Savannah Horowitz
B.S. Materials Science and Engineering (with certificate in metallurgy); University of Florida, 2023
Savannah is from Auburndale, FL. She received her B.S. in Materials Science and Engineering with a certificate in Metallurgy from the University of Florida in Gainesville, FL. While there, Savannah was a part of Phi Sigma Rho, Machens First Opportunity Scholars, and participated in a study abroad program to Madrid, Spain. During her undergraduate career, Savannah conducted research focusing on high entropy memory shape alloy development and automation of infrared thermography non-destructive testing image analysis for welds. Savannah presented her undergraduate research at the TMS 2022 conference, where she won first place in the Undergraduate Materials Processing & Manufacturing Division. She also has experience in industry, working on the processing of stainless steels at Tesla. Savannah's current project focuses on studying the corrosion-fatigue properties of Al-alloys. Savannah likes to spend her free time cooking, rock climbing, and embroidering.
Savannah's research currently focuses on utilizing modeling techniques to predict cyclic corrosion in accelerated atmospheric corrosion chambers. Her work involves the application of finite element method (FEM) modeling and analytical modeling approaches.
Timothy (TJ) Montoya
B.S. Chemistry; University of New Mexico, 2022
Timothy was born and raised in Albuquerque, New Mexico where he earned his BS degree in Chemistry with a Distributed minor at the University of New Mexico. During his undergrad, Timothy worked as a year-round research and development student intern at Sandia National Labs. His research focused on studying corrosion problems for the spent nuclear waste program. Outside of school and research, Timothy enjoys going to the gym, participating in sports, hanging out with friends, and playing video games.
With the rise of additive manufacturing (AM) around the world, Timothy’s work investigates the influence of AM processes and processing conditions on the microstructure and corrosion behavior of various materials such as stainless steels and copper nickel alloys. This work couples the use of various electrochemical and characterization techniques to continue to improve the AM processes and better understand the use of AM in place of traditional manufacturing processes.
Armando Shehi
B.S. Chemical Engineering; California State Polytechnic University Pomona, 2021
Armando was born and raised in Albania and later moved to United States where he obtained a BS degree in Chemical Engineering with a minor in Materials Science and Engineering. During his undergraduate time, Armando conducted research on the corrosion behavior of novel metallic alloys for biomedical applications. His area of research later expanded to investigating and comparing the corrosion behavior of various AM alloys for biomedical and marine environments. Armando’s free time is spent between creating and exploring new dishes and learning languages.
Armando's research investigates pitting corrosion of spent nuclear fuel (SNF) canisters under complex aqueous environmental conditions. It employs cutting-edge electrochemical methods, combining modeling and experimental techniques, to understand the intricacies in kinetic parameters of pit propagation in various salt compositions, temperatures, and humidity levels. The goal is to develop and verify a comprehensive and practical predictive model for maximum pit sizes and shapes that can form under specified environmental conditions.
Victor Kontopanos
B.S. Chemistry and Engineering Physics; Randolph-Macon College, 2021
Victor is from Richmond, VA. He received his B.S. in Chemistry and Engineering Physics with a minor in Physics from Randolph-Macon College in Ashland, VA where he participated on the R-MC Men’s Swim Team for NCAA Division III. During his undergraduate career, Victor performed research in the Chemistry department that focused on the synthesis of nickel phosphide nanoparticles for electrocatalysis of the hydrogen evolution reaction. Victor also has experience as a laboratory teaching assistant for inorganic chemistry at R-MC and as an engineering sciences intern for Afton Chemical Corporation. In his free time, Victor likes to play board games, read a variety of books, rock climb, and spend time with his friends and family.
