I began my PhD journey in Fall 2019 in the Electrical and Computer Engineering (ECE) department studying underwater acoustic communication systems. After taking a machine learning course, I decided I wanted to make machine learning and artificial intelligence a larger focus of my studies and ultimately joined a project focused on natural language processing (NLP) technologies for the summarization of dialogue.

My main dissertation chapters primarily focus on text summarization (how to concisely and accurately represent a large body of text with a small one) and segmentation (how to split up long chunks of dialogue into smaller ones). In my favorite chapter contained in the dissertation, I propose a text segmentation metric that goes beyond current segmentation metrics by scoring a segmentation set without requiring a human to provide a reference, which is currently required by all existing segmentation metrics. I continued this segmentation work by considering the case of fuzzy text segmentation, where the boundaries between segments are no longer solid and a sentence within a document can belong partly to multiple segments.

The papers on summarization are still in preparation, with one discussing a small model architecture modification to improve summarization quality and another exploring methods of demonstrating summarization model ownership by adding watermarks to generated content. As language models become more widely used, concerns about their use will continue to grow; one solution to this is to have ways of detecting or proving that the origin of text comes from a language model. In addition to these papers, I have also published on a technique for using limited human feedback in the form of a binary good/bad response to help improve model performance for classification models that contain more than two classes.

I would like to thank my advisor, Dr. Timothy Havens, for his support, encouragement, and guidance throughout my PhD. The last two years of my work would also not have been possible without the support of Bob Friday and Paul Fulton from Visionyze; they have funded my research up until this point and collaborated with me on several projects. I’d also like to thank my committee and the ECE department for their support along the way. Finally, I am incredibly grateful to the Graduate School as well as the Graduate School Awards Advisory Panel for awarding me this fellowship, which will help me complete my dissertation and finish publishing the last papers of my PhD.

My research centers on the human factor aspects of Advanced Driver Assist Systems (ADAS). ADAS features are semi-autonomous features that enable drivers to relinquish operational control of the vehicle to automate part of the total drive. Features that use ADAS, like Tesla’s Autopilot (hands-on-wheel) or Cadillac’s Super Cruise (hands-free), are not entirely self-driving and require drivers to monitor their environment if the automation turns off or malfunctions. Drivers’ inconsistencies in monitoring the external driving environment and the automation status have led to several high-profile accidents involving these semi-automated features. While these features are currently commercially employed, little research to date documents their impact on their effectiveness in promoting driver attention while automation is engaged.

The objective of my work is to understand how the hands-on-wheel and hands-free driver supervision strategies differently affect situational awareness and takeover performance after automated driving. Moreover, my work explores how physiological performance metrics like eye tracking predict the drivers’ cognitive state and the likelihood of making errors. My work has already demonstrated that the hands-free driver supervision strategies fail to mitigate mind wandering and put drivers at higher risk of failing to detect safety-critical changes to the driving environment.

I thank the Graduate Dean Awards Advisory Panel for awarding me with this fellowship. This fellowship will enable me to complete data analysis from my most recent study and dissertation writing. I am deeply indebted to my advisor Dr. Kelly Steelman for her unconditional support in my research endeavors. Additionally, I would like to thank my committee members, Dr. Shane Mueller, Dr. Beth Veinott, and Dr. Joonbum Lee for their invaluable guidance. And last but not least, I would like to give a quick shout-out to the entire CLS department for their support throughout this process.

During my master’s degree program, I worked as a Research Assistant at the Council for Scientific and Industrial Research (CSIR)-Forestry Research Institute of Ghana under the supervision of Prof. Emmanuel Opuni-Frimpong. There, I worked on Clean Development Mechanism and Mahogany projects, funded by International Tropical Timber Organization (ITTO). The passion and zeal I demonstrated in the research activities made me realize I had an interest in a long-term career in ecological and forestry research. Though I joined the forestry industry upon obtaining my master’s degree, I always had my mind and heart fixed on returning to a research environment to contribute to finding solutions to numerous ecological challenges faced as a society.

It was, therefore, refreshing when I was awarded a graduate scholarship to study PhD in Forest Science at Michigan Technological University under the advisement of Dr. Andrew J. Burton. Since joining MTU, I have been working on the Face Wood Decomposition Experiment (FWDE) project funded by NSF, where logs of trembling aspen, paper birch, and loblolly pine with distinct isotopic signatures were deployed across nine diverse forest sites of the conterminous United States to monitor wood decomposition and carbon transfer to soil. On this project, I have worked to improve our understanding of terrestrial carbon cycling by analyzing soils collected beneath the decomposing logs and quantified the proportions of the logs’ carbon moved into soil carbon pools. I have also examined the mechanisms (e.g., site, log species type, and termites) that drive the logs’ carbon incorporation into soil pools. For the first time, my doctoral research is providing this important information critical to advancing terrestrial carbon modeling and as well improve soil carbon sequestration management options in response to management practices and climate-related impacts.

