I started my doctoral research in Spring 2018 with Dr. Christo Z. Christov in the Department of Chemistry at Michigan Technological University. Before that, I completed my B. Tech. in Chemical Engineering from Rashtrasant Tukadoji Maharaj Nagpur University was working as Project Research Assistant at the Indian Institute of Technology Bombay. My research focuses on utilizing computational techniques like Molecular Dynamics (MD), Quantum Mechanics (QM), and Quantum Mechanics/ Molecular Mechanics (QM/MM) to explore structure-function relationships in enzyme catalysis. 

During my time as a PhD candidate at Michigan Tech, I have researched an NSF funded project about ethylene forming enzyme. In this project, my research involved developing an enzyme model to establish the chemical mechanism of ethylene formation and L-Arg hydroxylation. I further explored if external electric fields can switch between the two reactivities of ethylene forming enzyme, with an aim to optimize ethylene generation. I have also worked on an NIH funded project about histone demethylases, activities of which have been linked to various forms of cancers. I used molecular dynamics simulations and combined QM/MM approach to establish the enzyme catalytic mechanism and structure-function relationship. Moreover, I have developed a computational framework for identifying second coordination sphere and long-range residues relevant for catalysis through analysis of protein correlated motions. 

I am grateful to the Graduate Dean Awards Advisory Panel and the Dean for awarding me the Doctoral Finishing Fellowship. I would also like to offer my special thanks to my advisor Dr. Christo Z. Christov, for his support throughout my PhD program.

My love for optics and photonics is deep in my core. I have always been fascinated and motivated by this area of physics. Everything fascinated me, from natural phenomena to optical illusions, from ray optics to wave optics, from ordinary materials to extraordinary materials with optical effects. While my journey in optics and photonics was inevitable, it never lacked an element of surprise. 

I started my PhD here at Michigan Tech in Fall 2018, in the Department of Physics with Dr. Miguel Levy as my advisor. In my research, I focus on investigating the fundamental properties of ultra-thin magneto-optics materials. The surface effects we are investigating will lead to the miniaturization of laser components named optical isolator and, thus, the miniaturization of lasers. We researched the experimental aspects of these properties and the theoretical, i.e., density functional theory aspect of it. This gives a complete picture of our investigation of the non-reciprocity property, i.e., Faraday rotation.  

During my time at Michigan Tech, I made friends and family who helped me grow as a physicist and a better human being. Now that it’s almost time for my journey at Michigan Tech to end soon, I am sure the memories and lessons learned during these five years will always stay with me and guide me in my future endeavors. 

I am indebted to the Graduate Dean Awards Advisory panel for considering and awarding me this fellowship. I am grateful to my advisor; Dr. Levy’s teachings helped me become a better person and student. He always inspired me to contribute to the community while contributing to physics. I am proud and honored to be his student.

In the spring of 2017, I started my journey at MTU as a Ph.D. student in Chemistry. The focus of my Ph.D. research is on the design and development of carbon dots (CDs) which are fluorescent nanomaterials with great potential in sensing and bioimaging. During my Ph.D., I could successfully synthesize high quantum yield CDs for iron ions sensing with the potential to be used in the clinical diagnosis of iron-related diseases or environmental monitoring of water quality. Also, I investigated the design of near-infrared nitrogen-doped CDs that would be ideal for bioimaging applications.

It is a great honor to receive the Doctoral Finishing Fellowship, and I am grateful to the graduate school and the Graduate Dean Awards Advisory Panel for their support. Through this fellowship, I will be able to focus on writing my dissertation and publishing my work in journals. Additionally, I would like to take this opportunity to thank my advisor, Dr. Patricia Heiden, for her help and support throughout my Ph.D. journey.

I started my Ph.D. journey in Fall 2017 as a graduate student in the Department of Physics under Dr. Dongyan Zhang and Dr. Yoke Khin Yap. Prior to that, I completed my Master’s degree from Tribhuvan University, Nepal. 

