Sumit joined the Mote Phytoplankton Ecology group in February 2018. Sumit is interested in fine scale phytoplankton dynamics and the role of phytoplankton in the ocean carbon cycle and quantitative understanding of the perturbations by climate change and human activities on phytoplankton dynamics in the coastal oceans. He takes an interdisciplinary approach in his research, using a combination of bio-optics, remote sensing, HPLC pigment analysis, phytoplankton cell counts, statistical modeling, and laboratory- based experiments.
At Mote, Sumit is working on multi-station time series of phytoplankton data in the West Florida shelf to study the time-varying changes in phytoplankton community (inter-group/inter-functional types variability). He is also involved in designing laboratory experiments to address specific question on Karenia brevis physiology and trophic level interactions.

We are tremendously thankful that Mote Aquarium will be able to reopen to the public on Saturday, October 1, during normal operating hours (9:30 AM - 5:00 PM), following our closure for preparation and response to Hurricane Ian. Unfortunately, our Sharktoberfest event, which was scheduled for October 1, will be postponed. If you have purchased a ticket, please check your email for more information. Our thoughts and best wishes are with our friends, family, partners and all of those who are continuing to manage recovery efforts. Any additional updates about reopening will be provided via social media: @MoteMarineLab on Facebook, Instagram, Twitter.
