SUMMARY:Department Seminar: Dr Jasmine Nirody
DESCRIPTION:\n\nPLEASE NOTE: This seminar is a hybrid event taking place in
 -person and online. You can choose to order an in-person ticket or a virtu
 al attendance ticket when registering to attend.\nFor those attending in p
 erson\, refreshments will be served immediately after this seminar in RSM 
 3.24 (Staff Common Room).\nTitle:\nA tale of two motilities: adaptive loco
 motion in complex\, changing environments\nAbstract:\nNatural environments
  are heterogeneous and can fluctuate with time. As such\, biomechanical sy
 stems from proteins to whole organisms have developed strategies to sense 
 and deal with considerable spatial and temporal variability.\nI will discu
 ss two (quite different!) broadly successful locomotive modes: flagellated
  motility in bacteria and walking in panarthropods. (1) A bacterium’s li
 fe can be complicated: it must swim through fluids of varying viscosity as
  well as interact with surfaces and other bacteria. We characterize the me
 chanosensitive adaptation in bacterial flagella that facilitates these tra
 nsitions by using magnetic tweezers to manipulate external torque on the b
 acterial flagellar motor. Our model for the dynamics of load-dependent ass
 embly in the flagellar motor illustrates how this nanomachine allows bacte
 ria to adapt to changes in their surroundings. (2) Panarthropods are a div
 erse clade containing insects\, crustaceans\, myriapods and tardigrades. W
 e show that inter-limb coordination patterns in freely-behaving tardigrade
 s replicate several key features of walking in insects across a range of s
 peeds and substrates.\nIn light of these functional similarities\, we prop
 ose a simple universal locomotor circuit capable of robust multi-legged co
 ntrol across body sizes\, skeletal structures\, and habitats.\nBiography:\
 nJasmine Nirody is an Assistant Professor in Organismal Biology and Anatom
 y at the University of Chicago. She received a BA in Mathematics and Biolo
 gy from New York University\, and PhD in Biophysics from the University of
  California\, Berkeley. Most recently\, she was an Independent Fellow in P
 hysics and Biology at The Rockefeller University and a Post-Doctoral Resea
 rch Fellow of All Souls College\, University of Oxford.\nHer research sits
  at the interface of biophysics\, behaviour\, and evolution. She studies t
 he physical interactions between organisms and their environments\, and ho
 w these interactions shape organismal form and behaviour. Her work focuses
  on understanding morphology and performance within the context of an orga
 nism’s ecology and evolutionary history.\nShe has worked with a wide ran
 ge of organisms\, and her current research is grounded in (though certainl
 y not limited to) two broadly-defined systems: flagellated bacteria and wa
 lking panarthropods.\n\n