My Ph.D. research focuses on the synthesis and application of Boron Nitride (BN) nanostructures specifically nanotubes (1D) and dots (0D). BN nanostructures have gained much attention due to their unique optoelectronic and biocompatible properties. Controlling the diameter of BN nanotubes using Catalytic Chemical Vapor Deposition (CCVD) is one of the major challenges especially getting a smaller diameter (<20nm). I was able to reduce the diameter of the BN nanotubes to 10-20nm using CCVD in contrast to >20nm from earlier research. These small diameter nanotubes can be used in electronic as well as biomedical applications. Besides nanotubes, I have developed a procedure to synthesize BN dots, zero-dimensional fluorescent materials. I have successfully used these dots for fabricating solar cells, in the future, this can be used in solar panels for clean energy generation. Further, I am currently evaluating the potential of using these self-fluorescing dots as fluorescent tags on RNA inside cells. If successful, this can be used for bio-imaging and as an RNA therapeutic for different kinds of diseases. Initial biocompatibility and cell internalization test performed in Hela cells (cervical cancer cells) are showing promising results.   

I am thankful to my advisors, Dr. Zhang and Dr. Yap, for their constant guidance throughout my Ph.D. journey. I am extremely grateful to the Graduate Dean Awards Advisory Panel for providing this finishing fellowship award at this moment. This fellowship will help me focus more on writing my dissertation and graduate on time

I started my Ph.D. program in the Physics Department at Michigan Tech in the fall of 2017 and joined Dr. Nakamura’s group. There I focused on studying lithium dendrite growth in electrolytes using Monte Carlo simulations and deep neural networks in machine learning methods. Motivated by our collaborator’s experiment, I discovered a new mechanism for inhibiting the dendrite growth with large organic salts, such as ionic liquids. Through my research and coursework experiences, I have solidified my confidence in various physics subjects. These include soft-matter physics, solid-state physics, computational physics, physical chemistry, and computer science. As I approach the end of my Ph.D. program, I am currently addressing the challenge of overcoming the vast computational expense of molecular dynamics simulations for salt-free and salt-doped liquids. In order to address this, I am further developing my deep neural network models.

I have enjoyed my Ph.D. life; Houghton has the most beautiful summers I have ever seen. I greatly appreciate the Graduate Dean Awards Advisory Panel and the Dean for granting me the Finishing Fellowship. I would also like to thank my supervisor, Dr. Issei Nakamura, for his enlightening guidance throughout my research, as well as the Physics Department for all their support.

Born and raised in the Upper Peninsula, I started my journey in Manistique, MI and since then have slowly migrated an hour and a half northwest every handful of years. The first time was after high school where I then attended undergraduate studies at NMU and discovered I enjoyed research under some wonderful professors. The second time was to come here to MTU and conduct my doctoral research under Dr. Tarun Dam in the Lab of Mechanistic Glycobiology. We perform biochemical studies on therapeutically promising plant biomolecules as well as human proteins associated with diseases. We carry out fundamental investigations into the behavior of molecules in living systems. This has led me to learn a multitude of incredible techniques and instrumentation skills, foremost being electron microscopy here on campus which is now a passion of mine. I believe we do fascinating work while striving to always put our best foot forward. I would like to thank Michigan Tech and our graduate school for awarding me with the Finishing Fellowship, it is a great assistance to myself and our lab.

I come from Dhaka, the heart of beautiful Bangladesh where I obtained a BS in computer science and engineering from the Military Institute of Science and Technology. I was very keen to understand how to make human-system interaction more efficient, and therefore I started my journey for graduate studies in the Department of Cognitive and Learning Sciences at Michigan Tech in the summer of 2018. I completed my master’s degree in Applied Cognitive Science and Human factors in 2020 and currently, I am pursuing my Ph.D. in the same department under the supervision of Dr. Shane T. Mueller. I recognize myself as a human factors researcher working closely in the interdisciplinary area of public health, artificial intelligence (AI), and cognitive psychology.

I am exploring the human factors issues in patient-AI interactions within the context of diagnostic healthcare. Working on my master’s thesis, I found the empathetic aspects are important in physician-patient communication and it may have some prospects within AI-patient communication as well. While it is very challenging to incorporate cognitive empathy elements within an artificial agent, I started thinking about how this issue can be addressed and chose these research questions to pursue my dissertation, I have extracted cognitive empathic elements of patient-physician communication by interviewing first-time mothers to understand their interactions with their physicians and midwives. Currently, I am examining the effectiveness of these elements within the context of patient-AI communication. My research objective is to bridge the gap between patient and AI using cognitive empathy elements, develop common ground in patient-AI communication, and help people trust the available AI resources.

