2025 OSSP Speakers

Title: TBA

Dr. Kate Fenwick
Research Associate at the National Research Council of Canada (NRC)

Abstract: TBA

Bio: Kate is a Research Associate, holding a Luise and Gerhard Herzberg Fellowship, at the National Research Council of Canada (NRC) in the Ultrafast Quantum Photonics group. She very recently completed her PhD studies in physics at the University of Ottawa, where she held a Vanier Scholarship. Prior to her PhD, she completed her BSc and MSc at Queen’s University, also in physics. Kate’s primary research interests lie in the field of ultrafast quantum photonic technologies, with a focus on ultrafast photonic quantum information processing. Outside of the lab, she can often be found trail running, swimming, or cross-country skiing in Gatineau Park (depending on the season). She is very excited to meet the students at OSSP!

Title: TBA

Dr. Joseph Mastron
TOPTICA Photonics

Abstract: TBA

Bio: Joseph Mastron, Ph.D. works for TOPTICA Photonics at the North American branch in Rochester, NY, as a Product Manager for Optical Isolators and Biophotonics Applications Scientist. He earned his Ph.D. in Physical Chemistry from the University of Chicago, where he developed novel multidimensional spectroscopic techniques combining infrared excitation and visible fluorescence detection. He continued his research as a postdoctoral fellow at the University of Michigan, joint between Chemistry and Physics departments, applying ultrafast laser methods across UV, visible, and IR regimes to study energy transfer in photosynthesis and catalysis.

Throughout his career, Joseph has combined technical depth with leadership and service, including serving as Copresident of the UM Postdoctoral Association, organizing science communication workshops with the local CommSciCon-MI chapter, and co-chairing the Biomedical Applications subcommittee for CLEO. Today, he bridges research and industry, helping researchers achieve their research goals with cutting-edge laser systems while simultaneously managing a high-value product line of laser components.
