Mentoring Style
One of the primary reasons I sought out a career in academia was the opportunity to work with and mentor students. As a research advisor, I am here to challenge the students while also providing them with a nurturing environment for learning and growth. I have been extremely lucky so far in that I have recruited and retained some exceptional students (you can find their bios here) that have helped create/maintain this environment. A big focus of mine is translatable skills, so students can pivot if they become interested in another field or sector after graduation. I also believe in collaborative research, so I ask my students to work together on supplementary efforts to share knowledge and grow their skillset. In doing so, the student hopefully gain a complete perspective of what it takes to be successful in a career in research, which is ultimately the goal of academia: to train the future workforce.
Research Areas
Previous research experience and current research interests include the following areas:
Thermo-mechanical finite element (FE) modeling is a focus for additive manufacturing (AM) and understanding the role of the thermal history as it pertains to the resultant mechanical response of an additively manufactured component.
Structure-property modeling is used in an effort to extract high-level knowledge from experimental or computational datasets in an effort to connect microstructure-level information (e.g., grain size, morphology, texture) to macroscopic properties (e.g., yield strength and ductility).
The inductive design exploration method (IDEM) is a type of optimization modeling that instead seeks out robust solutions utilizing the top-down or performance-driven approach for materials and engineering applications.
Materials of Interest
Metallic Systems including Ti-6Al-4V, Inconel 718, 250 maraging steel, 316 stainless steel, and magnesium alloys
Intermetallics including Mo-Si-B alloys
Geomaterials such as cementitious materials like ultra-high performance concrete (UHPC)

Hometown: Picayune, MS
Research Topic: Computational Modeling of Additive Manufacturing Parts and Processes
Why did you choose this research field/discipline for graduate research? During my undergraduate in mechanical engineering, I had the opportunity to co-op with a company in R&D. During my tenure, I was exposed to several problems that required an understanding of how microstructures evolve under varying mechanical, thermal, and even chemical loads. As an undergraduate preparing for industry, we learn how to design parts with safety factors to prevent failure. However, I became too curious and chose to pursue mechanical engineering in graduate school to learn why parts fail to reduce the need for a safety factor.
What do you want to do with the PhD when you complete your degree? I aim to use the skills I acquire from my PhD with the Engineering Research Development Center in Vicksburg, MS to help develop protective equipment for our nation's bravest. My experience with computational modeling and associated skill sets will help to develop more efficient equipment, while also finding ways to use new materials to push the envelope of what we can currently do.

Research Topic: Fire forensic analysis of aerospace composites
Why did you choose this research field/discipline for graduate research? Fire forensic analysis of structural aerospace composite members presents an important aspect of an overarching root-cause analysis of failure of aerospace parts during a crash event. The aim of the research is to develop a protocol for failure characterization and fire-damage assessment of aerospace composites by creating a novel surface cleaning protocol to remove char and examine the underlying failure characteristics. The end goal of the research efforts is to update the existing composite failure analysis methods to account for fire damage and refreshing the FAA failure analysis handbook.
What do you want to do with the PhD when you complete your degree? I would like to continue my research efforts on topics of interest (additive manufacturing, composites) as a post-doctorate researcher.

Research Topic: Single bead wire arc DED printing process
Why Engineering? I chose engineering because I grew up in a very technical, hands-on environment while working on our family farm with my dad, who was previously an engineer, from a young age. I was constantly surrounded by machinery and mechanisms and saw my dad create his own/ adjust current systems, which created a longing in me to figure out how they worked. That curiosity led me to the Mechanical Engineering Department here at Mississippi State University, where I have expanded my knowledge on a broad range of engineering and technical topics, and I look forward to all of the knowledge I have yet to obtain.
Why this specific research topic? I chose this research because I have experience in smaller PLA 3-D printing, and having used it on a small-scale level, I can see the potential this process has that can be accessed by researching the different processes