I sincerely thank my advisor Dr. Andrew J. Burton, who has been unrelenting in his support and guidance throughout my PhD journey. My sincere gratitude to my committee members and the College of Forest Resources and Environmental Science for their support throughout my stay in the program. I am also grateful to the Graduate Dean Awards Advisory Panel, the Dean and the Graduate school for awarding me the Doctoral Finishing Fellowship. The Fellowship would let me stay focused on completing my PhD dissertation during the coming summer

I completed my bachelor’s and master’s degrees at the University of Peradeniya in Sri Lanka. In the fall of 2018, I started my PhD in chemistry at Michigan Tech and joined the research group of Dr. Lynn Mazzoleni. The group’s primary research focuses on using ultrahigh-resolution mass spectrometry to study the chemistry of organic aerosols in the atmosphere.


In my research, I have developed a new post-data processing approach for liquid chromatographic high-resolution mass spectrometric data. The need for this approach arose from the requirement to effectively analyze complex mixtures in the environment. Mimicking ambient BBOA is one of the significant challenges scientists face in atmospheric research. Therefore, I improved liquid smoke to simulate the ambient BBOA by mixing them with different environmental species. This significantly impacts aerosol research as it provides an option for environmentally relevant lab studies.


I would like to thank my advisor Dr. Lynn Mazzoleni for her guidance, support, and encouragement during my research journey. Her mentorship has been invaluable to me and has played an integral role in helping me with my accomplishment. Also, I sincerely thank the Graduate Dean Awards Advisory Panel for selecting me as a recipient of the finishing fellowship, which will allow me to focus on finishing my dissertation and publishing my work.

I started my PhD journey in 2019 and currently work with Dr. Julia Burton and Dr. Christopher Webster at the College of Forest Resources and Environmental Science. My research is part of the “Northern Hardwood Silviculture Experiment to Enhance Diversity,” where I investigate how plant species in managed northern hardwood forests respond to different environmental factors and silvicultural practices. Forests provide crucial economic and ecological services, and my work aims to develop sustainable management strategies that balance profitable forests and the conservation of forest services in the future. With the arising challenges posed by climate change, it is essential to address the risk of losing biodiversity and explore ways to maintain and enhance the species composition in managed forests. In addition to my research, I have a passion for teaching. As a former teaching assistant at Michigan Tech, I have found sharing knowledge to be rewarding and plan to include it in my future career. 

I am deeply grateful for being awarded the Finishing Fellowship. Receiving the Fellowship is an incredible honor and allows me to focus on completing my degree and publishing my research. I would also like to extend my gratitude to my co-advisors, Dr. Julia Burton and Dr. Christopher Webster, and the members of my advisory committee, Dr. Robert Froese, Dr. Yvette Dickinson, and Dr. Chelsea Schelly, for their constant support and guidance. Further thanks also to the College of Forest Resources and Environmental Science for creating an encouraging community and an exceptional academic environment, contributing to both my personal and professional growth.

I am excited about the opportunities that lie ahead and look forward to finishing my dissertation and taking on new challenges.

I started my PhD in the Department of Mathematical Sciences at Michigan Tech in the Fall of 2018, with a discrete mathematical background. But, my enthusiasm grew for Applied Mathematics, especially for the research problems to which I can relate real-life Scenarios.

Therefore, under the tutelage of my advisor Dr. Alexander Labovsky, I started to study incompressible flows, especially in turbulent regime.

Turbulence is a wonderful area of research. While the Navier-Stokes Equations are used to study the flow, one can only simulate the flow in turbulent situations. When simulation methods are used, there is always the need for new high-accuracy methods.

Moreover, in the presence of a magnetic field, the characteristics of the flow will change, leading to the Magneto-Hydrodynamic system to simulate the flow. Therefore, my area of research interest includes the study of Navier-Stokes Equation, Magneto-Hydrodynamic Equation, Large Eddy Simulation, and high-accuracy methods that can be developed separately, or along with turbulence modeling.

I’m grateful to my advisor for the kind guidance and support. I’m really honored to be his student. Also, I thank the Department of Mathematical Sciences for nurturing me to excel in both research and teaching.

Finally, I’m grateful to the Graduate Dean Awards Advisory Panel and the Graduate school for considering and awarding me this fellowship which will be a great support.

Michigan Tech gratefully acknowledges support from The Dr. Donald Dawson Endowed Finishing Fellowship for this award.

