On October 25th and 26th, 2023, the REMADE Institute held a meeting in Rochester, NY, for its members. During the meeting, Anthony Cardinali and Valeria Marin-Montealegre, second-year Ph.D. students at the iMED Lab, presented a poster on "Development of Hybrid Repair and Nondestructive Evaluation Technologies for Aerospace Components."
Our Ph.D. students have returned to campus after the summer break!
It is essential to acknowledge the remarkable work they have carried out during their summer internships at different companies and universities across the United States. Their knowledge and skills in research and development are contributing to the development of science in their respective focus area.
Learn a little more about our Ph.D. students and their experiences below.
Valeria Marin-Montealegre did her internship at the Center for Medical Technology & Innovation (CMTI) in the Department of Biomedical Engineering, University of Rochester, during the summer of 2023.
As part of the CMTI summer clinical rotation program, she had the opportunity to work alongside CMTI students in various operating rooms at Strong Memorial Hospital, including general surgery, cardiac surgery, OB/GYN, ENT, neurosurgery, and orthopedics. Her primary responsibility was to identify the needs of the different medical teams and patients and translate them into potential medical devices.
Likewise, she was conducting workshops on additive manufacturing and digital flow for medical modeling to help clinical students generate personalized medical products.
Maria Camila Ceballos-Santa was doing her internship at Genentech, founder of the biotechnology industry and member of the Roche Group since 2009.
She was immersed in the scope of product development, with a specific focus on the Clinical Sciences domain. She enriched her understanding of late-stage studies while collaborating with global cross-functional teams on everything necessary to ensure the safety and efficacy of a drug that could be marketed for patients suffering from severe and life-threatening illnesses. Beyond this, she has had the privilege of contributing to projects aimed at promoting diversity and inclusion initiatives within the field of research, with the vision of improving outcomes in different demographic populations.
Among her responsibilities were:
- Assist in the review of critical documents related to late-stage clinical trials.
- Assist with data review of late-stage clinical trials.
- Develop/provide input for clinical presentations.
- Participate in global cross-functional team discussions on medication safety and efficacy.
- Assist with strategic project initiatives that evaluate various areas of clinical trial development to improve diversity and inclusion and report findings.

June 1, 2020 - Congratulations are in order for Emily Lazarus, Melvin Cruz, and Samantha Sorondo.
Ms. Lazarus completed her bachelor's in BME and got accepted into the RIT PhD program. Mr. Cruz completed his bachelor's in Electrical Mechanical Engineering Technology. Ms. Sorondo successfully completed her Qualifying Exam, an important milestone in the RIT PhD program.
March 16, 2020 - Dr. Iris V. Rivero published a paper titled "Effect of Pre‑welding Heat Treatment on the Mechanical Properties of Friction Stir Welded Al–4wt.%Cu Alloys"
Ref: Al-Dwairi, A. F., Abdelall, E., & Rivero, I. (2020). Effect of Pre-welding Heat Treatment on the Mechanical Properties of Friction Stir Welded Al–4 wt.% Cu Alloys. Metallography, Microstructure, and Analysis, 1-11.
February 27, 2020 - Srikanthan Ramesh and Dr. Iris V. Rivero published a paper titled Process–Structure–Quality Relationships of Three-Dimensional Printed Poly(Caprolactone)-Hydroxyapatite Scaffolds in the Journal of Tissue Engineering Part A. The article frames a systematic approach for the optimization and validation of 3D printed scaffolds. They studied printing process parameters (e.g. temperature, extrusion temperature, etc.) and performed different tests to establish the mechanical properties of the printed scaffold. Additionally, they demonstrated that small defects, such as voids, negatively affect printed polymeric scaffolds.
This paper was the product of a collaboration of iMED (RIT), LIMB lab (UConn), and Prahalad Rao (UNL).

October 15-17, Detroit MI - Jakob Hamilton presented iMED Laboratory research at the Heat Treat Conference. This work, a collaboration between iMED Laboratory and AMPrint Center at RIT, sought to study the effect of process parameters on the printed piece's density. Components were fabricated using a state-of-the-art hybrid manufacturing machine in the Brinkman Machine Tools and Manufacturing Laboratory, and applied laser power and scanning speed were found to directly influence metal characteristics.
August 2019 - iMED Laboratory Research Assistant and RIT graduate student Jakob Hamilton was recently awarded the E. Wayne Kay Graduate Scholarship for Masters students for his ongoing thesis research into metal alloys and composites for 3D printing.

Hamilton would also like to thank his research advisor Dr. Iris Rivero and colleagues Srikanthan Ramesh and Samantha Sorondo for their support and encouragement throughout the research process.
August 13, 2019, Austin TX - Jakob Hamilton presented iMED Laboratory research in 5-axis hybrid manufacturing at the Annual International Solid Freeform Fabrication Symposium in Austin, Texas. This work, a collaboration between iMED Laboratory and AMPrint Center at RIT, sought to unveil challenges with 3D printing stainless steel on non-planar surfaces. Components were fabricated using a state-of-the-art hybrid manufacturing machine in the Brinkman Machine Tools and Manufacturing Laboratory, and applied laser power and scanning speed were found to directly influence metal characteristics.
