UC computer science engineer works to improve AI explainability

Nkechi Jennifer Akinwale named Graduate Student Engineer of the Month

Inspired by the desire to improve and advance the world of artificial intelligence, Nkechi Jennifer Akinwale has taken advantage of every available opportunity at the University of Cincinnati.

Along with a dedication to her field, Akinwale has a deep-rooted dedication to the mentorship of young girls in STEM. She has mentored numerous undergraduate and K-12 students in various programs to share her knowledge and experience as a doctoral student. Recently, she was named Graduate Student Engineer of the Month by the College of Engineering and Applied Science. 

Why did you choose UC?

I have always wanted to research the areas of databases and machine learning within computer science. When I was applying for graduate programs, the University of Cincinnati stood out to me due to its status as an R1 research institution and its cutting-edge initiatives, strong academic programs, renowned faculty, vibrant campus communities and campus resources. I was also interested in the research of Seokki Lee, assistant professor of computer science. His work centers on databases, data provenance, and machine learning, or ML, which perfectly aligns with my interests. These factors made UC the ideal choice for my graduate journey.

Since elementary school, math and science have always been my strongest subjects. While pursuing an associate degree, my passion for computer science was ignited. I took a liking to its blend of mathematics and abstract thinking. After that, I went on to pursue a bachelor's degree in computer science, graduating with first-class honors, and was recognized as the best graduating student in the computer science department at the University of Ibadan, Nigeria. Following my graduation, I went into the industry working for companies in fintech and banking, where my interest in databases and machine learning grew, and I felt I could make more impact in research. I am driven by diverse opportunities in the field and the desire to contribute to the development of new and innovative technologies. In pursuit of my goal, I have since earned a Master of Engineering Degree in computer science from UC and am on track to earn my doctorate in computer science and engineering. 

Describe your research work. What problems do you hope to solve?

My research focuses on developing explainable ML models using data provenance, or data lineage. Many industries and sectors rely heavily on ML and AI algorithms for data-driven decision-making, which enhances operational efficiency. However, there is often a general mistrust of their predictions and outputs, primarily due to their lack of explainability as black-box algorithms (algorithms that do not allow users to see the logic that produced the output). For example, consider a scenario where an AI model predicts that a credit card applicant will default on payments and denies their credit application, but does not give clear insights as to why. Or, imagine a situation wherein a facial recognition algorithm produces erroneous outputs leading to unjust accusations or arrests. To address this challenge and build trust in ML predictions and outputs, explainability is crucial. 

Through my research work, I am committed to developing provenance-based explainable solutions that enhance ML explainability, mitigate biases, and increase adoption of this technology. My objective is to advance ML explainability by leveraging data provenance to provide human-understandable explanations for ML predictions and outputs. This interdisciplinary research combines databases, data provenance, and ML within the Database Group at UC led by Dr. Seokki Lee. 

I aim to bridge the gap between the technical complexities of AI/ML and users with diverse expertise, ensuring transparency and trustworthiness in ML applications. 

What are some of the most impactful experiences during your time at UC?

I have published and presented my work at prestigious scientific and engineering conferences and workshops. I have attended 14 conferences, delivered one oral presentation, presented three posters, and spoken at two panel discussions. 

These opportunities have been invaluable for engaging with the scientific community and establishing meaningful connections with professionals and researchers across various disciplines. They have also kept me at the forefront of advancements in the field and helped me identify opportunities for further research and scholarly contributions. Additionally, these experiences have taken me to various major cities across the U.S. 

In terms of leadership and mentorship at UC, I have held several impactful roles. I serve as the president of the Electrical Engineering and Computer Science Graduate Student Association and previously served as the treasurer. I served as the graduate student affairs officer for UC's chapter of the Society of Women Engineers. I'm also in the professional development committee of the Graduate Student Government where we've pioneered professional development opportunities for graduate students. 

I am grateful for the guidance of my advisers and mentors, whose support has been invaluable in my journey. Being able to mentor others and contribute to their growth has been a rewarding aspect of my time at UC. 

What are a few of your accomplishments of which you are most proud?

The personal and professional growth I have experienced during my time at UC has been remarkable. One achievement I'm proud of is my research project on developing provenance-based solutions for explainable machine learning models. I have presented this work at prestigious conferences like the Institute of Electrical and Electronics Engineers International Conference on Data Engineering, American Association for the Advancement of Science Annual Meeting, and the Greater Chicago Area Systems Research Workshop.

In addition, I have had the honor of contributing to the scholarly community by serving as a program committee member and a reviewer on the research paper track for various conferences. 

I take great pride in my contributions to professional organizations in science and engineering such as the Institute of Electrical and Electronics Engineers. Currently, I am serving a two-year leadership commitment on the Society of Women Engineers' national organization and was honored to speak at two panel sessions dedicated to advancing graduate engineering at the 2023 conference. 

Equally fulfilling has been my role in nurturing the next generation of scientists and engineers. I served as a mentor for the UC McNair Scholars, the Society of Women Engineers' "Invent It, Build It" program for K-12 students, and as a judge at events such as the Ohio Academy of Science District Science Day and State Science Day. I was also a counselor at various CEAS summer camps and a professional reviewer of research posters at the 2023 UC Undergraduate Scholarly Showcase. 

Reflecting on my journey, I am grateful for the consistency and excellence that have marked my experience. Earning my master's degree in 2023 from UC was a significant milestone towards completing my doctorate. I am also honored by the accolades I have received, including being named Graduate Student Engineer of the Month, and receiving the 2023 Cadence Diversity in Technology Scholarship Award. 

When do you expect to graduate? What are your plans after earning your degree?

I plan to defend my PhD dissertation by spring 2026. After completing my PhD, I will pursue a career in research or industry, specializing in developing optimized, large-scale unbiased data provenance systems and ML solutions. My objective is to contribute to pioneering scientific advancements, ideally in an academic or high-tech industry environment.
