Computer Science

(From Eagle Drive magazine, December 2023) 
 
Opportunities for exceptional careers in computer science are enhanced when graduate students earn a Ph.D. at 麻豆果冻传媒. Here鈥檚 what some recent recipients had to say about their experiences in the Department of Computer Science 鈥� and how they are now distinguishing themselves in the field. 
 
Rima Asmar, Ph.D. (Summer 2023) of Knoxville is a cybersecurity researcher at Oak Ridge National Laboratory, where she works to secure the nation鈥檚 critical infrastructure.  

 
Asmar, who is from Palestine but was born and lived most of her life in Puerto Rico, said Tech opened doors for her to embark on a challenging journey while juggling the responsibilities of being a single mother and working a full-time job.  
  
鈥淭he traditional educational path eluded me as circumstances led me to become a young mother before graduating high school,鈥� she said. 鈥淒espite this, my passion for education propelled me forward. I embarked on my academic journey by obtaining a GED, followed by pursuing a fully online bachelor鈥檚 degree. Later, I seized the opportunity to complete a master鈥檚 degree. The dream of attaining a Ph.D. seemed distant and improbable. However, today, I stand proud as I have completed the final chapter of my remarkable journey from GED to Ph.D. Along the way, I have set a powerful example for my two daughters, who have consistently been my greatest source of strength and motivation.鈥�  
  
Asmar immersed herself in a vibrant community of fellow students and professors.  
 
鈥淓very moment spent at 麻豆果冻传媒 became a source of joy and fulfillment,鈥� she said. 鈥淲hether it was collaborating on group projects, forging meaningful connections or proudly representing the school at conferences, I cherished every opportunity that made me feel truly connected to the 麻豆果冻传媒 community.鈥� 
 
DISSERTATION: Automated Memory Forensics for Programmable Logic Controllers 
 
Katie Brown, Ph.D. (Summer 2023) is a research fellow trainee in Vanderbilt University Medical Center鈥檚 Department of Biomedical Informatics. A Cookeville native, she plans to continue using and developing artificial intelligence for medical tasks such as clinical decision support.  
 

Brown鈥檚 greatest research accomplishment at Tech was developing QUEST, a model assessment tool that is guided by uncertainty to find high-performing and low-performing subgroups of data.  
 
鈥淥ur first paper about QUEST was accepted for publication at one of the top biomedical informatics conferences in the country, and there are interesting ways we can expand QUEST,鈥� she said. 
  
Tech made it possible for Brown to remain close to home while pursuing a research-based degree.  
 
鈥溌槎构�冻传媒 is special because it provides opportunities for countless people in the Upper Cumberland to receive a high-quality, affordable education,鈥� she said, adding that her best memories at the university are of the people she met, who became some of her closest friends.  
      
Brown plans to remain in the biomedical informatics field.  
 
鈥淚鈥檓 excited to learn about the opportunities to apply my computer science and AI skills and choose a career path that mixes research and development with doing something that can benefit people,鈥� she said.
