My research interests are focused around galaxy evolution and star formation in galaxy groups and clusters. I am an observational astronomer and use multiwavelength observations to constrain the physical mechanisms responsible from transforming galaxies in dense environments.
Here are some current projects which I am actively involved in:

• Identifying Jellyfish Galaxies with the LOFAR Two-metre Sky Survey
• VERTICO: The Virgo EnviRonment Traced In CO
• Ram Pressure Stripping in Wide-Field Optical Surveys (UNIONS)