I am extremely grateful to the Portage Health Foundation (PHF) for acknowledging my work with patient-physician communication by awarding me the graduate assistantship for Summer 2022. I would also like to express my gratitude to my advisor Dr. Shane T. Mueller for guiding me at every step in the last 4 years. I thank the Institute of Computing and Cybersystems (ICC) for supporting my research, also each and everyone in the department of Cognitive and Learning Sciences for providing me with a wonderful and friendly environment to grow as a person and a researcher. With this assistantship, I believe I will make good contributions to the health research for the community by developing resources for expecting mothers based on my research so that they may build a rapport with their providers. The assistantship will also help me to exclusively focus on my dissertation and work towards achieving my goals.

Michigan Tech gratefully acknowledges support from the Portage Health Fountain for the PHF Graduate Assistantship.

MTU Students Receive NSF Graduate Research Fellowships

Published
By

Two Michigan Tech graduate students, Tessa Steenwinkel and Tyler LeMahieu, have been awarded National Science Foundation (NSF) Graduate Research Fellowships, and one undergraduate student, Jenna Brewer, has been given an honorable mention.

The oldest STEM-related fellowship program in the United States, the NSF Graduate Research Fellowship Program (GRFP) is a prestigious award that recognizes exceptional graduate students in science, technology, engineering and mathematics (STEM) disciplines early in their career and supports them through graduate education. NSF-GRFP fellows are an exceptional group; 42 fellows have become Nobel Laureates and about 450 fellows are members of the National Academy of Sciences.

The fellowship provides three years of financial support, including a $34,000 stipend for each fellow and a $12,000 cost-of-education allowance for the fellow’s institution. Besides financial support for fellows, the GRFP provides opportunities for research in national laboratories and international research.

The Graduate School is proud of these students for their outstanding scholarship. These awards highlight the quality of students at Michigan Tech, the innovative work they have accomplished, the potential for leadership and impact in science and engineering that the country recognizes in these students and the incredible role that faculty play in students’ academic success.

Tessa Steenwinkel

Steenwinkel is a biochemistry and molecular biology M.S. student under advisor Thomas Werner (BioSci). She has been studying the influence of nutrition on the interplay of fertility, fecundity and longevity in Drosophila. In the long term, she plans to focus on medicinal research and how genetic regulation plays a role in infertility

Werner writes: “Tessa is the best student I have ever had the pleasure to mentor in my lab. During her undergraduate and accelerated M.S. years, she won nine research awards and published 10 research papers and two books with me. I am extremely happy (but not surprised) that she won the NSF Graduate Research Fellowship. Her newest success proves that I was not mistaken in my choice to name a new fruit fly species in her honor last year, which is named ‘Amiota tessae.'”

Tyler LeMahieu

LeMahieu is an environmental engineering M.S. student under advisor Cory McDonald. LeMahieu’s proposal was titled, “Understanding Wild Rice Site Suitability in a Changing Climate.”

LeMahieu writes: “I plan to dedicate my career to bridging gaps between the scientific body and land managers. I would like to manage public and rural lands for the farmer, the logger and the hunter while managing those same lands for improved water and ecological health into perpetuity. Because fundamentally, rural land managers have the same goal in mind as those studying the environment — a useful, productive and sound ecosystem which will support and be supported by the next generation. That common ground is not always evident to both parties, but I am equipped to act as an intermediary with a foot in both worlds.”

Jenna Brewer

Brewer is a senior undergraduate student from Grand Rapids studying wildlife ecology and management under advisor Jared Wolfe. She plans to continue her education at Michigan Tech, pursuing a graduate degree this fall. Her research aims to develop an acoustic signal to deter birds from potential collision hazards such as city buildings during flight, effectively mitigating bird deaths. After graduate school, she hopes to become an avian ecologist, contributing to projects that focus on migration science.

Wolfe writes: “Jenna’s enthusiastic study of songbird ecology and conservation has long been recognized by her supervisors and peers; now that same passion has been recognized by the National Science Foundation. Faculty at CFRES are incredibly proud of Jenna’s accomplishment!”
