Leftwich Lab news, hot off the press


 

NY Times Summer of Science 

The NY Times has a great, visually driven series this year called the Summer os science. The excellent Nicholas St. Fleur wrote a great piece on our Sea lion work. It’s a nice short explanation of what we do at the National Zoo.


Smithsonian Magazine video! 

Check out this great video on our work with the California sea lions at the National Zoo in Smithsonian Magazine. It was made by the very talents Sarah Joseph and Jon Betz. Thanks so much to everyone at Smithsonian Magazine for capturing our lab so well!


Two new Leftwich Lab papers out this summer 

The first describes the geometry of the California sea lion foreflipper:

Friedman, C., Joel, B. W., Schult, A. R., & Leftwich, M. C. (2015). Noninvasive 3D geometry extraction of a Sea lion foreflipper. Journal of Aero Aqua Bio-mechanisms, 4(1), 25-31. http://doi.org/10.5226/jabmech.4.25

And, the second is on the vertical shock tube at Los Alamos:

Mejia-Alvarez, R., Wilson, B., Leftwich, M. C., Martinez, A. A., & Prestridge, K. P. (2015). Design of a fast diaphragmless shock tube driver. Shock Waves, 1-16. doi: 10.1007/s00193-015-0579-y

Congrats to Alexa (the Engineers’ Council President) on organizing a successful Engineers’ Ball. Here is Megan having a great time with some of the Leftwich Lab undergrads (and CJ).

 

 

 

 

 

 

 


Leftwich Lab work highlighted in the 2014 AIAA Aerospace Review 

Thanks to the Fluid Dynamics Technical Committee for including our work on sea lions in this year’s Year In Review article. Our images even made the cut! Great work, team (especially Ken and Josh).

The Leftwich lab travelled to San Francisco for the 67th APS DFD meeting last month. In all, we presented 4 abstracts (and had a great time, too!):

Bioinspiration & Biomimetics paper 

Chen’s new paper is out in Bioinspiration and Biomimetics. Great work!

Megan Goes to China 

IMG_0465

Megan attended the 4th International Conference on Experimental Fluid Mechanics in Beijing, China. She was awarded the Young Researcher Award for her (and Colin and Danielle’s) contribution:

Leftwich, M.C., Parker, C. and Barskey, D., (2014) “Phase averaged wake measurements of Vertical Axis Wind Turbines,” Proceedings of the 4th International Conference on Experimental Fluid Mechanics.

Thanks to Jinjun Wong and everyone else at BUAA.

 

 

 

 


Leftwich Lab at the Lauder Lab

Andrea is spending this summer visiting Professor George Lauder at Harvard. She is getting some neat data investigating the role of input perturbations on unsteady propulsive surfaces. While at the World Congress of Biomechanics, we visited Prof. Lauder’s lab and got to meet his great white shark specimen. Thanks, George!

 

 

 

 

 

 

 

 

 


New Sea lion video

Check out Ken’s new sea lion video on the research page!

Construction of the SEH is well underway! The MAE 3126 class was treated to a tour of the facility complete with co-gen system and strong wall visits. Professor Plesniak came along and we visited the future location of the Leftwich/Plesniak Lab! Thanks to Clark Construction for the time and access!

 

 

 

 

 


AlexaPoster

Great job, Alexa Baumer, at this years BMES SEMABECC on October 25. She presented the following poster:

Baumer, A., Lehn, A. and Leftwich, M. C. (2013) “The role of amniotic fluid in force transfer during human birth.” Bulletin of the 2013 Southeast & Mid-Atlantic Biomedical Engineering Regional Career Conference (poster).

The Leftwich Lab has a working wind tunnel! It is humming along creating beautiful uniform flow and just waiting for experiments. Thanks to Zack, Bola, Prem, Adam and Danielle for their hard work to get it up and running. It took all summer, but they completed it with one day to spare. Great work! We’ll be running our first experiments this semester.
