Doctoral Finishing Fellowship – Fall 2021 Recipient – Yunxiang Ma

Published

I came from central China, where I was born and brought up. I obtained my Bachelor of Engineering degree in civil engineering from Xi’an Jiaotong-Liverpool University, a young collaborated university symbolizing the cooperation and communication between the oriental and western world. Then I went to the United Kingdom and got my master’s degree in structural engineering and mechanics from the University of Glasgow and Edinburgh University. I joined MTU in January 2018 and started my study and research life as a Ph.D. student. The study and journey told me to embrace the difference, learn from the best and do what I can.  

Currently, human society is facing some common and severe problems, such as the extreme weather caused by global warming, pollution, and the increasing cost of human resources. As a civil engineer, I would like to help with what I can do. In my vision, the buildings have to be more resilient, ecofriendly, and efficient in cost and human resources in the future. A fundamental improvement to thaw the problems a little would be the improvement of structural systems. I was clueless; then, I met the mass timber structures. Unlike the manufacture of cement, which incinerates stones, or the casting of steel, which melt and treat iron in a furnace, timber structural components manufacture requires much less energy and consolidate the carbon absorbed by the trees. However, despite the outstanding sustainability performance, as a type of natural material, the variation in the mechanical properties and the directional differences limited the utilization. In recent decades, engineered wood products such as CLT broke through the limit and showed great potential as a new and better structural system.

Nevertheless, there are still a lot of technical problems limiting the promotion of mass timber structures. As a civil engineer, I wish to contribute and gain success. I got an opportunity here in MTU to study the manufacture of CLT with low-value timber for first-hand experience. I am studying the CLT wall structures with advanced finite element analysis tools for the structural dynamic response, which could help design and develop mass timber structures. I greatly appreciate MTU and my advisors that provided me the opportunity. And I would like to sincerely thank the Graduate Dean Awards Advisory Panel for approving me for the finishing fellowship award. The award will help me to fully concentrate on finishing my study and dissertation for my Ph.D. degree. It will be a significant step for me to pursue my career and my dream.

I came to Michigan Tech in 2015 as a master’s student. Before this, I completed my undergraduate degree in mechanical engineering in NITK Surathkal, India. During my master’s degree, I was exposed to research work and enjoyed it very much. I like solving challenging problems and doing new things every day. Thus, I decided to pursue a Ph.D. degree which started in fall 2017 under the guidance of Dr. Youngchul Ra.

My research work deals with developing new accurate models for evaporation of liquid drops as well as wallfilms to be used in computational fluid dynamics (CFD) simulations. In particular, the first project involved the development of a model to predict pre-ignition (and thereby prevent) by lubrication oil drops in marine natural gas engines. Pre-ignition in marine engines can cause mechanical damage and thus financial loss. I have developed and tested a CFD computer code that can predict complex preignition processes. The second project was to develop a new analytical model for wallfilm evaporation. To lower emissions during the cold start of internal combustion (IC) engines, accurate modeling of the evaporation and heat transfer physics of wallfilm is required. First, the theoretical derivation of the model was developed. The model was then programed and implemented in KIVA-3V code. I hope my work will help engine/power plant designers and manufacturers to develop machines and processes that are more efficient, greener, and cleaner.

Now as I am closer to graduation, I am grateful to my advisor Dr. Ra for providing me valuable guidance. I also acknowledge the contribution of my lab mates who participated in our numerous discussions which helped me in my work. I sincerely thank the Graduate Dean Awards Advisory Panel and dean for awarding me this fellowship as it will help me concentrate on finishing my dissertation and defense.

Health and Safety Resources and Responses

*HuskyFAN Food and Delivery

Michigan Technological University’s campus food pantry, or HuskyFAN, moved their operations to include an online food order form. Through this form students, faculty and staff, can request items to be packaged and delivered or arrange a pick up day and time. Starting mid-September the food pantry will distribute vouchers to be used at the local Houghton Farmer’s Market. These can be used to purchase fresh produce.

*Provided Masks and Other Wellness Supplies

At the beginning of the fall 2020 semester, all student groups were provided a time to pick up a wellness packet which included a washable mask, hand sanitizer, and information on health and safety during the pandemic. Areas on campus including HuskyFAN and Residence Education and Housing, and Center for Student Mental Health and Well-Being have continued to provide masks and other wellness supplies like cleaners, wipes, and hand sanitizer to all students upon request.

*Telehealth

Michigan Technological University’s Center for Student Mental Health and Well-Being (CSMWWB) moved their operations online including the Graduate Student Support Group. Recognizing the need for additional mental health and well-being resources, the CSMWWB has launched another telehealth option through MySSP.

