My interests lie at the intersection of accessibility and efficiency. For this reason, I transitioned away from clinical work and started my PhD in Applied Cognitive Science and Human Factors in January 2019 under the guidance of Dr. Kevin Trewartha. From day one, my research has focused on developing new tools for assessing cognitive decline in older adults through the study of motor skill learning using a specialized robotic device.

My dissertation research focuses on the use of two novel motor skill learning tasks to distinguish between healthy aging, mild cognitive impairment, and the early stages of Alzheimer’s disease. Cognitive decline associated with Alzheimer’s is typically measured using neuropsychological tests that lack sensitivity and specificity to subtle changes in cognitive function associated with disease progression. As such, these tests struggle to correctly diagnoses patients with pre-clinical dementia symptoms (such as mild cognitive impairment) or the early stage of Alzheimer’s disease. Recent research, however, has shown that the ability to adapt our movements to learn a new motor skill may relate to changes in learning and memory that occur early in the development of the disease. My dissertation will explore the relationship between data collected from two motor learning tasks and data collected through a typical battery of neuropsychological tests to diagnose Alzheimer’s-type dementia. We expect that these motor learning tasks can go above and beyond the ability of the neuropsychological battery to detect changes in cognitive functioning. Importantly, these motor learning tasks take about half the time to complete compared to the standard diagnostic procedures. By showing that these tasks are sensitive to subtle changes in cognitive decline, we can increase certainty in the proper diagnosis while minimizing the time and costs associated with the diagnostic procedure. This could lead to earlier and more efficient diagnoses and subsequent earlier treatment to slow the progression of cognitive decline, thereby improving patient and caregiver quality of life.

I would like to thank the Graduate School Awards Advisory Panel for this fellowship, and my advisor, Dr. Kevin Trewartha, for his consistent support and guidance over the last four years.

I started collecting tropical plant physiology data for Dr. Molly Cavaleri as a plant physiology technician in October 2018 and started as a PhD student in her lab within the year. My interests in plant physiology are applied to how plants will respond to environmental forcings caused by climate change. Since plants are both a sink and source for atmospheric carbon, climate change effects on plant physiology will feedback responses to atmospheric carbon. I have been working at the Tropical Responses to Altered Climate Experiment (TRACE), a tropical understory warming experiment located in Puerto Rico, where I have been measuring plant responses to +4 °C experimental warming. I have been looking at acclimation responses to warming in leaf and root respiration, photosynthesis, and the limits for high-heat tolerance in leaves. All of these projects that I have been working on are generating data that will be fed into global models that predict how tropical forests will interact with the atmosphere under different climate scenarios. 

The next step in my career is to start the postdoctoral fellowship I have accepted at Michigan Tech in collaboration with several federal agencies to do the modeling work on the data I collected during my PhD. Dr. Molly Cavaleri, my committee, the College of Forest Resources and Environmental Science, and the TRACE team have all been amazing to work with and I look forward to working with them more over the next couple of years. I would also like to express my thanks to those who fund the Finishing Fellowship award and gave me the opportunity to spend an extra semester writing up the exciting work I have been doing as PhD student.

When I was in middle school there was a question on a standardized test about the water table. I had never heard that term before and was completely confused, having no clue what it meant.  That moment sparked a natural curiosity in me about groundwater and prompted me to learn more. When I took a hydrogeology course at Michigan Tech during undergrad, taught by my now co-advisor, I knew that this was the field I wanted to go into. Not only did I find it interesting from a scientific viewpoint, but also working in this field allows me the opportunity to work on projects that positively impact people and the environment.

I eventually returned to Michigan Tech in Fall 2018 to pursue a PhD in Environmental Engineering.  My research focuses on the process of groundwater inundation (flooding) driven by sea level rise on small islands. As sea level rises, the water table also rises and can flood low lying areas. This flooding exposes what was once groundwater to evaporation, leading to an accelerated loss of freshwater.  My work uses numerical modeling to better understand groundwater inundation and explore the relationship between hydrogeologic features, fresh groundwater, and lake salinity on small islands.

I am truly grateful to the Graduate Dean Awards Advisory Panel for awarding me with this fellowship. I would also like to thank my co-advisors, Alex Mayer and Dave Watkins, and my committee for all of their guidance and support through my pursuit of this degree.

My interest in the field of fuel cells was ignited when I was a master’s student in China. I enjoyed the sense of achievement when I constructed my first small fuel cell device that successfully converted hydrogen to electricity. I wished to broaden my vision in this field and prepare myself to be a qualified researcher with international experience, thus I started my PhD study at the Department of Materials Science and Engineering under the guidance of Prof. Yun Hang Hu in Spring 2018.

My PhD research focused on advanced electrode materials for solid oxide fuel cells. The stability of lithium-containing electrodes under fuel cell operating conditions was systematically investigated. Furthermore, a new fuel cell structure was designed based on the decomposition and diffusion of electrodes, achieving excellent device performance. I am pleased that my research could contribute to efficient and clean energy conversion technologies.

