Academy. In his spare time, Aidan enjoys playing computer and board games, rock climbing, and playing Frisbee golf. 

Lara Du fell in love with the beautiful, magical subject of mathematics during her high school years. Because she initially struggled in her math classes, she sought out math puzzles for extra practice. By the summer of her junior year, she was completely hooked. Lara went on to major in math at University College London before coming to the US to do her PhD in Number Theory at the University of Michigan. She has been teaching math to a variety of teenage audiences since 2014, creating and implementing her own curriculums since 2017. Inside her interactive classroom, Lara works on developing students’ confidence in tandem with their mathematical knowledge. She strongly believes that math is for everyone, and a part of her work that she enjoys the most is mentoring non-stereotypical young mathematicians. Outside the classroom, Lara enjoys cooking, singing karaoke, and playing board games with her students, as well as solitary meditation, crossword puzzles, and long walks. 

Arianne Evans ’16 is a recent Class of 2020 graduate from Bucknell University’s Freeman College of Management with a BSBA in Managing for Sustainability. While at Bucknell, Arianne played on the University’s Division 1 women’s water polo team, led excursions with the Outdoor Education and Leadership program, served as a Teaching Assistant and Freeman Fellow for the College of Management, and worked as a residential advisor in the senior apartments. In her most recent position as Senior Class President, Arianne collaborated with the Facilities department, the Bucknell Farm, and Outdoor Education to design and implement their senior class tribute project, building a fire pit constructed out of recycled materials at the campus farm. One of her favorite projects at Bucknell was starting a residential community for women’s leadership and empowerment called “Sunnyside,” which is now an official housing option. In her free time, you can find her jumping in any and all bodies of water, watching documentaries, or laughing on the phone with her mom and two sisters. Arianne is thrilled to return to the Valley as a Teaching Assistant and all-around campus support system for the Big Green! 

After spending the last seven years in the Mississippi Delta working as the town planner for Wilson, AR, serving as founding trustee and interim head of the Delta School, as well as overseeing the construction of the new Hampson Museum for Native American art, John returns to his teaching roots in New England. As a visual arts instructor at Andover and Choate Rosemary Hall, he lived in a dorm and coached ice hockey and cycling. John has a BA in fine arts with a minor in art history from Stetson University and a MAE from Rhode Island School of Design, with a focus in photography (pardon the pun). Aside from teaching, John is passionate about mechanical design, including building and flying airplanes, and restoring vintage German automobiles. John recently facilitated the design and construction of a solar array to power the Delta School. He will be the sabbatical replacement for Tim Trelease during the 2020-2021 school year. 

Hardy is very excited to join Deerfield’s faculty. He has been teaching in boarding schools for sixteen years, first at St. Andrew’s School, then Lawrenceville School, and most recently at Western Reserve Academy, where he was the chair of the Math Department. He chose a life in boarding schools, and Deerfield in particular, because he enjoys immersing himself among his students, empowering them to lead their communities, and helping them face all manner of challenges in their lives. A graduate of Duke University with majors in English and Mathematics, Mr. Gieske also holds an MFA in Fiction Writing, and took a gap year aboard a sailboat. He lives on campus with his wife (Vanessa), two children (Dash and Junie), dog (Fergus), and cat (Peggy Sue). 

Bill joined Deerfield Academy in the fall of 2020. Prior to Deerfield, he taught at a private college preparatory school in Kansas City, MS for seventeen years. His affinity for teaching fills him with gratitude for the time he shares with his students. In his career, Bill has experience teaching a wide range of courses in mathematics, coaching football and basketball, and mentoring students. He believes abstract thought is the key to personal enlightenment and a path to becoming a better person, and he considers learning mathematics one of the best ways to develop critical and abstract reasoning skills. He admires the subtleties and beauty contained in mathematics and strives to engage his students to develop their own appreciation for the subject. Bill and his wife Charlotte grew up outside of Chicago. They like to spend their free time traveling, seeking out new experiences, and exploring culture through food, arts, and entertainment. Bill also enjoys working with his hands, playing board games with friends, and engaging in philosophical discussions. Bill and Charlotte are excited to explore their new home in Massachusetts and become engaged members in the community. 

Emma graduated from the University of Sheffield in 2009 with a dual Bachelor’s degree in French and English Literature. To continue following her passion for both of these subjects, immediately after graduation she moved to Bordeaux, France, where she stayed for four years. During this time, she taught English at the Université Montaigne, the institution from which she also earned her master’s degree in literature. Before moving to Deerfield, Emma taught English at the Pembroke Hill School in Kansas City, MO. Emma coaches cross country and basketball, and is thrilled to be in New England, which reminds her an awful lot of where she grew up in old England. 

Since his teenage years, much of Bowen’s educational and professional trajectory (as well as travel) has centered on the African Continent. Following his graduation from Choate Rosemary Hall and UNC-Chapel Hill (majoring in African Studies and French), Bowen worked for a study abroad program in Cape Town and a college access organization in his home state of North Carolina before earning a Fellowship at African Leadership Academy in Johannesburg, South Africa. After serving in a college counseling capacity for one year, Bowen transitioned into a teaching role at ALA, and for five years actively contributed to the Academy’s signature African Studies Department. During his tenure as Humanities faculty at ALA, Bowen developed electives entitled “The African Diaspora” and “Africa Through the Lens,” created mini-units with titles as diverse as “Who is an African?” and “Afrofuturism and the African Renaissance,” facilitated a series of PD workshops for international educators seeking to ethically incorporate African Studies content into secondary school curricula, and conducted curriculum-building research in the American South and Senegal. At Deerfield, Bowen is excited to learn from his colleagues in the History & Social Science department, to explore African and Latin American history comparatively, and to facilitate immersive discussion and media-heavy learning experiences for his students.

Kiyo comes to Deerfield after completing his Fulbright grant in South Korea, where he taught English to middle and high school students for a year. A product of a boarding school education himself, Kiyo is excited to join the Deerfield faculty and re-immerse himself into the rigor of boarding school life. He earned a BA in History and Education at Brown University, and he wrote a senior thesis that explored the intricacies of postwar memory, as seen through recent Japanese films on the special-attack pilots. Born in Japan and raised in Japan and the United States, Kiyo created a document that facilitates Japanese immigrants’ transition to the Rhode Island education system. In his free time, Kiyo enjoys watching baseball and listening to various genres of music. As a Penn Fellow, Kiyo is working toward earning a Master’s degree from the University of Pennsylvania.
