“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.”