I would like to thank the graduate school and the evaluation panel for providing me with this important fellowship. This would help me concentrate on the completion of my PhD dissertation during the upcoming semester. I also sincerely appreciate my advisor, Prof. Hu, the MSE department, and my group members for all their support.

I started my Ph.D. program in Materials Science and Engineering at MTU under the supervision of Dr. Yun Hang Hu in the Fall of 2018. My research is focused on synthesis and characterization of novel graphene materials and their applications in energy conversion and storage, which have been further extended to water desalination and heavy metal removal based on my research background in water treatment. It is always exciting to see a project completed and published, knowing that my efforts would finally make a slight contribution to the world.


I am sincerely grateful to the Graduate Dean Awards Advisory Panel for awarding me the finishing fellowship, which would allow me to focus on my dissertation and defense. My special thank goes to my advisor, Dr. Yun Hang Hu, for providing not only conceptional and technical training crucial for an individual researcher, but also continuous guidance and encouragement whenever I doubted myself. I would also like to express my gratitude to my committee members (Dr. Ranjit Pati, Dr. Gerard Caneba, and Dr. Shiyue Fang), my lab members, and my family and friends for their invaluable help and support throughout my doctoral journey.

I returned to Michigan Tech for graduate studies in 2000 and soon started working as a staff researcher for Michigan’s Local Technical Assistance Program and later director of the Eastern Tribal Technical Assistance Program, two federally sponsored transportation research and technology transfer programs in the Civil and Environmental Engineering Department. I eventually left Michigan Tech as an employee but have continued work on my dissertation while developing a successful freelance technical communicator career. For the last 22 years I juggled work and family while chipping away at a masters in Rhetoric and Technical Communication and PhD in Rhetoric, Theory and Culture. 

Working in transportation may seem like a long way from the humanities, but transportation is a truly human endeavor. Unfortunately, one impact of transportation systems on humans (and non-humans) is a staggering toll of injuries and lives lost due to motor vehicle crashes. In 2020, nearly 39,000 people were killed in crashes in the US, and over 1.3 million people die annually in traffic-related crashes worldwide. Those most affected in the US are young rural and tribal people: A young American Indian or Alaska Native is 2-5 times more likely to die in a motor vehicle crash than the average American. Addressing this ongoing tragedy became my passion.

My research examines how we collect, analyze, and communicate risk, especially risk related to transportation. I have applied this research to help the most vulnerable populations—rural and tribal people in the US—understand transportation risk and safety in their own communities. By teaching people with few resources and knowledge how to evaluate and communicate risk in their own communities, local, non-experts can take steps to understand and mitigate risks from transportation and any other natural or anthropogenic causes. This work affected me so deeply that I even decided to become an EMT, firefighter, and EMT instructor so that I could directly apply this research and teach others how to understand and mitigate risk.

I am grateful to the many faculty and advisors who have worked with me in a decades-long education path at Michigan Tech, and especially thankful to my committee—Dr. Karla Kitalong, Dr. Andrew Fiss, Dr. Marika Seigel, and Dr. Melissa Baird—who have helped me stay committed to this work through a very difficult time for them and me in the past few years. I also thank the Graduate Dean Awards Advisory Panel for recognizing and supporting my unusual and drawn-out educational path with an award that will help me focus on completing my dissertation and degree. Last, but definitely not least, I thank my family for supporting me while I’ve always had too much on my plate! I look forward to continuing to learn and apply my education and research in our own community and to sharing this experience with others to help them live and thrive in communities large and small.

I came to Michigan Technological University in August 2018 to pursue a PhD degree in chemistry. I became interested in analytical chemistry during my undergraduate studies in polymer engineering and color science at the Amir Kabir University of Tehran, where I trained to design, synthesize, and analyze various materials such as polymers and pigments with industrial applications. Currently, my research focuses on using analytical techniques such as fluorescence spectroscopy and mass spectrometry to elucidate the origins of fluorescence in complex organic mixtures such as dissolved organic matter (DOM). DOM is one of the largest carbon reservoirs in soil and water, which plays a major role in global climate change and significantly impacts nutrient cycling for different ecosystems and their living organisms. 

During my journey as a PhD student, I have had many excellent learning opportunities while working as a teaching and research assistant. I collaborated on a research project with the department of natural resources and published a research paper titled “Insights on Dissolved Organic Matter Production Revealed by Removal of Charge-Transfer Interactions in Senescent Leaf Leachates” in the Water journal in August 2020. Also, I was fortunate to complete a 12-week co-op opportunity last summer, which helped me gain expertise in analytical techniques such as mass spectrometry, chromatography, and their applications in manufacturing and environmental studies. One of our most recent projects focuses on developing extraction methods and characterizing fluorescent compounds in animals to help us understand these species and their ecosystems more deeply. These natural fluorescent compounds can have various biological, medicinal, and industrial applications. 

I am immensely grateful to the Graduate Dean Awards Advisory Panel and the Dean for granting me this finishing fellowship award. I would like to thank my advisor, Dr. Sarah Green for being a great mentor and offering her continuous support and encouragement throughout my journey.
