Growing up in a township full of scientists and engineers, I have always been curious about how things work. This led me to pursue a bachelor’s in engineering from Nehru Institute of Engineering and Technology affiliated with Anna University, Chennai. I then pursued a master’s from the esteemed Indian Institute of Technology, Madras where I delved into diverse research projects that captivated my interest. Fueled by this newfound interest, I started my journey as a Ph.D. student eager to tackle intriguing and fundamental challenges within the field of engineering.

I started working on my Ph.D. in the Fall of 2019 at the Computational Mechanics and Machine Learning Lab led by Dr. Susanta Ghosh at Michigan Tech. The focus of my research is on understanding the uncertainties associated with the predictions of computational and machine-learning models. Any model, computational or data-driven, is a representation of a physical phenomenon. We develop such models to understand the world around us better. However, predictions of such models are not always reliable due to the uncertainties associated with them. These uncertainties could arise for various reasons such as natural variability in the systems we study, assumptions in developing these models, numerical approximations, lack of data, etc. In order to use these models in real-life scenarios, quantifying these uncertainties is crucial. My research involves developing novel techniques to quantify the uncertainties, use these uncertainties to improve the model’s performance, and explain the reasoning behind the uncertainties. In my first project, we developed a Bayesian neural network-based machine-learning model that can reliably classify breast histopathology images into benign and malignant images. In addition, the model can quantify uncertainties associated with the predictions. We further developed techniques to explain the uncertainties and use them to further improve the model’s performance. In my second project, we developed novel loss functions for Bayesian neural networks and showed their advantages over the state-of-the-art in image classification problems. I am currently working on quantifying uncertainties in computational models that are used to characterize material behavior and extending the first two projects for several other applications.

I would like to thank my advisor Dr. Susanta Ghosh for giving me the opportunity to carry out this exciting research as well as for his immense help and guidance throughout the process. I thank the Graduate Dean Awards Advisory Panel and the dean for recommending me for this award. It is an honor. I thank the graduate school and the Department of Mechanical Engineering-Engineering Mechanics for their constant support.

I am proud to have been awarded the finishing fellowship for my Ph.D. at Michigan Technological University; my journey has shaped me into a versatile human factors specialist (human factors, in simple terms, involves bridging the gap between humans and field ‘X’ to make that field more accessible and user-friendly for humans) with expertise spanning artificial intelligence, autonomous vehicles, rail safety, and public health. Drawing on my computer science background, I have always been captivated by the advancement of powerful AI systems and their potential to become more accessible, trustworthy, and dependable for humans. My primary research focus centers around explainable artificial intelligence (XAI) and its significance in comprehending the cognitive dynamics between humans and AI in autonomous vehicles.

Beyond my dissertation on XAI and human-AI team cognition in autonomous vehicles, I have actively engaged in research within the transportation and health sectors. This active involvement has substantially enhanced my comprehension of the human factors associated with these domains.

The advent of commercially available AI systems in autonomous vehicles represents remarkable progress. However, similar to other state-of-the-art AI systems, understanding these new AI systems within the context of autonomous vehicles can pose challenges for both vehicle occupants and individuals outside the vehicle. Instead of solely concentrating on explaining ‘why’ AI systems have made specific decisions, I firmly hold the belief that providing explanations on ‘how’ AI systems ‘may behave’ in specific patterns can be more effective. By making these behavioral patterns more understandable for users and drivers, we can elevate human-AI team cognition. To address these research questions, I have adopted a mixed-method approach for my Ph. D. dissertation that combines simulated quantitative behavioral studies with cognitive task analysis methodologies.

I express my gratitude to the graduate dean awards advisory panel for selecting me as the recipient of the finishing fellowship. I am also deeply appreciative of the guidance and support provided by my mentors, Dr. Shane T. Mueller, and Dr. Elizabeth Veinott, as well as the other esteemed members of the Cognitive and Learning Sciences department at MTU. Their contributions have made Houghton feel like a second home to me. I would like to extend my gratitude to Dr. Robert Hoffman for his unwavering support throughout this journey. Finally, I would like to express my heartfelt appreciation to my wife, Dr. Lamia Alam, and my other family members for their unwavering support and understanding throughout the challenging phases of my Ph.D. journey. Their patience and encouragement have been invaluable to me.

I began my PhD journey in the spring semester of 2019, focusing on the subject of distance perception in virtual reality under the supervision of Dr. Scott Kuhl. My research investigates how people perceive distance in VR, an increasingly popular technology due to its widespread availability and recent advancements. I’ve always been interested in the Virtual Reality and Computer Graphics world since I was 12 years old.

