What initially drew you to Embry-Riddle?
In the beginning, it was good luck! When my husband and I completed our Ph.D. studies at Florida Atlantic University, we applied to several universities across the United States. My husband was offered a position with the College of Engineering at Embry-Riddle, which brought us to Prescott. As I continued my job search, a faculty position opened in the Department of Cybersecurity—and the rest is history! After nearly four years, what keeps me here is the incredible community of students, colleagues and staff who truly make Embry-Riddle feel like family.
What are your favorite topics to teach and research?
I have been passionate about wireless communications since earning my bachelor’s degree. My master’s and Ph.D. research focused on wireless networks and communication protocols for Wireless Sensor Networks (WSNs). Now, I am applying that expertise to cybersecurity by working with Internet of Things (IoT) systems and exploring the security challenges associated with them.
What should students know about the future of the security industry?
The security industry is evolving rapidly, bringing both exciting opportunities and complex challenges. As technology advances, security professionals must continuously adapt, stay ahead of emerging threats and find innovative ways to protect data, systems and critical infrastructure. For students, this means developing a strong foundation in technical skills, maintaining ethical integrity and embracing the fast-paced nature of the field. Those who are proactive and adaptable will not only keep up but thrive in this ever-changing landscape.
What is one piece of advice you would give to today’s college students?
Strive for balance. Success in your field requires passion and dedication, but it is equally important to engage in activities that enrich your academic journey while making time for family, friends and personal well-being. Finding this balance will help you grow both professionally and personally.
What are your interests outside of Embry-Riddle?
I love to travel and immerse myself in new places, cultures and experiences, as I believe they contribute to personal growth. My husband and I also enjoy cycling together and exploring different trails—a tradition that began during our Ph.D. years in Florida when we relied on bicycles for transportation. Additionally, I enjoy watching movies, especially in theaters, where popcorn and soda complete the experience.
