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! 

April 11 & 22, 2019

Dr. Murphy gave a seminar in the Mechanical Engineering Department at Penn State University in early April (hosted by collaborator Dr. Margaret Byron) and a seminar in the Mechanical Engineering Department at Virginia Tech (hosted by collaborator Dr. Olivier Coutier-Delgosha) in late April. It was great to share our work on sea butterfly swimming and tiny insect flight and to see the great work being done in their departments (and to get ice cream at the world-famous Berkey Creamery!). 

February 17, 2019

Ali and Ferhat attended the Clearwater Marine Aquarium Marine Science Fest to tell people about the research we are doing on sea butterflies. They also demonstrated a high speed video camera system to visitors.

February 6, 2019

Dr. Murphy is awarded a CAREER grant from the National Science Foundation! The award is from the Fluid Dynamics program and is titled 'CAREER: Aerial and Aquatic Flapping Flight at Low Reynolds Numbers." This grant will allow the Murphy Lab to continue investigating flapping 'flight' by swimming sea butterflies and to begin investigating the flight of tiny insects.

February 3-7, 2019

Carlowen Smith and Dr. Murphy traveled to New Orleans to attend and present at GOMOSES, the Gulf of Mexico Oil Spill and Ecosystem Science conference.

January 10-17, 2019

Ferhat Karakas and Dr. Murphy traveled to Canada to attend and present at the 5th Microscale Ocean Biophysics meeting in snowy Whistler, B.C. 

December 21, 2018

We had our second annual lab holiday lunch! Petra Restaurant did not disappoint!

December 7, 2018

We published our first paper which is entirely a product of the Murphy Lab. Congrats to Ferhat for his new paper in the Journal of Experimental Biology, titled 'Using a shell as a wing: pairing of dissimilar appendages in atlantiid heteropod swimming!' The paper was featured with a writeup in Inside JEB as well!

November 18-20, 2018

The Murphy Lab traveled to Atlanta, GA for the 71st Annual Meeting of the American Physical Society Division of Fluid Dynamics (APS DFD). It was a great conference. The opening reception was held in the Georgia Aquarium, and everyone's presentations went well.

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!

May 1-2, 2018

Sanjib and Dr. Murphy visited collaborator and developmental biologist extraordinaire Ben Dubansky at the University of North Texas. We spent two days taking high speed footage of the blood flow in embryonic Gulf Killifish as we investigate how exposure to crude oil affects their physiology. Thanks to Ben for the tweet!

Feb 19, 2018

Daniel Olsen and Dr. Murphy visited the Clearwater Marine Aquarium Marine Science Fest to tell folks about our work on sea butterfly swimming. It was great to show our high speed videos to the public, educate people about these amazing little critters, and represent USF!

Feb 16 , 2018

It's been a busy two weeks of travel! Dr. Murphy attended the Gulf of Mexico Oil Spill and Ecosystem Science (GOMOSES) conference in New Orleans and then traveled to Portland, Oregon to present work on sea butterfly swimming at the 2018 Ocean Sciences Meeting.

Dr. Murphy and graduate student Ferhat Karakas just returned from a second research trip to the Bermuda Institute of Ocean Sciences. Working with Amy Maas, we collected data on the swimming of ctenophores, mantis shrimp, and various pteropod species. We also were joined by our NAKFI-sponsored artist-in-residence, Samm Newton, who is creating art to help interpret our data for the public. Samm also took some great photos of the research trip.
