Lead Network Engineer • bhaley @

Ph.D. (2005) University of California, Davis, Engineering Physics/Applied Physics
B.S. (1998) Purdue University, Physics

I am the Lead Network Engineer of the IN-MaC project at Purdue.  I develop the Technical Cost Modeling (TCM) software tools used in the Mansson research group.  I also work on digital integration of TCM and Industry 4.0 software tools for the analysis of manufacturing data produced in the IN-MaC Digital Manufacturing Testbed.

I previously worked as a senior software engineer in Research Computing at Purdue, developing scientific simulation software and middleware tools for nanoHUB. Most of my career has been spent at universities, but I spent two years in industry, at Cummins Engine Co. in Indiana and Intel Corp. in California. I received a BSc in physics from Purdue, followed by a MSc and Ph.D. in applied physics from the University of California, Davis.

A.S. (2013) Vincennes University, Precision Manufacturing

I joined Purdue in January of 2020 as the Sr. Engineer of IN-MaC’s testbed. IN-MaC is co led by prof. Mansson. My duties are in connection with subtractive manufacturing as it pertains to lab research, and work engaging IN-MaC affiliates. I work on a number of projects that include Prompto-Typing™, IOT machine sensor/monitoring, and also Industry manufacturing consultation. Prior to joining Purdue, I worked at various companies in the region as a CNC programmer and toolmaker. Among these companies are TMF center, Marion Manufacturing, and Caterpillar LEC. In my free time, I enjoy training horses, hunting, and general farm life.

B.S. (2015) Purdue University, Mechanical Engineering

M.S. (2017) Purdue University, Aeronautical and Astronautical Engineering. “Informing Hybrid-molded Composite Performance Using Manufacturing Process Simulation”

I am a Ph.D. Student in the Purdue University School of Aeronautics and Astronautics.  My research interests center around design and manufacturing of unidirectional tow reinforced hybrid composite structures for high rate, low cost production of structural thermoplastic composites with the goal of developing design guidelines from simulation and experimental approaches.  My other projects include application of hybrid composite structures to real-world automobile components and sports equipment.  I am also an avid mountain biker and cyclocross racer with the Purdue Cycling Club which sparked my interest in composite materials. 

Teal Dowd

Graduate Research Assistant • dowdt @

B.S. (2018) Purdue University, Mechanical Engineering

Teal Dowd is a Materials Engineering Ph.D. student at Purdue University. His research focuses on new methods of selective laser sintering leveraged to combine continuous fiber within a polymer matrix. With a love of getting his hands “dirty”, this hands on project is combining mechatronics, electrical, computer, and materials engineering into a single project. Dowd received his undergraduate degree in mechanical engineering from Purdue in 2018, and transitioned directly into a Ph.D. program working with Dr. Mansson in the MD Lab. When he is not in the lab tinkering, Dowd enjoys adventuring in the outdoors including rock climbing, and DIY home improvement projects.

Graduate Research Assistant • jlavorat @

B.S. (2018) Winona State University, Composite Materials Engineering

I began pursuing a PhD in Materials Engineering under Dr. Jan-Anders Mansson in August 2018. My research focuses on the high-rate manufacturing of multifunctional thermoplastic composite rods (M-TOW) which can be deformed via a die-less multi-axis forming machine. This includes manipulating process parameters to acquire an ideal processing window that relies on temperature, line speed, and braid pressure. The goal of the work is to manufacture a preform with a constant cylindrical cross-section that can act as a transfer medium for various components such as air tubing, sensors, or electrical wires, in addition to having the ability to be overmolded for advanced light-weight applications. In my free time, I enjoy exploring the outdoors through camping, hiking, paddling, and rock climbing.

Anna Giesler

Graduate Research Assistant • giesler @

B.S. (2020) Purdue University, Materials Science and Engineering

I am a second year Ph.D. student joining the MD lab. My research will focus on sensor integration and digital technology in sports to enhance athlete performance and fan experience. In 2020, I received my undergraduate degree from Purdue University in Materials Science and Engineering. While attending Purdue, I was member of the varsity swim team for four years. During Summer 2018, I began my research career with Dr. Mansson where I investigated fabric orientation, inter-yarn porosity, and level of stretch on the permeability of technical swimsuits. That Summer experience combined my passion for sport & engineering, which ultimately led me to pursue a graduate degree with Dr. Mansson. In my free time, I love to travel, be on the water and the beach, and read a good book.

Morgan Chamberlain

Graduate Research Assistant • chamb111 @

B.S. (2020) Linfield University, Physics

B.S. (2020) Linfield University, Mathematics

Morgan is a third year PhD Candidate in Materials Engineering. An Oregon native, Morgan graduated from Linfield University in 2020 with two Bachelor’s degrees in Physics and Mathematics. She also competed as a javelin thrower for the track & field team while at Linfield. Morgan’s research centers around the reliability of recycled carbon fiber reinforced composites for new sports engineering and automotive applications. She is also the current Vice President of Purdue’s Materials Engineering Graduate Student Association (MSEGSA). In her free time, Morgan enjoys power lifting, reading, painting, and hiking through the Pacific Northwest.

B.S. (2016) Seoul National University, Mechanical and Aerospace Engineering

M.S. (2018) Seoul National University, Aerospace Engineering

I joined Purdue University as a Ph.D. student in Aeronautics and Astronautics Engineering in 2021. My research interests include analysis and manufacturing processes for advanced composite materials with industrial applications. During my Master’s program at Seoul National University, I conducted research on piezoelectric multilayer composite laminate structures under various environments with deformation simulations. In my free time I enjoy reading and learning to cook.
