School of Science, Technology and Health

Dr. Sarah Templeton, Ph.D. 

Associate Professor of Nursing, Associate Director of Nursing

Dr. Sarah Templeton’s ('99) love for Biola began during her undergraduate education in the nursing department. She has spent the majority of her 23-year nursing career serving as a registered nurse, then a nurse practitioner, and over the last five years as the director of the on-campus Student Health Center. Her significant university contributions include providing leadership and direction through the COVID-19 pandemic, infusing proactive and preventative mental health services within the Student Health Center, and improving access to high-quality on-campus healthcare for students. Templeton has also served as an adjunct faculty member for the nursing department for approximately 15 years teaching a variety of courses. The opportunity to teach and mentor nursing students has been a highlight in her career. Templeton always believed she would conclude her nursing career as a full-time nursing professor at Biola University. In August 2023, Templeton will continue her work in serving future nurses as a full-time professor and associate director in Biola's Department of Nursing. She is eager to continue preparing the next generation of nurses, stepping into new leadership opportunities and contributing further to nursing research.

“When patients are in need of a nurse it is often when they are most vulnerable and in need of care beyond what one can provide for himself/herself. These strangers, the nurse and the patient become deeply and quickly connected,” said Templeton. “Often very personal information is shared, intimate or difficult conversations occur, and sensitive care is provided. Similarly, there is an extraordinary amount of trust patients give to their nurses — to accurately provide medications within safe parameters, to provide precise medical treatment and education, and to ethically act on behalf of the patient. A Christian nurse is an ideal candidate to fulfill this role! Biola's nursing program is exemplary in training excellent nurses to ethically and precisely meet patient needs, while reflecting Jesus, the Great Physician, as clearly as possible. Christian education prepares the nursing student to effectively minister to the whole person through the provision of excellent physical, emotional and spiritual care.”

Melissa Raymond, M.S.

Communication Sciences and Disorders

Clinical Coordinator

Melissa Raymond graduated with a Bachelor of Arts in Integrated Educational Studies and a Master of Science in Communication Sciences and Disorders from Chapman University. Raymond joined Biola in 2021 as a clinical coordinator organizing students’ clinical externship placements and initiating and maintaining clinical affiliations between Biola and our community. Coming from PIH Health Hospital and Saddleback Memorial Medical Center, Raymond developed her administrative skills and later as a medical speech language pathologist. Raymond brings experience in both her non-clinical administrative role, where she utilized valuable skills in organization, project management and teamwork, coupled with her transition into a clinical role as a medical speech-language pathologist where she focused on patients in acute care and outpatient rehabilitation settings with swallowing and communication abilities after various medical diagnoses and neurological injuries. In addition, Raymond also provides home health services demonstrating her commitment to providing individualized care to address patient goals in a functional context. She has a desire to be a source of "salt and light" in the field of speech-language pathology. She is dedicated to not only the technical aspects of her profession but also the deep-rooted values that guide her work to influence future generations of therapists to serve God through this profession.

“By embodying the principles of Christ's teachings — compassion, humility and service,” said Raymond. “We endeavor to show and spread God’s love to those entrusted to our care, striving to show grace amidst difficult healthcare challenges, reminded that He gave it to us first.”

Jessica Olsen, M.S. 

Communication Sciences and Disorders

Jessica Olsen ('08) is a speech-language pathologist from Southern California. She attended Biola University for her undergraduate degree in communication disorders and received her Master of Science in Communication Sciences and Disorders from Chapman University. Upon graduation, she worked with adults in acute/ICU settings, working with a team following patients with brain injury from admission until discharge. She later switched to working with children, supporting classrooms for children on the autism spectrum who demonstrated severe maladaptive behaviors and gained her natural language acquisition certification. Olsen has been an adjunct faculty member at Chapman University’s graduate program since 2018 and began as an adjunct professor with Biola in 2022. Currently, she is completing her Ph.D. in health sciences and focusing on neurological rehabilitation and health professions education.

“Jesus said, ‘By this all people will know that you are my disciples, if you have love for one another.’” (John 13:35). Being a speech-language pathologist (SLP) allows the Christ-followers in our field to love our clients intentionally and offer hope in trying times, walking alongside them, and caring for them with the guidance of the Holy Spirit,” said Olsen. “With a strong Christian foundation integrated into the coursework and comprehensive methodologies based on the latest research, future SLPs can implement relevant evidence-based practices and incorporate these elements to improve client outcomes. Demonstrating a loving and caring attitude when our clients are in need of our services can bring light into their world through Christ, where they had only seen despair or darkness.”

Dr. Ileana Callejas, Ph.D. 