*On Campus Testing and Symptom Monitoring

Throughout the 2020-2021 academic year, Michigan Technological University encouraged, and at times required, all students to use the Daily Symptom Monitoring Form which provided the necessary offices with information to support students who felt unwell. On demand COVID-19 testing has continued to be available to students, faculty and staff throughout the academic year.

*Isolation/Quarantine Spaces

Throughout the pandemic multiple departments on campus (Residence Education & Housing Services, Graduate School, Dean of Students Office) worked together to ensure students had safe spaces if they were required to isolate or quarantine. During an isolation or quarantine period, students were contacted often to provide them with resources including food delivery, virtual engagement opportunities, mental health resources, assistance with children, and many other resources.

Financial Resources and Responses

*Emergency Funds

Even before the pandemic began, Michigan Technological University had a process in place for students to request emergency funds for extenuating circumstances. At the start of the pandemic, the decision was made to loosen the eligibility requirements of the emergency funds in order to allow as many students as possible the opportunity to apply. Over the last year and a half, Michigan Technological University has given out over $100,000. In addition, the Graduate School was gifted $100,000 which was distributed to graduate students in need.

Distribution of CARES Funds

For eligible students, CARES funds were distributed through block payments. Upcoming CARES funds will be distributed in a similar manner.

Daniell Heights

Policies regarding evictions and late fees were relaxed. Students with a payment plan in place could remain in their housing and late fees were waived.

Academic Related Resources and Responses

Deadline Flexibility

Many different deadlines including time for completion of an incomplete grade,and date for withdrawal with a “W”,  were extended for all students during the spring 2020, fall 2020, and spring 2021 semesters.

Course Retake Policy

The policy for the number and type of courses that can be retaken has been modified. Any courses taken during spring 2020, summer 2020, fall 2020 and spring 2021 will not count toward the limit of retaking a class a maximum of three times as stated in the University policy and may be repeated, regardless of the grade that was received.

Pass/Fail Grades

In the spring 2020, and fall 2020 semesters students were provided with the opportunity to choose a Pass/ Low Pass/ Fail Option as Michigan Technological University recognized that the alternative modalities for classes may not have been ideal for all types of students.

Suspensions/Dismissals

In spring 2020 the Graduate School amended the policy for Good Academic Standing and Dismissal to not penalize any students who may have been placed on probation, suspension, or dismissal.

Transition to Health and Safety Level Two

Published
By

Message from Dr. Koubek from August 5, 2021.

Since the onset of the pandemic, we have worked to create a healthy and safe on-campus experience for our students, faculty, and staff—one that we can flex in response to rapidly changing environments. We have also learned that technology (while great) cannot replace the experiential learning that happens in classrooms, labs, residence halls, and beyond. For these reasons, we are delighted to welcome our students back to campus for a normal start to the fall semester.

To best ensure the continuity of campus operations, Michigan Tech strongly recommends that all employees and students receive the COVID-19 vaccine, especially in light of the virulence of the COVID-19 delta variant. 

With all of this in mind and out of an abundance of caution, Michigan Tech will return to Health and Safety Level Two as outlined in our MTU Flex plan, effective August 15, 2021, for at least five weeks. This includes reinstating an indoor face covering requirement for all faculty, staff, students, and visitors (regardless of vaccination status).

During the first few weeks of the semester, we will continue to review available data to inform our pandemic mitigation strategy. Our hope is that Michigan Tech’s face covering requirement is short-term. Our goal is to return to a face-covering-optional environment once we have more information regarding the spread of COVID-19 within our campus community.  In the meantime, I ask that you continue to do your part to help keep our campus and community safe. I look forward to seeing you all on campus soon.

Nominee for 2021 CGS/ProQuest Distinguished Dissertation Award: Hongmei Lu

Published
By

The Graduate School is pleased to announce that Hongmei Lu is Michigan Tech’s nominee for the 2021 CGS/ProQuest Distinguished Dissertation Award in the area of Humanities and Fine Arts.  Dr. Lu received her Ph.D. in Environmental and Energy Policy in the department of Social Sciences in 2020 and was advised by Dr. Audrey Mayer.  Her dissertation was entitled, “From Garden City to Sponge City: Urban Green Infrastructure Policy Development.”  As described by her advisor, her dissertation focused on Chinese policies and policy actors in the rapidly-emerging area of urban green infrastructure. Green infrastructure is increasingly used around the world to solve common environmental problems in cities, such as flooding, air pollution, and climate change. In China, as in the rest of the world, urban green infrastructure has a significant environmental justice dimension; green space is more commonly found in wealthier neighborhoods and has a positive feedback effect on real estate prices and rents. In response to the rapid urbanization of China, the central government has put forth an increasing number of policies (such as the Sponge City program) to try to address flooding and pollution issues through the implementation of green infrastructure. As Hongmei’s work is revealing, the success or failure of these policies often rely upon the presence of astute policy agents who can shepherd programs and projects through a sometimes-byzantine bureaucratic system.

