Sarah J Wolff

Assistant Professor, Industrial and Systems Engineering

wolff@tamu.edu

Dr. Sarah Wolff focuses on additive manufacturing of metallic and composite materials. She completed her PhD in mechanical engineering at Northwestern University in 2018 with her thesis work on understanding the directed energy deposition additive manufacturing process. For the following year, she was an Enrico Fermi fellow at Argonne National Laboratory where she built a directed energy deposition system and used high energy X-rays at the Advanced Photon Source to monitor laser-matter interactions in real time. As a life-long Chicagoan, Dr. Wolff is excited to join the Aggie family.

Masters Students

Karan Kankaria

karan@tamu.edu

Karan’s research interests include studying the size distribution of porosity in Laser-assisted Direct Energy Deposition of metals. He is currently looking into the correlation between laser energy input, powder flow rate and powder shape with the final porosity size distribution. He is pursuing his Master’s in Industrial Engineering at Texas A&M University, College Station.

Karlie Nixon

kbnix15@tamu.edu

Karlie’s research interests include predicting and characterizing porosity in powder bed fusion additive manufacturing. She plans on applying this research to her thesis, focusing on porosity in 3D-printed implants. Her expected graduation is in 2022 with a master’s degree in Industrial Engineering – Health and Human Systems.

Undergraduate Students

Nihar Patel

nhp_300@tamu.edu

Nihar’s research interests include metal additive manufacturing as well as thermo-fluid analysis. His current work includes developing a DED powder deposition nozzle. He plans on graduating in Spring 2021 with a B.S. in Industrial Engineering.

Ron Sellers

ronsellers@tamu.edu

Ron’s research interests include additive manufacturing processes in optimization of material, developing increased structural integrity, and keyhole and porosity data analysis. His current project is on IR and X-Ray image processing to observe how the particles are reacting to the heat of the laser. His anticipated graduation date is May 2022.
