Fatemeh Razaviamri – Biomedical Engineering

I am a third-year PhD student in the Biomedical Engineering department. My research focuses on designing polymeric biomaterials for antimicrobial, hemostatic, and wound healing applications under the supervision of Dr. Bruce Lee. Currently, I am working on a project aimed at developing a novel, antimicrobial hemostatic agent inspired by the strong adhesive properties of mussel adhesive proteins.

Hemorrhage is one of the leading preventable causes of death associated with trauma. Additionally, trauma patients are at a higher risk for developing infection, leading to substantial morbidity and mortality. I aim to develop a novel and portable hemostatic agent that could achieve hemorrhage control in a prehospital setting and prevent infection. This powder-form hemostatic agent can be activated by hydration through the patient’s bodily fluid or blood, which greatly simplifies the criteria for packaging and storage. The proposed hemostatic agent provides multiple mechanisms to prevent infection, including the ability to kill drug-resistant bacteria. The ability to disinfect the wound site in a prehospital setting will limit complications associated with infection and will greatly improve the rate of recovery.

I am immensely grateful for the support provided by the DeVlieg Foundation and the Graduate Dean Awards Advisory Panel. With their support, I will spend the summer conducting in vivo hemostatic and infected wound healing tests using a mouse model to evaluate the rapid and effective hemostatic properties of the designed hemostatic agent, as well as its ability to promote the infected-wound healing.

With a Bachelor’s degree in Chemical Engineering from India and my commitment to never stop learning, the journey of my Master’s degree in Chemical Engineering began in August 2017 at Michigan Technological University (MTU). My passion and eagerness to learn new things led me to work voluntarily on multiple sustainability-related research projects during my Master’s degree, which also helped me in earning a Graduate Certificate in Sustainability in 2019. I soon realized that there are still a lot of things to explore and learn more about while contributing my efforts to ensure a sustainable world. With this idea in mind, the journey of my PhD in Chemical Engineering started in the Summer of 2019 in Dr. David Shonnard’s research group.

As a part of my research, we developed a systems analysis framework to identify the major plastic supply chain processes starting with production of plastics to the end-of-life management of waste plastics in the U.S. Furthermore, it expands on evaluating and optimizing the supply chain processes to minimize the environmental impacts such as greenhouse gas emissions and energy consumption of the entire system. My research also identified different types of commercially existing and newly emerging advanced or chemical recycling technologies for waste plastics and estimated their environmental and economic feasibility to compare against fossil-based traditional technologies that produce plastics. Additionally, our research also addressed the socio-economic impacts such as employment, revenues, and annual wage generation across the entire plastic supply chains due to increased recovery and recycling of plastics. I am incredibly grateful to work with various collaborators from national laboratories, industry partners, and different universities.

First, I would like to extend my gratitude to the Graduate Dean Awards Advisory Panel for recommending me for this prestigious award. I also want to acknowledge the department of Civil, Environmental, and Geospatial Engineering for its support during my PhD studies. Most importantly, I thank my advisor Dr. Daisuke Minakata, who has guided me throughout my journey and equipped me with critical thinking skills. Without his unwavering commitment, understanding, and guidance, I would not have achieved the level of proficiency as a PhD student that I possess today.

I have been passionate about chemistry ever since I was in high school. Chemistry teaches you how matter transforms, and because matter is everything we are surrounded by, chemistry essentially helps you to understand the world. Many of the big problems our world faces can be tackled in some way from a chemical perspective. Energy, pollution, water scarcity, health, are some of the global issues that are actively being addressed with chemistry.

During my PhD, I have translated my chemistry background to the environmental engineering field by understanding how pollutants are transformed in natural and engineered water systems, such as lakes, rivers, or water treatment plants. My philosophy is that the molecular details of those chemical reactions have a profound influence on the rate of degradation and products distribution. This led me to publish papers where I show that we can use results from molecular simulations to explain phenomena at the bulk scale such as how fast reactions take place. Understanding these details will enable engineers to optimize operational parameters on the removal of contaminants, and will inform environmental policy makers about the fate of toxic compounds once released to bodies of water.