Currently, Dr. Lu is working with Dr. Angie Carter on a community-based research project of local food system development in the Western Upper Peninsula, Michigan, and explores how grassroots co-production of a local food system can improve community wellbeing, especially food security and food sovereignty during and after the COVID-19 pandemic.

Dr. Lu was nominated by the Social Sciences department and the nomination was supported by Dr. Audrey Mayer, Dr. Shan Zhou, and Dr. Melissa Baird.

The CGS/ProQuest Award operates on a two-year cycle with regard to fields of competition. The next competition will occur in 2022 and will consider applicants who have completed their degrees between July 1, 2021, to June 30, 2022 in the fields of Mathematics, Physical Sciences & Engineering; and the Social Sciences.  Please consider nominating your Ph.D. graduates next year.

Doctoral Finishing Fellowship Summer 2021 Recipient – Oudumbar Rajput

Published
By

I obtained my Bachelor of Engineering degree in Mechanical Engineering from University of Pune in 2013.I started my graduate studies at Michigan Technological University in Fall 2015. During my master’s degree program, I joined Dr. Youngchul Ra’s research lab (Reacting Flows and Fuel Research Lab) at Mechanical Engineering-Engineering Mechanics department and started my Ph.D. program in January 2017. The focal point of my research is to use in-house computational fluid dynamics tool to numerically develop a novel six-stroke gasoline compression ignition (6S-GCI) engine cycle to improve fuel consumption, reduce emissions, extend the operating range of conventional four-stroke GCI, and stabilize the engine operation at low loads.

A high compression ratio engine with two intake/exhaust valves is used for this work. The first task completed focused on understanding the impact of valve opening/closing timings on the overall combustion behavior in 6S-GCI engine. It successfully demonstrated that the 6S-GCI cycle improves fuel consumption compared to corresponding four-stroke operation. An important finding is that both kinetically-controlled mode (KCM) and mixing-controlled mode (MCM) of combustion could be achieved in the second power stroke maintaining low soot levels. Next, attention was paid to understand the underlying physics of combustion regime change (KCM/MCM). To achieve this, the impact of the variation of split ratio (ratio in which total fuel was divided amongst both the power stokes), fuel injection timings, intake temperature, boost pressure, EGR ratio, and injection pressure on overall combustion and emissions performance was analyzed. Finally, the effects of injector configuration and piston bowl geometry characteristics on fuel oxidation rates and formation and oxidation rates of emissions were analyzed. The work completed thus far helps not only to gain an understanding of the mechanism of enhancement of combustion phasing controllability, stabilizing of engine operation at low engine loads, and improvement of combustion efficiency, but also in planning new experiments, and in designing new engines.

I would like to sincerely thank the Graduate Dean Awards Advisory Panel for providing me with the Finishing Fellowship award. This will allow me to focus on defending my dissertation in summer 2021.

Doctoral Finishing Fellowship Summer 2021 Recipient – Sandip Aryal

Published
By

I joined Michigan Tech in Fall 2018 as a graduate student in the Department of Physics and began working with Dr. Ranjit Pati. Before coming here, I completed a Master’s from the University of Utah and a postgraduate diploma in condensed matter and statistical physics from International Centre for Theoretical Physics (ICTP).

At MTU, my research focuses on the prediction of new materials with novel properties using density functional theory (DFT) and spin transport in these materials using DFT and non-equilibrium Green’s function method for possible applications in spintronic devices. In these three years, I have completed a couple of research projects under the supervision of my advisor in which we tailored the properties of pristine semiconducting Ge-Si core-shell nanowire via doping of transition metals to predict a new class of materials. We then theoretically showed that the newly tailored materials act as an excellent spin filter (Mn-doped devices) or a switch (Cr-doped devices) with a high ON-OFF current ratio. Our results have laid the foundations for experiments and are expected to generate experimental interest in the near future due to compatibility with the current Si-based technology for potential applications in low dimensional spintronics.

I am extremely grateful to the graduate school (MTU) for supporting me through the doctoral finishing fellowship during the summer semester. I believe that this fellowship will allow me to concentrate completely on writing my dissertation and graduate sooner.
