Research Interests

My research centers on water quality and how that affects microalgal communities (phytoplankton, periphyton, epiphytes etc.). Within this context and beyond, I study photosynthetic and accessory pigments (chlorophylls, carotenoids, scytonemins, phycobilins). Pigment-based chemotaxonomy, the use of taxon-specific biomarkers to discern community structure and dynamics, is a main thrust in my research as well. Lately, I have been very involved in studying phosphorus pollution of south Florida waters from the overuse of equestrian waste in agri-businesses. Global climate change, especially rising carbon dioxide levels, is also studied as it impacts microalgal communities in both marine (“ocean acidification”) and fresh waters.

Community outreach

Each year I represent the University and specifically the College of Science and the Environmental Sciences Program at the Lake Worth Lagoon Fest. This event is a community-wide outreach event which highlights the environment of Lake Worth Lagoon, its opportunities (fishing, boating, nature studies etc.) and its rejuvenation.

In 2016 south Florida experienced several cyanobacterial (aka “algal”) blooms and I provided information to the public through numerous media interviews (CBS,NBC, National Public Radio, Channel 5 (WPTV),WPTC-FaceTime, Palm Beach Post and others.