Doctoral Finishing Fellowship – Fall 2023 Recipient – Hrishikesh Gosavi

Since I began learning the basics of science, the effects of vibrations on environments has always fascinated me. As Nikola Tesla said, “If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” It was with this aim that I started my Ph.D journey in Fall 2020.

My research has been in regards with “Metastructures”. These are unique structures which absorb vibrations in a system in particular frequency range, often called as ”bandgap”. It is because of this bandgap phenomenon that metastructures are widely used to mitigate vibration effects. Owing to large number of applications, it becomes important to estimate bandgaps in a metastructure to predict the frequency range in which the vibrations will be absorbed so that metastructures can be designed for various applications.

Through my research, I have aimed to developed new methods to estimate these bandgaps. The current methods available in the literature require a physics-based model of the metastructure (analytical model, finite/spectral element model) in order to estimate bandgaps. However, for various anisotropic materials, the material properties are difficult to quantify accurately which makes the physics-based model inaccurate. My research aims to overcome these limitations by developing methods which estimate bandgaps using purely experimental data. We have used the experimental data to study how a vibration wave is propagating through the metastructure (dispersion curve) and estimated bandgaps. Various other techniques such as substructuring, data-driven modeling algorithms were utilized. The developed techniques considerably reduced the design efforts required and made the entire design process much easier.

The funding provided by this fellowship will truly be helpful for me in putting all my energies in finishing my thesis in time and complete my Ph.D.!
I am grateful to the Graduate School for granting me this fellowship.
My advisor, Dr. Sriram Malladi has been more than helpful in guiding me through various ups and downs throughout my Ph.D journey. I am truly thankful for the relentless support he and his family has given me. Last but certainly not the least, I am thankful to my family i.e. my wife and my parents for their support in every aspect of my journey!

Growing up in a township full of scientists and engineers, I have always been curious about how things work. This led me to pursue a bachelor’s in engineering from Nehru Institute of Engineering and Technology affiliated with Anna University, Chennai. I then pursued a master’s from the esteemed Indian Institute of Technology, Madras where I delved into diverse research projects that captivated my interest. Fueled by this newfound interest, I started my journey as a Ph.D. student eager to tackle intriguing and fundamental challenges within the field of engineering.

I started working on my Ph.D. in the Fall of 2019 at the Computational Mechanics and Machine Learning Lab led by Dr. Susanta Ghosh at Michigan Tech. The focus of my research is on understanding the uncertainties associated with the predictions of computational and machine-learning models. Any model, computational or data-driven, is a representation of a physical phenomenon. We develop such models to understand the world around us better. However, predictions of such models are not always reliable due to the uncertainties associated with them. These uncertainties could arise for various reasons such as natural variability in the systems we study, assumptions in developing these models, numerical approximations, lack of data, etc. In order to use these models in real-life scenarios, quantifying these uncertainties is crucial. My research involves developing novel techniques to quantify the uncertainties, use these uncertainties to improve the model’s performance, and explain the reasoning behind the uncertainties. In my first project, we developed a Bayesian neural network-based machine-learning model that can reliably classify breast histopathology images into benign and malignant images. In addition, the model can quantify uncertainties associated with the predictions. We further developed techniques to explain the uncertainties and use them to further improve the model’s performance. In my second project, we developed novel loss functions for Bayesian neural networks and showed their advantages over the state-of-the-art in image classification problems. I am currently working on quantifying uncertainties in computational models that are used to characterize material behavior and extending the first two projects for several other applications.

I would like to thank my advisor Dr. Susanta Ghosh for giving me the opportunity to carry out this exciting research as well as for his immense help and guidance throughout the process. I thank the Graduate Dean Awards Advisory Panel and the dean for recommending me for this award. It is an honor. I thank the graduate school and the Department of Mechanical Engineering-Engineering Mechanics for their constant support.