Biological Sciences

Dr. Ileana Callejas earned her Doctor of Philosophy in Environmental Engineering from UCLA, where she also obtained her Master of Science in Environmental and Water Resources Engineering and her Bachelor of Science in Environmental Science with a minor in environmental engineering. Before joining Biola, she taught introductory microbiology laboratory courses at Mount Saint Mary’s University. Her research focuses on studying the fate and transport of antibiotic resistance in rivers and beaches. Additionally, she uses satellite remote sensing for coastal water quality monitoring, particularly in Belize. In this capacity, she has collaborated with institutions such as the NASA Jet Propulsion Laboratory, Belize Coastal Zone Management Authority & Institute, and the Belize Wildlife Conservation Society. Passionate about education, Callejas is committed to integrating authentic research experiences and evidence-based approaches into her classroom. As a first-generation Latina, born and raised in Los Angeles, California, she hopes to inspire her students to harness their skills and knowledge in the stewardship of the environment and in service to others, all for the glory of God.

“Issues surrounding climate and the environment rank among today's most pressing and contentious concerns,” said Callejas. “As Christians, we recognize the profound value of both humanity and God's creation. It is imperative for believers to integrate their knowledge, faith and ethics to address environmental challenges, especially as they disproportionately impact "the least of these” (Matt. 25:40) — our most vulnerable populations. Christian higher education equips students not only with academic understanding but also with a Christ-centered perspective. This foundation encourages the development of holistic and sustainable solutions, driven by our deep reverence for the Creator and His creation.”

Dr. Wonjun Lee, Ph.D.

Math and Computer Science

Dr. Lee's research focuses on designing AI-based defense systems. His work is aimed at securing container-based cloud computing systems working toward creating knowledge-based immune systems inspired by human immunology. His research examines highly scalable and autonomously responding system-security approaches using different AI models to protect microservice architecture applications. Lee achieved his Doctor of Philosophy in Electrical and Computer Engineering from Purdue University in 2011 and has worked for Samsung and several universities as a cybersecurity researcher and teacher. Additionally, he is playing as a wing forward in a regional soccer team and serving as a guitarist in a small community church.

“We are living in the world of postmodernism under the impact of pluralism. Our war fighting against the secular world is to confront an intellectual mindset that refuses the absolute truth,” said Lee. “I think a Christian worldview formed through Christian higher education is the most exciting and innovative framework because it is based on the Word of God, who will radically change this distorted world and create a new world. Christian higher education provides a fertile soil to students so that they can have a rigid, unshakeable root in Christ, to seek God's Kingdom.”

Dr. Elaine Kojima Chiu, OTD 

Occupational Therapy

Dr. Elaine Kojima Chiu has enjoyed her work as an occupational therapist (OT) for over 23 years in clinical, school-based and academic settings. Before entering the allied health field, she earned her bachelor’s degree in studio art at the University of California, Irvine. Following graduation, she was involved with the Japanese Evangelical Missionary Society’s Special Camp. Serving alongside adults and children with neuro-diverse backgrounds inspired her to change career directions to become an OT. Kojima Chiu went on to earn both her master’s and clinical doctorate degrees in occupational therapy at the University of Southern California. As a clinic and school-based therapist specializing in sensory integration and adolescent to adult transitions, she has had the opportunity to work with children with different physical and developmental disabilities such as autism spectrum disorder, cerebral palsy, Down syndrome, etc. She also taught adolescent and pediatric intervention courses and worked as clinical fieldwork faculty at California State University Dominguez Hills' OT Department. Currently, Kojima Chiu is committed to helping develop the academic curriculum and fieldwork program for the new Master of Science in Occupational Therapy (MSOT) program at Biola University.

“Christian higher education is vitally important for equipping and mentoring the next generation of souls to live and work in the community with Christ-centered values and a biblical worldview,” said Kojima Chiu. “In the field of occupational therapy, having a godly perspective on life is essential when providing and extending genuine love and compassionate care to the individuals we work with. ‘We love for He first loved us.’ (1 John 4:19) OT students who graduate from Christian universities will go on to be ambassadors for Christ in whatever area of practice God places them. My prayer for the future Biola MSOT graduates is that they will be steadfast reflections of Jesus not just in their work, but in all aspects of their lives.”

Deborah Hoffman-McCully, M.S. 

Assistant Professor in Nursing

Deborah Hoffman-McCully went back to school with a focus on nursing a year after her son passed away. A wonderful nurse inspired her, and she knew God wanted her to pursue this type of career in memory of her son. She began her nursing career in 1996 and then focused her nursing specialty in the maternal newborn department in 2000. She worked in this field for St. Jude Hospital for 23 years when God called her to shift her nursing path to Biola University. She enjoys crafting, painting and spending time with her husband and their labradoodle, “Tucker.”

"The significance of Christian higher education and a strong Christian foundation in the field of nursing is multifaceted. Integrating Christian values and principles into nursing education can profoundly impact both the quality of care provided and the patient's overall well-being,” said Hoffman-McCully. “A Christian foundation encourages compassion and empathy, essential traits for nurses. The teachings of love, kindness and service that are central to Christianity can inspire nurses to approach their patients with genuine care and understanding. Christian higher education emphasizes the importance of treating each person as an individual, regardless of their background, beliefs or circumstances. This inclusivity and respect for diversity can enhance cultural competence in nursing, enabling nurses to provide holistic care that respects patients’ unique identities and needs. This holistic approach benefits not only patients but also the nurses themselves, contributing to a more fulfilling and impactful nursing career.”
