Katrina Velle, PhD

Profilie_picture_edited.jpg

Katrina Velle is a cell biologist interested in cytoskeleton-driven phenotypes and pathogenic microbes. She is investigating the contributions of actin networks to cell migration, cell division, and osmoregulation in Naegleria, including the “brain-eating amoeba.”  She received her PhD in Molecular and Cell Biology from UConn in 2018, and worked with Dr. Fritz-Laylin at UMass Amherst for her postdoctoral research. She is now an Assistant Professor of Integrative Biology at UMass Dartmouth. Her work has been supported by an NIH F32 fellowship (NIAID), an NIH K99/R00 Award (NIGMS), and Amazing Aven's Quest for Amoeba Awareness.

Abdurrahman ElZafarany

Abdurrahman ElZafarany is a PhD student in Katrina's lab. Abdurrahman did his bachelor's at Carnegie Mellon University (2020) and moved on to get his Master's at the University of Pécs (2023). His main areas of interest are Molecular Biology as well as a tad bit of Immunology. He's interested in learning how Naegleria fowleri cells crawl in confined spaces, particularly the brain, and how they use actin to do so. Understanding how disease is initiated and spread can help provide insights into treatment later on.

Tara Clark

Tara Clark is a lab manager and cell culture specialist in the Velle lab interested in infectious disease and immunotherapy development. She received her Master of Science degree in Biology from UMass Dartmouth in August 2024 with Dr. Bromage’s comparative immunology lab. Her research investigated the antibody-mediated immune responses to different bacterial vaccine combinations given to rainbow trout in an aquaculture environment. Tara joined the Velle lab in September 2024 and is excited to explore the behavior of Naegleria fowleri and their use of actin when grown in co-culture with mammalian cells. She also plans to evaluate the potential for use of Naegleria-specific actin inhibitors in preventing these infections.