Despite its growing popularity, numerous questions remain about how human perception interacts with virtual reality (VR). Many VR applications either require or benefit from users perceiving and interacting in virtual environments that closely resemble the real world. One of the primary challenges my research addresses is the tendency for people to underestimate distances in VR, as opposed to accurately perceiving them in real-world settings. Distances in VR are often reported as being underestimated by 20-30%, a discrepancy that is significant for many everyday tasks. These issues can lead to serious complications in various applications. For example, homebuyers using VR to virtually tour properties may struggle to accurately assess room sizes. People might also face difficulties in navigating and engaging with virtual worlds effectively. Furthermore, accurate distance perception is crucial for training and education programs involving students and even essential workers, such as astronauts. As a result, my research aims to examine how some of the procedural details might impact the results of previous VR studies regarding distance perception. One detail involves giving participants practice in blindfolded walking prior to the study to gain trust in the experimenter and experience walking while blindfolded. Additionally, to better understand this phenomenon, I have developed a program compatible with modern head-mounted displays (HMDs) that accurately tracks users’ locations and provides valuable data on participant behavior. This enables in-depth analysis of their walking behavior and perception during experiments.

I am extremely grateful to the Graduate Dean Awards Advisory Panel for granting me the finishing fellowship. I would also like to express my heartfelt thanks to my incredible advisor, Dr. Scott Kuhl, for his unwavering guidance, support, and encouragement throughout my PhD program. Finally, I extend my appreciation to the Computer Science Department and the College of Computing for their exceptional programs and the opportunities they have provided for us.

I received my Bachelor’s and Master’s degrees from the University of Toulouse Jean Jaures, in France, before joining the Rhetoric, Theory and Culture doctoral program at Michigan Tech in 2017. During the last stages of my dissertation in Fall 2022, I began working as a full-time faculty member and Writing Center manager at the New Mexico Institute of Mining and Technology near Albuquerque, NM. I am now in the midst of moving to Baltimore, MD to start a new position at Johns Hopkins University in Fall 2023.

My dissertation, “Articulating Nationalism through the “Problem of Immigration:” the Case of Foreign Unaccompanied Minors in France” examines how far-right nationalist logics and discourses permeate and articulate the system of protection of foreign unaccompanied minors in France, in the recent context of the so-called European “migrant crisis.” In-depth interviews with child welfare social workers revealed that the very structure and design of the system of protection of foreign minors, articulated through cultural and political perspectives hostile to (im)migration, compromises the protection and chances of integration of this group from the get-go. This case study illustrates national institutional responses to contemporary migration events, and explores the articulation of the question of immigration as a driving force of contemporary nationalism.

I am deeply grateful for my dissertation advisor, Dr. Patricia Sotirin, who has mentored and supported me through my PhD journey and beyond. I would also like to thank my co-advisor Dr. Jennifer Slack, whose feedback was always immensely helpful and critical to my progress, and Dr. Andy Fiss, for his endorsement and support with several professional projects. Thank you all for your support and for endorsing this nomination.

I never imagined myself reaching this point. Having given up on college in 2011, I found myself working my way through different management positions across retail. Eternal grateful for the opportunity these jobs had presented for me, they had allowed me to survive well enough. By 2016, I had found the lack of empathy, and cerebral engagement to be a bit too much. In what may have been an impulsive decision, I quit my job and returned to college. I knew I wanted to explore more of what the world had to offer, and to see how I might be able to give back.

I entered a community college and was able to secure my associate degrees by 2017. This enabled me to transfer to the University of Louisville (UofL) and begin pursuing my bachelor’s. I wasn’t certain what direction to go; and initially was determined to go for an engineering degree of some sort. In my first semester at UofL, I took a physics course with a wonderful professor; Dr. David Brown. The manner in which he approached teaching instantly drew my attention. This was what I thought education should have been my first go around. I then decided to major in Physics. That following summer, I was given my first opportunity to be a Teacher’s Assistant; And I was hooked.

I then spent the remainder of my time as an undergraduate being a Teacher’s Assistant of some form. Whether it was instructing a lab or being a resource within the classroom, I found it to be one of the most fulfilling experiences. It was through this process I learned that to teach at the collegiate I would have to go to Graduate school; This had terrified me. I had always struggled with formalized education, and certainly did not believe myself capable of the highest levels of it. I was fortunate though to have mentors to guide me. If it were not for these amazing educators, I would not be here now.

In the spirit of what they taught me, I now continue my education further. Having been accepted into Michigan Tech has been one of the proudest moments in my life. Only to be surpassed by the honor and privilege I feel to have been accepted as a KCP Fellow. With this support, I will be able to accomplish something I only had ever dreamt of as a child. In return, it is only right to give that experience back. As I complete my PhD, I hope to help cultivate a diverse culture at MTU, using my unique experiences to build our community. Afterwards, I hope to become a faculty member and work towards a more comprehensive foundational curriculum; Integrating computation, physics, and mathematics together. In my late career, I’d hope to take an administrative position to further build a more representative student body of the diversity we have in the world.
