Welcome back to Tampa for Sanjib, who recently completed an NSF-sponsored summer internship at Sonavex, a startup biomedical device company in Baltimore, MD. At the internship, Sanjib performed benchtop experiments and CFD simulations of an arteriovenous fistula. He also was able to explore sites along the East Coast, including the Steven F. Udvar-Hazy Center in Virginia (below), which is part of the Smithsonian National Air and Space Museum.

Dr. Murphy traveled to Palmer Station, Antarctica to research krill schooling behavior in collaboration with Dr. Marc Weissburg and Dr. David Fields. We collected photogrammetric measurements of krills swimming in groups in a specialized flume and took high speed videos of individually swimming krill.
Rubbing or kissing Magellan's toe supposedly ensures smooth sailing on Drake's Passage. It didn't work for me!
October 22, 2019

August 30, 2019
The Murphy Lab had a Back-to-School Party to celebrate the start of a new semester. Highlights included fluids-inspired charades and making ice cream!
July 18, 2019
The Murphy Lab is headed to Antarctica! We were just awarded a new grant from the National Science Foundation to investigate the collective behavior of Antarctic krill. The award is from the Office of Polar Programs and is titled "Collaborative Research: Individual Based Approaches to Understanding Krill Distributions and Aggregations." We will be working with Marc Weissburg at Georgia Tech and David Fields and Nick Record at Bigelow Laboratory for Ocean Sciences. Dr. Murphy and PhD student Kuvvat Garayev will perform this research at Palmer Station in the Nov-Dec time frame of 2019, and Kuvvat will return in 2020 to complete the experiments.
May 13-19, 2019
PhD student Kuvvat Garayev, undergrad Josh Arandia, and Dr. Murphy visited our collaborator Amy Maas at the Bermuda Institute of Ocean Sciences to continue our research into sea butterfly swimming, to work with Amy and artist Samm Newton on creating a children's book about sea butterflies, and to work with collaborator Margaret Byron on metachronal swimming by ctenophores. It was our fifth trip to BIOS. We collected some great data on the kinematics and hydrodynamics of various sea butterfly species and made some good progress on the children's book, but, unfortunately, no ctenophores were to be found!

October 14-19, 2018
Dr. Murphy and Ferhat Karakas visited our collaborator Amy Maas at the Bermuda Institute of Ocean Sciences to research sea butterfly swimming. We collected data on the kinematics and hydrodynamics of sea butterflies. It was our fourth trip to BIOS. The weather cooperated with us reasonably well at the beginning of this trip, and we were able to collect animals three times for experiments. High winds kept us on land towards the end of the trip, so we visited a flooded underground cave system!

September 13-15, 2018
Dr. Murphy's Biological Fluid Mechanics class and lab group took a class trip to visit the Keys Marine Lab in Layton, FL. We had a guest lecture from Dr. Aditya Nayak of FAU about particles in the ocean, went on a snorkeling trip to see the various swimming modes we had discussed in class, and used micro-Particle Image Velocimetry to look at how copepods swim. Thanks to the Florida Institute of Oceanography for supporting this educational experience through a shiptime proposal!
May 8-22, 2018
Dr. Murphy, Ferhat, Ali, and Daniel traveled to the Bermuda Institute of Ocean Sciences (BIOS) to again work with collaborator Dr. Amy Maas and to begin work with Dr. Margaret Byron at Penn State and Dr. Damian Grundle at BIOS. We worked on several projects using the unique access to 'critters' that BIOS offers. We studied the propulsion of various sea butterfly species using a cutting-edge, high speed particle tracking velocimetry system (Shake-The-Box PTV - Thanks to LaVision for loaning us the software!). We also studied metachronal swimming in ctenophores and mantis shrimp and began preliminary experimental lab work on how oil slicks may affect air-sea gas transfer under the influence of rainfall. It was a jam-packed two weeks!