My name is Tiff DeGroot, and I am a PhD Candidate in Forest Science in the College of Forest Resources and Environmental Science. I came to Michigan Tech through a winding path. In my early 20s, I waited tables and cleaned horse stalls to pay for general education courses until I could transfer into a bachelor’s program. Then I completed my BS in Biochemistry, Molecular, and Cellular Biology at the University of New Hampshire, while working nights and weekends at an indoor skydiving facility. After graduation, I saved up as much money as I could and purchased a plane ticket to South Africa to pursue my lifelong dream of studying African wildlife. I saw my first wild giraffe, tracked elephants and cheetahs, and set up camera traps to monitor leopards. When I returned to the US, I joined a global conservation non-profit, the International Fund for Animal Welfare (IFAW). My position at IFAW focused on communicating conservation efforts to a broad audience. 

With a background in science and a keen interest in applied conservation, I decided to return to academia. I started by pursuing a Master’s Degree in Forest Ecology and Management at Michigan Tech. My project focused on camera trapping and noninvasive methods of mammal monitoring in Equatorial Guinea in central Africa. After one semester, I was invited to expand this project to a PhD. My project now spans multiple spatial scales, and will address mammal diversity, distribution, and communities across Equatorial Guinea. The results of this research will not only contribute to the scientific community, but will also be used to directly inform the on-the-ground management of protected areas in Equatorial Guinea. 

When I am not in the lab, coding, or sorting camera trap photos, you can usually find me in my garden, training my rescue dog, or in the pottery studio.

I am incredibly grateful to the DeVlieg Foundation for allowing me the opportunity to focus on my project this summer. With an entire semester dedicated to my work, I will make good progress towards my second publication by completing a study that compares the use of camera trapping and environmentally-derived DNA (a non-invasive genetic monitoring technique) to assess mammalian diversity in Equatorial Guinea.

Michigan Tech gratefully acknowledges support from The DeVlieg Foundation for the DeVlieg Summer Research Award.

I started working at the APS LABS for my Masters’ thesis in Fall 2017. The research and the people at the APS are so amazing, that it wasn’t a difficult decision to stay for my PhD. I started my PhD in Summer 2018 under the guidance of Dr. Jeremy Worm, who is the associate director of APS LABS.

Majority of my PhD work has been on gasoline engines- how they can be further improved and made more efficient. The projects I have worked on have been industrial projects for major automotive companies like General Motors, Ford, Stellantis and Nostrum Energy. The current automotive climate is all about electrification. But I believe that the internal combustion engine, which is one of the major factors that has brought civilization to the advanced stage it is at right now, still has a massive role to play in the future. But the beauty of working at the APS LABS is that you are not confined to a single subject, and get exposure to all sorts of power systems. In the last five years, I have worked with hybrid electric vehicles as well, and also on a project to consider the environmental and economic impacts of electrifying the Mackinac Island ferry.

The last five years have been memorable and fulfilling, and a lot of that is thanks to my advisor, Dr. Jeremy Worm. With the help of the Finishing Fellowship, I will be able to write the final chapter of doctoral journey (figuratively and literally), and move a step closer to my goal of becoming an academic.

From a young age, I always wanted to understand how the world worked and took a deep interest in science. I was constantly asking big questions, such as why do objects act as they do, what happens if you keep cutting an object, and how did the universe begin. This led me to become interested in physics, which seemed to focus on the most fundamental aspects of our universe. I was drawn to the way that physicists use experiments and math to explain the behavior of matter and energy at the smallest and largest scales. I loved reading about the latest discoveries in physics and learning about the theories that scientists were developing to explain them, and wanted to understand for myself. Pursuing this goal led me to my current path.

I began my PhD in 2019 following my Masters, working under the advisory of Dr. Issei Nakamura in the Department of Physics. My research has focused on utilizing molecular dynamics simulations to model highly charged and polar liquids, with emphasis on ionic liquids and polymerized ionic liquids. These materials have potential uses as electrolytes in batteries and supercapacitors, as nanolubricants in molecular devices, for phase separation of HFCs, and much more. These materials are interesting from a fundamental physics perspective as well, since the complicated nature of their dielectric properties are not well understood in the current literature. My work has helped uncover an understanding behind these properties as well as showing the capabilities and pushing boundaries of models used to simulate these materials.

My utmost thanks to the Graduate Dean Awards Advisory Panel for awarding me this finishing fellowship. I would also like to thank my graduate advisor Dr. Issei Nakamura and the Department of Physics at Michigan Tech for the support through this process of the PhD and providing such fantastic opportunities for learning, growth, and experience.
