“My unexpected doctoral journey at Michigan Technological University began in June 2022, when I transferred from New York to continue my research under the guidance of Dr. Steve Voelker. This transition was driven by my commitment to an ambitious project I began a year earlier, focused on reconstructing climate variability in the Lake Superior region and understanding large-scale atmospheric circulation patterns across North America.

Over the past four years, my research has taken me to numerous lakes and creeks throughout Michigan’s Upper Peninsula, where, with the support of Dr. Voelker and a dedicated team of undergraduate and graduate students, we have collected thousands of submerged white pine samples preserved underwater for centuries.

Following previous evidence suggesting that white pines growing in specific locations across this region could be highly sensitive to climate, our project aims to determine whether carbon and oxygen stable isotopes in annual growth rings of white pine trees can be used to reliably reconstruct both winter climate conditions along the southern shores of Lake Superior and atmospheric circulation patterns across North America over the past 500 years.

The data we have collected have also enabled us to investigate the effect of Lake Superior on local and regional climate, and how this translates into tree stable isotope variability both spatially and among species. Beyond reconstructing climate, our data have enabled analyses of white pine long-term population dynamics, shedding light on the drivers of white pine fluctuations over centuries.

This research has been made possible through Dr. Steve Voelker’s vision and successful securing of NSF funding, critical financial support from the College of Forest Resources and Environmental Science, and Michigan Tech’s Finishing Fellowship, which will support the completion of my dissertation during the Fall 2025 semester.”

“I began my Ph.D. in the Rhetoric, Theory and Culture program in the Humanities Department in 2021. With a deep interest in understanding how emerging media technologies shape different aspects of human communication, my research has largely centered on the intersection of new media technologies, digital communication and collective action.

My dissertation explores the role of social media algorithms in collective action, with a particular focus on how they shape the structure, visibility and effectiveness of digital activism networks. Using #FixTheCountry in Ghana and #EndSARS in Nigeria as case studies, I investigate the relationship between the organizing strategies of activists (both online and offline) and the affordances and constraints of Twitter (now X). I use computational social network analysis and in-depth interviews to examine activists’ awareness of the platform and network effects, and to explore whether algorithmic folk theories and/or obfuscation techniques play a role in how they use social media for collective action.

During my time at Michigan Tech, I have presented my work at international conferences, including the International Communication Association (ICA) in Canada and Australia, and taught courses in Professional and Technical Communication and Composition. Together, these experiences have been integral to my Ph.D. journey and deepened my engagement with the field of communication. In Fall 2024, I received the Dean’s Outstanding Graduate Teaching Award.

I am incredibly honored to receive the Doctoral Finishing Fellowship from the Graduate School. I truly appreciate the recognition from the Graduate Dean Awards Advisory Panel and the dean, and I’m especially grateful to the donors whose generosity makes this support possible. I would also like to express my sincere appreciation to my advisor, Dr. Sarah Bell, for her support, and to my committee members, Dr. Stefka Hristova, Dr. Richard Canevez, and Dr. Brooke Foucault Welles, for their guidance. I’m also thankful to all the faculty in the Humanities Department for their encouragement throughout this journey.”

“I am deeply honored and humbled to have been awarded the Doctoral Finishing Fellowship at Michigan Technological University. My heartfelt thanks go to the Graduate School and the Graduate Dean Awards Advisory Panel for recognizing my research and supporting me at this stage of my journey. First and foremost, I am profoundly grateful to my advisor, Dr. Christo Z. Christov, for taking me under his guidance and for his unwavering support throughout my PhD. His mentorship has been invaluable in shaping both my research and personal growth as a scientist.

Before joining MTU, I completed my B.S. in Chemistry at The New College, Chennai, India, and my M.S. in Chemistry at Vellore Institute of Technology, Vellore, India. In Spring 2021, I began my PhD research in the Department of Chemistry at MTU, focusing on the computational exploration of catalytic mechanisms of non-heme Fe(II)/2-oxoglutarate enzymes.

My research aims to understand the factors that influence enzyme reactivity and the bifurcation of catalytic pathways – insights that can inform experimental efforts in drug design and enzyme engineering. To this effect, I have employed a variety of computational chemistry techniques, including Molecular Dynamics (MD), Quantum Mechanics (QM), and hybrid Quantum Mechanics/Molecular Mechanics (QM/MM) approaches, to probe the structure-function relationships in enzyme catalysis.

During my Ph.D., I contributed to two significant projects. The first was an NSF-funded project on the Ethylene Forming Enzyme (EFE), where my research uncovered a second branch point in the catalytic mechanism of EFE using MD and QM/MM techniques. The second project was an NIH-funded investigation into Histone Demethylases (KDMs). In this project, I examined the distinct catalytic activity of the KDM6 family of enzymes, particularly focusing on the catalysis of different alkylated substrates by KDM6B. These findings have the potential to guide the design of novel peptide therapeutics.

I am eager to continue building upon these discoveries and to further contribute to the field of computational biochemistry. The knowledge, skills, and insights I have acquired during my PhD, from mastering advanced computational techniques such as MD, QM, and QM/MM, to elucidating intricate enzyme mechanisms, have provided me with a foundation to address challenging problems at the intersection of chemistry and biology. This experience has not only deepened my knowledge of enzyme catalysis but has also honed my capacity to design and interpret computational experiments that can guide and complement experimental efforts.

I am confident that the expertise I have cultivated at MTU will be instrumental in my future research career, enabling me to pursue impactful work in drug discovery, enzyme engineering, and beyond. I eagerly anticipate utilizing this foundation to explore novel questions, collaborate across disciplines, and make meaningful contributions to advancing science.
Once again, I extend my sincere gratitude to the Graduate School, the advisory panel, and all who have provided me with support throughout this journey. I eagerly anticipate the next chapter in my career, driven by the curiosity and passion that have propelled me thus far.”

“I’ve always been passionate about renewable energy and its potential to transform our world, particularly in challenging environments like snowy northern climates. My journey at Michigan Tech began with earning my Master’s degree in 2019, followed by starting my PhD in Mechanical Engineering in Fall 2021. My doctoral research focuses on optimizing single-axis solar trackers to enhance solar energy efficiency and resilience against snow accumulation. Specifically, my work involves developing innovative methods to accurately estimate and mitigate snow-induced energy losses, which is critical for improving the reliability and efficiency of solar power installations in northern latitudes. My dissertation research has led to an application for a patent focused on a smart control algorithm designed for snow mitigation, which holds significant potential benefits for the solar energy industry.

Throughout my time at Michigan Tech, I’ve been fortunate to engage in practical projects, including hybrid microgrids and life-cycle assessments. Representing Michigan Tech at international forums such as the United Nations COP for three consecutive years has provided me with a global perspective and reinforced my commitment to sustainable energy solutions. Additionally, obtaining a graduate certification in sustainability and resilience has significantly shaped my approach to addressing engineering challenges.

I’m deeply thankful to my advisor, Dr. Ana Dyreson, for her invaluable mentorship and continuous support. I also extend my gratitude to the Graduate School, the Mechanical Engineering Department, and the Dean’s Advisory Panel for awarding me the Finishing Fellowship, which has allowed me the dedicated time to complete my dissertation. Michigan Tech’s supportive and collaborative environment has greatly contributed to my personal and professional growth.”
